Install MySQL 8.0 on Fedora Linux via MySQL RPM

Step 1: Update Fedora Before MySQL 8.0 Installation

Before installing MySQL 8.0, it’s essential to update your Fedora system. This step is vital to avoid compatibility issues and ensure your operating system functions at its best. To update Fedora, use the dnf package manager.

The following command not only checks for available updates but also installs them:

sudo dnf upgrade --refresh

The --refresh flag is essential as it forces dnf to refresh the repository metadata. This means it ensures your system checks against the most current version of packages available, rather than relying on possibly outdated information.

Step 2: Import the Official MySQL 8.0 Community Edition RPM

To install the latest version of MySQL 8.0 Community Edition on Fedora, start by importing the official RPM package.

Copy and paste the following code into your terminal:

sudo tee /etc/yum.repos.d/mysql-8.0.repo<<'EOF'
# MySQL Fedora repository list
name = MySQL
baseurl =$releasever/$basearch

The command varies based on your Fedora version.

Step 3: Install MySQL 8.0 Community Server

With the repository set up, proceed to install MySQL 8.0 Community Server:

sudo dnf install mysql-community-server

Step 4: Confirm MySQL Installation

Post-installation, ensure MySQL 8.0 is correctly installed:

mysql --version

This command displays the installed version of MySQL, verifying the successful completion of the installation.

Step 5: Activate MySQL 8.0

Lastly, activate MySQL 8.0 to ensure it’s operational:

sudo systemctl enable mysqld --now

Executing this command starts MySQL immediately and configures it to automatically launch at system start-up, guaranteeing its availability for immediate use and after reboots.

MySQL System Commands Examples with Fedora Linux

Checking the Status of MySQL Service

After installing MySQL 8.0 on Fedora, it’s vital to ensure the MySQL server runs correctly. By default, the service is inactive and not enabled on system start-up.

This can be fixed quickly with the following command:

sudo systemctl enable mysqld --now

Now, run the following command to verify the MySQL service is ok:

systemctl status mysqld
MySQL 8.0 systemd status showing 'service OK' on Fedora Linux
MySQL 8.0 Running Smoothly with Systemd on Fedora

This command provides information about the MySQL service’s current status, including operational status, error messages, or warnings, if any.

Managing the MySQL Service

Stopping the MySQL Service

In specific scenarios, you might need to stop the MySQL service manually. This could be for maintenance purposes or configuration changes. To stop the MySQL service, execute:

sudo systemctl stop mysqld

Starting the MySQL Service

To start the MySQL service, perhaps after a manual stop or maintenance, use this command:

sudo systemctl start mysqld

Disabling Automatic Start-up of MySQL

If you prefer that MySQL does not start automatically when the system boots, you can disable this feature. This might be desirable in a development environment or if you manage system resources closely. Use the following command to disable it:

sudo systemctl disable mysqld

Enabling Automatic Start-up of MySQL

Conversely, if you want MySQL to start automatically with your system’s boot process, enable this feature using:

sudo systemctl enable mysqld

This command is handy for ensuring database availability in production environments.

Restarting the MySQL Service

Sometimes, you may need to restart the MySQL service, especially after configuration changes or updates. To do this, execute:

sudo systemctl restart mysqld

Restarting the service can also help resolve temporary issues without affecting the overall system’s performance. This command stops and then starts the MySQL service in one action.

Secure MySQL 8 with a security script on Fedora Linux

Step 1: Launch MySQL Security Script

When MySQL 8.0 is installed in Fedora, its default settings may not align with stringent security standards. This gap can leave the system vulnerable to unauthorized access. To enhance the security of your MySQL installation, use the mysql_secure_installation script. This script strengthens MySQL by modifying less secure default options.

Start the security script with this command:

sudo mysql_secure_installation

This initiates a series of prompts to secure your MySQL installation.

Step 2: Handling the Root Password

Initially, MySQL’s root password should be unset. If, for any reason, it’s been set and you don’t have it, you can find the temporary password in the MySQL logs. Retrieve it using:

sudo grep 'temporary password' /var/log/mysqld.log

This command searches the MySQL log file for the temporary password assigned during installation.

Step 3: Configure Security Settings

The security script guides you through various steps to fortify your MySQL setup:

  1. Setting Root Password: Establish a strong root password if one is not already set or if you wish to change it.
  2. Securing User Accounts: Assess and secure other MySQL user accounts, ensuring they have strong passwords.
  3. Limiting Root Access: Remove remote root account access, restricting root privileges to local host connections.
  4. Removing Anonymous Accounts: Delete anonymous user accounts that don’t have a username, as they can be a significant security risk.
  5. Eliminating Test Database: The test database, accessible to anonymous users by default, should be removed to prevent unauthorized access to test tables.

The script will prompt you with questions for each step. Enter “Y” to confirm the changes and enhance your MySQL installation’s security. If necessary, you can also reset the root password during this process by following the script’s prompts to create a new one.

[joshua@fedora ~]$ mysql_secure_installation

Securing the MySQL server deployment.

Enter password for user root: 

The existing password for the user account root has expired. Please set a new password.

New password: <---- SET NEW PASSWORD

Re-enter new password: <---- RE-ENTER NEW PASSWORD

Re-enter new password: 
The 'validate_password' component is installed on the server.
The subsequent steps will run with the existing configuration
of the component.

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

Remove anonymous users? (Press y|Y for Yes, any other key for No) : Y <---- Type Y then press the ENTER KEY.

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 <---- Type Y then press the ENTER KEY.

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

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : Y <---- Type Y then press the ENTER KEY.
 - Dropping test database...

 - Removing privileges on test database...

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 <---- Type Y then press the ENTER KEY.

All done!
