In this tutorial we’ll upgrade/install to Mariadb 10.3 on Centos 7 running Vesta CP, by default vesta cp will install old base version of Mariadb 5.5 when installing on Centos 7. This tutorial will also work without vestacp installed i.e. on CWP, Cpanel. 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.
This tutorial will also work with CWP, cpanel.
Step 1 Remove MariaDB 5.5/10.0/10.1/10.2
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 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 :
service mysql stop yum remove MariaDB-server MariaDB-client
At this point MariaDB 10.0/10.1/10.2 will be removed completely but the databases are not removed don’t need to worry.
Then Install MariaDB 10.3 :
Step 2 Installation/Updating from MariaDB 5.5/10.0/10.1/10.2 to MariaDB 10.3
Install/enable Official repo for mariadb 10.3:
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 nano /etc/yum.repos.d/mariadb.repo
then paste this lines and save it :
[mariadb] name = MariaDB baseurl = http://yum.mariadb.org/10.3/centos7-amd64 gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB gpgcheck=1
After that we’ll install Mariadb 10.3
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 mysql service mysql start
Step 3
After that we need to upgrade current databases by this command :
mysql_upgrade
that’s it you’ve successfully upgraded MariaDB 5.5/10.0/10.1/10.2 to MariaDB 10.3.
You can confirm the version by running this command from terminal ssh:
mysql
