Some days ago, I read this tweet by @jessenoller (via @DZPM):

The future is DUNG: Django, Unix, Nginx, Gunicorn. I plan on asking HR to look for DUNG on all resumes.

What the heck is Gunicorn, I wondered… In short, Gunicorn is a Python WSGI HTTP Server easy to set up that gets on well with Django. Running Django apps using my beloved nginx gets faster and easier using Ubuntu Lucid Lynx. Look below…

• Install packages (I assume you’ve already set up nginx)

# apt-add-repository ppa:bchesneau/gunicorn
# aptitude update
# aptitude install gunicorn supervisor python-setuptools

• Edit settings.py in your Django app and add gunicorn to your INSTALLED_APPS

INSTALLED_APPS = (
  'django.contrib.auth',
  ...
  'gunicorn',
  ...
)

• Setup the supervisor of Django process in /etc/supervisor/conf.d/djangoapp.conf

[program:djangoapp]
command=/usr/bin/python /path/to/your/app/manage.py run_gunicorn
directory=/path/to/your/app
user=www-data
autostart=true
autorestart=true
redirect_stderr=True

• Restart supervisor
• Setup nginx

upstream app_server_djangoapp {
    server localhost:8000 fail_timeout=0;
}

server {
	listen X.X.X.X:80;
	server_name  .example.com;

	access_log  /var/log/nginx/example.com.access.log;
	error_log  /var/log/nginx/example.com.error.log info;

    keepalive_timeout 5;

    # path for static files
    root /path/to/your/app/media;

    location / {
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;

        if (!-f $request_filename) {
            proxy_pass http://app_server_djangoapp;
            break;
        }
    }
}

• Have fun

It was crystal clear LAMP’s time was over, could DUNG be the next fashionable acronym in free software web apps world?
