Django-简单项目创建

1. 在磁盘中找到需要存放项目代驾的目录，进入该目录(本机为: /Downloads/All)
2. 输入Django创建项目命令：django-admin startproject mysite，此时在目录下会创建一个名为“mysite”的文件夹
3. 进入mysite文件夹，查看目录中文件清单

   1. mysite/
          manage.py
          mysite/
              __init__.py
              settings.py
              urls.py
              wsgi.py

4. 清单详解
   1. manage.py:命令行管理工具集，用于与Django项目的交互管理
   2. __init__.py:空文件，用于通知python这个目录是一个Python项目
   3. settings.py:设置和配制Django项目
   4. urls.py:内容分发器，用于配制Django中的站点
   5. wsgi.py:用于网关部署配制
5. 使用默认数据库sqlite3，创建数据库及表结构：python manage.py migrate

   1. ➜  mysite  python manage.py migrate
      Operations to perform:
        Synchronize unmigrated apps: staticfiles, messages
        Apply all migrations: admin, contenttypes, auth, sessions
      Synchronizing apps without migrations:
        Creating tables...
          Running deferred SQL...
        Installing custom SQL...
      Running migrations:
        Rendering model states... DONE
        Applying contenttypes.0001_initial... OK
        Applying auth.0001_initial... OK
        Applying admin.0001_initial... OK
        Applying contenttypes.0002_remove_content_type_name... OK
        Applying auth.0002_alter_permission_name_max_length... OK
        Applying auth.0003_alter_user_email_max_length... OK
        Applying auth.0004_alter_user_username_opts... OK
        Applying auth.0005_alter_user_last_login_null... OK
        Applying auth.0006_require_contenttypes_0002... OK
        Applying sessions.0001_initial... OK

6. 启动服务器：python manage.py runserver

   1. ➜  mysite  python manage.py runserver
      Performing system checks...
      
      System check identified no issues (0 silenced).

      Django version 1.8.6, using settings 'mysite.settings'
      Starting development server at http://127.0.0.1:8000/
      Quit the server with CONTROL-C.

7. 在浏览器中输入地址：http://127.0.0.1:8000/，若页面显示正确，则项目创建成功
   1. 修改启动端口：python manage.py runserver 8001
   2. 修改启动IP及端口：python manage.py runserver 0.0.0.0:8001
8. 至此，第一个简单的Django项目创建成功了
