I've installed Nginx to my ubuntu machine. And by default, as I understood it should listen on port 80 and should be available by localhost in the browser address bar, but I mentioned that this port already occupied by Apache.

It returns me this page. My question is, how can I change this behavior and make Nginx listen on the localhost? What I've tried is to delete Apache, was thinking it will help, but it didn't.

I've used this command :

sudo apt-get purge apache2

What I've got in response is:
