今天在连接客户服务器时MySQL的时候报:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql/mysql.sock’ (2)

[root@XXX ~]# mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can’t connect to local MySQL server through socket ‘/tmp/mysql/mysql.sock’ (2)

解决方案:

在登录MySQL数据库的时候用一下命令

mysql -h 127.0.0.1 -uroot -p

[root@XXX ~]# mysql -h 127.0.0.1 -uroot -p
Enter password:
