Can't connect to local MySQL server through socket'/tmp/mysql.sock'

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

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 / -namemysql.sock

/var/lib/mysql/mysql.sock

把/var/lib/mysql/mysql.sock添加到/etc/my.cnf
