Install Apache using your package manager with the following command:

sudo apt-get install apache2 

Confirm Apache is working by visiting the public IP of the instance in your browser. You should see the apache page:

When Apache receives a request it has a number of ways it can respond. What you’ve seen thus far is the simplest method of operation, Apache just returns a file requested or the index.html file if no file is defined within the URL.

But, Apache can do so much more! You’ll now configure Apache to hand-off certain requests to an application handler - mod_wsgi.

To install mod_wsgi user the below command:

$ sudo apt-get install libapache2-mod-wsgi
