Django. Problems with Apache and mod_wsgi

Question

I have read this. So, I install mod_wsgi, virtualenv(virtualenv ENV). (Django 1.4, ubuntu server)

/etc/apache2/sites-available/mysite:

<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com
WSGIDaemonProcess example.com python-path=/home/user/cars/cars:/home/user/cars/ENV/lib/python2.7/site-packege
WSGIScriptAlias / /home/user/cars/cars/wsgi.py
<Directory /home/user/cars/cars>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>
</VirtualHost>
WSGIPythonPath /home/user/cars/ENV/lib/python2.7/site-packeges

I have Internal Server Error

in /var/log/apache2/error.log:

mod_wsgi (pid=3012): Exception occurred processing WSGI script '/home/user/cars/cars/wsgi.py'.
Traceback (most recent call last):

raise ImportError("Could not import settings '%s' (Is it on sys.path?): %s" % (self.SETTINGS_MODULE, e))
ImportError: Could not import settings 'cars.settings' (Is it on sys.path?): No module named cars.settings

Please, help me, I have never configure Django with mod_wsgi. Its my first project

Update:

Alias /favicon.ico /home/user/cars/files/static_content/favicon.ico 
AliasMatch ^/([^/]*\.css) /home/user/cars/files/static_content/css/$1 
Alias /static/ /home/user/cars/files/static_content/ 
<Directory /home/user/cars/files/static_content> 
 Order deny,allow
 Allow from all 
</Directory>

Please post your wsgi.py. Obviously your project isn't on sys.path. — Dirk Eschler

BTW, is it a bad cut and paste, or do you really have packages spelt wrong in both python-path and WSGIPythonPath? — Graham Dumpleton

You are missing the WSGIProcessGroup directive and so the WSGIDaemonProcess and its python-path option are not being used. The path set in WSGIPythonPath (which is for embedded mode only) is being used and in it you have not set the location of your project. Even for python-path to WSGIDaemonProcess you have the path wrong anyway.

Try with:

<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com
WSGIDaemonProcess example.com python-path=/home/user/cars:/home/user/cars/ENV/lib/python2.7/site-packages
WSGIProcessGroup example.com
WSGIScriptAlias / /home/user/cars/cars/wsgi.py
<Directory /home/user/cars/cars>
<Files wsgi.py>
Order deny,allow
Allow from all
</Files>
</Directory>
</VirtualHost>

noting the change to python-path and addition of WSGIProcessGroup.

yes, it works :) But I have one more truble: in cars I have dir 'files' and subdir 'static_content'. I use python manage.py collectstatic and it collects all static files to that directory. In Virtual host I have: (I update my first post). But it doesnt work (404 for css and img files). How to fix it?

If you got to the exact expected URL of the static file, what does Apache say in its error log file.
