## 导语
> 在Centos7下，当前python版本是2.7.5，测试实时获取日志然后解析入库中，安装`MySQL-python`模块报错如
`EnvironmentError: mysql_config not found`，原因是缺少了 mysql 相关支持。
> 这里把解决过程记录一下

环境信息
系统： Centos7.2
Python 版本： 2.7.5
---
具体报错信息：
```
root@pts/4 $ pip install MySQL-python
Collecting MySQL-python
Using cached MySQL-python-1.2.5.zip
Complete output from command python setup.py egg_info:
sh: mysql_config: command not found
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/tmp/pip-build-kWowP9/MySQL-python/setup.py", line 17, in <module>
metadata, options = get_config()
File "setup_posix.py", line 43, in get_config
libs = mysql_config("libs_r")
File "setup_posix.py", line 25, in mysql_config
raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found
----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-build-kWowP9/MySQL-python/
```

mysql_config是来自于 `mysql-devel` ，我用的是MySQL社区版，所以实际安装的是`mysql-community-devel`，网上的说法是同时安装`python-devel`，如果你没有安装的话一起安装
yum install python-devel mysql-community-devel -y
安装完成之后尝试再次 pip 安装 MySQL-python
---
## 再次安装
```
root@pts/4 $ pip install MySQL-python
Collecting MySQL-python
Using cached MySQL-python-1.2.5.zip
Installing collected packages: MySQL-python
Running setup.py install for MySQL-python ... done
Successfully installed MySQL-python-1.2.5
