How to Upgrade MariaDB 5.5 to 10.0 on Fedora

Are you considering migrating from MariaDB 5.5 to the more robust and feature-rich MariaDB 10.0 on Fedora? This guide will walk you through the process step-by-step, ensuring a smooth transition and minimizing downtime.

Step 1: Check Current MariaDB Version

Before proceeding, it's essential to verify your current MariaDB version. Open your terminal and execute the following command:

$ rpm -qa | grep -i ^maria

This command will provide you with a list of MariaDB-related packages currently installed on your system. The expected results should look like this:

MariaDB-common-10.0.12-1
MariaDB-client-10.0.12-1
MariaDB-server-5.5.38-1
MariaDB-shared-10.0.12-1

If MariaDB Server 5.5 is still listed, proceed to the next steps to upgrade it.

Step 2: Stop Server and Backup Data

Before removing the existing MariaDB server, it's crucial to stop the service and back up your data. Use the following command to stop the MariaDB server:

$ systemctl stop mariadb

Once the server is stopped, proceed to back up your databases to ensure no data is lost during the upgrade process.

Note: Ensure you back up critical data before proceeding.

Step 3: Remove MariaDB Server

The next step is to remove the existing MariaDB 5.5 server. Use the following command to uninstall MariaDB:

$ yum remove MariaDB-server

After the uninstallation process, you may need to remove any residual configuration files (optional but recommended).

Step 4: Reinstall MariaDB 10.0

Now, it's time to reinstall the latest version of MariaDB. Use the following command to install MariaDB 10.0:

$ yum install MariaDB-server

After initiating the installation, you might see a confirmation prompt asking if you want to proceed. To confirm, simply press the Enter key:

Is this ok [y/N]: y

Once confirmed, the installation process will commence. You'll need to wait for the download and installation to complete.

Note: The installation process might take some time, depending on your internet speed and the system's performance.

Step 5: Verify Successful Upgrade

Finally, verify that the upgrade was successful by checking the MariaDB version again:

$ rpm -qa | grep -i ^maria

The successful upgrade or installation should result in the following output:

MariaDB-common-10.0.12-1
MariaDB-client-10.0.12-1
MariaDB-server-10.0.12-1
MariaDB-shared-10.0.12-1
