Hmmm, as I understand it both Apache and Nginx are running. I just found this at the ServerPilot website.
ServerPilot configures a LAMP/LEMP stack on your server. LAMP stands for Linux + Apache + MySQL + PHP. As ServerPilot also configures Nginx on your server, this is sometimes called a LEMP stack because Nginx is pronounced "Engine X."ServerPilot configures Nginx as the public-facing web server because it is much more scalable than Apache. Unlike Apache, Nginx can handle handle tens of thousands of simultaneous client connections. As Nginx waits until it has completely received the request before proxying the request through to Apache, your server is safe from Slowloris attacks. For your SSL-enabled apps, Nginx also provides extremely efficient SSL handling as well as SPDY support.
I’ll take a look at the information you posted, much appreciated, I have a lot to learn still !!
