mysql service is now known as mariadb.
Try using "service mariadb start"

MariaDB is a fork of the original MySQL database.

From our point of view, only the package name is changed. MariaDB is still MySQL, and all the mysql command line utilities are still exactly named the same including the command called mysql.

The above message is incorrect, CentOS 6 still ships mysql.

Do you have the latest mysql-server package installed? What does rpm -q mysql-server output?

That tail -f only displayed the last 10 lines. Please provide the full output.
