python-Django中连接MySQL数据库及设置用户名密码

项目和应用创建好以后，进入当前的目录所在的文件夹即可操作，也可以用pycharm中的Tools工具运行manage.py，本人采用的是运行pycharm下的manage.py文件
配置：
1.把对应的应用添加到INSTALLED_APPS下，注意分号

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog', #应用
]
2.修改数据库连接

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', # 提示连接mysql数据库
        'NAME': 'test', # 数据库名为test，要自己创建
        'USER': 'root', # 用户名
        'PASSWORD': 'root',    # 密码
        'HOST': '127.0.0.1', # 连接的主机
        'PORT': '3306', # 对应的端口号
    }
}
3.运行：

manage.py@hello_mysite > migrate # 连接数据库
"D:\pycharm\PyCharm 5.0.3\bin\runnerw.exe" D:\python\python.exe "D:\pycharm\PyCharm 5.0.3\helpers\pycharm\django_manage.py" migrate G:/hello_mysite
