在Python安装MySQLdb模块遇见的问题

安装python2.7的MySQLdb模块时遇见如下问题：
[root@mycat-1 MySQL-python-1.2.3b1]# python setup.py build
running build
running build_py
copying MySQLdb/release.py -> build/lib.linux-x86_64-2.7/MySQLdb

#include “my_config.h”
^

看网上说要安装mysql-devel：

yum install -y mysql-devel

但是安装之后还是报同样的错误
执行:which mysql_config

[root@mycat-1 MySQL-python-1.2.3b1]# which mysql_config/home/mycat/mysql_5717/bin/mysql_config

我感觉我发现问题了，可能是我yum安装mysql-devel、mysql的版本与PATH路径下的mysql_config版本有冲突
修改PATH中mysql_config路径，改外/usr/bin/mysql_conifg之后，再进行安装，成功了。
tips：还可以通过修改setup_posix.py中mysql_config.path直接改为/usr/local/mysql_config来解决版本冲突问题。
