Django配置MySQL数据库

##更改配置

<project_name>/settings.py 一开始是使用sqlite3的，改成MySQL的就好

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'opencourse',
        'USER': 'opencourse',
        'PASSWORD': 'opencourse',
        'HOST': '172.25.254.10'
    }
}

安装驱动

*如果没有安装MySQL驱动的，就pip install MySQL-python 安装一个.如果出现错误，提示没有找到mysql_config的。
Ubuntu类的安装apt install libmysqlclient-dev,Redhat类yum install -y mysql-devel

在确保安装了libmysqlclient-dev或者mysql-devel的同学，如果使用pycharm的话，直接File->Settins->Project Interpreter点加号+ 搜索mysql,然后点击Install Package即可。

生成数据库表

python manage.py makemigrations,或者pycharm中，Tools->Run manage.py Task 直接输入makemigrations，然后migrate。

如下：

manage.py@opencourse > makemigrations
No changes detected
manage.py@opencourse > migrate
