Centos6.7下安装python连接mysql环境故障解决

在Python连接和使用mysql时，需要调用MySQLdb 模块，是用于Python链接Mysql数据库的接口，它实现了 Python 数据库 API 规范 V2.0，基于 MySQL C API 上建立的。
MySQLdb模块在不同的平台下安装方式不一样，这里主要介绍Linux下的安装方式，https://pypi.python.org/pypi/MySQL-python 可以在这里选择合适的版本，解压安装。
安装步骤：

1、选择合适的版本以及检查相关路径
这里选择版本为MySQL-python-1.2.5.zip，下面是下载路径与过程。
wget https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip --2016-10-08 21:34:56--  https://pypi.python.org/packages/a5/e9/51b544da85a36a68debe7a7091f068d802fc515a3a202652828c73453cad/MySQL-python-1.2.5.zip Resolving pypi.python.org... 151.101.76.223, 2a04:4e42:12::223

[root@localhost python]# ls

切换到解压目录安装：
使用命令 python  setup.py  build && python  setup.py install

安装报错：

[root@localhost MySQL-python-1.2.5]# python  setup.py  build
Traceback (most recent call last):
File "setup.py", line 7, in <module>
import setuptools
ImportError: No module named setuptools
提示缺少setuptools 可以在

安装命令和上面一样，等最后执行完毕没有报错，安装成功，我们继续安装上面的。
python  setup.py   build
running build
running build_py

。。。。。。

[root@localhost setuptools-0.6c11]# cd  ..

继续安装MySQL-python 出现error: command 'gcc' failed with exit status 1可以用以下命令解决

yum install gcc python-devel mysql-devel libxml2 libxml2-dev libxslt* zlib gcc openssl

安装完成后的检验：
在shell窗口调用Python命令，然后执行，不报错即可

import MySQLdb
