How to Set Up a Minecraft Java Server (and Add Datapacks)

Running your own server lets you and your friends share a persistent world and play datapack minigames together. It sounds intimidating but the basics are straightforward. This is a conceptual walkthrough for Java Edition — exact steps vary by host and operating system, and you should always follow Mojang's EULA.

Vanilla vs. Paper vs. a host

The official 'vanilla' server software from Minecraft.net runs the game exactly as designed and supports datapacks fully — perfect if you want pure, unmodified play. Community server software like Paper is a drop-in replacement that's far more performant and adds plugin support, while still running your datapacks. If you'd rather not manage a machine at all, a paid hosting provider gives you a control panel and a public address with no command line.

• ▸Vanilla — official, simplest, full datapack support.
• ▸Paper — faster, plugin-capable, still runs datapacks.
• ▸Hosting provider — no setup or port-forwarding; a monthly fee.

The first-run checklist

• ▸Install Java (the server needs a current Java runtime).
• ▸Put the server .jar in its own folder and run it once to generate files.
• ▸Open eula.txt and set eula=true to accept Mojang's terms.
• ▸Edit server.properties — set the gamemode, difficulty, and whether the world is new.
• ▸Start it again; the world generates and the server is live on your local network.
• ▸To let outside friends join, either forward the port on your router or use a hosting provider that handles it.

Adding datapacks to a server

Server datapacks live in the same place as single-player ones: inside the world folder, in a 'datapacks' directory. Stop the server (or run /reload), drop your .zip into world/datapacks, start back up, and run /datapack list to confirm. Because datapacks are server-side, none of your players need to install anything — they just join and play. That's a big part of why datapack minigames are so easy to share.

Keeping it healthy

Back up your world folder regularly, keep the server and your datapacks on matching Minecraft versions, and re-test packs after any update — a pack_format change is the usual reason something breaks. Start small, get one minigame running for friends, and grow from there.
