Yum cannot install MySQL

Last night to help friends set up a server, has been a yum MySQL   can not install. The error message is as follows:

Transaction Check Error:
File/etc/my.cnf from install of mysql-libs-5.1.66-2.el6_3.x86_64 conflicts with file from package lunamp-1.1.9-beta2.x86 _64

The reason: The library package in MySQL that comes with Linux conflicts with the  library in yum install MySQL.

The solution is as follows:

Delete the MySQL library that comes with Linux.

Yum Remove  lunamp-1.1.9-beta2.x86_64

Can.
