Question

所以我一直在使用MySQL的rails服务器，突然无法访问我的数据库。当我尝试使用mysql -u root -p登录时，我得到ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)。我已经阅读了我能找到的大多数论坛，并查看了所有尝试重置mysqld.sock的日志。我尝试重新安装和重新包装失败。奇怪的是重新安装后var / run / mysqld /甚至不存在。

所以我决定只备份我的数据库并检查所有内容。我用apt-get remove --purge清除了apache和mysql并重新安装。一切顺利，apache启动正常，然后尝试用systemctl start mysql重启mysql，提示检查日志说：

更新 - 我创建了文件夹mysqld，它似乎允许sudo mysqld --initialize运行。不幸的是，这产生了错误 2016-12-17T00:16:36.298825Z 0 [ERROR] Can't change data directory owner to mysql 2016-12-17T00:16:36.299212Z 0 [ERROR] Aborting

所以还没有派对。任何想法都会非常感激。

修改/etc/mysql/conf.d/mysql.cnf：

sudo nano /etc/mysql/conf.d/mysql.cnf

添加此行： socket=/var/run/mysqld/mysqld.sock

然后重启mysql服务：

sudo service mysql restart

Mysql错误ERROR 2002（HY000）在完全重新安装后仍然存在
