Django2.2 pip安装Mysql模块mysql_config缺失问题

续上回安装完python和pip后就开始拉代码，执行数据库迁移
在执行迁移的时候出现以下错误:

django.core.exceptions.ImproperlyConfigured: Error loading MySQLdb module.

缺少了Mysql模块，pip安装即可
ps:最新安装的是mysqlclient 而非 pymysql

[root@vultr ~] pip install mysqlclient 

错误摘要如下:

OSError: mysql_config not found
   
    ----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-knr3eh_4/mysqlclient/

然而重点在mysql_config这里
解决方法是将mysql_config挂载/usr/local/bin/mysql_config

然而看了下 /usr/local/mysql/bin/ 根本没mysql_config这个文件
需要安装mysql-devel 安装完后会自动生成 （没该问题的自动跳到下一条）

[root@vultr ~]# yum install mysql-devel

挂载

 [root@vultr ~]# ln -s /usr/local/mysql/bin/mysql_config /usr/local/bin/mysql_config

重新安装mysqlclient

[root@vultr ~]# pip install mysqlclient
Collecting mysqlclient

Installing collected packages: mysqlclient
  Running setup.py install for mysqlclient ... done
Successfully installed mysqlclient-1.4.2.post1

最后记得到项目的 /yourProjectName/__init__.py加上一行

import MySQLdb
