MySQL doesn't start up.

After querying the log is ' Fatal Error:can ' t open and Lock Privilege tables:table ' mysql.host ' doesn ' t exist ' this error (Less/var/log/mysqld.log)

Try to remove all of the MySQL clean, generally delete dirty (after deletion of residual configuration file my.cnf) The total removal method is as follows

[Email protected] lib]# Rpm-qa¦grep mysqlmysql-5.5.25-1.el6.remi.i686mysql-libs-5.5.25-1.el6.remi.i686compat-mysql51-5.1.54-1.el6.remi.i686mysql-server-5.5.2 5-1.el6.remi.i686[[email protected] lib]# yum remove MySQL mysql-server mysql-libs compat-mysql51 (delete all)
This is completely unloaded, and then reloading will get a new MySQL.

Or not?
