Python – Apache not serving the python app

apache-2.2deploymentdjangomod-wsgipython

So here's my apache config:

LoadModule wsgi_module /usr/lib/apache2/modules/mod_wsgi.so

<VirtualHost *:80>
        ServerAdmin marijus.merkevicius@gmail.com
        ServerName 31.220.49.197
        WSGIDaemonProcess ts threads=25
        WSGIProcessGroup ts
        Alias /static /home/email-validator/static
        WSGIScriptAlias / /home/email-validator/index.wsgi

        # Set access permission
        <Directory />
                Allow from all
                Require all granted
        </Directory>

</VirtualHost>

Here's my index.wsgi:

import os
import sys
import site

# Add the app's directory to the PYTHONPATH
sys.path.append('/home/email-validator')
sys.path.append('/home/email-validator/email_validator')

os.environ['DJANGO_SETTINGS_MODULE'] = 'email_validator.settings'
os.environ['PYTHON_EGG_CACHE'] = '/tmp'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

EDIT:
apache error.log

When I go to http://31.220.49.197 apache doesn't serve me django app. When I do service apache2 restart everything goes okay What am I doing wrong ? This configuration works on my other applications.

I was facing same problem but fortunately after digging into the apache settings I was able to resolve this.

Here is my apache configure file i.e 000-default.conf which serves default page instead of my app. Note*: Examples are being shown below with the help of OP apache configuration.

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerAdmin webmaster@localhost
    DocumentRoot /var/www/html

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # For most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>
<VirtualHost *:80>
    ServerAdmin marijus.merkevicius@gmail.com
    ServerName 31.220.49.197
    WSGIDaemonProcess ts threads=25
    WSGIProcessGroup ts
    Alias /static /home/email-validator/static
    WSGIScriptAlias / /home/email-validator/index.wsgi

    # Set access permission
    <Directory />
            Allow from all
            Require all granted
    </Directory>

</VirtualHost>

And after commenting out default virtualhost setting at port 80 resolves my problem though we are still getting same error logs :) .

that means commenting out or removing entire default/first <VirtualHost *:80> section will resolve problem.

I am currently having Ubuntu 14.4 and this problem aroused after upgrading from 12.4.
