Apache Django Internal Server Error (Ubuntu 18.04) - django

I have a Django wagtail application. I can run it in debug and I can run it on a django server but if I try to run it on my Ubuntu 18.04 server using Apache2 WSGI I get "Internal Server Error". Apache log:

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 + mod_wsgi + django error on windows 10

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"

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?

Why is apache2 not configured

I am trying to install the mod_wsgi module in apache to deploy a django project.
I am using the pre-installed apache2 in ubuntu.
After I installed the module, I was asked to verify if apache is loading properly the module by executing apache2ctl -M:
comon#mylocal:~$ apache2ctl -M
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

And it seems that there is no mod_wsgi so I found that I need to add LoadModule wsgi_module modules/mod_wsgi.so in the httpd.conf configure file in apache.
To know where this file is located, I ran: /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE AND I go:
comon#mylocal:~$ /usr/sbin/apache2 -V | grep SERVER_CONFIG_FILE

AH00526: Syntax error on line 74 of /etc/apache2/apache2.conf:

It seems that nothing is conigured in my apache2!
What I am doing wrong?
Use apachectl, not apache2/httpd executables directly, to pick up the customized environment variables sourced by apachectl on your distribution of apache.

Error 500 and other website's content

I have some small django projects working on the same server with apache and mod_wsgi. I installed another one project with virtualenvironment and set settings for it in Apache conf file:
<VirtualHost XXX.XXX.XXX.XXX:81 >

CustomLog /var/www/httpd-logs/mywebsite.com.access.log combined

When I try to load website server returns 500 error or another website's content in about 50% times and there are some strange errors in apache log files that I can't understand because it tries to load another website's project settings:

Another question is why it still uses default system python but not from virtualenv? Please help!
You cannot use different python executeables under the same apache due to the fact that WSGIPythonHome is set for all virtual hosts globally (see docs). If WSGIPythonHome is not set - mod_wsgi will use system python.
It seems like you have not set up wsgi.py correctly. Your goal in wsgi.py is to manipulate sys.path correctly so that all that your project needs is available. Here's what helped me when I had same problems: apache server not using proper virtualenv with WSGI setting.
Hope that helps.
Your configuration is missing:
WSGIProcessGroup mywebsite.com
Without that, your WSGI application isn't even going to be delegated to the daemon process group. You can check with:
http://code.google.com/p/modwsgi/wiki/CheckingYourInstallation#Embedded_Or_Daemon_Mode
Once you have daemon mode being used properly, so long as you are using mod_wsgi 3.4, you can set Python home for that specific daemon process group using:
WSGIDaemonProcess mywebsite.com python-home=/var/www/empirik/data/www/mywebsite.com/env
That way you can simply point at the root of the Python virtual environment and it will be picked up.
You still need though to specify the python-path option as well to the parent directory of your Django project so it and the settings module can be found, which is the problem you are having. Thus likely you want:
WSGIDaemonProcess mywebsite.com \
python-home=/var/www/empirik/data/www/mywebsite.com/env \
python-path=/var/www/empirik/data/www/mywebsite.com
Now if running only that site in the daemon process group, set:
WSGIApplicationGroup %{GLOBAL}
to avoid issues with C extension modules that don't work in sub interpreters.
To be safer, instead of:
<Directory /var/www/empirik/data/www/mywebsite.com/myproject>
Order deny,allow
Allow from All
</Directory>
you should use:
<Directory /var/www/empirik/data/www/mywebsite.com/myproject>
<Files wsgi.py>
Order deny,allow
Allow from All
</Files>
</Directory>
That way if screw up Apache configuration, less risk of someone downloading your code and settings file.
And where you have:
<Directory /var/www/empirik/data/www/mywebsite.com/myproject/static>
Order deny,allow
Allow from all
</Directory>
you would appear to be missing the corresponding:
Alias /media /var/www/empirik/data/www/mywebsite.com/myproject/static
If you don't have an Alias for static media directory, Apache will not serve up files there.
Finally, since you want to force daemon mode and want to avoid embedded mode, set:
WSGIRestrictedEmbedded On
That way if you screw up configuration and things run in embedded mode by mistake as you currently are, you will get an error.

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
<Directory /check/www/textpisodes/apache>
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.
