#### 一:安装python,安装django,使用虚拟环境 Virtualenv ####

[python3的安装方法]: http://blog.csdn.net/xudailong_blog/article/details/78309857 [django的安装方法]: pip install django==1.10.6(指定版本,如果不进行指定的话为最新的,现在最新打为1.11.6) [虚拟环境 Virtualenv] 当然,这里我暂时没有用到

#### 二:运行django项目 ####

1 . 新建一个project目录

注释:因为我这里之前已经创建一个`blogproject` 的文件了,并且里面也是有`django`项目,我先创建打文件`djangoblog` 然后`cd`进去,再运行命令:`django-admin startproject blogproject` 创建了一个`blogproject`的项目,我们使用`tree`看下目录结构,其中这就是django的目录结构,然后我们运行django项目:

> python manage.py runserver

snakeson@snakeson-Inspiron-5421:~/developer/django/djangoblog$ cd blogproject
    snakeson@snakeson-Inspiron-5421:~/developer/django/djangoblog/blogproject$ ls
    blogproject  manage.py
    snakeson@snakeson-Inspiron-5421:~/developer/django/djangoblog/blogproject$ python manage.py runserver
    Performing system checks...
    
    System check identified no issues (0 silenced).
    
    You have 13 unapplied migration(s). Your project may not work properly until you apply the migrations for app(s): admin, auth, contenttypes, sessions.
    Run 'python manage.py migrate' to apply them.

    Django version 1.10.6, using settings 'blogproject.settings'
    Starting development server at http://127.0.0.1:8000/
    Quit the server with CONTROL-C.

这里告诉我们需要`python manage.py migrate`  
这里的意思是需要数据库进行同步一下的意思,这里可以看下自学课堂里面的内容.有说的,  
那我们进行运行一下:  
`python manage.py migrate`

出现了这个界面:

snakeson@snakeson-Inspiron-5421:~/developer/django/djangoblog/blogproject$  python manage.py migrate
    Operations to perform:
      Apply all migrations: admin, auth, contenttypes, sessions
    Running migrations:

      Applying auth.0001_initial... OK
      Applying admin.0001_initial... OK
      Applying admin.0002_logentry_remove_auto_add... OK

    snakeson@snakeson-Inspiron-5421:~/developer/django/djangoblog/blogproject$

我们再运行一下:`python manage.py runserver`

这样就ok了:

1 通过网页打开:127.0.0.1:8080

1 将django 中文化:

需要在settings.py 下找到

LANGUAGE_CODE = 'en-us'
    
    TIME_ZONE = 'UTC'

改为:

LANGUAGE_CODE = 'zh-hans'
    
     TIME_ZONE = 'Asia/Shanghai'
