Problems getting Django project to run in mod_wsgi - django

Question

I am having some issues getting a django project of mine to be properly served via mod_wsgi.
This is the first time I have tried something like this so please forgive any noob mistakes.
The error I am currently getting is as follows:
[Wed Oct 19 16:24:23 2016] [error] [client 140.225.0.153] mod_wsgi (pid=20418): Exception occurred processing WSGI script '/opt/badgr/code/apps/mainsite/wsgi.py'.
[Wed Oct 19 16:24:23 2016] [error] [client 140.225.0.153] Traceback (most recent call last):
[Wed Oct 19 16:24:23 2016] [error] [client 140.225.0.153] File "/opt/badgr/code/apps/mainsite/wsgi.py", line 14, in <module>
[Wed Oct 19 16:24:23 2016] [error] [client 140.225.0.153] from django.core.wsgi import get_wsgi_application
[Wed Oct 19 16:24:23 2016] [error] [client 140.225.0.153] ImportError: No module named wsgi
The main project directory is here:
/opt/badgr/
The project has its own virtualenv located here:
/opt/badgr/env/lib/python2.7/site-packages
My wsgi.py file:
"""
WSGI config for badgr project.
It exposes the WSGI callable as a module-level variable named ``application``.
For more information on this file, see
https://docs.djangoproject.com/en/1.7/howto/deployment/wsgi/
"""
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "mainsite.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
I also have a django.conf file located in /etc/httpd/conf.d/:
Alias /static /opt/badgr/code/staticfiles
<Directory /opt/badgr/code/staticfiles>
</Directory>
<Directory /opt/badgr/code/apps/mainsite/>
<Files wsgi.py>
</Files>
</Directory>
WSGISocketPrefix /var/run/wsgi/wsgi
WSGIDaemonProcess badgr python-path=/opt/badgr:/opt/badgr/env/lib/python2.7/site-packages/
WSGIProcessGroup badgr
WSGIScriptAlias / /opt/badgr/code/apps/mainsite/wsgi.py
As far as I can tell mod_wsgi is installed correctly in the virtualenv so I am not sure why I am seeing this error when trying to connect via http to the site.
Here is my httpd.conf:

WSGI is loaded via a file in conf.d:
LoadModule wsgi_module modules/mod_wsgi.so
I haven't really edited much in the HTTPD.conf file besides just removing the comments so I could fit it on here.
I also am not sure why python seems to be running 2.6.# for httpd instead of 2.7.
Any thoughts or additional information appreciated. Also let me know if I should provide anything else.

Answer 1

That error about django.core.wsgi is because you have a very old Django version installed, older than the version that your project was set up for.
This is likely going to be because your mod_wsgi is compiled for Python 2.6 and you have an older Django version installed in that Python installation.
If you want to use Python 2.7 you must reinstall mod_wsgi with one which is compiled for Python 2.7. You cannot force mod_wsgi compiled for Python 2.6 to use a virtual environment for Python 2.7.

Answer 2

Note: I provided this answer that uses the mod_wsgi in pip because I had to do this myself recently to get it running in FreeBSD using Python 3. It isn't commonly done this way, but it should work.
If you want to install mod_wsgi from pip then you should give Apache the right path to mod_wsgi or install the module pip it creates into the Apache installation. If you are running it on your system using apt-get or pkg or BSD ports, then listen to the wise advice of Graham.
There are other things that could simultaneously be wrong, however I believe the proximate error is that your application cannot import wsgi. You should go into your environment by doing:
cd /opt/badgr
. env/bin/activate
If that fails try source env/bin/activate
And then installing mod_wsgi:
pip install mod_wsgi
This will install a script called mod_wsgi-express which will allow you to run Apache/mod_wsgi as a development server from the command line. The script can also help you to install the module it compiles into your Apache.
First we have to deal with fact that Apache already has mod_wsgi module installed from system packages. The best thing to do is uninstall the system package for mod_wsgi. This will likely remove that file in conf.d with the LoadModule line for wsgi_module.
Next run:
sudo mod_wsgi-express install-module
This should copy the module into the Apache modules directory and output two lines with a LoadModule and WSGIPythonHome directive. Add a new wsgi.conf file under conf.d directory and add those two lines to it. Restart Apache.
Doing it from pip in your virtualenv ensures it creates the right version of mod_wsgi with respect to the version of python you are running.

Answer 3

Atleast for this problem I think it was that I didn't grant enough rights to the site-packages folder and its contents. I made some progress after doing that but am now running into other issues that I have opened in another thread.
I gave the site-packages folder rwx recursively for group apache.
Here is the next part of my issues:
