Nginx is an apache alternative but on cPanel we are going to be using nginx as a proxy to minimize server load and speed up your websites.
Log into your server via SSH as root user
cd / rm -f engintron.sh wget --no-check-certificate https://raw.githubusercontent.com/engintron/engintron/master/engintron.sh bash engintron.sh install
Or you can use this one line
cd /; rm -f engintron.sh; wget --no-check-certificate https://raw.githubusercontent.com/engintron/engintron/master/engintron.sh; bash engintron.sh install
I believe this is by far the best method/plugin for cPanel servers.
