MySQL on Ubuntu

without comments

Fresh install of Ubuntu on my MacBook Pro i7 because Apple said the OS X was no longer upgradable. Time to install and configure MySQL Server. These are the steps to install MySQL on the Ubuntu Desktop.

Installation

  1. Update the Ubuntu OS by checking for, inspecting, and upgrading any available updates with the following commands:

    sudo apt update
    sudo apt list
    sudo apt upgrade
  2. Check for available MySQL Server packages with this command:

    apt-cache search binaries | grep -i mysql

    It should return:

    mysql-server - MySQL database server binaries and system database setup
    mysql-server-8.0 - MySQL database server binaries and system database setup
    mysql-server-core-8.0 - MySQL database server binaries
    default-mysql-server - MySQL database server binaries and system database setup (metapackage)
    default-mysql-server-core - MySQL database server binaries (metapackage)
    mariadb-server-10.6 - MariaDB database core server binaries
    mariadb-server-core-10.6 - MariaDB database core server files
  3. Check for more details on the MySQL packages with this command:

    apt info -a mysql-server-8.0
  4. Install MySQL Server packages with this command:

    sudo apt install mysql-server-8.0
  5. Start the MySQL Server service with this command:

    sudo systemctl start mysql.service
  6. Before you can run the mysql_secure_installation script, you must set the root password. If you skip this step the mysql_secure_installation script will enter an infinite loop and lock your terminal session. Log in to the mysql monitor with the following command:

    sudo mysql

    Enter a password with the following command (password is an insecure example):

    ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'C4nGet1n!';

    Quit the mysql monitor session:

    quit;
  7. Run the mysql_secure_installation script with this command:

    sudo mysql_secure_installation

    Here’s the typical output from running the mysql_secure_installation script:

    Securing the MySQL server deployment.
     
    Enter password for user root: 
     
    VALIDATE PASSWORD COMPONENT can be used to test passwords
    and improve security. It checks the strength of password
    and allows the users to set only those passwords which are
    secure enough. Would you like to setup VALIDATE PASSWORD component?
     
    Press y|Y for Yes, any other key for No: Y
     
    There are three levels of password validation policy:
     
    LOW    Length >= 8
    MEDIUM Length >= 8, numeric, mixed case, and special characters
    STRONG Length >= 8, numeric, mixed case, special characters and dictionary file
     
    Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 2
    Using existing password for root.
     
    Estimated strength of the password: 100 
    Change the password for root ? ((Press y|Y for Yes, any other key for No) : N
     
     ... skipping.
    By default, a MySQL installation has an anonymous user,
    allowing anyone to log into MySQL without having to have
    a user account created for them. This is intended only for
    testing, and to make the installation go a bit smoother.
    You should remove them before moving into a production
    environment.
     
    Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y
    Success.
     
    Normally, root should only be allowed to connect from
    'localhost'. This ensures that someone cannot guess at
    the root password from the network.
     
    Disallow root login remotely? (Press y|Y for Yes, any other key for No) : Y
    Success.
     
    By default, MySQL comes with a database named 'test' that
    anyone can access. This is also intended only for testing,
    and should be removed before moving into a production
    environment.
     
     
    Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y
     - Dropping test database...
    Success.
     
     - Removing privileges on test database...
    Success.
     
    Reloading the privilege tables will ensure that all changes
    made so far will take effect immediately.
     
    Reload privilege tables now? (Press y|Y for Yes, any other key for No) : Y
    Success.
     
    All done!

Configuration

The next step is configuration. It requires setting up the sample sakila and studentdb database. The syntax has changed from prior releases. Here are the new three steps:

  1. Grant the root user the privilege to grant to others, which root does not have by default. You use the following syntax as the MySQL root user:

    mysql> GRANT ALL ON *.* TO 'root'@'localhost';
  2. Download the sakila database, which you can download from this site. Click on the sakila database’s TGZ download.

    When you download the sakila zip file it creates a sakila-db folder in the /home/student/Downloads directory. Copy the sakila-db folder into the /home/student/Data/sakila directory. Then, change to the /home/student/Data/sakila/sakila-db directory, connect to mysql as the root user, and run the following command:

    mysql> SOURCE /home/student/Data/sakila/sakila-db/sakila-schema.sql
    mysql> SOURCE /home/student/Data/sakila/sakila-db/sakila-data.sql
  3. Create the studentdb database with the following command as the MySQL root user:

    mysql> CREATE DATABASE studentdb;
  4. Create the user with a clear English password and grant the user student full privileges on the sakila and studentdb databases:

    mysql> CREATE USER 'student'@'localhost' IDENTIFIED WITH mysql_native_password BY 'Stud3nt!';
    mysql> GRANT ALL ON studentdb.* TO 'student'@'localhost';
    mysql> GRANT ALL ON sakila.* TO 'student'@'localhost';

You can now connect to a sandboxed sakila database with the student user’s credentials, like:

mysql -ustudent -p -Dsakila

or, you can now connect to a sandboxed studentdb database with the student user’s credentials, like:

mysql -ustudent -p -Dstudentdb

MySQL Workbench Installation

sudo snap install mysql-workbench-community

You have now configure the MySQL Server 8.0.
