If you made any changes to /etc/my.cnf you will want to change those back.

You might want to empty /var/log/mysqld.log and delete 
/var/log/mysqld.log.*

D       elete /var/run/mysqld/mysqld.pid (as long as mysqld is not 
running).

If you are concerned about .mysql_history, check for it in other home 
directories too.

Run "rpm -V mysql-server" to see if other changes were made.

Consider disabling mysqld from starting.

Aside from my.cnf, the configuration is in the databases, which is built 
at boot time.
