MariaDB Removal and MySQL Install

Evening,

We are using RHEL 7.0 which comes with MariaDB.. Unfortunately we have support with MySQL so I needed to install that instead. I was getting conflicts with libraries from MariaDB I am assuming.. so I think I attempted to remove MariaDB by doing this

 yum remove mariadb-libs-1:5.5.41-2.el7_0.x86_64

then I proceeded to install the "enterprise" version of MySQL. which seems to have been successful. however I can start it up by running mysqld_safe & and its find.. but when I try to use the startup script init.d/MySQL start I get a Starting MySQL. ERROR! The server quit without updating PID file (/data01/db/uhmc-msql-v1d.pid) so I just wonder if I removed the MariaDB properly so that wouldn't be a source of my issues.. I am very much a Linux newb so I might have easily missed something dumb.
