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。

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.

检查my.conf (/etc/mysql/my.cnf)，看看bind-address是否设置为127.0.0.1。
如果不是，这可能会导致此问题。
我不得不说:
sudo /etc/init.d/mysqld start
如果您的安装是最近的，您应该确认您的安装是否是安装服务器…mysql -服务器- 5.5 . .可能你只安装了“mysql”..这只是客户端而不是服务器。
试试这个:
mysql -h 127.0.0.1 -P 3306 -u root -p <database>
另外(看看它是否在运行):
telnet 127.0.0.1 3306
可能只是my.cnf文件中的错误配置，在/etc/某处(取决于Linux发行版)。
您应该验证/var/run/mysqld.的组的所有者如果不是mysql。Mysql，然后做:
su root
chown mysql.mysql /var/run/mysqld
