[ELI5] how to deploy django

[Walter Wang]

 I tried my best to follow the various guides out there, but the official documentation here https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/modwsgi/ has different instructions than the instructions here, https://www.digitalocean.com/community/articles/using-mod_wsgi-to-serve-applications-on-ubuntu-12-04

I have been at this for over a week now, and I can't figure out how to deploy django with mod_wsgi and apache on a linux web server.

Can someone give or point to me a step to step instruction on how to deploy django?

Specifically,
1. what do I do with the httpd.conf file?
2. wsgi file? what's the difference between "making a wsgi file" and a wsgi.py file? For example


"wsgi file"

import os
import sys	
sys.path.append('~/public_html/domain1.com/')
os.environ['DJANGO_SETTINGS_MODULE'] = 'MyTestProject.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

"wsgi.py"

import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mywebsite.settings")

from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Thank you for any help.

Follow the digitalocean instructions. The official Django
documentation assumes you are across Apache and how mod_wsgi works in
general, and therefore doesn't give step-by-step instructions.

Follow the digitalocean instructions and don't touch this file (for
reference, it is referring to /etc/apache2/httpd.conf).

They're the same thing. mod_wsgi doesn't care what the extension is.
The content in your two examples is slightly different as one was
written for an older version of Django.

If you're still stuck, you'll need to provide more details like -
Linux distribution and version, Django version, Apache version, path
to project, virtual host file contents, the output when you use the
'wget' command to visit the website, and also anything in the Apache
log files.

Follow the digitalocean instructions.

I don't necessarily agree. The digitalocean instructions seem to be for Django version 1.4 (annoyingly, they don't specify which version it applies to, and don't even put a year on the datestamp of the article). Various changes have been made to the default configuration of Django since then. The OP needs to specify which version of Django they are using.

In any case, the digitalocean instructions are simply wrong in at least one important detail: you should not put your Django code under /public_html.

+1 for official documents, assuming you are using Django 1.6

Good clear guidance on mod_wsgi with Apache
https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/modwsgi/

Good guidance on wsgi if a little verbose
https://docs.djangoproject.com/en/1.6/howto/deployment/wsgi/

As per the docs for version 1.6 it is wsgi.py

Your project is named MyTestProject.settings here

Your project is named mywebsite.settings here

Perhaps you renamed part of your project?
If your project is named mywebsite located at /usr/local/www/domain1.com
then the wsgi.py file should contain something like the following six lines:

import os
import sys
sys.path.append('/usr/local/www/domain1.com')

os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mywebsite.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()

Thanks alot for all your answers, I really appreciate it.

I am using ubuntu 12.04 lts hosted on digitalocean. Apache version is 2.2.2 and django is 1.6, I created a virtualenv in the home directory, named myproject, I am using python3.2 as the interpreter in the virtualenv.

All your answers has given renewed energy.

So from reading all your answers, based on having django 1.6. I should edit the wsgi.py file and I don't have to make a "wsgi file" according to the digital ocean instructions.

What about the httpd.conf file? According to sam I should not touch it, but the official documentation for 1.6 says otherwise.

[Daniel Roseman]

No, in Debian-based distributions like Ubuntu, the specific configuration for each virtual host is in the sites-available directory. Follow the DigitalOcean instructions for that part, except that the WSGIScriptAlias should point to your existing wsgi.py file, which you should not need to edit.

Hi, I am using Debian Wheezy and this is my configuration. This is the
content of /etc/apache2/sites-available/mysitedomain.com. I made this
file following the official django docs.

Keep in mind that this is a deployed for testing purposes site so both
static files and django files are served from the same server, against
django guidelines. I am posting it here just to give you an example.

I am using the wsgi.py file created by startproject and I don't know if
I can keep it when I go live. For that maybe we can get some experienced
advice.

Also I had to rename the /etc/apache2/sites-available/default.<whatever>
to default.bak so apache wouldn't default to that.

No need for httpd.conf file. I couldn't find any in my server anyway.

The project is named ssite and the projects folder is simply it's parent
folder.

Hope this helps

The latest “Two Scoops of Django” book claims to have good info on deploying; I’ve not read it yet.
