django与数据库的同步终于成功了！！mark一下

在安装django的时候，出现错误： connect: _mysql_exceptions.OperationalError??: (2002, Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)); 客户端在连接服务端的时候，需要找到mysql.sock 请看这篇文章 http://blog.5ilinux.c

解决应用程序调用mysql的找不到mysql.sock的问题

新的MT系统，我使用了mysql系统，一直用的很好，不过今天我偶然去使用phpmyadmin时，居然报Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'的错误。奇怪，明明mysql正常启动，但为什么phpmyadmin不能正常连接mysql，然后又直接去linux机器，本地运行mysql命令，发现mysql确实正常运行起来，看来是phpmyadmin的问题，马上去找phpmyadmin的配置文件，发现确实有设置mysql.sock文件的位置，由于安装MT的缘故，我把mysql.sock选择在/tmp/mysql.sock。修改之下，phpmyadmin正常运行，但随之我又发现我的另外一个blog系统wp也不能正常调用mysql，它也是一个php的blog，但这个程序确没地方设置mysql.sock的位置，左思右想发现php.ini有修改mysql.sock的设置，只要在这里设置了，所有的php应用就再也不报以上错误。通过以上调试总结出以下结论：

当出些类似Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock'的错误时，解决方法：

1.mysql可能没正常启动，检查mysql程序
2.修改/etc/my.cnf 修改mysql.sock的位置，使之满足php或者cgi程序的需要
3.修改php.ini的mysql.sock的设置，满足所有php程序的需要
4.修改某些程序中配置文件中关于mysql.sock的设置。

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

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"
