If you do not already have a supported version of mysql installed on your Centos 7 or Redhat Enterprise Linux 7 system, follow these instructions to install mysql.  If you are using Centos 6 or Redhat Enterprise Linux 6 do not follow these instructions.  Use the instructions at this link instead.

Step 1: Login as root

Log into the system as the root user.

Step 2: Install software

As the root user, run this command:

yum install mariadb-server

Step 3: Set the mysql server to start on boot

As the root user, run this command:

systemctl enable mariadb

Step 4: start the mysqld service

As the root user, run this command:

systemctl start mariadb

Step 5: Harden the mysqld server

As the root user, run this command:

mysql_secure_installation

Note: This will ask you to change the MySQL root password, remove anonymous user accounts, disable root logins outside of localhost, and remove test databases. It is recommended that you answer yes to these options.
