在安裝django的時候，出現錯誤：

connect: _mysql_exceptions.OperationalError??: (2002, "Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)");

客戶端在連線服務端的時候，需要找到mysql.sock

解決應用程式呼叫mysql的找不到mysql.sock的問題

新的MT系統，我使用了mysql系統，一直用的很好，不過今天我偶然去使用phpmyadmin時，居然報Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'的錯誤。奇怪，明明mysql正常啟動，但為什麼phpmyadmin不能正常連線mysql，然後又直接去linux機器，本地執行mysql命令，發現mysql確實正常執行起來，

當出些類似Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'的錯誤時，解決方法：

1.mysql可能沒正常啟動，檢查mysql程式
2.修改/etc/my.cnf 修改mysql.sock的位置，使之滿足php或者cgi程式的需要
3.修改php.ini的mysql.sock的設定，滿足所有php程式的需要
4.修改某些程式中配置檔案中關於mysql.sock的設定。

 我得益於這篇文章，

Problem ¶

I want to use turbo gears, but my machine is setup with mysql not bound to a network socket and I get the following errors when I try to connect: _mysql_exceptions.

Solution ¶

There is a practice of not binding MySQL to an ip address and port following the principle that "if you're not connected, you are protected." In this situation, the server has a socket file. By default TurboGears (or SQLObject and the python MySQL driver/client to be more exact) will look for the socket file in /tmp/mysql.sock. Many installations seem to use /var/lib/mysql/mysql.sock. Therefore, to get TurboGears to work, you'll need to specify the unix_socket (if on unix) param in the dburi. You can find out where your mysql socket is by looking at the file my.cnf that usually resides in /etc/my.cnf or /etc/mysql/my.cnf.

Format: sqlobject.dburi="mysql://username:password@/databasename?unix_socket=path-to-mysql.sock"

Example: I have my socket file in /var/lib/mysql/mysql.sock and I want my user foo with password bar to connect to my db test1. sqlobject.dburi="mysql:/foo:bar@/test1?unix_socket=/var/lib/mysql/mysql.sock"
