Django + Uwsgi + Nginx 实现生产环境部署

今天老男孩IT教育Python教学导师吴sir带你用Django + Uwsgi + Nginx 实现生产环境部署

3、nginx安装配置
4、django with nginx
如何在生产上部署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

1、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。
2、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。
3、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。
4、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的主要特点如下
1、超快的性能2、低内存占用（实测为apache2的mod_wsgi的一半左右）3、多app管理（终于不用冥思苦想下个app用哪个端口比较好了-.-）4、详尽的日志功能（可以用来分析app性能和瓶颈）5、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.

Uwsgi 安装使用

基本测试Create a file called

test.py

:运行

用uwsgi 启动django

　　可以把参数写到配置文件里


启动　　

Nginx安装使用　　

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_paramsCopy 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、# mysite_nginx.conf2、 3、# the upstream component nginx needs to connect to4、upstream django {5、 # server unix:///path/to/your/mysite/mysite.sock; # for a file socket6、 server 127.0.0.1:8001; # for a web port socket (we'll use this first)7、}8、 9、# configuration of the server10、server {11、 # the port your site will be served on12、 listen 8000;13、 # the domain name it will serve for14、 server_name .example.com; # substitute your machine's IP address or FQDN15、 charset utf-8;16、 17、 # max upload size18、 client_max_body_size 75M; # adjust to taste19、 20、 # Django media21、 location /media {22、 alias /path/to/your/mysite/media; # your Django project's media files - amend as required23、 }24、 25、 location /static {26 alias /path/to/your/mysite/static; # your Django project's static files - amend as required27、 }28、 29、 # Finally, send all non-media requests to the Django server.30、 location / {31、 uwsgi_pass django;32、 include /path/to/your/mysite/uwsgi_params; # the uwsgi_params file you installed33 }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:

此时启动Nginx 和Uwsgi，你的django项目就可以实现高并发啦！
