Jellyfin From Scratch: How to Build a Complete Media Server on Linux Mint (Docker, Nginx, and Let’s Encrypt)
Start from a clean OS and end with your own secure, self-hosted streaming platform — complete with HTTPS access, remote streaming, and full media organization.
🧠 Introduction
Jellyfin is a free, open-source media server that lets you organize and stream your movies, shows, and music to any device. Think of it as your personal Netflix — except you control everything.
In this guide, you’ll start from a clean Linux Mint installation and finish with a fully working Jellyfin server running inside Docker, served securely through Nginx with Let’s Encrypt SSL certificates, protected by Fail2ban, and accessible anywhere through a DuckDNS domain.
This tutorial uses CPU-only transcoding (no GPU acceleration) and follows current Docker Compose v2 standards. This means, if want to use your GPU to do all the heave lifting, I ain't gunna show you that here but, you can still use this tutorial to get your server up and running then, configure your GPU later.
🧰 Prerequisites
- 
A clean install of Linux Mint (based on Ubuntu 20.04 or later)
 - 
Sudo privileges
 - 
An active internet connection
 - 
A DuckDNS account and domain (e.g.,
myserver.duckdns.org) - 
Some media files stored locally or on a mounted drive
 
🧱 Step 1 — System Preparation
Start by updating your system and installing a few required packages.
sudo apt update && sudo apt upgrade -y
sudo apt install -y ca-certificates curl gnupg lsb-release ufw fail2ban
Enable the firewall and allow only essential services: (run each line separately)
sudo ufw default deny incoming 
sudo ufw default allow outgoing 
sudo ufw allow OpenSSH 
sudo ufw allow 80,443/tcp 
sudo ufw enable
Check status:
You should see SSH, HTTP, and HTTPS allowed.
