Django mod_wsgi apache

Question

When I try to visit my Django site at http://www.satoshi.example.com/mysite I get a 503 Service Temporary Unavailable.

The Apache error log says

[Tue Feb 28 07:11:09 2012] [error] [client 10.0.0.202] (13)Permission denied: mod_wsgi (pid=4756): Unable to connect to WSGI daemon process 'django' on '/etc/httpd/logs/wsgi.17555.4.1.sock' after multiple attempts.

Apache properly loads mod_wsgi

root@satoshi:~/html/mysite# apachectl -M | grep wsgi
 wsgi_module (shared)
Syntax OK

Apache loads /var/www/html/mysite/apache/apache_django_wsgi.conf which is

WSGIDaemonProcess django
WSGIProcessGroup django

<Directory "/var/www/html/mysite">
Order allow,deny
Options Indexes
Allow from all 
IndexOptions FancyIndexing
</Directory>

WSGIScriptAlias /mysite "/var/www/html/mysite/apache/django.wsgi"

<Directory "/var/www/html/mysite/apache">
Order deny,allow
Allow from all 
</Directory>

This is the /var/www/html/mysite/apache/django.wsgi

import os
import sys 

paths = [ '/var/www/html/mysite',
          '/usr/lib/python2.6/site-packages/',
]

for path in paths:
    if path not in sys.path:
        sys.path.append(path)

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

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

One weird thing is that I found out I don't even need to LoadModule wsgi_module modules/mod_wsgi.so on my own httpd.conf. I think my httpd.conf is an extension of another configuration that already loaded mod_wsgi. Not sure if this matters.

Is there anything wrong with what I provided so far? Let me know if you need more information. Thanks in advance!

Answer 1

This issue is documented in:

http://code.google.com/p/modwsgi/wiki/ConfigurationIssues#Location_Of_UNIX_Sockets

The solutions given by others of changing permissions are wrong.

The correct solution is to change where the socket files are kept to a location where Apache user can read them.

On systems which protect logs directory, they sometimes have a system in place to set back those permissions when you mess with them. As a result any change may only be temporary.
