1.MySQLdb下載地址：

https://pypi.python.org/pypi/MySQL-python/1.2.5

2. unzip MySQL-python-1.2.5；

3. cd MySQL-python-1.2.5;

  python setup.py install;

此時報錯：

Traceback (most recent call last):
  File "setup.py", line 17, in <module>
    metadata, options = get_config()
  File "/root/MySQL-python-1.2.5/setup_posix.py", line 43, in get_config
    libs = mysql_config("libs_r")
  File "/root/MySQL-python-1.2.5/setup_posix.py", line 25, in mysql_config
    raise EnvironmentError("%s not found" % (mysql_config.path,))
EnvironmentError: mysql_config not found

原因是沒有安裝mysql-devel;

yum install mysql-devel;

4.重新執行python setup.py install；

此時報錯：

unable to execute gcc: No such file or directory
error: command 'gcc' failed with exit status 1

安裝gcc就可以了: yum install gcc;

5.再次執行python setup.py install；

fatal error: Python.h: No such file or directory

 #include "Python.h"
                    ^
compilation terminated.
error: command 'gcc' failed with exit status 1

注意：有很多資料說要下載python-dev，說的是centos6，

centos7上是下載不來的；

6.執行 python setup.py install;

至此MySQLdb安裝成功了。
