1、登录Ubuntu系统，打开终端，进入python3虚拟环境djangotestworkon djangotest
3、创建应用app，取名为bookpython manage.py startapp book实际也是创建了一个文件夹book,里面文件可以用tree命令查看
5、创建book应用的视图，即在应用的viewspy定义函数，views.py代码如下from django.shortcuts import renderfrom django.http import HttpResponsedef index(request): return HttpResponse('hello world')注意函数第一个参数必须是request
7、在工程djapp的urls.py定义到book应用的路由，代码如下from django.conf.urls import url,includefrom django.contrib import adminimport book.urlsurlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^book/', include('book.urls')),]
9、打开本机输入网址http://127.0.0.1:8000/book/index就可以看hello world的页面啦
