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.

你检查过LAMPP是否在运行吗?
sudo bash <path>/lampp start
对我来说,路径就是
sudo bash /opt/lampp/lampp start
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)。
我的服务器上的简单解决方案:在使用MySQL数据库迁移到新的Debian 7服务器后,第二个本地IP地址127.0.1.1在我的hosts文件中丢失了。添加这个解决了警告:
echo -e "\n127.0.1.1 $(hostname)" >> /etc/hosts

我现在遇到了这个问题,并且解决了它。
尽管您安装了mysql-server,但是需要运行守护进程才能使客户机连接到它。
首先检查mysql服务器是否正在运行:
netstat -tap | grep mysql
你应该会看到这样的东西:
$ sudo netstat -tap | grep mysql
tcp 0 0 localhost:mysql *:* LISTEN 6639/mysqld
如果您没有运行服务器,请使用以下命令启动守护进程:
/etc/init.d/mysql restart
如果已经安装,这应该可以解决您的问题。
