Quick setup of nginx/ssl under Debian 9.5

Install following packages:

apt-get install nginx ssl-cert

The nginx should be now listening on port :80 so pointing your browser to url http://IP_OF_YOUR_SERVER should work.

Enabling ssl with self signed cert

I think that it is good way to try self-signed cert (installed byt ssl-cert package) before going to Let's encrypt etc...

To enable ssl you need to uncomment following lines in /etc/nginx/sites-available/default:

     listen 443 ssl default_server;
     listen [::]:443 ssl default_server;
     include snippets/snakeoil.conf;

And restart nginx using:

systemctl restart nginx

Your nginx should be now available at https://YOUR_SERVER_IP. Most browser will (of course) show warning that certificate is self-signed, but it is OK for testing.
