Apache + mod_wsgi + django error on windows 10 - django

I followed this guide exactly: https://www.codementor.io/#aswinmurugesh/deploying-a-django-application-in-windows-with-apache-and-mod_wsgi-uhl2xq09e
I am trying to deploy my django application for the first time ever using mod_wsgi and apache on windows 10.
As mentioned in the guide, I changed a few things:
wsgi_windows.py
activate_this = 'C:/pythonvenv/djangoproj/Scripts/activate'
# execfile(activate_this, dict(__file__=activate_this))
exec(open(activate_this).read(),dict(__file__=activate_this))
import os
import sys
import site
# Add the site-packages of the chosen virtualenv to work with
site.addsitedir('C:/pythonvenv/djangoproj/Lib/site-packages')
# Add the app's directory to the PYTHONPATH
sys.path.append('C:/pythonstuff/djangoproj')
sys.path.append('C:/pythonstuff/djangoproj/djangoproj')
os.environ['DJANGO_SETTINGS_MODULE'] = 'djangoproj.settings'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "djangoprog.settings")
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
httpd.conf i added the following two lines as given by: mod_wsgi-express module-config
LoadModule wsgi_module "c:/pythonvenv/djangoproj/lib/site-packages/mod_wsgi/server/mod_wsgi.cp38-win32.pyd"
WSGIPythonHome "c:/pythonvenv/djangoproj"

Everytime i try to run httpd.exe to start my webserver, it gives the following error and then doesn't start. The error is found in the logs.

I am not sure what went wrong... can anyone please advise? If not, is there any more hassle-free ways to deploy django on windows 10?

WSGI django ModuleNotFoundError: No module named 'django'

I have been trying forever to get my django api to deploy via apache. I have installed mod_wsgi for python 3.7 and my venv is using python 3.7.15. Trying to go to my django app url I am getting a 500 error.
Error log shows:

I originally had the wrong mod_wsgi installed (built for python2). I removed that and installed python3-mod_wsgi.x86_64 and changed module path in httpd.conf. I then realized that my mod_wsgi was for python version 3.7, but my application venv was running python 3.6.8. I then wiped the venv and created a new one with python 3.7.15. Changed the conf WSGIDAEMONPROCESS path to the correct 3.7 site-packages. Still same error.
Just installing a virtual environment is not enough, then you'll have to activate it.
Run pip install -r requirements.txt to install the required packages for the project.
The Error
The first error line states Target WSGI script '.../project/project/wsgi.py' cannot be loaded as Python module.
This means your environment variable DJANGO_SETTINGS_MODULE is not set properly. In order to do it, go to .bashrc and set it to the same value as in the asgi.py/wsgi.py file.
Run source .bashrc to reload the configuration file, and restart the bash terminal (or open a new one) where you're trying to run the application.
This should work.

Deploying django using Apache and mod_wsgi problem

Was able to create a working Django application and works fine in development (runserver). However, I'm currently stuck with my production build using Apache as the web server. Hope someone can help.
Have added the following lines in my httpd.conf file:
# ServerName localhost:80 # use this if you're running this on a VirtualBox VM or PC
ServerName localhost:8000
# Django Project
LoadFile "C:/Users/Anton/AppData/Local/Programs/Python/Python310/python310.dll"

Without the additional lines mentioned above, I can see the apache service running in background. However, once above lines have been added, the apache server is in stopped status. Below is the log file content.

Apache not getting access to virtual environment set up for Django project

I created a virtualenv named 'pyapps' and installed pinax and django in it.I've installed apache 2 and mod_wsgi.I created a directory named 'apache' inside my django project(testproject) and put 'django.wsgi' file inside that directory.Here is the content of my wsgi file:
import os
import sys
# put the Django project on sys.path
sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../../")))
os.environ['DJANGO_SETTINGS_MODULE'] = 'textpisodes.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
Then I created a directory '/check/www' and put my project folder and pyapps folder inside '/check/www'.I chmoded 777 on /check/www.
Finally I created a virtual host,it's content is as follows:
<VirtualHost *:80>
ServerAdmin myemail
ServerName djangoserver
WSGIDaemonProcess textpisodes user=rajat threads=10 python-path=/check/www
WSGIProcessGroup textpisodes
WSGIScriptAlias / /check/www/textpisodes/apache/django.wsgi

Order deny,allow
Allow from all
</Directory>
ErrorLog /var/log/apache2/error.log
LogLevel warn
CustomLog /var/log/apache2/access.log combined
</VirtualHost>
Now when I try to access 'http://djangoserver',all I'm getting is Internal Server Error.Here are the contents of my apache log file.

You need to add your virtual environment path so that apache/python can find modules there.
Either put this in your apache configuration (outside of VirtualHost entry)
WSGIPythonPath /home/me/virtualenv/env1/lib/python2.7/site-packages
Or put it in the sys.path in your wsgi file.

Configure mod_wsgi on Mac OS X?

I have been trying to configure mod_wsgi for two days and still no luck. Here is what I did:
Create a sample django project mysite. Run python manage.py runserver and make sure it's working
Create apache directory under mysite, create apache_django_wsgi.conf, mysite.wsgi and an empty __init__.py
Content of apache_django_wsgi.conf:
WSGIPythonHome /usr/bin
WSGIRestrictStdout Off
WSGIDaemonProcess django
WSGIProcessGroup django
Alias /site_media/ "/Users/Garth/Dev/web-app/mysite/media/"
<Directory "/Users/Garth/Dev/web-app/mysite/media">

<Directory "/Library/Python/2.6/site-packages/django/contrib/admin/media">
Order allow,deny
Options Indexes
Allow from all
IndexOptions FancyIndexing
</Directory>
WSGIScriptAlias /mysite "/Users/Garth/Dev/web-app/mysite/apache/mysite.wsgi"
<Directory "/Users/Garth/Dev/web-app/mysite/apache">
Allow from all
</Directory>
Content of mysite.wsgi
import os
import sys
sys.path.append('/Users/Garth/Dev/web-app/mysite')
sys.path.append('/Users/Garth/Dev/web-app')
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
Download mod_wsgi.so (precompiled binary for Mac OS X) and put it in /usr/libexec/apache2
Edit /etc/apache2/httpd.conf,
add:
LoadModule wsgi_module libexec/apache2/mod_wsgi.so
Include /Users/Garth/Dev/web-app/mysite/apache/apache_django_wsgi.conf
Run sudo apachectl -k start
If I go to localhost, I can see the files and directories list. But if I go to localhost/mysite (which is the WSGIScriptAlias I configured), I got Internal Server Error.
The error_log of apache is:

Does anyone see where goes wrong? The error_log seems to tell a lot. I'm new to web development, and I might have made some obvious mistakes. Thank you very much!
Don't set WSGIPythonHome for a start it isn't needed. It should only be needed in certain situations and this isn't one of them.
In this case you have set it to a wrong value. By rights the fact it is wrong shouldn't have caused a problem as Python should have fallen back to using correct default value, but it may not do that for some reason.
You can also delete the line:
WSGIRestrictStdout Off
as that isn't needed for mod_wsgi 3.3.
