apache2 not showing flask app on local server - flask

Question

I was following this tutorial:
https://pythonprogramming.net/creating-first-flask-web-app/?completed=/flask-web-development-introduction/
On my local server (home machine on local network).
Flask itself starts properly
>>> python /var/www/FlaskApp/FlaskApp/__init__.py
* Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)
127.0.0.1 - - [31/Oct/2016 22:56:29] "GET / HTTP/1.1" 200 -
127.0.0.1 - - [31/Oct/2016 22:56:29] "GET /favicon.ico HTTP/1.1" 404 -
flask starts
But Apache is showing its default webpage no matter what.
sudo a2enmod wsgi
Module wsgi already enabled
cat /var/www/FlaskApp/FlaskApp/init.py
from flask import Flask
app = Flask(__name__)
#app.route('/')
def homepage():
return "Hi There, how you're doin?"
if __name__ == "__main__":
app.run()(debug=True)
cat /etc/apache2/sites-available/FlaskApp.conf
<VirtualHost *>
ServerName dagzserv
ServerAdmin my#email.com
WSGIScriptAlias / /var/www/FlaskApp/flaskapp.wsgi
<Directory /var/www/FlaskApp/FlaskApp/>
Require all granted
</Directory>
Alias /static /var/www/FlaskApp/FlaskApp/static
<Directory /var/www/FlaskApp/FlaskApp/static/>
Require all granted
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
sudo a2ensite FlaskApp
Site FlaskApp already enabled
I have tried adding app.run(host='0.0.0.0', port=5000)
I do have /etc/hosts dagserv as my ip in localnetwork (10.0.1.xxx)
Also tried ServerName as localhost.
One thing i did not understood is how exactly Apache is finding that "FlaskApp.conf" but i assumed that it is scanning its config directory
(/etc/apache2/sites-available/FlaskApp.conf)
I am getting no errors in /var/logs/apache2

Answer 1

1. How Apache is finding that "FlaskApp.conf"
There one line in /etc/apache2/apache2.conf to include virtual host configurations:
# Include the virtual host configurations:
IncludeOptional sites-enabled/*.conf
Apache2 server will load apache2.conf and also include the virtual host configurations.
2. Why Apache is showing its default webpage no matter what.
If you access the server via IP address, Apache will return based on its default site configuration in /etc/sites-available/000-default.conf. So if you want to access your WSGI server via IP address, you should disable the Apache default site configuration first:
sudo a2dissite 000-default.conf
service apache2 restart
