Django application mod_wsgi error with apache

I’m hosting Django app on AWS ec2 with ubuntu 20.04 lts. I can run the app with venv on various ports. I want to bind the app with apache so that my users can visit my app with just the public DNS no ports, only on the default port. So I have installed apache2, mod_wsgi.
My virtual host configuration.

<VirtualHost *:80>
  ServerAdmin [email protected]
  DocumentRoot /var/www/html/app_folder

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
  
  Alias /static /var/www/html/app_folder/static

  <Directory /var/www/html/app_folder/static>
    Require all granted
  </Directory>

  Alias /static /var/www/html/app_folder/media

  <Directory /var/www/html/app_folder/media>
    Require all granted
  </Directory>


  <Directory /var/www/html/app_folder/main_app>
    <Files wsgi.py>
      Require all granted
    </Files>
  </Directory>

  WSGIDaemonProcess app_folder python-path=/var/www/html/app_folder python-home=/home/ubuntu/.local/lib/python3.8/site-packages/django/__init__.py

  WSGIProcessGroup app_folder
  WSGIScriptAlias / /var/www/html/app_folder/main_app/wsgi.py

</VirtualHost>

So after configuring this vhost i restart my apache2 but I get nothing on the public dns. Instead I get the following error logs on my /var/log/apache2/error.log

    Serving python or Django app through apache sometimes becomes hectic but it could be done. I had configured Django with apahce and also with nginx. Well when it come to django i think we should use gunicorn to serve django applications. I switched to nginx for this one. i created a service file which runs the app via gunicorn with 3 workers using the apps virtualenv. below is the service file.

    [Unit]
Description=Softopark gunicorn service by: Softopark.com
After=network.target

[Service]
User=nginx
Group=nginx
WorkingDirectory=/usr/share/nginx/html/softopark_cms_2
Environment="/home/ec2-user/Env/cms5-yYbXgITO/bin"
ExecStart=/home/ec2-user/Env/cms5-yYbXgITO/bin/gunicorn --workers 3 --bind 0.0.0.0:8000 cms_project.wsgi

[Install]
WantedBy=multi-user.target

    Working like a charm

    I think you set your python-path wrong on virtual host configuration.
    This should be something like this:

    WSGIDaemonProcess app_folder python-path=/home/ubuntu/.local/lib/python3.8/site-packages

    I have tasted the same bitter experience. I guess this is a problem of apache/mod_wsgi which is not looking on python3.9 but on python3.8 which is the default python package for ubuntu 20.04.

    Unfortunately, I don’t have anything clever/easy to suggest. I guess, the solution would be to build mod_wsgi module from source against python 3.9. However, this is not a trivial process and I have never done it myself so I cannot really confirm its validity.
