Serving Multiple WSGI Applications As Different Virtual Hosts on Apache

I have an EC2 AWS server on which I would like to host a couple of Django applications. Each of these apps has its own URL. For instance,

example1.com example2.com

By itself, example1.com works. The problem is getting example2.com to work with it at the same time.

When I visit example2.com, I get an error:

DisallowedHost at /
Invalid HTTP_HOST header: 'example2.com'. You may need to add 'example2.com' to ALLOWED_HOSTS.
Request Method: GET
Request URL:    http://example2.com
Django Version: 1.9.13
Exception Type: DisallowedHost
Exception Value:    
Invalid HTTP_HOST header: 'example2.com'. You may need to add 'example2.com' to ALLOWED_HOSTS.

 '/var/www/vhosts/example1/example1-env/lib/python3.5/site-packages']
Server time:    Wed, 14 Jun 2017 20:31:27 +0000

As you can see, somehow Apache is trying to use the virtual environment of example1.com when it serves example2.com. How could I correct that? Each one should be served with its own virtualenv.

Here is the Apache configuration file:

    <VirtualHost *:80>
        # This is name based virtual hosting. So place an appropriate server name
        #   here. Example: django.devsrv.local
        ServerName  example1.com

        WSGIDaemonProcess example1 python-home=/var/www/vhosts/example1/example1-env
        WSGIProcessGroup %{GLOBAL}

        # Insert the full path to the wsgi.py-file here
        WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py

        <Directory /var/www/vhosts/example1/>
            Require all granted
        </Directory>

        Alias /static/ /var/www/vhosts/example1/static/

        <Directory /var/www/vhosts/example1/static/>
        Order deny,allow
        Allow from all
        </Directory>

        Alias /media/ /var/www/vhosts/example1/media/
        <Directory /var/www/vhosts/example1/media/>
        Order deny,allow
        Allow from all
        </Directory>

    </VirtualHost>

    <VirtualHost *:80>
        # This is name based virtual hosting. So place an appropriate server name
        #   here. Example: django.devsrv.local
        ServerName  example2.com
        WSGIDaemonProcess example2 python-home=/var/www/vhosts/example2/example2-env
        WSGIProcessGroup %{GLOBAL}

        # Insert the full path to the wsgi.py-file here
        WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py

        <Directory /var/www/vhosts/example2/>
            Require all granted
        </Directory>

        Alias /static/ /var/www/vhosts/example2/static/

        <Directory /var/www/vhosts/example2/static/>
        Order deny,allow
        Allow from all
        </Directory>

        Alias /media/ /var/www/vhosts/example2/media/
        <Directory /var/www/vhosts/example2/media/>
        Order deny,allow
        Allow from all
        </Directory>
  </VirtualHost>

Edit: Having read some suggestions in the comments, I have come to this. This still does not work.

ServerName  example1.com

WSGIDaemonProcess example1 display-name=%{GROUP} python-path=/var/www/vhosts/example1/ python-home=/var/www/vhosts/example1/example1-env/
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup example1

# Insert the full path to the wsgi.py-file here
WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py process-group=example1

...

ServerName  example2.com

WSGIDaemonProcess example2 display-name=%{GROUP} python-home=/var/www/vhosts/example2/example2-env/ python-path=/var/www/vhosts/example2/
WSGIApplicationGroup %{GLOBAL}
WSGIProcessGroup example2

# Insert the full path to the wsgi.py-file here
WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py process-group=example2

The following configuration worked for me. In short, it serves two different Django applications at example1.com and example2.com using their respective virtual environments.

As you can see, inserting the ServerAlias AND ServerName made all the difference, alongside a couple of other corrections by suggested by the community.

Apache configuration:

<IfModule !wsgi_module>
LoadModule wsgi_module modules/mod_wsgi.so
</IfModule>

<VirtualHost *:80>

    ServerName  www.example1.com
    ServerAlias example1.com

    WSGIDaemonProcess example1 display-name=%{GROUP} python-path=/var/www/vhosts/example1/ python-home=/var/www/vhosts/example1/example1-env/
    WSGIApplicationGroup %{GLOBAL}
    WSGIProcessGroup example1


    # Insert the full path to the wsgi.py-file here
    WSGIScriptAlias / /var/www/vhosts/example1/example1/wsgi.py process-group=example1

    <Directory /var/www/vhosts/example1/>
        Require all granted
    </Directory>

    Alias /static/ /var/www/vhosts/example1/static/

    <Directory /var/www/vhosts/example1/static/>
    Order deny,allow
    Allow from all
    </Directory>

    Alias /media/ /var/www/vhosts/example1/media/
    <Directory /var/www/vhosts/example1/media/>
    Order deny,allow
    Allow from all
    </Directory>
</VirtualHost>

<VirtualHost *:80>

    ServerName  www.example2.com
    ServerAlias example2.com

    WSGIDaemonProcess example2 display-name=%{GROUP} python-home=/var/www/vhosts/example2/example2-env/ python-path=/var/www/vhosts/example2/
    WSGIApplicationGroup %{GLOBAL}
    WSGIProcessGroup example2

    # Insert the full path to the wsgi.py-file here
    WSGIScriptAlias / /var/www/vhosts/example2/example2/wsgi.py process-group=example2

    <Directory /var/www/vhosts/example2/>
        Require all granted
    </Directory>

    Alias /static/ /var/www/vhosts/example2/static/

    <Directory /var/www/vhosts/example2/static/>
    Order deny,allow
    Allow from all
    </Directory>

    Alias /media/ /var/www/vhosts/example2/media/
    <Directory /var/www/vhosts/example2/media/>

</VirtualHost>
