MYSQL dead but pid file exists問題

伺服器突然斷電，造成MySQL資料庫啟動不了的問題，現象如下：
[[email protected] html]# service mysql51-mysqld start kill 31011: No such process Another MySQL daemon already running with the same unix socket. Starting mysql51-mysqld: [FAILED] [[email protected] html]# service mysql51-mysqld status mysql51-mysqld dead but pid file exists
本想找pid檔案刪除，後來找不到這個檔案，於是刪除mysql.sock檔案後啟動也可以：
[[email protected] html]# mv /var/lib/mysql/mysql.sock /var/lib/mysql/mysql.sock.back
[[email protected] html]# service mysql51-mysqld start
kill 31011: No such process
Starting mysql51-mysqld: [ OK ]
