我收到了这个错误

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

尽管我已经设法在 ubuntu 中通过命令行启动了 mysql

mysql stop/waiting
mysql start/running, process 17691

但是，当我尝试访问该站点时，我得到一个数据库连接错误以及尝试通过 mysql -u root -p

我检查了我的错误日志并看到了这个

这是我第一次看到这个错误，我不知道如何解决这个问题，请在这里帮帮我。

谢谢

好的，我尝试了glglgl的解决方案，重新启动后，我在错误日志中得到以下信息:

最佳答案

检查进程是否在 Ubuntu 12.04 上运行，我的问题已解决

ps ax | grep mysql

然后答案是它没有运行，所以我运行了

sudo service mysql start

或者试试

sudo /etc/init.d/mysql start
