STEP 1 – CREATE A NON-ROOT USER

$ adduser jellyfin

$ usermod -aG sudo jellyfin

STEP 2 – UPDATE YOUR SYSTEM
Close out of PuTTY and log back in as “jellyfin”

$ sudo apt update && sudo apt upgrade

Say YES to the install. If, during the installation process you’re asked about overwriting older config files, select N (default).  Once the update is 100% finished:

$ sudo reboot

Close out of PuTTY, give the server a minute or two to reboot, then use PuTTY to log back in as user “jellyfin”.

STEP 3 – HOUSEKEEPING AND FIREWALL SETUP

$ sudo apt-get install -y gnupg2 gnupg gnupg1

$ sudo ufw enable
$ sudo ufw allow 22
$ sudo ufw allow 8096
$ sudo ufw allow 443
$ sudo ufw allow 80

STEP 4 – INSTALL JELLYFIN

Install Jellyfin from the jellyfin.org website (see video)

Cut and paste each command from the jellyfin website into PuTTY.

Test your install by visiting www.yourjellfin.domain:8096

STEP 5 – SECURE YOUR SERVER

$ sudo ufw deny 8096

INSTALL CADDY

$ echo "deb [trusted=yes] https://apt.fury.io/caddy/ /" \
| sudo tee -a /etc/apt/sources.list.d/caddy-fury.list

$ sudo apt update
$ sudo apt install caddy
$ sudo service caddy stop

$ cd /etc/caddy
$ sudo nano Caddyfile

DELETE the default contents of this file and replace with:

https://your.domain.here {
       reverse_proxy 127.0.0.1:8096
}

**** syntax is very important in the caddyfile - check and recheck it.

CTRL-O to save the Caddyfile
CTRL-X to exit out of the text editor

$ sudo caddy start

Close PuTTY

Open a browser and access your server with www.yourjellfin.domain (no port).
