MySQL 5.5 关闭数据库报错

[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!

报错原因：
数据库之前使用过其他的socket

解决方法：
关闭数据库命令参数中，指定现有的socket名字

查看现有的socket
[root@localhost ~]# ps -ef|grep mysql
