2) for Windows, you need to download git from the Internet.

3) Ubuntu users can: $ sudo apt-Get install Git-core

4) after installing git, clone it from GitHub.

 
$ Git clone https://Github.com/django/django
 

5) switch to the directory

 
$ CD Django
 

6) Installation

 
$ Python setup. py install
 

7) test whether Django is successfully installed.

3. Start Hello World

1) Select a directory to store the Django project and switch to the directory.

 
$ Sudo mkdir djangoworkspace $ CD djangoworkspace
 

2) create a project myblog

 
$ Django-admin.py startproject myblog
 

After the creation is successful, a mange. py and myblog folder will be generated under the myblog file. The directory structure is as follows:

 
Myblog-Myblog-_ Init _. py-Settings. py-URLs. py-Wsgi. py-Manage. py
 

If you are prompted that the django-admin.py command cannot be found, you needAdd% Python PATH %/scripts to environment variable path.

3) start the project

 
Python manage. py runserver
 

After it is started, open http: // 127.0.0.1: 8000/in the browser. If "It Works" appears, instead of 404 not found, it indicates that the startup is successful.

The default IP address set by runserver is 127.0.0.1 and the port is 8000. You can also specify an IP address, as shown in figure

 
Python manage. py runserver168.23.1.54 8080
 

4) customize your Hello world and create a new view. py file in the myblog module folder (including the _ init _. py folder ).

 
FromDjango. HTTPImportHttpresponseDefMyhelloworld (request ):ReturnHttprespnse ("Hello my Django!")
 

5) configure the URL path and change URLs. py to the following:

 From Django. conf. URLs Import  Patterns, include, URL  From Myblog. Views Import  Myhelloworld  From Django. contrib Import  Adminadmin. autodiscover () urlpatterns = Patterns ( ''  ,  #  Examples:     #  URL (R' ^ $ ', 'myblog.
