MySQLdb-python安装

安装很简单，步骤如下：

前期：yum -y install python-setuptools，或者自己网上找源码包安装

1. 下载安装包：

#wget  https://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.5.zip --no-check-certificate

#unzip  MySQL-python-1.2.5.zip

#cd MySQL-python-1.2.5

#python setup.py build

未成功安装测试时会提示：
>>> import mysqldb
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: No module named mysqldb

安装时遇到的错误：

若在执行python setup.py build时报错报EnvironmentError: mysql_config not found，需要进行如下操作：

1. 使用find / -name mysql_config查找mysql_config的位置，如/usr/bin/mysql/mysql_config

2. 修改MySQL-python-1.2.5 /site.cfg文件，去掉mysql_config=XXX注释,并改成mysql_config=/usr/bin/mysql/mysql_config

3. 如果没有mysql_config命令，则需要安装如下包：

yum -y install mysql-server mysql-devel mysql-shared
