Install Ruby on Fedora
I use a Fedora 20 VM image to teach Oracle and MySQL technology. Last week, I expanded the Fedora VM image to support a full LAMP stack. This blog shows you how to install Ruby on Fedora and successfully generate the Rails gems.
Connect as the root user and use yum to install the libraries. My approach is by library or small groups. Naturally, you start with the ruby library.
yum install ruby |
You will see the following:

After installing ruby, exit the root account to your management account and run the following command from the Linux shell:
ruby -v |
It should show you:

Before you can run gem to install rails, you must install another the libxml2-devel library. Here’s the syntax to install the libxml2-devel library:

One more to go. You can’t run the Ruby gem utility to create the nokogiri Ruby Gem on Fedora because of a library mismatch. If you attempt to create the Rails framework, like this:
gem install rails |
It’ll raise the following error message on trying to dynamically link the nokogiri Ruby Gem. The error will be something like this, and unfortunately, the log files won’t be too useful:
Running patch with /usr/local/share/gems/gems/nokogiri-1.6.6.2/ports/patches/libxml2/0001-Revert-Missing-initialization-for-the-catalog-module.patch... Running 'patch' for libxml2 2.9.2... ERROR, review '/usr/local/share/gems/gems/nokogiri-1.6.6.2/ext/nokogiri/tmp/x86_64-redhat-linux-gnu/ports/libxml2/2.9.2/patch.log' to see what happened. *** extconf.rb failed *** Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options. |
The error message isn’t very helpful but the fix is fortunately easy. You install the nokogiri Ruby Gem directly with the yum utility. The following instructs yum to proceed without waiting for you to type a y to install.
yum install -y rubygem-nokogiri |

Now you can use the Ruby gem utility to create the Rails framework like this:

If you want to install Phusion Passenger, mod_passenger is already installed. You should note that support and testing for this stops at Fedora V17. You can verify installation with the following command:
yum list mod_passenger |
It returns:
Loaded plugins: langpacks, refresh-packagekit
Available Packages
mod_passenger.x86_64 4.0.53-3.fc20.2 updates |
You can also install the Ruby Gem for Passenger, like this:
gem install passenger |
It should take less than 2 minutes and return something like this:

As always, I hope this was helpful. I’ll add a post with the remaining MySQL and Oracle connection details soon.
MySQL bind-address
While I try to keep things simple, sometimes eliminating options and explanations comes back to haunt me. After posting how to open a Fedora firewall port for a LAMP stack, somebody got trapped by my instructions for installing MySQL on Fedora. They got stuck because they had the following setting in their /etc/my.cnf file:
bind-address=localhost.localdomain |
I’d suggested using that bind-address value for a DHCP VMware Fedora installation in Step #7. I was trying to create an example for an isolated testing instance, which is why I set the bind-address to a localhost.localdomain value. They raised the following error when they tried to connect their base operating system’s version of MySQL Workstation to the Fedora VM:
Failed to Connect to MySQL at 192.168.2.168:3306 with user student |
or, this dialog image:
Before you do the next step, please ensure you’re using the right IP address. You can find that by running this command as an authorized sudoer:
ifconfig | grep inet.*netmask.*broadcast |
In this case, the command returns:
inet 192.168.2.168 netmask 255.255.255.0 broadcast 192.168.2.255 |
I’ve since added instructions to the older post to set the bind-address value in the my.cnf file as follows when they want to support external connections (naturally that means authorizing port 3306):
bind-address=0.0.0.0 |
After you reset the /etc/my.cnf file, you must stop and start, or restart the mysqld service. You can do that as the root user like this:
systemctl restart mysqld |
Then, you can test a student user connection from MySQL Workbench like this:
If the student user is authorized and the password is correct, you’ll see that the connection now works:
As always, I hope this helps those working through similar issues.
Open Fedora Port 80
After installing the LAMP stack on Fedora, you need to open port 80 in the Firewall to access the PHP programs on the Fedora instance from external servers. You can open a firewall port by launching the firewall-config application as the root user with the following syntax:
firewall-config |
The firewall-config utility opens the following dialog:
Click on the Ports tab, and you’ll see the following:
Skip this step if you only want to set the runtime privilege to the port. Click on the Runtime tab and change it to Permanent if you want the port to be accessible when you reboot your OS.
Click on Add button to add a port exception, and you’ll see the following:
Enter Port 80 for the Apache server unless you used a different value for the Apache server’s listener port. If you’re not sure open the /etc/httpd/conf/httpd.conf file and check for the following line (default value shown):
Listen 80 |
Click the OK button to set the port exception. Then, you can connect to the Linux machine with the IP address, a DNS name, or a name you resolve in your local hosts file, like:
http://192.168.2.1/query.php |
You can find the IP address of your Fedora image by inspecting the /etc/hosts file or capture a DHCP assigned address with the following command as the root user (or with sudo as a valid sudoer user):
ifconfig -a |
It should return the following image, which is based on the data stored in MySQL’s studentdb database, as qualified in yesterday’s blog post:
I hope this helps those setting up a LAMP instance to work with the MySQL database.
Fedora Install LAMP
My students wanted an extra credit assignment, so I thought a LAMP configuration and test would be appropriate. The only problem was I hadn’t added it to their course VMware instance. So, here are the instructions to install Apache2, PHP, and MySQLi for a complete LAMP stack when MySQL is already installed.
The post builds on my Fedora Install of MySQL and MySQL Workbench on Fedora posts from last year. It also presumes that you’ve installed a studentdb database but you need to know how to do that let me know (but it hasn’t changed much from the example at the bottom of this old MySQL 5.1 blog post).
You install Apache2 with the following command as the root user, or with the sudo command as a sudoer-list user:
yum install httpd |
The following displays the results of starting the yum utility to install httpd, and you need to reply with a y to complete the installation:

After installing the software, you can set the Apache server to start automatically with the following command:
chkconfig httpd on |
However, that command only starts the Apache server the next time you boot the server. You use the following command as the root user to start the Apache server:
apachectl start |
You can verify the installation with the following command as the root user:
ps -ef | grep httpd | grep -v grep |
It should return:
root 5433 1 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5434 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5435 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5436 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5437 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5438 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND apache 5442 5433 0 17:03 ? 00:00:00 /usr/sbin/httpd -DFOREGROUND |
and, then verify the listening port with the following command as the root user:
netstat -tulpn | grep :80 |
It should return the following when both the Apache server is listening on port 80 and the Oracle multi-protocol server is listening on port 8080:
tcp6 0 0 :::80 :::* LISTEN 5433/httpd tcp6 0 0 :::8080 :::* LISTEN 1505/tnslsnr |
After verifying the connection, you can test it by creating the traditional info.php program file in the /var/www/http directory. The file should contain the following:
1 2 3 | <?php phpinfo(); ?> |
You can test it by opening the Firefox browser and entering the following URL from the Fedora Linux image:
http://localhost/info.php |
It should display the typical diagnostic page. This verifies the configuration of the Apache and PHP servers. The next step verifies whether you have the mysqli library to connect to the MySQL database.
You create a mysqli_check.php script, like this:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 | <html>

You can test it with the following URL from the local browser:

If it’s installed you can skip the next step, but if not you need to run yum in expert mode as follows (the check for php-mysql isn’t really necessary because it’s too old a version but good practice):

You should note that this also installed PDO. One caveat, before you rerun the mysqli_check.php script from a browser, you need to restart the Apache server. You can do that as the root user with the following syntax:
apachectl restart |
You can retest it with the following URL from the local browser:
http://localhost/mysqli_check.php |
At this point you should have everything installed to test your connection the MySQL database. As mentioned, this example extends my instructions for installing MySQL on the Fedora instance.
The following query.php file tests your ability to connect to the MySQL database with the mysqli driver, and it uses the studentdb and video store example from my Oracle Database 11g and MySQL 5.6 Developer Handbook:

This should display the following in the browser:
You can see how to open port 80 for the Apache server in this blog post. If you want to work with blob data types, you’ll also need to use yum to install the php-gd library. You can read my LAMP php-gd library blog post to learn how to install the libraries. As always, I hope a step-by-step approach without assumptions helps those learning MySQL.
Add Color to VIM?
In Fedora 20, documents have no color coding when you edit them with vi or vim. That’s because Fedora installs vim-minimal by default. You can check what’s running with the following command at a shell prompt in the terminal:
rpm -qa | grep vim |
It should print the following to console:
vim-minimal-7.4.179-1.fc20.x86_64 |
You can download and install vim with the enhanced version by using the following syntax:
sudo yum install vim-enhanced |

You can now type vim to edit files in color but vi will still be in black and white.
Wrapping SQL*Plus
One annoying thing from installing Oracle Database 11g on Fedora, was that the up arrows for command history didn’t work. I decided to fix that today after seeing Lutz Hartmann’s article on rlwrap. Unfortunately, the epel (Extra Packages for Enterprise Linux) package he recommended doesn’t run on Fedora 20. You can read my tale of woe, or skip to the .bashrc function that fixed it when I installed only rlwrap.
Attempting it on yum, gave me these errors:
# yum install http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm Loaded plugins: langpacks, refresh-packagekit epel-release-6-8.noarch.rpm | 14 kB 00:00 Examining /var/tmp/yum-root-5CLTPa/epel-release-6-8.noarch.rpm: epel-release-6-8.noarch Marking /var/tmp/yum-root-5CLTPa/epel-release-6-8.noarch.rpm to be installed Resolving Dependencies --> Running transaction check ---> Package epel-release.noarch 0:6-8 will be installed --> Processing Conflict: epel-release-6-8.noarch conflicts fedora-release No package matched to upgrade: epel-release --> Finished Dependency Resolution Error: epel-release conflicts with fedora-release-20-3.noarch You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles –nodigest |
Poking around for an epel fix wasn’t successful, so I chose to install only the rlwrap package. Here’s that command and log file:
[root@localhost ~]# yum install rlwrap Loaded plugins: langpacks, protectbase, refresh-packagekit 0 packages excluded due to repository protections Resolving Dependencies --> Running transaction check ---> Package rlwrap.x86_64 0:0.41-1.fc20 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: rlwrap x86_64 0.41-1.fc20 updates 95 k Transaction Summary ================================================================================ Install 1 Package Total download size: 95 k Installed size: 204 k Is this ok [y/d/N]: y Downloading packages: rlwrap-0.41-1.fc20.x86_64.rpm | 95 kB 00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction (shutdown inhibited) Installing : rlwrap-0.41-1.fc20.x86_64 1/1 Verifying : rlwrap-0.41-1.fc20.x86_64 1/1 Installed: rlwrap.x86_64 0:0.41-1.fc20 Complete! |
The next step was getting it to work. A sqlplus function wrapper inside the .bashrc file seemed the easiest. Here’s the code to the .bashrc file:
# .bashrc # Source global definitions if [ -f /etc/bashrc ]; then . /etc/bashrc fi # Uncomment the following line if you don't like systemctl's auto-paging feature: # export SYSTEMD_PAGER= # User specific aliases and functions . /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh # Wrap sqlplus with rlwrap to edit prior lines. sqlplus() { if [ "$RLWRAP" = "0" ]; then sqlplus "$@" else rlwrap sqlplus "$@" fi } # Set vi as a command line editor. set -o vi |
As always, I hope this helps some folks.
Fedora VMWare Upgrade
When a new update of VMWare comes out, and it is time to upgrade VMWare Tools. Here’s an update on the instructions for upgrading VMWare Tools 6.0.1 through 6.0.4:
- Navigate to the VMWare Menu, choose Virtual Machine and in the drop down menu Install VMWare Tools. This will mount a virtual CD in the Oracle Unbreakable Linux virtual machine and it launches the following dialog box:
- Open a terminal session by right clicking anywhere in the desktop, and then choose Open in Terminal from the context menu. You can then run the VMWare Toolkit by following these instructions as the
rootuser:
The instructions for VMWare 6.0.0 through 6.0.2 are:
cd /media/VMware\ Tools cp VMwareTools-9.6.2-1688356.tar.gz /tmp cd /tmp gunzip VMwareTools-9.6.2-1688356.tar.gz tar -xvf VMwareTools-9.6.2-1688356.tar cd vmware-tools-distrib sudo ./vmware-install.pl |
VMWare changed where the VMWare Tools CD are mounted. You can discover it by clicking on the VMware Tools in the left pane (this assumes you log on to Fedora as the student user, and the student user is a sudo-enabled user)
The instructions for VMWare Tools 6.0.4 forward are listed below. Only the first command changes. You should also note that the VMWare Tools library is the same:
cd /run/media/student/VMware\ Tools cp VMwareTools-9.6.2-1688356.tar.gz /tmp cd /tmp gunzip VMwareTools-9.6.2-1688356.tar.gz tar -xvf VMwareTools-9.6.2-1688356.tar cd vmware-tools-distrib sudo ./vmware-install.pl |
The last step requires that you reply to a set of prompts. If you’d like to accept the default at one time, you can use the following command:
sudo ./vmware-install.pl --default |
Lastly, you’ll get these instructions form the Perl script that installs the VMWare tools:
The configuration of VMware Tools 9.6.2 build-1688356 for Linux for this running kernel completed successfully. You must restart your X session before any mouse or graphics changes take effect. You can now run VMware Tools by invoking "/usr/bin/vmware-toolbox-cmd" from the command line. To enable advanced X features (e.g., guest resolution fit, drag and drop, and file and text copy/paste), you will need to do one (or more) of the following: 1. Manually start /usr/bin/vmware-user 2. Log out and log back into your desktop session; and, 3. Restart your X session. Enjoy, --the VMware team |
A/UX, NeXTSTEP, & OS X
One thing that gets tedious in the IT community and Oracle community is the penchant for Windows only solutions. While Microsoft does an excellent job in certain domains, I remain a loyal Apple customer. By the way, you can install Oracle Client software on Mac OS X and run SQL Developer against any Oracle Database server. You can even run MySQL Workbench and MySQL server natively on the Mac OS X platform, which creates a robust development platform and gives you more testing options with the MySQL monitor (the client software).
Notwithstanding, some Windows users appear to malign Apple and the Mac OS X on compatibility, but they don’t understand that it’s a derivative of the Research Unix, through BSD (Berkeley Software Distribution). This Unix lineage chart illustrates it well:
I’m probably loyal to Apple because in the early 1990’s I worked on Mac OS 6, Mac OS 7, A/UX, NeXTSTEP, and AIX/6000 (Version 3) while working at APL (American President Lines) in Oakland, California. Back then, my desktop was a pricey Macintosh Quadra 950 and today I work on a pricey Mac Pro desktop. The Mac Pro lets me use VMware virtualize development environments for Oracle Linux, Red Hat Enterprise Linux, Fedora, and as you might guess Windows 7/8. My question to those dyed in the wool Microsoft users is simple, why would you choose a single user OS like Windows over a multi-user OS like Mac OS X?
Mac Mini to the rescue
In teaching, I had a problem because my students have different base operating systems, like Windows 7, Windows 8, Linux, and Mac OS X. I needed a teaching and lecture platform that would let me teach it all (not to mention support their environments). That meant it had to virtualize any of the following with a portable device:
- Windows 7 or 8 hosting natively an Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
- Windows 7 or 8 hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
- Mac OS X hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
- Ubuntu hosting a Fedora or Oracle Unbreakable Linux VM (3 or 4 GB) with Oracle Database 11g XE, 11g, or 12c and MySQL Database 5.6
I never considered a manufacturer other than Apple for a laptop since they adopted the Intel chip. Too many of the others sell non-hyperthreaded laptop machines that they market as i5 or i7 64-bit OS machines when they’re not. Some of those vendors disable the hyperthreading facility while others provide motherboards that can’t support hyperthreading. The ones I dislike the most provide a BIOS setting that gives the impression you can enable hyperthreading when you can’t. All Apple devices, MacBook, MacBook Pro, Mac Mini, and Mac Pro do fully support a 64-bit OS and their virtualization.
A MacBook Pro came to mind but the disk space requirements were 1 TB, and that’s too pricey. I went with the Mac Mini because with 16 GB of memory and a 1 TB drive it was only $1,200. Add a wireless keyboard and mighty mouse, and an HDMI and mini-DVI connections, and I had my solution. Naturally, my desktop is a one generation old Mac Pro with 64 GB of memory and 12 TB of disk space, which supports all the virtual machines used for testing. Note to Apple marketing staff: The prior version of the Mac Pro let you pay reasonable (3rd party) prices for the additional memory and disk drives.
The Mac Mini means I can travel anywhere and plug into the console and demo tools and techniques from a myriad set of platforms without the hassle of moving on and off to frequently VM images. It’s a great solution with only one downside, HDMI to DVI sometimes creates purple toned screens. It’s unfortunate because some venues have monitors that don’t support HDMI).
Open a port on Fedora
Since MySQL Workbench 6.0 isn’t available for Fedora, Version 20, I’m having my students install it on their local Windows and Mac OS X operating systems. You can configure the /etc/sysconfig/iptables file to enable port 3306 after installing MySQL on Fedora.
You can open a port by using the firewall-config utility (easy way) or by adding the following line to the /etc/sysconfig/iptables file (Fedora’s instructions on editing iptables [hard way]). The file won’t exist initially, but you can create it by running the following command as the root superuser or sudoer:
shell> service iptables save |
You you can run the following commands as the root superuser, which saves the line in the iptables file:
shell> iptables -A INPUT -m conntrack --ctstate NEW -m tcp -p tcp --dport 3306 -j ACCEPT shell> iptables-save |
After making the change to the /etc/iptables file you can change the firewall by running the following command as the root superuser:
shell> service iptables restart |
Just make sure you don’t inadvertently start both iptables and ip6tables as services. You can check that only one is running by using the following commands:
shell> service iptables status shell> service ip6tables status |
MySQL Workbench Configuration
- The first thing you need to do is click on the
+symbol in the circle to the right of the MySQL Connections text label. It launches the Setup New Connection dialog.
- The second thing you need to do is enter a Connection Name, Hostname, Port, and Username. Then, click the Test Connection button.
- The Test Connection button launches the Connect to MySQL Server dialog. Enter the password for the
studentuser (or whatever user you’re interested in), and then click the OK button.
- When the credentials in the Connect to MySQL Server dialog work, you see the following confirmation dialog message. Click the OK button to continue and you’ll see a new VMWare Fedora Instance connection icon.
- Click the VMWare Fedora Instance connection to start a new connection.
- The VMWare Fedora Instance button launches the Connect to MySQL Server dialog. Like you did when configuring the connection, enter the password for the
studentuser (or whatever user you’re interested in), and then click the OK button. It launches an interactive panel that lets you run, edit, or save the SQL script file.
- Type the following two lines in the Query1 panel (at least if you have a
studentdbdatabase:USE studentdb; SELECT DATABASE();
