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

错误提示：

root@localhost ~]# mysql --socket=/tmp/mysql.sock
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

解决方法：

由于mysql 默认的mysql.sock 是在/var/lib/mysql/mysql.sock，但linux系统总是去/tmp/mysql.sock查找，所以会报错

[root@localhost ~]# find / -name mysql.sock
/var/lib/mysql/mysql.sock

 

1.直接指定mysql通道

 

[root@localhost ~]# mysql --socket=/var/lib/mysql/mysql.sock
Welcome to the MySQL monitor.  Commands end with ; or /g.
Your MySQL connection id is 2 to server version: 5.0.22

Type 'help;' or '/h' for help. Type '/c' to clear the buffer.

mysql>

 

2. 创建符号连接：

 

为mysql.sock增加软连接（相当于windows中的快捷方式）。

ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock

eg：
root@localhost ~]# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
[root@localhost ~]# ln -s /var/lib/mysql/mysql.sock /tmp/mysql.sock
[root@localhost ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or /g.
Your MySQL connection id is 3 to server version: 5.0.22

Type 'help;' or '/h' for help. Type '/c' to clear the buffer.

mysql>

我觉得这两个方法挺好用的
