我在Ubuntu 12.04 LTS (Precise穿山甲)上安装了LAMP，然后在phpMyAdmin上设置根密码。我忘记密码了，现在无法登录。当我试图通过终端更改密码时，我得到:
错误2002 (HY000):无法通过套接字连接到本地MySQL服务器 ' / var /运行/ mysqld / mysqld。袜子”(2)
我该如何解决这个问题?我无法打开LAMP，卸载它或重新安装它。
当前回答
对我来说是:
打开/etc/mysql/my.cnf或/etc/my.cnf，搜索“bind-address”。结果是127.0.0.1。我将其转换为localhost，因此行结果应该是'bind-address = localhost'。
否则，你应该使用bind-address指令中存在的IP地址运行你的MySQL服务器，即MySQL -h 127.0.0.1。
其他回答
mysqld stop
mysql.server start
我用重启mysql解决了这个问题
/etc/init.d/mysql stop
and
/etc/init.d/mysql start
就是这样。
对我来说，在CentOS上，我不得不像这样重新启动mariadb服务:
systemctl start mariadb.service
在我的案例中，这只是因为mysql停止了，因为/etc/mysql/my.cnf中定义的/var/log/mysql文件夹丢失了创建后，我可以启动mysql，它像往常一样运行。
This error can also occur if you try to change the directory where the database is stored, but imput the wrong directory in the configuration file (like a typo in the second drive as D instead of the accurate D_). Instead of telling you the typo directory does not exist, it will tell you that you lack permission to access it (leading you to try to change the permissions for the typo directory, which it will let you do). So if you get this error while changing directories, double check the configuration file and make sure you don't have a typo.
