nginx down in whm status

Getting notifications from WHM:

I installed this on a new cpanel server using below method:

Code:

wget http://nginxcp.com/latest/nginxadmin.tar
tar xf nginxadmin.tar
cd publicnginx
./nginxinstaller install

Does this technically install nginx server itself, or just an admin panel?

How do I fix the downed service? In nginxcp admin panel, it shows up and running, green. But in server status in WHM, shows down.

Can someone please recommend a good configuration for a shared / reseller hosting environment? I'm running with these specs:

Dual Hexcore Xeon
32GB RAM
SSD Drives
Apache 2.4, PHP 5.6, Cloudlinux + Cagefs, suPHP

I found these online:
