    sh: mysql_config: 未找到命令
    Traceback (most recent call last):

      File "/tmp/pip-install-p9LTrB/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

2、MySQL-python包依赖mysql-devel包，需首先安装mysql-devel包

yum -y install mysql-devel

3、安装完成mysql-devel包，再次安装MySQL-python包成功
