virtualenv 的作用相当于 Sandbox，它通过隔离包目录和系统环境参数来实现多个相对独立的虚拟环境。可避免过多的第三方库因为版本依赖造成问题。同时每个独立的虚拟环境只需通过打包即可分发，也大大方便了系统部署。(摘自互联网)

注意，在此环境下安装的软件仅在此环境下有效。

创建项目：

创建第一个项目myappdir1

[root@s26 www]# django-admin.py startproject myappdir1

[root@s26 www]# tree myappdir1

myappdir1

|-- __init__.py

|-- manage.py

|-- settings.py

`-- urls.py

0 directories, 4files

创建第二个项目myappdir2

[root@s26 www]# django-admin.py startproject myappdir2

[root@s26 www]# tree myappdir2

myappdir1

|-- __init__.py

|-- manage.py

|-- settings.py

`-- urls.py

0 directories, 4files

编写模块：

在第一个项目中添加hello_world.py

[root@s26 myappdir1]# vi hello_world.py

from django.http import HttpResponse

def hello_world(request):

return HttpResponse("Hello world--app1")

在第二个项目中添加hello_world2.py

[root@s26 myappdir2]# vi hello_world2.py

from django.http import HttpResponse

def hello_world2(request):

return HttpResponse("Hello world--app2")

设置应用：

在第一个项目的urls.py添加黑体字部分

[root@s26 myappdir1]# more urls.py

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

from myappdir1.hello_world import hello_world

# Uncomment the next two lines to enable the admin:

# from django.contrib import admin

# admin.autodiscover()

urlpatterns = patterns('',

# Examples:

# url(r'^$', 'myappdir1.views.home', name='home'),

# url(r'^myappdir1/', include('myappdir1.foo.urls')),

# Uncomment the admin/doc line below to enable admin documentation:

# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:

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

('^hello_world/$', hello_world),

)

在第二个项目的urls.py添加黑体字部分

[root@s26 myappdir2]# cat urls.py

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

from myappdir2.hello_world2 import hello_world2

# Uncomment the next two lines to enable the admin:

# from django.contrib import admin

# admin.autodiscover()

urlpatterns = patterns('',

# Examples:

# url(r'^$', 'myappdir2.views.home', name='home'),

# url(r'^myappdir2/', include('myappdir2.foo.urls')),

# Uncomment the admin/doc line below to enable admin documentation:

# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

# Uncomment the next line to enable the admin:

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

('^hello_world2/$', hello_world2),

)
