MariaDB is a drop-in replacement for MySQL installed by default on CentOS 7, and offers many speed and performance improvements. MariaDB offers more storage engines than MySQL, including Cassandra (NoSQL), XtraDB (drop-in replacement for InnoDB), and OQGRAPH.
- These instructions are intended for upgrading from MariaDB 5.5 to MariaDB 10.0 on CentOS 7.
- I’ll be working from a Liquid Web Core Managed CentOS 7 server, and I’ll be logged in as root.
First, you’ll follow a simple best practice: ensuring the list of available packages is up to date before installing anything new:
yum -y update
Now find which repo you should use with the MariaDB repository generator. We’re going to add the CentOS 7 (64 bit) MariaDB 10.0 repository.

name = MariaDB
baseurl = http://yum.mariadb.org/10.0/centos7-amd64
Then exit and save the file with the command
systemctl stop mariadb
Remove the existing MariaDB packages:
yum remove mariadb-server mariadb mariadb-libs
Clean-up the repository cache information with the following command:
yum clean all
At this point, installing MariaDB 10.0 is as simple as running just one command:
yum -y install MariaDB-server MariaDB-client
And then start MariaDB again:
systemctl start mysql
Be sure that MariaDB is set to start at boot:
systemctl enable mysql
Verify MySQL is now MariaDB by using the command client:
Your MariaDB connection id is 4
