Getting 500 Internal Server Error when Deploying Django Project in Linux Server using ubunto 18.04 Apache

Question

I have deployed a Django Project using 18.04 and before using Apache I was testing using Portal:8000 and it worked perfectly fine when I added Apache and made the required changes I am getting 500 Internal Server Error and in the log I am getting the following error

Update: I have made the following changes but still the same error: in the wsgi.py

import os
import sys
from django.core.wsgi import get_wsgi_application

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'project.settings')

# Add individual virtual environment packages at the end of sys.path; global env $
sys.path.append('/home/user/project/venv/lib/python3.8/site-packages')

# Add individual virtual environment packages at the beginning of sys.path; indiv$
sys.path.insert(0, '/home/user/project/venv/lib/python3.8/site-packages')

# Add the path to the 'project' Django project
sys.path.append('/home/user/project')

application = get_wsgi_application()

in the port 80 config:

#       Alias /static /home/user/project/static
#       <Directory /home/user/project/static>
#               Require all granted
#       </Directory>
#       Alias /media /home/user/project/media
#       <Directory /home/user/project/media>
#               Require all granted
#       </Directory>
#       <Directory /home/user/project/project>
#               <Files wsgi.py>
#                       Require all granted
#               </Files>
#       </Directory>
#       WSGIScriptAlias / /home/user/project/project/wsgi.py
#       WSGIDaemonProcess project python-path=/home/user/project:/home/user$
#       WSGIProcessGroup project

My question: What am I doing wrong and how to fix it. Note that I downloaded Pytohn 3.8 to the server and the Django site was working perfectly fine, not sure what went wrong

you need to set paths to virt.env and app folders:

in httpd.conf:

WSGIPythonHome "d:/..../django_project/env_folder"
WSGIPythonPath "d:/..../django_project/app_name"

alternatively set paths in wsgi.py dynamically and remove WSGIPythonHome/WSGIPythonPath from apache *.conf:

wsgi.py:


# place this before(!!) any package import that belongs to virtual env

# replacement for WSGIPythonHome "d:/..../django_project/env_folder"
# choose one:
sys.path.append('d:/.../env_folder/lib/site-packages')              # add individual virt.environment packages at the end of sys.path;  global env packages have prio
sys.path.insert(0,'d:/.../env_folder/lib/site-packages')            # add individual virt.environment packages at the beginning of sys.path;  indiv. virt.env packages have prio over global env
    
# replacement   WSGIPythonPath "d:/..../django_project/app_name"    
sys.path.append('d:/.../django_project/app_name')                   # add indiv. app folder to search path      

# after that the other wsgi.py stuff like .. 
from django.core.wsgi import get_wsgi_application

I made the changes but still the same error I updated the post — A_K, Feb 25 '23 at 04:31
