正文之前

今天，本科的辅导员找到我，问我会不会做网站。。我比较虚，但是想想自己好歹做过。。所以就半推半就的接了话茬。。。 哎。。现在在愁找我建网站的老师会不会坑我。。

正文

虽说只要求我做个静态网站，可是甲方？呵呵。。不信。。我还是复习下Django吧，不然到时候被坑了简直想死。。这就开始从头到尾写一下

下面是搭建环境的教程：

How to install Django

直接pip安装就好了。。不要看那么多的。。。当然，python是必须要有的。我就不说了。

然后就可以查看版本：

root@zhangzhaobo:/home/ubuntu# python -m django --version
2.1

然后找个文件夹，开个项目吧：

root@zhangzhaobo:/home/ubuntu/python# django-admin startproject testsite

下面就是结构：

root@zhangzhaobo:/home/ubuntu/python# tree
.
├── apriori.py
└── testsite
    ├── manage.py
    └── testsite
        ├── __init__.py
        ├── settings.py
        ├── urls.py
        └── wsgi.py

忽略最上头那个文件，没啥用的。。

第一次运行可能会出现这个：

root@zhangzhaobo:/home/ubuntu/python/testsite# python manage.py runserver 0:8000

You have 15 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 2.1, using settings 'testsite.settings'
Starting development server at http://0:8000/
Quit the server with CONTROL-C.

按照要求来做就好了

^Croot@zhangzhaobo:/home/ubuntu/python/testsite# python manage.py migrate

  Applying sessions.0001_initial... OK

然后可以运行啦！

然后如果在一开始出现下列错误，只需小小调节就行：

DisallowedHost at /
Invalid HTTP_HOST header: '104.216.175.73:10086'. You may need to add u'104.216.175.73' to ALLOWED_HOSTS.

这个时候去setting.py里面改一下就好了
于是就去django-admin.py startproject testsite创建的项目中去修改 setting.py 文件：

ALLOWED_HOSTS = ['*']  ＃在这里请求的host添加了＊

然后就这样：

正文之后

OK！收工，下课！！
