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.

Uwsgi 安装使用

# Install the latest stable release:
pip install uwsgi
# ... or if you want to install the latest LTS (long term support) release,
pip install https://projects.unbit.it/downloads/uwsgi-lts.tar.gz

基本测试

Create a file called test.py:

# test.py
def application(env, start_response):
  start_response('200 OK', [('Content-Type','text/html')])
  return [b"Hello World"] # python3
  #return ["Hello World"] # python2

运行

uwsgi --http :8000 --wsgi-file test.py

用uwsgi 启动django

uwsgi --http :8000 --module mysite.wsgi

可以把参数写到配置文件里

alex@alex-ubuntu:~/uwsgi-test$ more crazye-uwsgi.ini
 
 
[uwsgi]
http = :9000
#the local unix socket file than commnuincate to Nginx
socket = 127.0.0.1:8001
# the base directory (full path)
chdir = /home/alex/CrazyEye
# Django's wsgi file
wsgi-file = CrazyEye/wsgi.py
# maximum number of worker processes
processes = 4
#thread numbers startched in each worker process
threads = 2
 
#monitor uwsgi status
stats = 127.0.0.1:9191
# clear environment on exit
vacuum     = true

启动

/usr/local/bin/uwsgi crazye-uwsgi.ini

Nginx安装使用　　

sudo apt-get install nginx
sudo /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:

# mysite_nginx.conf
 
# the upstream component nginx needs to connect to
upstream django {
  # server unix:///path/to/your/mysite/mysite.sock; # for a file socket
  server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}
 
# configuration of the server
server {
  # the port your site will be served on
  listen   8000;
  # the domain name it will serve for
  server_name .example.com; # substitute your machine's IP address or FQDN
  charset   utf-8;
 
  # max upload size
  client_max_body_size 75M;  # adjust to taste
 
  # Django media
  location /media {
    alias /path/to/your/mysite/media; # your Django project's media files - amend as required
  }
 
  location /static {
    alias /path/to/your/mysite/static; # your Django project's static files - amend as required
  }
 
  # Finally, send all non-media requests to the Django server.
  location / {
    uwsgi_pass django;
    include   /path/to/your/mysite/uwsgi_params; # the uwsgi_params file you installed
  }
}

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:

sudo ln -s ~/path/to/your/mysite/mysite_nginx.conf /etc/nginx/sites-enabled/

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:

STATIC_ROOT = os.path.join(BASE_DIR, "static/")

and then run

python manage.py collectstatic　　

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