Cannot connect to nginx server on fedora linux (digitalocean) - linux

Question

I tried to set up nginx on a brand new fedora box on DigitalOcean. These are my steps
$ yum install nginx
$ systemctl enable nginx
$ systemctl restart nginx
However, it doesn't seem to work. I get the following output when running systemctl status nginx
[root#inspiredev ~]# systemctl status nginx -l
nginx.service - The nginx HTTP and reverse proxy server

I can't seem to figure out or where I went wrong. It'd be great if someone can help with this.
EDIT: When I go to the box's IP address, I got nothing, which is why I feel like something is not working right.

From the systemd logs, nginx service appears to be running. (the warning about the pid file not found seems endemic to many distributions).
On fedora 19/20 (systemd based), open the firewall with the following commands:
firewall-cmd --permanent --zone=public --add-service=http
systemctl restart firewalld.service
or alternatively:
firewall-cmd --permanent --zone=public --add-port=80/tcp
systemctl restart firewalld.service
The second version syntax lets you open any port/protocol combination.
