Django + uWSGI via NGINX on Ubuntu 11.10 - django

Question

I'm trying do deploy a django project. I tried a lot of tutorials, but had no luck. I use a new clean Ubuntu 11.10. I've performed
apt-get install nginx
apt-get install uwsgi
service nginx start
I've created folder /deploy/project1 and put there manage.py and other files.
My current /deploy/project1/project1/wsgi.py contains:
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "project1.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
So, could you tell me how to deploy my django app for domain.com properly?
I've also installed Django via pip and easy_install
What should I add in /etc/nginx/sites-enabled/default.

Assuming that you have installed all requirement and you are using the aptitude packages then you don't need the wsgi.py. All the configuration is in the uwsgi ini/xml/yaml file. (take the format that you prefer).
Here is a minimal example for example.com file for nginx(/etc/nginx/sites-available/examplecom for ubuntu 11.10)
server {
listen 80;
server_name example.com;
access_log /var/log/nginx/projectname.log;
location /media {
alias /vagrant/test/projectname/media/;
}
location /static {
alias /vagrant/test/projectname/static/;
}
location / {
uwsgi_pass unix:///run/uwsgi/projectname/socket;
include uwsgi_params;
}
}
Create a symbolic link to /etc/nginx/sites-enabled
sudo ln -s /etc/nginx/sites-available/examplecom /etc/nginx/sites-enabled/examplecom
or
sudo /usr/sbin/nxensite examplecom
You are done with NGINX.
Go to /etc/uwsgi/apps-available and create your ini file
sudo vim /etc/uwsgi/apps-available/projectname.ini
[uwsgi]
virtualenv=/home/vagrant/.virtualenvs/projectenv
thread=3
master=1
env = DJANGO_SETTINGS_MODULE=projectname.settings
module = django.core.handlers.wsgi:WSGIHandler()
chdir = /path/to/my/django/project
socket = /run/uwsgi/projectname/socket
logto = /var/log/uwsgi/projectname.log
Point your ini to /etc/uwsgi/apps-enabled/projectname.ini
sudo ln -s /etc/uwsgi/apps-available/projectname.ini /etc/uwsgi/apps-enabled/projectname.ini
For more information, see any of these files on your system:
/etc/uwsgi/apps-available/README
/etc/uwsgi/apps-enabled/README
/usr/share/doc/uwsgi/README.Debian.gz
/etc/default/uwsgi
You are done. You can now restart nginx & uwsgi
sudo service nginx restart
sudo service uwsgi restart
Cheers!

Do not forget that Debian's, Ubuntu's and its derivates' uwsgi package does not require installation of its Python plugin — uwsgi-plugin-python, because uWSGI does not necessarily uses only Python (there are plugins for Lua, Erlang and other languages). However, Django requires Python plugin. Install it:
sudo apt install uwsgi-plugin-python
Unlike PIP's installation, you should explicitly mention uwsgi's plugin used in the app's config by adding a plugins = python line to it (if you use Python), like this:
[uwsgi]
plugins = python
uwsgi-socket = /var/sockets/django.sock
chmod-socket = 660
chdir = /home/v/django
module = project.wsgi
Unless you do this, there will be no Python-specific options available. And Debian's/Ubuntu's uWSGI will be just quiet about it!
