在生产上部署Django
Django的部署可以有很多方式,采用nginx+uwsgi的方式是其中比较常见的一种方式。
uwsgi介绍
uWSGI是一个Web服务器,它实现了WSGI协议、uwsgi、http等协议。Nginx中HttpUwsgiModule的作用是与uWSGI服务器进行交换。
要注意 WSGI / uwsgi / uWSGI 这三个概念的区分。
- WSGI是一种Web服务器网关接口。它是一个Web服务器(如nginx,uWSGI等服务器)与web应用(如用Flask框架写的程序)通信的一种规范。
- uwsgi是一种线路协议而不是通信协议,在此常用于在uWSGI服务器与其他网络服务器的数据通信。
- 而uWSGI是实现了uwsgi和WSGI两种协议的Web服务器。
- uwsgi协议是一个uWSGI服务器自有的协议,它用于定义传输信息的类型(type of information),每一个uwsgi packet前4byte为传输信息类型描述,它与WSGI相比是两样东西。
uwsgi性能非常高
uWSGI的主要特点如下
- 超快的性能
- 低内存占用(实测为apache2的mod_wsgi的一半左右)
- 多app管理(终于不用冥思苦想下个app用哪个端口比较好了-.-)
- 详尽的日志功能(可以用来分析app性能和瓶颈)
- 高度可定制(内存大小限制,服务一定次数后重启等)
总而言之uwgi是个部署用的好东东,正如uWSGI作者所吹嘘的:
If you are searching for a simple wsgi-only server, uWSGI is not for you, but if you are building a real (production-ready) app that need to be rock-solid, fast and easy to distribute/optimize for various load-average, you will pathetically and morbidly fall in love (we hope) with uWSGI.

为你的项目生成Nginx配置文件
You will need the uwsgi_params
file, which is available in the nginx
directory of the uWSGI distribution, or from https://github.com/nginx/nginx/blob/master/conf/uwsgi_params
Copy it into your project directory. In a moment we will tell nginx to refer to it.
Now create a file called mysite_nginx.conf, and put this in it:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 |

This conf file tells nginx to serve up media and static files from the filesystem, as well as handle requests that require Django’s intervention. For a large deployment it is considered good practice to let one server handle static/media files, and another handle Django applications, but for now, this will do just fine.
Symlink to this file from /etc/nginx/sites-enabled so nginx can see it:

Deploying static files
Before running nginx, you have to collect all Django static files in the static folder. First of all you have to edit mysite/settings.py adding:

and then run

此时启动Nginx 和Uwsgi,你的django项目就可以实现高并发啦
