1. Install Jellyfin on your server

To simplify deployment and help automate this for as many users as possible, we provide a BASH script to handle repo installation as well as installing Jellyfin. All you need to do is run this command on your system

 wget -O- https://repo.jellyfin.org/install-debuntu.sh | sudo bash

 

2. SSL certificate generation:

sudo apt install nginx certbot python3-certbot-nginx

sudo certbot --nginx --agree-tos --redirect --hsts --staple-ocsp --email YOUR_EMAIL -d DOMAIN_NAME

echo "0 0 * * *  root  certbot renew --quiet --no-self-upgrade --post-hook 'systemctl reload nginx'" | sudo tee -a /etc/cron.d/renew_certbot

 

3. Configure nginx from a subdomain

Create a file named jellyfin.conf.

cd /etc/nginx/conf.d/
nano jellyfin.conf

Then, insert the following text, replacing DOMAIN_NAME with your domain.

# Uncomment the commented sections after you have acquired a SSL Certificate
server {
	listen 80;
	listen [::]:80;
	server_name DOMAIN_NAME;

	# Uncomment to redirect HTTP to HTTPS
	return 301 https://$host$request_uri;
}

server {
	listen 443 ssl http2;
	listen [::]:443 ssl http2;
	server_name DOMAIN_NAME;

	## The default `client_max_body_size` is 1M, this might not be enough for some posters, etc.
	client_max_body_size 20M;

	# use a variable to store the upstream proxy
	# in this example we are using a hostname which is resolved via DNS
	# (if you aren't using DNS remove the resolver line and change the variable to point to an IP address e.g `set $jellyfin 127.0.0.1`)
	set $jellyfin 127.0.0.1;
	resolver 127.0.0.1 valid=30;
