MySQL @SQL_MODE
Installing MySQL Workbench 8 on Windows, we discovered that the default configuration no longer sets ONLY_FULL_GROUP_BY as part of the default SQL_MODE parameter value. While I’ve written a stored function to set the SQL_MODE parameter value for a session, some students didn’t understand that such a call is only valid in the scope of a connection to the database server. They felt the function didn’t work because they didn’t understand the difference between connecting to the MySQL CLI and clicking the lightening bolt in MySQL Workbench.
So, here are the instructions to reset the default SQL_MODE parameter value for Windows. You need to edit the setting in the my.ini file, which is in the C:\ProgramData\MySQL\MySQL Server 8.0 directory. The default installation will have the following:
# Set the SQL mode to strict sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION" |
You need to change it to the following in an editor with Administrative privileges:
# Set the SQL mode to strict sql-mode="STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION,ONLY_FULL_GROUP_BY" |
Then, you need to connect to the services by launching services.msc from the command prompt. In the list of services find MYSQL80 service and restart it. You can verify it by connecting to the MySQL 8.0.* server and running the following SQL query:
SELECT @@SQL_MODE: |
That’s how you convert Windows to use only traditional group by behaviors in SQL. As always, I hope this helps those looking for a solution.
Updating SQL_MODE
This is an update for MySQL 8 Stored PSM to add the ONLY_FULL_GROUP_BY mode to the global SQL_MODE variable when it’s not set during a session. Here’s the code:
/* Drop procedure conditionally on whether it exists already. */ DROP PROCEDURE IF EXISTS set_full_group_by; /* Reset delimter to allow semicolons to terminate statements. */ DELIMITER $$ /* Create a procedure to verify and set connection parameter. */ CREATE PROCEDURE set_full_group_by() LANGUAGE SQL NOT DETERMINISTIC SQL SECURITY DEFINER COMMENT 'Set connection parameter when not set.' BEGIN /* Check whether full group by is set in the connection and if unset, set it in the scope of the connection. */ IF EXISTS (SELECT TRUE WHERE NOT REGEXP_LIKE(@@SESSION.SQL_MODE,'ONLY_FULL_GROUP_BY')) THEN SET @@GLOBAL.SQL_MODE := CONCAT(@@SESSION.sql_mode,',ONLY_FULL_GROUP_BY'); END IF; END; $$ /* Reset the default delimiter. */ DELIMITER ; |
You can call the set_full_group_by procedure with the CALL command:
CALL set_full_group_by(); |
You can see the SQL_MODE variable with the following query:
SELECT @@GLOBAL.SQL_MODE; |
It’ll return:
+---------------------------------------------------------------+ | @@GLOBAL.SQL_MODE | +---------------------------------------------------------------+ | ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ENGINE_SUBSTITUTION | +---------------------------------------------------------------+ 1 row in set (0.00 sec) |
As always, I hope this helps those looking to solve this type of problem.
GROUP BY Quirk
It’s always interesting to see how others teach SQL courses. It can be revealing as to whether they understand SQL or only understand a dialect of SQL. In this case, one of my old students was taking a graduate course in SQL and the teacher was using MySQL. The teacher made an issue of using ANSI SQL:1999 or SQL3 and asked the following question, which I suspect is a quiz bank question from a textbook:
“How would you get all students’ names and for each student the number of courses that the
student has registered for?”
They referenced the MySQL 5.7 documentation for the GROUP BY and SQL:1999 as if MySQL implemented the ANSI SQL:1999 specification defined the standard. I didn’t know whether to laugh or cry because they were referring to MySQL 5.7 when we’re all using MySQL 8 and anybody who’s worked in more than MySQL knows that the behavior for a GROUP BY in MySQL can work without listing the necessary non-aggregated columns in the SELECT-list.
For example, their working solution, which is from the instructor and the author of their MySQL textbook the correct perspective of ANSI:1999 behavior. It doesn’t matter that their solution is actually based on ANSI:1992 not ANSI:1999 because it will only succeed because of a quirk of MySQL:
SELECT a.studentname , COUNT(b.courseid) FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid GROUP BY a.studentid; |
While it works in MySQL, it doesn’t work because it conforms to an ANSI standard. It works in MySQL, notwithstanding that standard because it violates the standard.
In Oracle, PostgreSQL, and SQL Server, it raises an exception. For example, Oracle raises the following exception:
SELECT a.studentname * ERROR at line 1: ORA-00979: not a GROUP BY expression |
The correct way to write the GROUP BY is:
SELECT a.studentname , COUNT(b.courseid) FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid INNER JOIN courses c ON b.courseid = c.courseid GROUP BY a.studentname; |
Then, it would return:
Student Name Course IDs ------------------------------ ---------- Montgomery Scott 1 Leonard McCoy 2 James Tiberus Kirk 3 |
For reference, here’s a complete test case for MySQL:
/* Drop table conditionally. */ DROP TABLE IF EXISTS students; /* Create table. */ CREATE TABLE students ( studentID int unsigned primary key auto_increment , studentName varchar(30)); /* Drop table conditionally. */ DROP TABLE IF EXISTS courses; /* Create table. */ CREATE TABLE courses ( courseid int unsigned primary key auto_increment , coursename varchar(40)); /* Drop table conditionally. */ DROP TABLE IF EXISTS registeredcourses; /* Create table. */ CREATE TABLE registeredcourses ( courseid int unsigned , studentid int unsigned ); /* Insert into students. */ INSERT INTO students ( studentName ) VALUES ('James Tiberus Kirk') ,('Leonard McCoy') ,('Montgomery Scott'); /* Insert into courses. */ INSERT INTO courses ( coursename ) VALUES ('English Literature') ,('Physics') ,('English Composition') ,('Botany') ,('Mechanical Engineering'); /* Insert into registeredcourses. */ INSERT INTO registeredcourses ( studentid , courseid ) VALUES (1,1) ,(1,3) ,(1,4) ,(2,2) ,(2,5) ,(3,4); /* Check global sql_mode to ensure only_full_group_by is set. */ SELECT @@GLOBAL.SQL_MODE; /* Query with a column not found in the SELECT-list. */ SELECT a.studentname , COUNT(b.courseid) FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid GROUP BY a.studentid; /* Query consistent with ANSI SQL:1992 */ SELECT a.studentname , COUNT(b.courseid) FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid INNER JOIN courses c ON b.courseid = c.courseid GROUP BY a.studentname; |
and, another complete test case for Oracle:
/* Drop tabhe unconditionallly. */ DROP TABLE students; /* Create table. */ CREATE TABLE students ( studentID NUMBER PRIMARY KEY , studentName VARCHAR(30)); /* Drop table unconditionally. */ DROP TABLE courses; /* Create table. */ CREATE TABLE courses ( courseid NUMBER PRIMARY KEY , coursename VARCHAR(40)); /* Drop table unconditionally. */ DROP TABLE registeredcourses; /* Create table. */ CREATE TABLE registeredcourses ( courseid NUMBER , studentid NUMBER ); /* Insert values in student. */ INSERT INTO students ( studentid, studentName ) VALUES (1,'James Tiberus Kirk'); INSERT INTO students ( studentid, studentName ) VALUES (2,'Leonard McCoy'); INSERT INTO students ( studentid, studentName ) VALUES (3,'Montgomery Scott'); /* Insert values in courses. */ INSERT INTO courses ( courseid, coursename ) VALUES (1,'English Literature'); INSERT INTO courses ( courseid, coursename ) VALUES (2,'Physics'); INSERT INTO courses ( courseid, coursename ) VALUES (3,'English Composition'); INSERT INTO courses ( courseid, coursename ) VALUES (4,'Botany'); INSERT INTO courses ( courseid, coursename ) VALUES (5,'Mechanical Engineering'); /* Insert values into registeredcourses. */ INSERT INTO registeredcourses ( studentid, courseid ) VALUES (1,1); INSERT INTO registeredcourses ( studentid, courseid ) VALUES (1,3); INSERT INTO registeredcourses ( studentid, courseid ) VALUES (1,4); INSERT INTO registeredcourses ( studentid, courseid ) VALUES (2,2); INSERT INTO registeredcourses ( studentid, courseid ) VALUES (2,5); INSERT INTO registeredcourses ( studentid, courseid ) VALUES (3,4); /* Non-ANSI SQL GROUP BY statement. */ SELECT a.studentname , COUNT(b.courseid) FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid GROUP BY a.studentid; /* ANSI SQL GROUP BY statement. */ SELECT a.studentname AS "Student Name" , COUNT(b.courseid) AS "Course IDs" FROM students a INNER JOIN registeredcourses b ON a.studentid = b.studentid INNER JOIN courses c ON b.courseid = c.courseid GROUP BY a.studentname; |
I hope this helps those learning the correct way to write SQL.
MySQL PNG Files
LAMP (Linux, Apache, MySQL, Perl/PHP/Python) Architecture is very flexible. All the components can be positioned on the same server or different servers. The servers are divided into two types. The types are known as the Application or database tiers. Generally, the application tier holds the Apache Server, any Apache Modules, and local copies of Server Side Includes (SSI) programs.
In many development environments, you also deploy the client to the same machine. This means a single machine runs the database server, the application server, and the browser. The lab for this section assumes these configurations.
Before you test an installation, you should make sure that you’ve started the database and Apache server. In an Oracle LAMP configuration (known as an OLAP – Oracle, Linux, Apache, Perl/PHP/Python), you must start both the Oracle Listener and database. MySQL starts the listener when you start the database. You must also start the Apache Server. The Apache Server also starts an Apache Listener, which listens for incoming HTTP/HTTPS requests. It listens on Port 80
unless you override that setting in the httpd.conf
file.
The URI reaches the server and is redirected to an Apache Module based on configuration information found in the httpd.conf
file. Spawned or child processes of the Apache Module then read programs into memory from the file system and run them. If you’ve uploaded a file the locally stored program can move it from a secure cache location to another local area for processing. The started programs can run independently or include other files as libraries, and they can communicate to the database server.
Working though PHP test cases against the MySQL database for my AlmaLinux installation and configuration, I discovered that the php-gd library weren’t installed by default. I had to add it to get my PHP programs to upload and display PNG files.

The balance of this page demonstrates how to upload, store, and manage Text (Character Large Data Streams) and BLOBs (Binary Large Objects). It provides MySQL equivalent instructions to those for manaing LOBs in an Oracle database. As covered in Chapter 8 in my Oracle Database 11g PL/SQL Programming book.
Before you begin these steps, you should have already installed Zend Server Community Edition. If you haven’t done so, please click here for instructions.
Create directories or folders, and position code →
This section provides you with instructions on how to position the code components in Windows, at least for the newbie. If you’re on Linux, you probably know how to do most if not all of this already. Likewise, if you already know how to put things in the right place, please choose your own locations.
- Create a
LOB
(Large Object) directory for the PHP files inside thehtdocs
directory.
- You can down the MySQL PHP Upload LOB Web Code zip file and unzip it into the directory you just created. It can co-exist with the Oracle equivalent if you’ve done that already.

- Create a
temp
directory for the upload target location, as qualified in the PHP code. The PHP code works regardless of whether you’re on Windows or Linux, but it does depend on the creation of this directory.
- Create a directory or folder for the large file source directories. This directory is probably on your test machine (laptop) but it mimics a client laptop and would work if your server was on a different machine.
- Inside the Upload directory, you should create the following two directories:
- You should download the CLOB Text File zip file and unzip it into the
textfiles
directory; then download the BLOB Image File zip file and unzip it into the imagefiles
directory.Assuming you’ve downloaded the zip files and extracted them into the correct locations, this section is done.
Prepare the MySQL database →
This section provides you with instructions on how to ensure everything will work once the PHP programs call the database. Even if you have one of my sample Video Store databases, you should verify and add appropriate columns. This post assumes you’ve downloaded the one of my basic Video Store models
- Navigate to the directory that you created for SQL scripts, which should be
/home/student/Data/mysql
. In that directory at the command prompt, connect as thestudent
user, which should be student. You connect to the MySQL database, with the following syntax as student (if you need more help, check this blog post on configuring MySQL).
mysql -ustudent -pstudent |
Once connected to the database, you run the files to create the database, like:
mysql> source /Data/mysql/create_mysql_store.sql mysql> source /Data/mysql/seed_mysql_store.sql |
- Navigate to the directory that you created for SQL scripts, which should be
/home/student/Data/mysql
. In that directory at the command prompt, connect as thestudent
user, or whichever account you’re using. You should confirm that you have aitem_desc
column ofTEXT
data type, and anitem_blob
column ofMEDIUMBLOB
type in theitem
table. If you don’t have those columns, you can add them with the following statement:
ALTER TABLE item ADD (item_desc TEXT, item_blob MEDIUMBLOB); |
After ensuring that you have those two columns, you’ve completed this section.
Test the Configuration →
This section shows you how to test all that you’ve done. It works provided you created the directories and extracted the zip file contents to their respective directories. The virtual URL actually maps to the /var/www/html/lob
directory.
- Enter the
http://localhost/lob/UploadItemDescMySQLForm.htm
URL, and complete the form by choosing a validitem_id
column value and text file from your/home/student/Upload/TextFiles
directory. Then, click the Upload File button (you can see a larger version of the image by clicking on it).
- This page displays after you successfully upload the text file to the database.
- Enter the
http://localhost/lob/UploadItemBlobFormMySQL.htm
URL, and complete the form by choosing a validitem_id
column value and image file from your/home/student/Upload/ImageFiles
directory. Then, click the Upload File button (you can see a larger version of the image by clicking on it).
- This page displays after you successfully upload the image file to the database.
Troubleshooting the Configuration →
This section shows you how to check why something isn’t working.
- The first thing to check are the credentials. They’re in the
MySQLCredentials.inc
file. They’re posted with alocalhost
machine name,student
username,student
password, andsampledb
database.
- Not to be funny, but the second thing to check are credentials. Specifically, you need to check the credentials in the
ConvertBlobToImage.php
file. They’re individually entered in the connect string of this file because otherwise they put something in front of the header, which is disallowed to render the image.
- Check to see if the text or image file made it to the
/var/www/html/lob/temp
directory. If they made it that far but no further, check to see if you have valid procedures in thestudent
schema.
- Check whether the
TEXT
andMEDIUMBLOB
are loaded into the database. You use theLENGTH
function, like this:
SELECT i.item_id , length(i.item_desc) , length(i.item_blob) FROM item i WHERE i.item_desc IS NOT NULL OR i.item_blob IS NOT NULL; |
- Check if the
item_id
value is found in the list of values.
- If you’re stumped, add a comment and explain what’s up.
If you find any problems, please let me know. I’ll be happy to fix them.

I used Oracle Database 11g XE in this instance to keep the footprint as small as possible. It required a few tricks and discovering the missing library that caused folks grief eleven years ago. I build another with a current Oracle Database XE after the new year.
If you see something that I missed or you’d like me to add, let me know. As time allows, I’ll try to do that. Naturally, the post will get updates as things are added later.
AlmaLinux+Java+MySQL
AlmaLinux generally has Java installed. You can check whether java is installed with this command:
which -a java |
It should return:
/usr/bin/java |
Then, you can check the Java version with this command:
java -version |
For AlmaLinux 9, it should return:
openjdk version "11.0.17" 2022-10-18 LTS OpenJDK Runtime Environment (Red_Hat-11.0.17.0.8-2.el9_0) (build 11.0.17+8-LTS) OpenJDK 64-Bit Server VM (Red_Hat-11.0.17.0.8-2.el9_0) (build 11.0.17+8-LTS, mixed mode, sharing) |
Next, you check whether javac is installed. You can use the which command to determine whether it is installed. Generally, its not installed and you use this command to
sudo dnf search jdk | egrep -- '-17' |
It should return:

After installing javac, you can verify it with the which command, and check the version with the javac utility.
which -a javac |
It should return:
/usr/bin/javac |
Then, you can check the Java version with this command:
java -version |
For AlmaLinux 9, it should return:
javac 17.0.5 |
Now, you need to download and install the jdk with the dnf utility. You download the jdk package with the wget utility.
wget https://download.oracle.com/java/17/latest/jdk-17_linux-x64_bin.rpm |
It will generate the following console output:

After installing everything, you need to set the default Java. You can discover the available Java versions with the following command:
sudo alternatives --config java |
It should return a list and the ability to select one by using the “Selection” number. I recommend you chose #2.
There are 3 programs which provide 'java'. Selection Command ----------------------------------------------- 1 java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.17.0.8-2.el9_0.x86_64/bin/java) 2 java-17-openjdk.x86_64 (/usr/lib/jvm/java-17-openjdk-17.0.5.0.8-2.el9_0.x86_64/bin/java) *+ 3 /usr/java/jdk-17.0.5/bin/java Enter to keep the current selection[+], or type selection number: 2 |
Then, you can check the Java version with this command:
java -version |
Now, it should return:
openjdk version "17.0.5" 2022-10-18 LTS OpenJDK Runtime Environment (Red_Hat-17.0.5.0.8-2.el9_0) (build 17.0.5+8-LTS) OpenJDK 64-Bit Server VM (Red_Hat-17.0.5.0.8-2.el9_0) (build 17.0.5+8-LTS, mixed mode, sharing) |
You should define the $JAVA_HOME environment variable in the /etc/profile file. Sometimes, it is also appropriate to include it in your .bashrc file.
export set JAVA_HOME="/usr/lib/jvm/java-17-openjdk-17.0.5.0.8-2.el9_0.x86_64/bin" |
You should also add it to your $PATH variable in your .bashrc file, like:
export set PATH=$PATH:$JAVA_HOME |
Now, let’s write the basic “Hello World” program in Java:
// Define the Java program. public class HelloWorld { public static void main(String[] args) { System.out.println("Hello World!"); } } |
Compile it with:
javac HelloWorld.java |
Run it with the java command:
java HelloWorld |
It prints:
Hello World! |
Let’s download the MySQL/J Connector from the MySQL website, where we con select the operating system and its version, as shown in the image.
After you download the mysql-connector-j RPM package, you can install it with the following dnf command:
sudo dnf install -y mysql-connector-j-8.0.31-1.el9.noarch.rpm |

You should add the $CLASSPATH to your .bashrc file. Add the following line to your .bashrc file and resource your .bashrc file to test the JDBC driver.
export set CLASSPATH="/usr/share/java/mysql-connector-j.jar:." |
Let’s write a slightly larger Java program that tests connectivity to the MySQL database, like:
// Import classes. import java.sql.*; /* You can't include the following on Linux without raising an exception. */ // import com.mysql.jdbc.Driver; public class MySQLConnector { public MySQLConnector() { /* Declare variables that require explicit assignments because they're addressed in the finally block. */ Connection conn = null; Statement stmt = null; ResultSet rset = null; /* Declare other variables. */ String url; String username = "student"; String password = "student"; String database = "studentdb"; String hostname = "localhost"; String port = "3306"; String sql; /* Attempt a connection. */ try { // Set URL. url = "jdbc:mysql://" + hostname + ":" + port + "/" + database; // Create instance of MySQLDriver. Class.forName ("com.mysql.cj.jdbc.Driver").newInstance(); conn = DriverManager.getConnection (url, username, password); // Query the version of the database. sql = "SELECT version()"; stmt = conn.createStatement(); rset = stmt.executeQuery(sql); System.out.println ("Database connection established"); // Read row returns for one column. while (rset.next()) { System.out.println("MySQLDriver Version [" + rset.getString(1) + "]"); } } catch (SQLException e) { System.err.println ("Cannot connect to database server:"); System.out.println(e.getMessage()); } catch (ClassNotFoundException e) { System.err.println ("Cannot find MySQL driver class:"); System.out.println(e.getMessage()); } catch (InstantiationException e) { System.err.println ("Cannot instantiate class:"); System.out.println(e.getMessage()); } catch (IllegalAccessException e) { System.err.println ("Illegal access exception:"); System.out.println(e.getMessage()); } finally { if (conn != null) { try { rset.close(); stmt.close(); conn.close(); System.out.println ("Database connection terminated"); } catch (Exception e) { /* ignore close errors */ } } } } /* Unit test. */ public static void main(String args[]) { new MySQLDriver(); } } |
Just a note, there’s a deprecated behavior introduced in MySQL 8.0.24, which produces the following error message when compiled looking for deprecation:
javac -Xlint:deprecation MySQLDriver.java |
It produces the following error message, which I hope to sort and update later in the week:
MySQLDriver.java:30: warning: [deprecation] newInstance() in Class has been deprecated Class.forName ("com.mysql.cj.jdbc.Driver").newInstance(); ^ where T is a type-variable: T extends Object declared in class Class 1 warning |
The code does compile because the deprecation is only a warning. When you run the program, like:
java MySQLDriver |
It returns, confirming a connection to the MySQL database:
Database connection established MySQLDriver Version [8.0.30] Database connection terminated |
As always, I hope this helps those trying to sort out new behaviors.
AlmaLinux MySQL Workbench
AlmaLinux doesn’t natively support MySQL Workbench but these notes will help you install it. The great news is that MySQL Workbench works perfectly once you’ve installed all the dependent libraries. It’ll look like the following:
Disclaimer of sorts:
AlmaLinux is an open-source, community-driven project that intends to fill the gap left by the demise of the CentOS stable release. AlmaLinux is a 1:1 binary compatible fork of RHEL® 9 and it is built by the AlmaLinux OS Foundation as a standalone, completely free OS. The AlmaLinux OS Foundation will support future RHEL® releases by updating AlmaLinux. Ongoing development efforts are governed by the members of the community.
You can download MySQL Workbench from the following website:
https://dev.mysql.com/downloads/workbench |
When you open this page, select the Red Hat Enterprise Linux 9 / Oracle Linux 9 (x86, 64-bit), RPM Package from the dropdown menu. Then, click the Download button. You may be prompted for your credentials or to create new credentials, but you can skip that by clicking on the No thanks, just start my download link.
When the download completes, open a terminal session as the student user. Navigate to the Downloads directory with the following command:
cd $HOME/Downloads |
List the files in the $HOME/Downloads directory and you should see:
mysql-workbench-community-8.0.31-1.el9.x86_64.rpm |
As the sudoer user or root, run the following command (naturally, exclude sudo if you’re the root user):
sudo dnf install -y mysql-workbench-community-8.0.31-1.el9.x86_64.rpm |
It will most likely fail with an error message like this:
Last metadata expiration check: 2:50:04 ago on Thu 17 Nov 2022 09:33:15 AM EST. Error: Problem: conflicting requests - nothing provides gtkmm30-devel needed by mysql-workbench-community-8.0.31-1.el9.src - nothing provides libzip-devel needed by mysql-workbench-community-8.0.31-1.el9.src - nothing provides proj-devel needed by mysql-workbench-community-8.0.31-1.el9.src - nothing provides swig >= 3.0 needed by mysql-workbench-community-8.0.31-1.el9.src (try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages) |
AlmaLinux doesn’t install these prerequisite packages. You’ll need to resolve these dependencies by installing them in the right order and groups before you can run the MySQL Workbench packages.
You can discover missing packages at the pkgs.org website. You need to resolve all four prerequisites before installing MySQL Workbench.
- Let’s start with the gtkmm30-devel package, which has eight separate dependencies. Assuming you’re still in your $HOME/Downloads directory, you can run the following command to get the gtkmm30-devel for AlmaLinux 9:
wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/gtkmm30-devel-3.24.5-1.el9.x86_64.rpm
It downloads the following package:
gtkmm30-devel-3.24.5-1.el9.x86_64.rpm
If you attempt to run it, the gtkmm30-devel package raises the following errors:
sudo dnf install -y gtkmm30-devel-3.24.5-1.el9.x86_64.rpm Last metadata expiration check: 0:41:13 ago on Thu 17 Nov 2022 02:39:59 PM EST.

While you only get four errors, there are more packages required. You need to use the wget utility to download these packages. I would recommend you create a temporary gtkmm30 subdirectory inside your $HOME/Downloads directory and change to that directory before downloading these files.
wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/atkmm-devel-2.28.2-2.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/cairomm-devel-1.14.2-10.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/AppStream/x86_64/os/Packages/gdk-pixbuf2-devel-2.42.6-2.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/glibmm24-devel-2.66.1-1.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/AppStream/x86_64/os/Packages/gtk3-devel-3.24.31-2.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/pangomm-devel-2.46.1-1.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/libsigc++20-devel-2.10.7-2.el9.x86_64.rpm
You need to run these as a set of prerequisites, so from your gtkmm30 subdirectory use the following dnf command as the sudoer user:
sudo dnf install -y *.rpm

All that done and you’ve only got the first of four dependencies resovled.
- Next, start with the libzip-devel package, which has a couple dependencies. Assuming you’re still in your $HOME/Downloads directory, you can run the following command to get the libzip-devel and its prerequisite packages for AlmaLinux 9:
wget https://repo.almalinux.org/almalinux/9/CRB/x86_64/os/Packages/libzip-devel-1.7.3-7.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/AppStream/x86_64/os/Packages/cmake-filesystem-3.20.2-7.el9.x86_64.rpm wget https://repo.almalinux.org/almalinux/9/AppStream/x86_64/os/Packages/libzip-1.7.3-7.el9.x86_64.rpm
You can run the prerequisites with the following command:
sudo dnf install -y cmake*.rpm libzip-1.7.3*.rpm
Now, you can run the libzip-devel package with this syntax:
sudo dnf install -y libzip-devel*.rpm
Having resolved the two dependencies, you can install the compression development kit. This completes the second step.
-
Next, you need to apply the proj_devel package for AlmaLinux 9:
wget https://download-ib01.fedoraproject.org/pub/epel/9/Everything/x86_64/Packages/p/proj-devel-8.2.0-1.el9.x86_64.rpm
Now, you can run the proj-devel package with this syntax:
sudo dnf install -y proj-devel-8.2.0-1.el9.x86_64.rpm
-
Next, you need to apply the swig packages for AlmaLinux 9:

That displays the nine-dots for Show Applications icon. Click the Show Applications icon and choose the MySQL Workbench icon to launch MySQL Workbench.
You’ll be prompted with the following dialog. Just click Don’t show this message again checkbox and the OK button to launch MySQL Workbench.
As always, I hope this helps those looking to solve a real problem.
AlmaLinux MySQL+Perl
A quick primer on Perl programs connecting to the MySQL database. It’s another set of coding examples for the AlmaLinux instance that I’m building for students. This one demonstrates basic Perl programs, connecting to MySQL, returning data sets by reference and position, dynamic queries, and input parameters to dynamic queries.
- Naturally, a hello.pl is a great place to start:
#!/usr/bin/perl # Hello World program. print "Hello World!\n";
After setting the permissions to -rwxr-xr-x. with this command:
chmod 755 hello.pl
You call it like this from the Command-Line Interface (CLI):
./hello.pl
It prints:
Hello World!
- Next, a connect.pl program lets us test the Perl::DBI connection to the MySQL database.
#!/usr/bin/perl # Import libraries. use strict; use warnings; use v5.10; # for say() function use DBI; # Print with say() function message. say "Perl MySQL Connect Attempt."; # MySQL data source name should have a valid database as the # third argument; this uses the sakila demo database. my $dsn = "DBI:mysql:sakila"; # Local variables to build the connection string. my $username = "student"; my $password = "student"; # Set arguments for MySQL database error management. my %attr = ( PrintError=>0, # turn off error reporting via warn() RaiseError=>1); # turn on error reporting via die() # Create connction with a data source name, user name and password. my $dbh = DBI->connect($dsn,$username,$password, \%attr); # Print with say() function valid connection message. say "Connected to the MySQL database.";
After setting the permissions to -rwxr-xr-x. you call it with this CLI command:
./connect.pl
It prints:
Perl MySQL Connect Attempt. Connected to the MySQL database.
- After connecting to the database lets query a couple columns by reference notation in a static.pl program. This one just returns the result of the MySQL version() and database() functions.
#!/usr/bin/perl # Import libraries. use strict; use warnings; use v5.10; # for say() function use DBI; # Print with say() function message. say "Perl MySQL Connect Attempt."; # MySQL data source name must have a valid database as the # third argument; this uses the sakila demo database. my $dsn = "DBI:mysql:sakila"; # Local variables to build the connection string. my $username = "student"; my $password = "student"; # Set arguments for MySQL database error management. my %attr = ( PrintError=>0, # turn off error reporting via warn() RaiseError=>1); # turn on error reporting via die() # Create connction with a data source name, user name and password. my $dbh = DBI->connect($dsn,$username,$password, \%attr); # Creaet a static SQL statement or query. my $sth = $dbh->prepare("SELECT version() AS version \ , database() AS db_name"); # Execute the static statement. $sth->execute() or die "Execution failed: $dbh->errstr()"; # Read data and print by reference. print "----------------------------------------\n"; while (my $ref = $sth->fetchrow_hashref()) { print "MySQL Version: $ref->{'version'}\nMySQL Database: $ref->{'db_name'}\n"; } print "----------------------------------------\n"; # Close the statement. $sth->finish; # Disconnect from database connection. $dbh->disconnect(); # Print with say() function valid connection message. say "Connected to the MySQL database.";
After setting the permissions to -rwxr-xr-x. you call it with this CLI command:
./static.pl
It prints:
Perl MySQL Connect Attempt. ---------------------------------------- MySQL Version: 8.0.30 MySQL Database: sakila ---------------------------------------- Connected to the MySQL database.
- After connecting to the database and securing variables by reference notation, lets return the value as an array of rows in a columns.pl program. This one just returns data from the film table of the sakila database. It is a static query because all the values are contained inside the SQL statement.
#!/usr/bin/perl # Import libraries. use strict; use warnings; use v5.10; # for say() function use DBI; # Print with say() function message. say "Perl MySQL Connect Attempt."; # MySQL data source name must have a valid database as the # third argument; this uses the sakila demo database. my $dsn = "DBI:mysql:sakila"; # Local variables to build the connection string. my $username = "student"; my $password = "student"; # Set arguments for MySQL database error management. my %attr = ( PrintError=>0, # turn off error reporting via warn() RaiseError=>1); # turn on error reporting via die() # Create connction with a data source name, user name and password. my $dbh = DBI->connect($dsn,$username,$password, \%attr); # Creaet a static SQL statement or query. my $sth = $dbh->prepare("SELECT title \ , release_year \ , rating \ FROM film \ WHERE title LIKE 'roc%'"); # Execute the static statement. $sth->execute() or die "Execution failed: $dbh->errstr()"; # Read data and print by comma-delimited row position. print "----------------------------------------\n"; while (my @row = $sth->fetchrow_array()) { print join(", ", @row), "\n"; } print "----------------------------------------\n"; # Close the statement. $sth->finish; # Disconnect from database connection. $dbh->disconnect(); # Print with say() function valid connection message. say "Connected to the MySQL database.";
After setting the permissions to -rwxr-xr-x. you call it with this CLI command:
./columns.pl
It prints:
Perl MySQL Connect Attempt. ---------------------------------------- ROCK INSTINCT, 2006, G ROCKETEER MOTHER, 2006, PG-13 ROCKY WAR, 2006, PG-13 ---------------------------------------- Connected to the MySQL database.
- After connecting to the database and securing variables by reference notation, lets return the value as an array of rows in a dynamic.pl program. This one just returns data from the film table of the sakila database. It is a dynamic query because a string passed to the execute method and that value is bound to a ? placeholder in the SQL statement.
#!/usr/bin/perl # Import libraries. use strict; use warnings; use v5.10; # for say() function use DBI; # Print with say() function message. say "Perl MySQL Connect Attempt."; # MySQL data source name must have a valid database as the # third argument; this uses the sakila demo database. my $dsn = "DBI:mysql:sakila"; # Local variables to build the connection string. my $username = "student"; my $password = "student"; # Set arguments for MySQL database error management. my %attr = ( PrintError=>0, # turn off error reporting via warn() RaiseError=>1); # turn on error reporting via die() # Create connction with a data source name, user name and password. my $dbh = DBI->connect($dsn,$username,$password, \%attr); # Creaet a static SQL statement or query. my $sth = $dbh->prepare("SELECT title \ , release_year \ , rating \ FROM film \ WHERE title LIKE CONCAT(?,'%')"); # Execute the dynamic statement by providing an input parameter. $sth->execute('roc') or die "Execution failed: $dbh->errstr()"; # Read data and print by comma-delimited row position. print "----------------------------------------\n"; while (my @row = $sth->fetchrow_array()) { print join(", ", @row), "\n"; } print "----------------------------------------\n"; # Close the statement. $sth->finish; # Disconnect from database connection. $dbh->disconnect(); # Print with say() function valid connection message. say "Connected to the MySQL database.";
After setting the permissions to -rwxr-xr-x. you call it with this CLI command:
./dynamic.pl
It prints:
Perl MySQL Connect Attempt. ---------------------------------------- ROCK INSTINCT, 2006, G ROCKETEER MOTHER, 2006, PG-13 ROCKY WAR, 2006, PG-13 ---------------------------------------- Connected to the MySQL database.
- After connecting to the database and securing variables by reference notation, lets return the value as an array of rows in a input.pl program. This one just returns data from the film table of the sakila database. It is a dynamic query because an input parameter is passed to a local variable and the local variable is bound to a ? placeholder in the SQL statement.
#!/usr/bin/perl # Import libraries. use strict; use warnings; use v5.10; # for say() function use DBI; # Get the index value of the maximum argument in the # argument. my $argc = $#ARGV; # Accept first argument value as parameter. my $param = $ARGV[$argc]; # Verify variable value assigned. if (not defined $param) { die "Need parameter value.\n"; } # Print with say() function message. say "Perl MySQL Connect Attempt."; # MySQL data source name must have a valid database as the # third argument; this uses the sakila demo database. my $dsn = "DBI:mysql:sakila"; # Local variables to build the connection string. my $username = "student"; my $password = "student"; # Set arguments for MySQL database error management. my %attr = ( PrintError=>0, # turn off error reporting via warn() RaiseError=>1); # turn on error reporting via die() # Create connction with a data source name, user name and password. my $dbh = DBI->connect($dsn,$username,$password, \%attr); # Creaet a static SQL statement or query. my $sth = $dbh->prepare("SELECT title \ , release_year \ , rating \ FROM film \ WHERE title LIKE CONCAT(?,'%')"); # Execute the static statement. $sth->execute($param) or die "Execution failed: $dbh->errstr()"; # Read data and print by comma-delimited row position. print "----------------------------------------\n"; while (my @row = $sth->fetchrow_array()) { print join(", ", @row), "\n"; } print "----------------------------------------\n"; # Close the statement. $sth->finish; # Disconnect from database connection. $dbh->disconnect(); # Print with say() function valid connection message. say "Connected to the MySQL database.";
After setting the permissions to -rwxr-xr-x. you call it with this CLI command:
./input.pl ta
It prints:

I think these examples cover most of the basic elements of writing Perl against the MySQL database. If I missed something you think would be useful, please advise. As always, I hope this helps those working with the MySQL and Perl products.
AlmaLinux LAMP
After installing and configuring MySQL 8.0.30, I installed the Apache Web Server, PHP and the MySQLi packages. Here are the step-by-step instructions after installing and configuring the MySQL Server and provisioning a student user and the sakila and studentdb databases (blog for those steps). After installing the major components, I completed the HTTPS configuration steps for Apache 2.
The installation steps are:
- Install the Apache packages as the sudoer user with this command:
sudo dnf install -y httpd
- Enable Apache as the sudoer user with this command:
chkconfig httpd on
This returns the following completion message:
Note: Forwarding request to 'systemctl enable httpd.service'. Created symlink /etc/systemd/system/multi-user.target.wants/httpd.service → /usr/lib/systemd/system/httpd.service.
A quick Linux syntax note in the event you want to confirm the link or link target later. You can use the following syntax as a sudoer user to find the link:
ls `find /etc -type l | grep httpd.service 2>/dev/null`
and the following syntax as a sudoer user to find the link’s target:
readlink `find /etc -type l | grep httpd.service 2>/dev/null`
- You still need to start the Apache service unless you reboot the operating system as the sudoer user with this command:
apachectl start
- At this point, you need to check the firewall settings because Apache can’t even read localhost at this point. If you’re new to these firewall commands, you should consider reviewing Korbin Brown’s tutorial. As the sudoer user check the Apache available services with this command:
firewall-cmd --zone=public --list-services
It should return:
cockpit dhcpv6-client ssh
Add the following services and ports with these commands:
firewall-cmd --zone=public --add-port 80/tcp --permanent firewall-cmd --zone=public --add-port 443/tcp --permanent firewall-cmd --zone=public --add-port 8080/tcp --permanent firewall-cmd --zone=public --add-service=http --permanent firewall-cmd --zone=public --add-service=https --permanent
Check the open ports with the following command:
firewall-cmd --zone=public --list-ports
It should return:
80/tcp 443/tcp 8080/tcp
Check the open services with the following command:
firewall-cmd --zone=public --list-services
It should return:
cockpit dhcpv6-client http https ssh
- Create the hello.htm file in the /var/www/html directory as the root user:
Restart the Apache service as the sudoer user:
apache restart
<html> <body> Hello World! </body> </html>
Then, you can launch the Firefox browser and type the following:
localhost/hello.htm
It should print “Hello World!” in the browser.
- Install the php package as the sudoer user with the following command:
sudo dnf install -y php
Create the info.php file in the /var/www/html directory as the root user:
<?php phpinfo(); ?>
apache restart
Then, you can launch the Firefox browser and type the following:
localhost/info.php
It should return the following in the browser.
- Install the php_mysqli package as the sudoer user with the following command:
dnf install -y php-mysqli
Create the mysqli_check.php file in the /var/www/html directory as the root user:
<html> <header> <title>Static Query Object Sample</title> </header> <body> <?php if (!function_exists('mysqli_init') && !extension_loaded('mysqli')) { print 'mysqli not installed.'; } else { print 'mysqli installed.'; } if (!function_exists('pdo_init') && !extension_loaded('pdo')) { print '<p>pdo not installed.</p>'; } else { print '<p>pdo installed.</p>'; } ?> </script> </body> </html>
apache restart
Then, you can launch the Firefox browser and type the following:
localhost/mysqli_check.php
It should print the following in the browser.
mysqli installed. pdo installed.
- Check if the mod_ssl module is installed. You can use the following command::
rpm -qa | grep mod_ssl
Assuming it’s not installed, you install it like this:
dnf install -y mod_ssl
Recheck after installing mod_ssl with the following command::
rpm -qa | grep mod_ssl
It should print:
mod_ssl-2.4.51-7.el9_0.x86_64
- AlmaLinux and Apache require you to resolve the ServerName values and the public and private keys. Run this command on AlmaLinux to begin verifying and configuring the ServerName values and the public and private keys:
httpd -M | grep ssl
Assuming a new installation consistent with were MySQL and Apache were just configured, you should get the following message:
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message ssl_module (shared)
Recheck the failure for more detail with this command:
sudo systemctl status httpd.service -l --no-pager
It should print:
● httpd.service - The Apache HTTP Server Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; vendor preset: disabled) Drop-In: /usr/lib/systemd/system/httpd.service.d └─php-fpm.conf Active: active (running) since Sun 2022-11-13 22:39:07 EST; 1h 37min ago Docs: man:httpd.service(8) Main PID: 1351 (httpd) Status: "Total requests: 0; Idle/Busy workers 100/0;Requests/sec: 0; Bytes served/sec: 0 B/sec" Tasks: 213 (limit: 23280) Memory: 43.1M CPU: 2.733s CGroup: /system.slice/httpd.service ├─1351 /usr/sbin/httpd -DFOREGROUND ├─1443 /usr/sbin/httpd -DFOREGROUND ├─1452 /usr/sbin/httpd -DFOREGROUND ├─1456 /usr/sbin/httpd -DFOREGROUND └─1459 /usr/sbin/httpd -DFOREGROUND Nov 13 22:39:06 localhost.localdomain systemd[1]: Starting The Apache HTTP Server...

Nov 13 22:39:07 localhost.localdomain httpd[1351]: Server configured, listening on: port 80
It takes the next set of steps to fix the ServerName values.
- Generically, on Linux you need to find the files to modify. You can use the following command from within the /etc directory to find the configuration files in the /etc directory that include ServerName in them. Their values will be proceeded by a # symbol because they’re comments by default.
find /etc -type f | xargs grep -i ServerName
It should return the following:
./httpd/conf.d/ssl.conf:#ServerName www.example.com:443 ./httpd/conf/httpd.conf:# ServerName gives the name and port that the server uses to identify itself. ./httpd/conf/httpd.conf:#ServerName www.example.com:80 ./dnsmasq.conf:# tftp_servername (the third option to dhcp-boot) and in that
- Add the following line to the ssl.conf file as the root user:
ServerName localhost:443
- Add the following line to the httpd.conf file as the root user:
ServerName localhost:443
- After adding the two values, restart Apache with the following command:
sudo apachectl restart
- Rerun the systemctl command to get the status of the httpd service with this command:
sudo systemctl status httpd.service -l --no-pager
It should print:

- Generically, on Linux you need to find the files to modify. You can use the following command from within the /etc directory to find the configuration files in the /etc directory that include ServerName in them. Their values will be proceeded by a # symbol because they’re comments by default.
- Your next step requires setting up an SSL Certificate. Consistent with the design to build a standalone test system that uses a DHCP assigned IP address to resolve a localhost server name, you require the following two tasks to create an openssl self-signed certificate.
- On the new instance, you create a private subdirectory with this command:
sudo mkdir /etc/ssl/private
- Then, you can build a self-signed certificate with this command:
sudo openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /etc/ssl/private/apache-selfsigned.key -out /etc/ssl/certs/apache-selfsigned.crt
The openssl command will prompt you for these values to create a private key:
You are about to be asked to enter information that will be incorporated into your certificate request. What you are about to enter is what is called a Distinguished Name or a DN. There are quite a few fields but you can leave some blank For some fields there will be a default value, If you enter '.', the field will be left blank. ----- Country Name (2 letter code) [XX]: State or Province Name (full name) []: Locality Name (eg, city) [Default City]: Organization Name (eg, company) [Default Company Ltd]: Organizational Unit Name (eg, section) []: Common Name (eg, your name or your server's hostname) []: Email Address []:
- On the new instance, you create a private subdirectory with this command:
- Your last step requires three tasks to configure Apache to use SSL.
- You need to create the following sites-available directory with the following command as the root user:
mkdir /etc/httpd/sites-available
- Add the following localhost.conf/etc/httpd/sites-available directory:
<VirtualHost *:443> ServerName localhost DocumentRoot /var/www/html SSLEngine on SSLCertificateFile /etc/ssl/certs/localhost.crt SSLCertificateKeyFile /etc/ssl/private/apache-selfsigned.key </VirtualHost>
- Restart Apache with the following command:
sudo apachectl restart
- You need to create the following sites-available directory with the following command as the root user:
- After configuring everything, let’s test our self-signed HTTPS skunkworks. Launch the default Firefox browser and enter the following URL, which uses the mysql_check.php file from step #7:
https://localhost/mysqli_check.php
It will raise a warning message about a potential security risk, which is caused by our self-signed certificate. Click the Advanced… button and will see the option to Accept the Risk and Continue. If you want to use the self-signed and contained AlmaLinux LAMP stack for developer testing, accept the risk.
Having assumed the risk, the confirmation of the configuration will be displayed as follows:
As always, I hope this helps those looking to install MySQL, PHP, on AlmaLinux.
AlmaLinux MySQL+Python
After installing and configuring MySQL 8.0.30, I installed the Python connector. During that process on AlmaLinux, there were several changes since I last installed the Python’s mysql module. Here are the step-by-step instructions after installing and configuring MySQL Server (blog for those steps).
Using the MySQL Connector/Python X DevAPI Reference, you must install the pip utility before you install the library. You install the pip library as a sudoer user with the following command:
sudo yum install -y pip |
Then, using the pip utility as a sudoer user install the mysql-connector-python module with the following command:
sudo pip install mysql-connector-python |
Please note that this type of library installation can cause problems when you maintain multiple testing environments. If you plan to maintain multiple testing environments, please install this library in a virtual environment.
You create a bare-bones Python connection test program, like connect.py below:
# Import the library. import mysql.connector from mysql.connector import errorcode try: # Open connection. cnx = mysql.connector.connect(user='student', password='student', host='127.0.0.1', database='studentdb') # Print the value. print("Database connection resolved.") # Handle exception and close connection. except mysql.connector.Error as e: if e.errno == errorcode.ER_ACCESS_DENIED_ERROR: print("Something is wrong with your user name or password") elif e.errno == errorcode.ER_BAD_DB_ERROR: print("Database does not exist") else: print(e) # Close the connection when the try block completes. else: cnx.close() |
You test the connect.py program with this command:
python connect.py |
It’ll return the following provided you provisioned the student user and studentdb database:
Database connection resolved. |
If you’d like to run it without calling the python executable, you can add the following as the first line:
#/usr/bin/python |
and, change the default file permissions from
-rw-rw-r--. 1 student student 717 Oct 30 13:57 connect.py |
with the chmod command to
-rwxr-xr-x. 1 student student 717 Oct 30 13:57 connect.py |
These instructions should set you up to develop Python code against your AlmaLinux MySQL studentdb database. You use this syntax, assuming a default $PATH environment variable that excludes the present working directory.
./connect.py |
As always, I hope this helps those trying to get a complete solution.
