I am running ubuntu-server 20 and I am trying to run django deplyments server on it with apache2 and libapache2-mod-wsgi-py3. I was having many errors but i somehow managed to fix them but I am stuck on this error:
django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: No module named 'psycopg2._psycopg'
psycopg2 and psycopg2-binary are installed in my env. Also I am using python version 3.9.

Deploying Multiple Django Websites with Apache & mod_wsgi Windows

I am using mod_wsgi in a virtualenv with Apache 2.4 and I want to serve multiple Django sites from the same server.

I have reviewed these posts:

running-multiple-django-projects-on-one-apache-instance-with-mod_wsgi/
Múltiples direcciones, un solo proyecto
how-to-use-mod-wsgi-for-hosting-multiple-django-projects-under-single-domain
but they have not worked for me.
The server is a Windows Server 2012R2
Please direct me what I should do to get both sites up and running.
Note: The websites work perfectly separate

I also have a similar problem. And I've already looked for many posts, one thing I noticed different from yours was the line:
WSGIScriptAlias / " S:/Site_1/site_1/site_1/wsgi_windows.py"
WSGIScriptAlias / " S:/Site_2/site_2/site_2/wsgi_windows.py"
I identify the site in the alias:
WSGIScriptAlias /site1 " S:/Site_1/site_1/site_1/wsgi_windows.py"
WSGIScriptAlias /site2 " S:/Site_2/site_2/site_2/wsgi_windows.py"
And I'm using process daemon:
WSGIScriptAlias /site1 /site1/wsgi.py
WSGIDaemonProcess site1_proc python-path=S:/Site_1/VirtualEnvSite_1/Lib/site-packages python-home="c:/users/mmyuser/appdata/local/programs/python/python36"
WSGIProcessGroup site1_proc
In my case it's still not working for some other reason. Which I haven't identified yet. Individual applications run correctly using reverse proxy. But when I activate both, one of them gives the error: AH00128: File does not exist: /var/www/html/myapp2/. Configuration files are identical.

Here are my config for setting up multiple projects apache | windows | wsgi

Apache with Wsgi Module changes in source file does not get affected immediately

Apache with Wsgi Module changes in django app source file does not get affected immediately but it reflects the changes only when the apache restarts.

Troubles with running django app via wsgi on ubuntu 17

I need your help.
I have an error when trying to run on wsgi my django project.
I'm using Ubuntu 17, Apache2, Django 2.0, Python 3.6
When I running from manage.py, everything is working, but when via wsgi got the next error :
AH01276: Cannot serve directory /var/cardsite/cardsite/: No matching
DirectoryIndex
(index.html,index.cgi,index.pl,index.php,index.xhtml,index.htm) found,
and server-generated directory index forbidden by Options directive
And don't know why, because I guess set everything correct. Bellow my configuration :
apache.conf
<VirtualHost *:80>
CustomLog /var/log/apache2/cardsite-access.log common
ErrorLog /var/log/apache2/cardsite-error.log
DocumentRoot /var/cardsite/cardsite/

</VirtualHost>
wsgi.py
import os
import sys
PROJECT_DIR = '/var/cardsite'
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "cardsite.settings")
def execfile(filename):
globals = dict( __file__ = filename )
exec( open(filename).read(), globals )
activate_this = os.path.join( '/var/venv_python36/bin', 'activate_this.py' )
execfile( activate_this )
from django.core.wsgi import get_wsgi_application
application = get_wsgi_application()
P.S. Permissions I have give on folder and all which inside.
P.S.S. Packages like "libapache2-mod-wsgi-py3" or "mod-wsgi" via pip3 also installed.
Thank you all for the any suggestion what's it can be

Don't set DocumentRoot to be a parent directory of your source code. If you were to take the WSGIScriptAlias out, people could download your source code. You should avoid the risk of that, even if WSGIScriptAlias currently intercepts everything under /. That DocumentRoot directory doesn't allow access may be part of the problem also.
Try:
<VirtualHost *:80>
CustomLog /var/log/apache2/cardsite-access.log common
ErrorLog /var/log/apache2/cardsite-error.log
DocumentRoot /var/cardsite/htdocs
<Directory /var/cardsite/htdocs>
Require all granted
</Directory>
Alias /static /var/cardsite/cardsite/static
<Directory /var/cardsite/cardsite/static>
Require all granted
</Directory>
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
WSGIDaemonProcess cardsite python-path=/var/cardsite python-home=/var/venv_python36
WSGIProcessGroup cardsite
WSGIApplicationGroup %{GLOBAL}
WSGIScriptAlias / /var/cardsite/cardsite/wsgi.py
<Directory /var/cardsite/cardsite>
<Files wsgi.py>
Require all granted
</Files>
</Directory>
</VirtualHost>
The WSGIApplicationGroup has been added as always a good idea to have that, with only one WSGI application delegated to the daemon process group.
Make sure you create the directory:
/var/cardsite/htdocs
Finally, you are missing a ServerName directive. So if this isn't the default VirtualHost, your request may not even be getting handled by this VirtualHost.

EC2: Deploying a django project with a apache server

I have set up an ec2 instance and I'm able to connect to it via ssh. I've installed apache, django, git and all the necessary dependencies.
I've managed to clone a git repository which is located in /home/ubuntu/.
I've also set up the configuration file in /etc/apache2/sites-enabled/hyper-blog.conf.
This is my hyper-blog.conf file:
<VirtualHost *:80>
ServerName ec2-52-11-240-28.us-west-2.compute.amazonaws.com
ServerAlias ec2-52-11-240-28.us-west-2.compute.amazonaws.com

WSGIDaemonProcess hyper-blog python-path=/home/ubuntu/hyper-blog:/usr/local/lib/python3.4/dist-packages
WSGIProcessGroup hyper-blog
WSGIScriptAlias / /home/ubuntu/hyper-blog/hyper-blog/wsgi.py
The problem is when I go to my public domain: ec2-52-11-240-28.us-west-2.compute.amazonaws.com it takes a while to load and eventually does not render anything.
I need to know how to get my application up and running. I've tried this documentation on digital ocean https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-apache-and-mod_wsgi-on-ubuntu-14-04,
but still doesn't work.
How can I get my application working without installing virtualenv?
