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
1234# Install the latest stable>pip install uwsgi# ... or if you want to install the latest LTS (long term support)>pip install https://projects.unbit.it/downloads/uwsgi-lts.tar.gz 基本测试
Create a file called test.py:
12345# test.pydef application(env, start_response): start_response('200 OK', [('Content-Type','text/html')]) return [b"Hello World"] # python3 #return ["Hello World"] # python2 运行
1uwsgi --http :8000 --wsgi-file test.py用uwsgi 启动django
1uwsgi --http :8000 --module mysite.wsgi 可以把参数写到配置文件里

1/usr/local/bin/uwsgi crazye-uwsgi.iniNginx安装使用
12sudo apt-get install nginxsudo /etc/init.d/nginx start # start nginx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、# mysite_nginx.conf
2、
3、# the upstream component nginx needs to connect to
4、upstream django {
5、 # server unix:///path/to/your/mysite/mysite.sock; # for a file socket
6、 server 127.0.0.1:8001; # for a web port socket (we'll use this first)
7、}
8、
9、# configuration of the server
10、server {
11、 # the port your site will be served on
12、 listen 8000;
13、 # the domain name it will serve for
14、 server_name .example.com; # substitute your machine's IP address or FQDN
15、 charset utf-8;
16、
17、 # max upload> 18、 client_max_body_size 75M; # adjust to taste
19、
20、 # Django media
21、 location /media {
22、 alias /path/to/your/mysite/media; # your Django project's media files -
amend as required
23、 }
24、
25、 location /static {
26 alias /path/to/your/mysite/static; # your Django project's static files - amend as required
27、 }
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 installed
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:
