CentOS7使用pip安装mysql-python出错解决方案

具体错误：

[root@localhost liuyuantao]# pip install mysql-python
Collecting mysql-python

EnvironmentError: mysql_config not found

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-7Pn8K6/mysql-python/

上面的错误是由于缺少mysql_config文件导致，查看下mysql_config文件是否存在

[root@localhost liuyuantao]# find / -name mysql_config
find: ‘/proc/5155’: No such file or directory
find: ‘/run/user/1000/gvfs’: Permission denied

果然mysql_config没有找到，是因为缺少mysql-devel，导致mysql_config丢失，安装mysql-devel即可。

yum install mysql-devel

若提示错误应该是MySQL的源存在问题，安装MySQL的源即可，具体见CentOS7编译安装MySQL5.7之后安装mysql-devel出错解决方案

mysql-devel安装成功之后，查看mysql_config是否存在

[root@localhost liuyuantao]# find / -name mysql_config
find: ‘/run/user/1000/gvfs’: Permission denied
/usr/bin/mysql_config

在/usr/bin/mysql_config已经存在，使用pip安装mysql-python即可

root@localhost liuyuantao]# pip install mysql-python

接下来我们就可以使用python操作MySQL数据库了
