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 ]
