How To Set Up A Private Minecraft Server

Minecraft is a popular multiplayer video game. Players can connect to a Minecraft server hosted within their running game or to a separate server hosting a Minecraft world.



Without Tailscale, setting up a Minecraft server to be reachable from outside the home means either:



- paying for third party hosting, or - opening ports in the firewall, potentially allowing access to any rando on the Internet



With Tailscale, you can share it from anywhere with just the people you want.



This guide will demonstrate how to set up a Minecraft server bedrock_server and connect from anywhere using Tailscale.



Prerequisite: a Linux server



You will need a server. These instructions assume a Linux server or VM running within the home, behind a firewall. Tailscale lets clients connect to computers wherever they are, so you do not need to worry about the accessibility of the machine. It just needs to be on the internet. If you sign up for a VM hosted by a cloud provider, please make sure to block almost all access in the firewall.



The instructions in this guide assume you are using Ubuntu or Debian, though the changes for other Linux distributions are small.



Step 1: Set up bedrock_server on Linux



The bedrock_server supports both Windows and Linux. We'll cover Linux in this guide.



We recommend creating a user to run the Minecraft server, and installing some packages we'll need later:



Download the current version of the Linux bedrock_server binary from https://www.minecraft.net/en-us/download/server/bedrock. It is best to do this as the minecraft user just created:



Minecraft bedrock_server is updated relatively frequently, and when the Minecraft game app is updated it requires the new version of the server. So we'll prepare for future updates by storing the server files in git:



Each successive bedrock_server update can be stored in git. Pay special attention to permissions.json and server.properties, where any future bedrock_server will overwrite any customizations you may have made.



systemd



systemd is a way to automatically start services when the system boots. We'll create a few files to have bedrock_server start automatically.



/etc/systemd/system/minecraft.service



/opt/minecraft/start.sh



/opt/minecraft/stop.sh



Also make the shell scripts executable: chmod +x /opt/minecraft/start.sh /opt/minecraft/stop.sh



As root you should now systemctl start minecraft and voila, you are running a Minecraft bedrock edition server.



As the minecraft user, you can connect to tmux to see the server console:



To detach from tmux and leave bedrock_server running, press Ctrl-B then "d" for detach.



Step 2: Install Tailscale on the server



Tailscale is available for essentially any modern Linux distribution, though the installation instructions may vary slightly.



Download Tailscale



Once installed and active on the tailnet, the Minecraft bedrock_server can be reached from any of your other Tailscale clients.



Step 3: Play Minecraft



You'll need the Tailscale client installed, from the App Store for iOS devices and the Play Store for Android. You'll also need the Minecraft app.
Minecraft servers


In the Minecraft app, select "Play" then the "Servers" tab. There will be a number of promoted third-party servers in the list, but scrolling to the bottom there will be a button to "Add Server"



Add the details of the server just created, including the Tailscale IP address (the 100.x.y.z IP address, which can be looked up in the Tailscale app or in the admin console for your network)



You'll be asked to login to XBox Live before being allowed to connect to the server. live.com accounts are free, and you don't have to have an XBox to create one. Tailscale never receives the live.com account, Minecraft simply requires it before connecting.
