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

今天登陆mysql出现这个问题

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

搞了半天是因为mysql没有启动

输入

sudo service mysql start

如果安装的是MariaDB 则输入

sudo service mariadb start

启动mysql

然后 mysql -u root -p 就ok了。
