Issue when setting-up wsgi as an alias path in apache

Question

NOTE: This question is different from ' Add a prefix to all Flask routes ' as I am trying to resolve this at apache level. Additional, the suggested fix for flask routes did not work!

Following on from this post , I'm trying to set up apache to serve PHP files by default, but point a given alias (ie /flaskapp ) to a wsgi path. The wsgi file in turn routes requests to a python flask app.

Here's the apache config that I'm trying (under 000-default.conf ):

<VirtualHost *:80>
        ServerName localhost
        ServerAdmin webmaster@localhost

        Alias / /var/www/html/
        <Directory "/var/www/html">
            Order Deny,Allow
            Allow from all
            Require all granted
        </Directory>

        WSGIScriptAlias /flaskapp "/var/www/flaskapp/deploy.wsgi"
        <Directory /var/www/flaskapp>
                 Options +ExecCGI
                 Order allow,deny
                 Allow from all
        </Directory>
</VirtualHost>

After doing a service apache2 restart I find that requests to http://myip/flaskapp result in a 404 error. Everything else works fine.

Things I've tried so far:

• Double checking all the file and folder paths (no issues found)
• Using the wsgi part of the above code to set up the wsgi app as a standalone virtualhost (works fine)
• Adding app.config['APPLICATION_ROOT'] = '/flaskapp' to my app.py file, as suggested the question ' Add a prefix to all Flask routes ' (Didn't have any effect)

Where could I be going wrong?

Instead of:

    Alias / /var/www/html/
    <Directory "/var/www/html">
        Order Deny,Allow
        Allow from all
        Require all granted
    </Directory>

use:

    DocumentRoot /var/www/html/
    <Directory "/var/www/html">
        Order Deny,Allow
        Allow from all
        Require all granted
    </Directory>

Using '/' with Alias takes precedence over everything else including mod_wsgi's ability to intercept requests at a sub URL. So for stuff at root of the site you need to use DocumentRoot directive.
