/django/mysite/learning_log/learning_log

INSTALLED_APPS = (
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
 
    'learning_log',

18.1.7 创建数据库

Django 将大部分与项目相关的信息都存储在数据库中,因此我们需要创建一个供Django使用的数据库

配置mysql数据库

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'tlcb',
'USER': 'root',
'PASSWORD': '1234567',
'HOST': '192.168.137.3',
'PORT': '3306',
}
}

node2:/django/mysite/learning_log#python manage.py migrate

18.1.8 创建应用:
django-admin.py startproject learning_log
