**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  
root      2487  2462  0 08:13 ?        00:00:00 /bin/sh /software/bin/mysqld\_safe --defaults-file=/mysql\_data/cnf/my.cnf  
mysql     3057  2487  0 08:14 ?        00:00:00 /software/bin/mysqld --defaults-file=/mysql\_data/cnf/my.cnf --basedir=/software --datadir=/mysql\_data/70005 --plugin-dir=/software/lib/plugin --user=mysql --log-error=/mysql\_log/err.log --open-files-limit=10240 --pid-file=/mysql\_data/70005/mysqld.pid --socket=/mysql\_data/70005/mysql.sock --port=55057  
root      3092  3026  0 08:14 pts/1    00:00:00 grep mysql  
  
\[root@localhost ~\]\# /software/bin/mysqladmin -?|grep sock  
  --protocol=name     The protocol to use for connection (tcp, socket, pipe,  
  -S, --socket=name   The socket file to use for connection.  
socket                            /cluster\_data/mysql.sock  
  
正常关闭数据库  
\[root@localhost ~\]\# /software/bin/mysqladmin -usystem -p'system' shutdown --socket=//mysql\_data/70005/mysql.sock
