Short description about MariaDB :
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 this simple steps to upgrade it to 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 this steps carefully.
First backup your current my.cnf config :
cp /etc/my.cnf /etc/my.cnf.bak
Now we need to remove current version of mariadb 5.5 installed on centos 7 :
For MariaDB 5.5 :
service mariadb stop / service mysql stop
rpm -e --nodeps galera
yum remove mariadb mariadb-server
t 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 :
Step 2 Installation/Updating from MariaDB 5.5/10.0/10.1/10.2/10.3 to MariaDB 10.4
Install/enable Official repo for mariadb 10.4:
yum install nano epel-release -y
Now edit/create the Repo file :
Ensure you don’t have any other MariaDB repo file in
/etc/yum.repos.d if exists delete or backup the existing repo file :
mv /etc/yum.repos.d/mariadb.repo /etc/yum.repos.d/mariadb.repo.bak
then paste this lines and save it :
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos7-amd64
After that we’ll install Mariadb 10.4
yum clean all
yum install MariaDB-server MariaDB-client net-snmp perl-DBD-MySQL -y
yum update -y
Restore the my.cnf file :
rm -rf /etc/my.cnf
cp /etc/my.cnf.bak /etc/my.cnf
Then enable mariadb to start on boot and start the service :
systemctl enable mariadb
service mysql start
After Installation we need to upgrade current databases by this command :
