Can't connect to local MySQL server through socket 问题解决办法

参考 https://tableplus.com/blog/2018/08/solved-cant-connect-to-local-mysql-server-through-socket.html

错误消息为：

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

症状，是msyql 命令可以通过root@127.0.0.1登录到msyql服务器，但是无法通过root@localhost登录

解决办法，修改msyql的配置文件，/etc/my.cnf

[mysqld]

socket=/var/lib/mysql/mysql.sock 

[client]

socket=/var/lib/mysql/mysql.sock

重启msyqld服务。
