环境

linux 7.0

python 2.7.5

问题

执行Python脚本，发生报错如下

ImportError: No module named MySQLdb

得知须安装【MySQL-python】模块

遂下载编译安装MySQL-python-1.2.5.zip，发生如下报错

EnvironmentError: mysql_config not found

而后，被各种依赖整疯，好容易装完MySQL-python-1.2.5.zip，取出已编译安装包，在新机器上测试，可离线安装。

解决

文件：/usr/lib64/python2.7/site-packages/MySQL_python-1.2.5-py2.7-linux-x86_64.egg

1、查看现有系统是否有安装数据库，若已安装mysql，请从4开始执行

rpm -qa | grep mysql 

mysql-community-server-5.7.20-1.el7.x86_64
mysql-community-libs-compat-5.7.20-1.el7.x86_64
mysql-community-libs-5.7.20-1.el7.x86_64
mysql-community-client-5.7.20-1.el7.x86_64
mysql-community-devel-5.7.20-1.el7.x86_64
mysql-community-common-5.7.20-1.el7.x86_64

2、若有mariadb-libs-5.5.56-2.el7.x86_64，使用rpm卸载 

rpm -qa | grep mariadb 

rpm -e mariadb-libs-1:5.5.56-2.el7.x86_64 --nodeps

3、安装Mysql

请按如下顺序安装，否则会报错
rpm -ivh mysql-community-common-5.7.20-1.el7.x86_64.rpm       
rpm -ivh mysql-community-libs-5.7.20-1.el7.x86_64.rpm            
rpm -ivh mysql-community-devel-5.7.20-1.el7.x86_64.rpm        
rpm -ivh mysql-community-libs-compat-5.7.20-1.el7.x86_64.rpm  
rpm -ivh mysql-community-client-5.7.20-1.el7.x86_64.rpm  
rpm -ivh mysql-community-server-5.7.20-1.el7.x86_64.rpm  

4、将文件放在该目录下【MySQL_python-1.2.5-py2.7-linux-x86_64.egg】

/usr/lib64/python2.7/site-packages/

5、执行该语句

echo MySQL_python-1.2.5-py2.7-linux-x86_64.egg > /usr/lib64/python2.7/site-packages/pythonmysql.pth
