错误例如以下：

Timeout error occurred trying to stop MySQL Daemon.

Stopping mysqld:                                           [FAILED]

Starting mysqld:                                           [  OK 
]

解决的方法：

[root@AY140624215512103ccdZ

local]#

Solution (force kill mysqld - warning you do risk table corruption here but there's no choice if you want your DB up right away)

[root@AY140624215512103ccdZ local]# killall -9 mysqld

[root@AY140624215512103ccdZ local]# service mysqld restart
