解决
mysql登陆时出现“ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysql/mysql.sock' (2)”
?
mariadb同样适用
?
首先检查mysql状态
?
linux-6yo1:~ # /etc/init.d/mysql status
Checking for service MySQL: unused
mysql.service - LSB: Start the MySQL database server
Loaded: loaded (/etc/init.d/mysql)
Active: inactive (dead)
CGroup: name=systemd:/system/mysql.service

Jul 17 15:30:38 linux-6yo1.site systemd[1]: Stopped LSB: Start the MySQL dat....
?
?
发现Active: inactive (dead)
?
重启mysql.
?
linux-6yo1:~ # /etc/init.d/mysql restart redirecting to systemctl restart mysql
?
再次查看mysql状态
?
linux-6yo1:~ # ps aux | grep mysql root 5227 0.5 0.1 3204 1320 ? S 15:39 0:00 /bin/sh /usr/bin/mysqld_safe --mysqld=mysqld --user=mysql --pid-file=/var/run/mysql/mysqld.pid --socket=/var/run/mysql/mysql.sock --datadir=/var/lib/mysql mysql 5575 2.2 4.6 472456 47808 ?
