I am trying to use a django application on my local ubuntu machine. However the site doesn't work and my /var/log/apache2/errors.log
is filled with messages like this:
ImportError: No module named site
My /var/log/apache2/error.log
(for today) looks like this:
$ cat error.log | uniq -c
1 [Wed Jun 29 09:37:37 2011] [notice] Apache/2.2.17 (Ubuntu) mod_wsgi/3.3 Python/2.7.1+ configured -- resuming normal operations
12966 ImportError: No module named site
That's the notice that it started up when I turned on my machine, followed by 12,966 lines all saying the no module named site
message
note the lack of a datetime field. These errors are repeated even when not going to the website (i.e. even when not making web requests). When going to the website in a browser, it just hangs, as if waiting for a large download.
Settings
Apache modules
I am using a python 2.5 virtualenv with lots of packages (incl. django 1.1) installed with pip. I have mod_wsgi loaded:
$ ls -l /etc/apache2/mods-enabled/wsgi*
lrwxrwxrwx 1 root root 27 2010-10-04 16:50 /etc/apache2/mods-enabled/wsgi.conf -> ../mods-available/wsgi.conf
lrwxrwxrwx 1 root root 27 2010-10-04 16:50 /etc/apache2/mods-enabled/wsgi.load -> ../mods-available/wsgi.load
I use "tix" as a domain name that's set to localhost in /etc/hosts
$ grep tix /etc/hosts
127.0.0.1 tix
Apache config
Here is my apache configuration (You can see some attempts to make it work, commented lines etc.):
# mod-wsgi enabled virtual host

wsgi loader
Here is my loader.wsgi:
I used to have import site
in this file, which I thought might have caused the problem, but I removed it and the errors keep coming up.
# loader.wsgi - WSGI adapter for tix django project
# The python paste wrapper catches apache 500 errors (Internal Server Errors) and gives debug output
# See http://pythonpaste.org/modules/exceptions.html
import os
import sys
os.environ['DJANGO_SETTINGS_MODULE'] = 'tix.settings.base'
from paste.exceptions.errormiddleware import ErrorMiddleware
import django.core.handlers.wsgi
tixette = django.core.handlers.wsgi.WSGIHandler()
application = ErrorMiddleware(tixette, debug=True, error_email='operator@example.com', error_subject_prefix='Alert: wsgi loader python paste: ', error_log='/tix/1.0/logs/paste.log', show_exceptions_in_wsgi_errors=False)
This configuration used to work fine on Ubuntu 10.10, but since I upgraded to Ubuntu 11.04, I get the errors above.
