How To Upgrade MariaDB on Centos 7?

To upgrade your MariaDB service, you need some requirements.


First, you must log in to your server as a non-root user with sudo privileges. To do this, you can follow our guide the Initial Server Setup with Centos 7.

Then, you must have a version of MariaDB that is not the latest version.

Now follow the steps below to complete this guide.

Step 1 – Check Current MariaDB Version on Centos 7

The first step is to check the current MariaDB version and Centos version using the below commands:

# mysql -V
mysql Ver 15.1 Distrib 5.5.68-MariaDB, for Linux (x86_64) using readline 5.1
cat /etc/centos-release
CentOS Linux release 7.9.2009 (Core)

Step 2 – Create Backup of Existing Databases

Then, you must create a backup or a dump of the existing databases. To do this, run the following command:

mysqldump -u root -p --all-databases > /tmp/database-backup.sql
Next, copy the database directory into a separate folder with the following command:
cp -a /var/lib/mysql /var/lib/mysql.backup
Now you must back up the configuration file with the following command:
cp -a /etc/my.cnf /etc/my.cnf_bk
Note: During the upgrading process, if you face issues, you can use one of the above copies to restore your databases.

Step 3- Uninstall Old MariaDB Repository on Centos 7

In this step, you need to uninstall the old MariaDB repositories. To do this, stop your MariaDB service on Centos 7 with the following command:
systemctl stop mariadb
