mysql数据库提示ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)

①无提示无法通过/var/lib/mysql/mysql.sock连接数据库；

[root@proeim mysql]# mysql -uxxx -pxxx -Dxxx -A

ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2

②排查发现是因为该目录下缺少mysql.sock文件；

③通过软连接的形式来复制得到相关文件：

cd /var/lib/mysql/

ln -s /tmp/mysql.sock  mysql.sock

④查看mysql的状态：

service mysqld-ib status

MySQL is not running, but lock exists [FAILED]

⑤然后启动mysql：

[root@proeim bin]# service mysqld-ib start

Starting MySQL.. [ OK ]

 

⑥然后连接mysql，发现连接成功了：

 

mysql -uxxx -pxxx -Dxxx -A
