MariaDB is designed as a drop-in replacement of MySQL with more features, new storage engines, fewer bugs, and better performance. MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Foundation and the MariaDB Corporation, and by many people in the community.
To upgrade follow these simple steps to upgrade it to the latest version:
Step 1: Remove MariaDB 5.5/10.0/10.1/10.2/10.3
Before installing it is recommended to backup your databases, although it is not necessary if you followed these steps carefully.
First backup your current my.cnf config:
cp /etc/my.cnf /etc/my.cnf.bak
For MariaDB 5.5:
service mariadb stop / service mysql stop rpm -e --nodeps galera yum remove mariadb mariadb-server
At this point, MariaDB 5.5 will be removed completely but the databases are not removed don’t need to worry.
For MariaDB 10.0/10.1/10.2/10.3:
service mysql stop rpm -e --nodeps galera yum remove MariaDB-server MariaDB-client
At this point, MariaDB 10.0/10.1/10.2/10.3 will be removed completely but the databases are not removed don’t need to worry.
Then Install MariaDB 10.4.
