Question

I get in my error.log the following:

 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1]   [Errno 13] Permission denied:     '/Dropbox/project/www/mod_wsgi/egg-cache'
 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1] 
 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1] The Python egg cache directory is currently set to:

 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1]   /Dropbox/project/www/mod_wsgi/egg-cache

 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1] Perhaps your account does not have write access to this directory?  You can
 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1] change the cache directory by setting the PYTHON_EGG_CACHE environment
 [Tue May 03 16:42:21 2011] [error] [client 127.0.0.1] variable to point to an accessible directory.

what and how should i set it up?

UPDATE:

permissions currently:

drwxr-xr-x   4 petarpetrov  admin  136 Apr 30 13:38 mod_wsgi

Also, both User and Group of Apache both seem to be _www for some reason

Answer 1

In order to create files in a directory, the user Apache is running as needs to have write permissions to it. Currently Apache is running as _www user in the _www group, while petarpetrov owns the directory and is the only one allowed to write to it.

In order to allow _www to write to that directory you should change the group which owns it to _www and change the directory permissions:

chgrp _www /Dropbox/touchsofia/www/mod_wsgi/egg-cache
chmod g+w /Dropbox/touchsofia/www/mod_wsgi/egg-cache

This should change the group ownership to _www and allow that group to write to that directory. Depending on what goes into that directory, more permissions may be required.
