Question

Following this guide:

http://code.google.com/p/modwsgi/wiki/QuickConfigurationGuide

I was not able to configure a “Hello World” WSGI application (I did not mount at docroot and did not delegate to daemon)
on my ubuntu squeeze. Python version is 2.6.5.
I believe mod_wsgi is installed correctly.
Here is what I did:

• Created a user /home/wsgitest (I know we are not supposed to do this but it’s just for testing).

• Added the user to group www-data, which is what apache2 runs under:

  groups wsgitest
  wsgitest : wsgitest www-data
  

  As wsgitest, added permissions to read the folder explicitly:

  chmod -R g+rx wsgitest
  

• Created a WSGI Application Script File with the exact same contents from the guide:

  ls -la /home/wsgitest/
  (...)
  -rw-r--r-- 1 wsgitest wsgitest  277 May  7 17:11 application.wsgi
  

• Created an application config file:

  cat /etc/apache2/sites-available/application.conf 
  <VirtualHost *:80>
    WSGIScriptAlias /application /home/wsgitest/application.wsgi
    <Directory /home/wsgitest>
      Order allow,deny
      Allow from all
    </Directory>
  </VirtualHost>
  

(File belongs to root:root)

• Enabled the site:

  ls -la /etc/apache2/sites-enabled/
  (..)
  lrwxrwxrwx 1 root root   35 May  9 15:29 application.conf -> ../sites-available/application.conf
  

• Restarted apache2 and went to the following address:

  <ip-address>/application
  <ip-address>/application/
  

which gives 404.

• Disabled the site and put the follwing at bottom of file /etc/apache2/apache2.conf :

  <Directory /home/wsgitest>
    Order allow,deny
    Allow from all
  </Directory>        
  WSGIScriptAlias /application /home/wsgitetst/application.wsgi
  

• Restarted apache and tried to navigate again, no changes.

• Tried with lynx and localhost, no changes.

• Enabled logging info level in apache2. The /var/log/apache2 access log tells me that the request is answered with “404 503”,
  And this is from error.log:

  [Wed May 09 15:39:28 2012] [info] mod_wsgi (pid=27914): Attach interpreter ''.
  (...) 
  [Wed May 09 15:39:32 2012] [error] [client <ip>] File does not exist: /var/www/application
  (...)
  [Wed May 09 15:39:28 2012] [info] mod_wsgi (pid=27914): Cleanup interpreter ''.
  

The “other_vhosts_access.log” is empty.

To me it looks like the request never reaches the wsgi app or isn’t routed somehow…
Can anyone help me identify the problem?

Answer 1

Oh no. I did check everything 3 or 4 times but still there was a typo in there.
As you can see in the declaration of WSGIScriptAlias from the apache2.conf edit (wsgitetst).
The include config still won’t work, but that’s OK.
