Starting MySQL.Manager of pid-file quit without updating fi

自己的CentOS 5.5 上的mysql登录不了，报出了下面的错误，

Starting MySQL…Manager of pid-file quit without updating

解决方案：

杀掉已经启动的进程

[root@localhost ~]# ps -A|grep mysql

17590 pts/5    00:00:00 mysqld_safe

17693 pts/5    00:00:00 mysqld

kill掉他们！！

kill -9 17590 

kill -9 17693 

[root@localhost ~]# /etc/init.d/mysql restart

MySQL manager or server PID file could not be found! [FAILED]

Starting MySQL [ OK ]
