WSGIServer errors when trying to run Django app

Question

Firstly, here's my script:

#!/usr/bin/python
import sys, os

sys.path.append('/home/username/python')
sys.path.append("/home/username/python/flup")
sys.path.append("/home/username/python/django")
# more path stuff

os.environ['DJANGO_SETTINGS_MODULE'] = "project.settings"

from django.core.servers.fastcgi import runfastcgi
runfastcgi(method="threaded", daemonize="false")

As was described here.

And here's the error I get when trying to run it from shell:

WSGIServer: missing FastCGI param REQUEST_METHOD required by WSGI!
WSGIServer: missing FastCGI param SERVER_NAME required by WSGI!
WSGIServer: missing FastCGI param SERVER_PORT required by WSGI!
WSGIServer: missing FastCGI param SERVER_PROTOCOL required by WSGI!
Status: 404 NOT FOUND
Content-Type: text/html


<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html lang="en">
<!-- more html which looks to be the correct output -->

My question is, why aren't those params passed automatically by FastCGI? What am I doing wrong? Running the script from my web server just gives me an internal server error.

Instead of the last two lines of my script, I can use 

from flup.server.fcgi import WSGIServer
from django.core.handlers.wsgi import WSGIHandler
WSGIServer(WSGIHandler()).run()

But I still get the exact same error...

Was it helpful?

Solution

Solved it. This .htaccess file did the trick, for whatever reason. I swear I tried all this before...

AddHandler fcgid-script .fcgi
Options +FollowSymLinks
RewriteEngine On
RewriteBase /
RewriteRule ^(media/.*)$ - [L]
RewriteRule ^(adminmedia/.*)$ - [L]
RewriteCond %{REQUEST_URI} !(cgi-bin/myproject.fcgi)
RewriteRule ^(.*)$ cgi-bin/myproject.fcgi/$1 [L]

OTHER TIPS

The script expects those params to be passed as environment variables. Since they are not present in your shell environment, and the script is not running in the apache fastcgi environment (which provides them), it complains.

Do you have access to apache error logs? What do they say?

Does your host have mod_wsgi support? If so, you could use Django's wsgi handler:

import sys
import os

base = os.path.dirname(os.path.abspath(__file__)) + '/..'
sys.path.append(base)

os.environ['DJANGO_SETTINGS_MODULE'] = 'yourproject.settings'

import django.core.handlers.wsgi

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

Further instructions can be found on the modwsgi wiki, and the Django docs.
