MySQL 5.5 關閉資料庫報錯"Can't connect to local MySQL server through socket"

MySQL 5.5 關閉資料庫報錯

[root@localhost ~]# /software/bin/mysqladmin -usystem -p'system' shutdown
/software/bin/mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/cluster_data/mysql.sock' (2)'
Check that mysqld is running and that the socket: '/cluster_data/mysql.sock' exists!

報錯原因：
資料庫之前使用過其他的socket

解決方法：
關閉資料庫命令引數中，指定現有的socket名字

檢視現有的socket
[root@localhost ~]# ps -ef|grep mysql
