Can't get Django-CMS to work with Apache and mod_wsgi

Question

I am trying to get django-cms to run with apache wsgi. I am using Python 3.12 and the latest version of all software (a fresh bare metal install of ubuntu 24.04). Django-cms runs with runserver.

My vhost file:

Define impact_lab_partners_path /home/mark/python-projects/impact_lab_partners
WSGIApplicationGroup %{GLOBAL}
<VirtualHost *:80>
 ServerName impactlabpartners.com
 ServerAlias www.impactlabpartners.com
 ServerAdmin xxxxxxxxxxxxxxxxx
 DocumentRoot /home/mark/python-projects/impact_lab_partners
 
 ProxyRequests off
 ProxyPreserveHost On
 
 WSGIDaemonProcess ilp python-home=/home/mark/.virtualenvs/impact_lab_partners python-path=${impact_lab_partners_path}/impact_lab_partners
 WSGIProcessGroup ilp
 WSGIScriptAlias / ${impact_lab_partners_path}/impact_lab_parthers/wsgi.py process-group=ilp
 Alias /static "/home/mark/Documents/impact_lab_partners/do_not_change/static"
 <Directory "/home/mark/Documents/impact_lab_partners/do_not_change/static">
 Require all granted
 </Directory>
 Alias /documents "/home/mark/Documents/impact_lab_partners/do_not_change/documents"
 <Directory "/home/mark/Documents/impact_lab_partners/do_not_change/documents">
 Require all granted
 </Directory>
 <Directory ${impact_lab_partners_path}/impact_lab_partners>
 <Files wsgi.py>
 Require all granted
 </Files>
 </Directory>
 # LogLevel Debug
# LogLevel debug
# ErrorLog ${APACHE_LOG_DIR}/impact_lab_partners/error.log
# CustomLog ${APACHE_LOG_DIR}/impact_lab_partners/access.log combined
</VirtualHost>

I have verified the paths are correct.

The error I am getting in /var/log/apache2/error.log every second or so:

Fatal Python error: init_fs_encoding: failed to get the Python codec of the filesystem encoding

I tried googling for the missing module 'encodings' and nothing I found helped. I don't understand why the Python Path is not set. I have tried all sorts of paths for the python-home and python path values, but nothing seems to work.

• iklinac: Verify the supplied path and access permissions for whole of the path. -> www-data user has no access to /home folder by default

Answer 1

After further troubleshooting, I discovered there was a mispelled path statement in the apache3 .conf file. However, the real culprit seems to be that Ubuntu 22.04 changed the default permission for /home/user folders from 755 to 750. When I changed the /home/mark folder to 755, the site worked.
