Django and mod_wsgi deploy example

So what do we do next when we finished to develop(debug, debug… debug…!) our application? We go and deploy it of course!

Well, a common choice of deploying Django application is to use Apache httpd and mod_wsgi.

Let’s suppose the following scenario:

• our application name is marina
• our application is placed inside /home/ directory
• our static files (javascript, images, css etc…) are inside /home/marina/media/

The first step is to create the WSGI file and place it inside /home/marina/

With the following content:

view sourceprint?

01	#!/usr/local/bin/python

02	import os, sys

03	sys.path.append('/home/')

04	sys.path.append('/home/marina/')

05	os.environ['DJANGO_SETTINGS_MODULE'] = 'settings'  # this is your settings.py file

06	os.environ['PYTHON_EGG_CACHE'] = '/tmp'

07

08	import django.core.handlers.wsgi

09

10	application = django.core.handlers.wsgi.WSGIHandler()

The second step is to edit your httpd.conf and add the following lines.

view sourceprint?

01	<Directory "/home/marina/media">

02	Order deny,allow

03	Allow from all

04	</Directory>

05

06	<Directory "/home/marina">

07	AllowOverride All

08	Order deny,allow

09	Allow from all

10	</Directory>

11

12	Alias /media/ /home/marina/media/

13	ServerAdmin admin@djangofoo.com

14	ErrorLog "logs/marina.com-error_log"

15	CustomLog "logs/marina.com-access_log" common

16	# mod_wsgi configuration is here

17	# we are running as user/group 'deamon', if you don't have those you need to change or create.

18	WSGIDaemonProcess marina user=daemon group=daemon processes=2 threads=25

19	WSGIProcessGroup marina

20	# this is our WSGI file.

21	WSGIScriptAlias / /home/marina/marina.wsgi

We need to be sure that our folder is readable by the ‘daemon‘ user

view sourceprint?

1	chown -R daemon /home/marina

NOTE: if you are using /media/ to store all the static files be sure you have this inside your settings.py

view sourceprint?

1	ADMIN_MEDIA_PREFIX = '/admin_media/' # by default this is /media/ which conflicts with our /media/ !!

And finally don’t forget to restart your apache.

If you still have issues to run a Django application its worth checking the error logs.
