問題描述

我在 LAMPwiki/List_of_Ubuntu_releases#Ubuntu_12.04_LTS_.28Precise_Pangolin.29">Ubuntu 12.04 LTS (Precise Pangolin) 然后在 phpMyAdmin.我忘記了密碼，現在無法登錄.當我嘗試通過終端更改密碼時，我得到:

I installed LAMP on Ubuntu 12.04 LTS (Precise Pangolin) and then set root password on phpMyAdmin. I forgot the password and now I am unable to login. When I try to change password through terminal I get:

ERROR 2002 (HY000): 無法通過套接字連接到本地 MySQL 服務器'/var/run/mysqld/mysqld.sock'(2)

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

我該如何解決這個問題?我無法打開 LAMP、卸載或重新安裝.

How can I fix this? I am unable to open LAMP, uninstall it or reinstall it.

推薦答案

我曾經遇到過這個問題，通過安裝mysql-server解決了，所以請確認你已經安裝了mysql-server，而不是 mysql-client 或其他東西.

I once had this problem and solved it by installing mysql-server, so make sure that you have installed the mysql-server, not the mysql-client or something else.

那個錯誤意味著文件/var/run/mysqld/mysqld.sock不存在，如果你沒有安裝mysql-server，那么文件不會存在.所以在這種情況下，用

That error means the file /var/run/mysqld/mysqld.sock doesn't exists, if you didn't install mysql-server, then the file would not exist. So in that case, install it with

sudo apt-get install mysql-server

但是如果mysql-server已經安裝并且正在運行，那么你需要檢查配置文件.

But if the mysql-server is already installed and is running, then you need to check the config files.

配置文件是:

/etc/my.cnf
/etc/mysql/my.cnf
/var/lib/mysql/my.cnf

在/etc/my.cnf中，socket文件配置可能是/tmp/mysql.sock和/etc/mysql/my.cnf 套接字文件配置可能是 /var/run/mysqld/mysqld.sock.所以，刪除或重命名/etc/mysql/my.cnf，讓mysql使用/etc/my.cnf，那么問題就可以解決了.

In /etc/my.cnf, the socket file config may be /tmp/mysql.sock and in /etc/mysql/my.cnf the socket file config may be /var/run/mysqld/mysqld.sock. So, remove or rename /etc/mysql/my.cnf, let mysql use /etc/my.cnf, then the problem may solved.
