一、创建blog应用：

    django-admin startapp blog

二、目录结构：

    aplex@aplex:~/website/mysite$ ls

    blog  manage.py  mysite

    aplex@aplex:~/website/mysite$ tree

    .

    ├── blog

    │   ├── admin.py

    │   ├── admin.pyc

    │   ├── __init__.py

    │   ├── __init__.pyc

    │   ├── models.py

    │   ├── models.pyc

    │   ├── tests.py

    │   ├── views.py

    │   └── views.pyc

    ├── manage.py

    └── mysite

        ├── __init__.py

        ├── __init__.pyc

        ├── settings.py

        ├── settings.pyc

        ├── urls.py

        ├── urls.pyc

        └── wsgi.py

     directories,  files

    aplex@aplex:~/website/mysite$ 

三、settings配置：

    aplex@aplex:~/website/mysite$ cat mysite/settings.py

    ......

    INSTALLED_APPS = (

        'django.contrib.admin',

        'django.contrib.auth',

        'django.contrib.contenttypes',

        'django.contrib.sessions',

        'django.contrib.messages',

        'django.contrib.staticfiles',

        'blog',

    )

    ......

四、urls配置：

    aplex@aplex:~/website/mysite$ cat mysite/urls.py

    from django.conf.urls import patterns, include, url

    from django.contrib import admin

    admin.autodiscover()

    urlpatterns = patterns('',

        # Examples:

        # url(r'^$', 'mysite.views.home', name='home'),

        # url(r'^blog/', include('blog.urls')),

        url(r'^admin/', include(admin.site.urls)),

        url(r'^blog/index/$', 'blog.views.index'),

    )

五、view:

    aplex@aplex:~/website/mysite$ cat blog/views.py

    from django.shortcuts import render

    from django.http import HttpResponse

    # Create your views here.

    def index(req):

        return HttpResponse('<h1>hello world</h1>')

    aplex@aplex:~/website/mysite$ 

六、效果：
