Django MOD_PYTHON ERROR - django

I have had django running with mod_python for awhile now but today I get the following error

Any ideas why this is happening?

I can only guess what your problem might be, but here are two standard checks:
Import modpython in shell, from a couple different working directories
Change users (if you have any besides root set up) and repeat step 1
If #2 looks like more trouble than it's worth, then try very, very carefully examining permissions for each folder along the path to modpython to make sure that "other" has read access at every stage along the way. If you've moved django into your home directory (like I did once...not sure why, but got the same error) that'll be the problem. You either need to move it back into a directory where apache can read or you need to add read permission for other.

In my case pytonpath and access rights was ok.
This error disappeared after recompilation python.

I'm trying to host my flask application on apache2 running on ubuntu 20.04. I have wsgi already enabled as well as the site. I believe the error might be because of wrong configuration but the error log suggests something about no python frame. Here's a copy of the error log from /var/log/apache2/error.log `

Mod_wsgi fails to load django.core.handlers.wsgi

Ok, after 5-6 hours of trying, I give up. I have searched the web, tried all solutions suggested, but nothing is solving my problem.
Goal: Set up Django on my Ubuntu 12.04 VPS.
Problem: Exception occurred processing WSGI script [...] ImportError: No module named django.core.handlers.wsgi in /etc/log/apache2/error.log.
Solutions tried: 1) Appending the site-packages directory to the sys path in Djangos' wsgi.py file, 2) re-installing mod_wsgi, 3) making sure mod_wsgi is compiled for the same Python version as Django is installed with, 4) chmod 777 for the site-packages directory.
Environment: Ubuntu 12.04 VPS, Django installation in virtualenv, Python version 2.7.3, Django version 1.6.1, mod_wsgi built from mod_wsgi-3.4.tar.gz.
Full error message:

In your wsgi.py, try adding this to activate virtual env:

In you apache config, you mainly need only(No Deamon Process required):
WSGIScriptAlias / /var/www/mysite.com/djangoSite/djangoSite/wsgi.py
Alias /static/ /var/www/mysite.com/djangoSite/static/
See from the Create Virtual Host section of this link
Make sure you are using absolute paths in your Apache2 config file. I assume you have been able to run python manage.py shell to get a working Django shell? I would tackle the Apache2 config file; I'm sure your issue is there.
~/Envs/myEnv/lib/python2.7/site-packages
I think that's your problem right there: the ~ is, if it is expanded at all, expanded to the home of the www-data user. You can validate that by doing something like this:
import sys
print >> sys.stderr, sys.path
in your wsgi file; then check your error log. If it doesn't end up in the main error log, add an ErrorLog to your vhost to get per-vhost error logging.
Also, /root/ is not readable for the www-data user, you need to move your virtual env somewhere accessible.

apache 500 internal error when updating from django 1.3 to 1.4

Originally when I installed Django 1.3 with wsgi on my ubuntu server I used the included setup.py file and so when I wanted to update followed the Remove any old versions of Django section of the install guide by renaming the "django" folder in my site-packages "django.old" and then installing the new version by using the the setup.py file for Django 1.4
After restarting my apache server I got a standard 500 Internal error. I checked the apache error log and discovered that ADMIN_MEDIA_PREFIX has been deprecated so following the Django 1.4 release notes I removed ADMIN_MEDIA_PREFIX from the settings file and moved the admin files into the static directory under a folder called "admin" as indicated.
I restarted my apache server again and received the same standard 500 error but this time when I tried running a tail on the apache error log no new errors registered.
Without any further error messages I am really stuck so any help will be appreciated.
Below is the content of my apache site config file and the wsgi file
site config:
<VirtualHost *:80>
ServerAdmin me#mysite.com

ServerAlias mysite.com

Please note I have tried to remove or rename any identifying information from these files for security reasons, so if there is an obvious syntax error etc. it is probably due to this editing. The original versions of these files are the same accept for the name changes and worked well under Django 1.3
django 1.4 have a wsgi.py file configuratiom included:

Apache Django "client denied by server configuration" error

I found a similar question here, but didn't help me.
I basically have apache setup on my OS X. I also have Django installed.
However, when i try to load the page through the browser locally, i get:
Forbidden
You don't have permission to access / on this server.
I have an original httpd.conf with the only modification of enabling vhosts in which I have:
<VirtualHost *:80>
ServerAdmin webmaster#dummy-host.example.com
DocumentRoot "/Dropbox/project/www/"
ServerName touch.loc
# ServerAlias www.dummy-host.example.com
ErrorLog "/Dropbox/project/www/log/error.log"
CustomLog "/Dropbox/project/www/log/access.log" common
</VirtualHost>
And the error.log file gives:
[Tue May 03 20:22:56 2011] [error] [client 127.0.0.1] Directory index forbidden by Options directive: /Dropbox/project/www/
I read around and it looks like i have to add the following to the httpd.conf:
<Directory /Dropbox/project/www >
Order deny,allow
Allow from all
</Directory>
In which case i get:
[Tue May 03 20:27:55 2011] [error] [client 127.0.0.1] client denied by server configuration: /Dropbox/project/www/
Can someone help me fix this annoyance? How can I further Investigate it?
Does it have to do with users/groups?
UPDATE:
I then added the Options +Indexes and the permissions opened. However when i try to load the page, file structure appears instead of the wsgi file to pickup and load the website. What would be the reason for that?
here is my .wsgi file:
import os
import sys
sys.stdout = sys.stderr
# Add the virtual Python environment site-packages directory to the path
import site
site.addsitedir('/usr/lib/python2.6/dist-packages')
#If your project is not on your PYTHONPATH by default you can add the following
sys.path.append('/Dropbox/project/www/')
sys.path.append('/Dropbox/project/www/project')
# Avoid ``[Errno 13] Permission denied: '/var/www/.python-eggs'`` messages
os.environ['PYTHON_EGG_CACHE'] = '/Dropbox/project/www/mod_wsgi/egg-cache'
os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
You seem to be missing anything in your Apache configuration that actually serves the Django application. You need to read the Django mod_wsgi documentation - the first line of code there is what you're missing.
Note that your code should not live under the DocumentRoot.
The problem I see is in Dropbox folder
I have made so:
chmod o+x /home/your_name/Dropbox
That resolves permissions

Django mod_python deployment error

I'm trying to deploy a django project via mod_python and I keep getting an error saying a handler module is missing.
My apache config:
<Location />
SetHandler python-program
PythonHandler django.core.handlers.modpython
SetEnv DJANGO_SETTINGS_MODULE bookmarklet_server.settings
PythonOption django.root /
PythonDebug On
#PythonPath "['', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/usr/lib/pymodules/python2.6', '/usr/lib/pymodules/python2.6/gtk-2.0', '/usr/local/lib/python2.6/dist-packages']"
</Location>
The other path is from my attempt to just copy over the default pythonpath, but it didn't help.
A quick test in the python console shows the module should be accesible:

Perhaps django isn't in your Pythonpath?
Ok, managed to fix the problem.
This particular import issue was fixed by installing django rather than just having the svn trunk linked into dist-packages. Why this doesn't work for server processes I don't know.
But anyway, there were further issues which were solved by doing a CGI deployment via nginx and eventually the last problem (which also failed my wsgi deployment attempt) was that my /home dir, which is where the files were, was accessible only by myself.
I learned a lot today :)
