We need a webserver able to feed pages via TLS/SSL to our WebRTC browser clients. Whatever webserver that's able to speak HTTPS will do. The two most popular webserver at the moment are Apache and NginX. Let's look at how to install them and enable HTTPS/SSL, on Debian 8 (Jessie).

We will then be ready to put the files we want to serve via HTTPS in the directory /var/www/html/, both in Apache and NginX case.

You only need Apache or NginX, no need to install both of them.
