Apache2、mariadb 和 nginx 服务关闭

问：

每次我打开 apache2 或 mariadb 服务时，我都会得到： 无法连接到 MySQL localhost 错误 2002 （HY000）：无法通过套接字“/run/mysqld/mysqld.sock”连接到本地 MySQL 服务器 （2） 并关闭

service mysql restart

Job for mysql.service failed because the control process exited with error code.
See "systemctl status mysql.service" and "journalctl -xe" for details.


root:/home/admin# systemctl status mysql.service

然后我试了

systemctl status mariadb.service

可以使ubuntu服务器正常打开此服务的修复程序
