Nginx page displaying instead of home page

Whenever I enter the IP address of my site, I get this page:

---

Welcome to nginx!

If you see this page, the nginx web server is successfully installed and working. Further configuration is required.

For online documentation and support please refer to nginx.org. Commercial support is available at nginx.com.

Thank you for using nginx.

I have searched for answers, but have not found anything that works for me. I am running Ubuntu LEMP on 14.04, and used the one-click installation. The only thing I have done so far is to add a folder in the main directory, and call it “public.” This is where I will put my folders/pages etc.

Because of this change, I would like to set up the “public” folder as the root folder of my site, so that it will look there for an “index.***” page when displaying to a user. I changed the “etc/nginx/available-sites/default.conf” file to hopefully accomodate this:

---

server {
	listen 80 default_server;
	listen [::]:80 default_server ipv6only=on;

	root /public/;
	index index.php index.html index.htm;

	# Make site accessible from http://localhost/
	server_name localhost unaviamedia.ca;

	location / {
		# First attempt to serve request as file, then
		# as directory, then fall back to displaying a 404.
		try_files $uri $uri/ =404;
		# Uncomment to enable naxsi on this location
		# include /etc/nginx/naxsi.rules
	}

	error_page 404 /404.html;
	error_page 500 502 503 504 /50x.html;
	location = /50x.html {
		root /usr/share/nginx/html;
	}

	location ~ \.php$ {
		try_files $uri =404;
		fastcgi_split_path_info ^(.+\.php)(/.+)$;
		fastcgi_pass unix:/var/run/php5-fpm.sock;
		fastcgi_index index.php;
		include fastcgi_params;
	}

    .........

}

However, I am still only getting the Nginx welcome page when I access my site by IP, and it is getting annoying. How can I show the home page?

Let me know if I need to add anything else. Thanks!
