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

    2 directories, 17 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：
