MC Eternal 2 Minecraft server setup

MC Eternal 2 is a "kitchen sink" Forge modpack for Minecraft 1.20.1. The project page says it mixes hundreds of quests with Create factories, Mekanism, spellcasting mods, MineColonies towns, bosses and a custom mining dimension called The Great Below. This guide installs it from the Modpacks tab and covers how players join.

Checked against MC Eternal 2 1.3 (Minecraft 1.20.1, Forge), October 2026.

What it needs

• Forge on Minecraft 1.20.1. The newest file on CurseForge is MC Eternal 2-1.3. It has a separate server pack, [MCE2]-Server-Pack-1.3.zip, which the Modpacks tab installs for you. It is a large download, about 1.5 GB.
• Java 17. The panel picks Java from the Minecraft version, and 1.20.1 gets Java 17.
• RAM. The author's own server files set the Java heap to between 4 GB and 8 GB. The pack page suggests players have at least 16 GB in their computer, with 8 to 10 GB given to the game. Choose a plan with 8 GB of RAM or more, the top of the author's range, on Minecraft hosting.
• Free disk space. The zip downloads onto your server's disk before it is unpacked, and it is big, so keep plenty of room for the zip and then the unpacked pack.
• The right pack. The same author also publishes MC Eternal and MC Eternal Lite, which are separate packs. Pick MC Eternal 2.

Install it on your server

Choose the CurseForge chip on the Modpacks tab, search for MC Eternal 2 and pick the row by adam98991 named exactly MC Eternal 2. Click Install: the window is titled Install MC Eternal 2?. Allow time for the download and for Forge to install. The version list, the backup, the EULA box and the progress bar are covered in Install a CurseForge modpack.

The server pack keeps everything inside one folder and brings its own Forge installer. The installer in this pack is for Forge 47.4.2. The panel unpacks the folder to the server's root and runs that installer for you, so you do not run the pack's run.bat or follow its readme steps.

The panel writes its own start script and sizes the Java heap from your plan's RAM. The memory numbers in the pack's own files are not used.

Join the server

1. In the CurseForge app, install MC Eternal 2. Version 1.3 is the newest on its page.
2. Add your server in the multiplayer list with the address in the left rail. Connect to your server for the first time shows where it is.

Use Operators in the Players tab to give yourself commands (Whitelist players and set operators).

Updating later

When the author publishes a newer file for your server's Minecraft version, the pack's card on the Modpacks tab shows Update to with that version. It only offers a file newer than the one installed, on the same Minecraft version and loader. Press it: the window that opens has that file already picked in its version dropdown, Keep my world, settings and player lists ticked, and holding Update and reinstall installs the new version. Leave Take a backup first ticked. With nothing newer out, the card reads Up to date. A pack installed before the panel update of 27 October 2026 with Newest that fits your server shows neither, because the panel did not record which file it took. To update one of those, take a backup, press Remove modpack, then install the new version.

The pack's readme adds one step after an update: delete the serverconfig folder inside your world folder, because leaving it can stop some changes from applying. Open File Manager, open the world folder, and delete serverconfig.

Common problems

• The console says no CurseForge server pack is available. Check you picked MC Eternal 2, not MC Eternal or MC Eternal Lite.
• The server runs out of memory. Check the RAM Usage card, and see Why is my server lagging.
