CentOS - Install MariaDB 5.5

CentOS does not come with MySQL in the repositories. Instead it has switched over to MariaDB. The script below will install MariaDB 5.5 which is extremely similar to MySql 5.5.

sudo yum install mariadb-server -y
sudo systemctl start mariadb
sudo systemctl enable mariadb
mysql_secure_installation

Now you can log into your database by entering the mysql command as usual.
