Uninstall / Remove Apache

[mawan]

I only use Nginx, but why is Apache still active? Is it safe if I uninstall Apache? How to uninstall Apache via Control Panel?

Apache works as a main server and NGINX as a reverse proxy. So, you can't get the server running only with NGINX. So, don't install the apache or your server will be broken otherwise.
