Engintron for cPanel/WHM is the easiest way to integrate Nginx on your cPanel/WHM server. Engintron will improve the performance & web serving capacity of your server, while reducing CPU/RAM load at the same time, by installing & configuring the popular Nginx webserver to act as a reverse caching proxy in front of Apache.
This is the last Engintron version to support EasyApache 3 as the latter is end-of-life as of December 2018 according to cPanel's related blog post.
