Before installing
- Start from a clean Fabric server on the pack’s Minecraft version: 1.21.1 for Adrenaline and SkyBlock Plus, 1.21.4 for AsguhoServer. The installer never changes your Minecraft version for you.
- Use at least 4 GB of RAM, and more if the pack’s card recommends it.
- Remove unrelated mods first. A pack will not install over mods it does not manage, and packs cannot be mixed.
- Make sure one backup slot is free. The installer creates a full backup before it changes anything; delete or download an old backup if all slots are used.
- If you are a subuser, you need file and backup permissions from the server owner.
Install in one action
- In the panel, open your server and select Modpacks.
- Choose the pack and select Install modpack.
- The installer verifies every download, creates the backup, installs the pack’s server mods and configuration, keeps your existing world and starts the server.
- SkyBlock Plus asks you to confirm, then starts a separate runic-skyblock world. Your previous world folder is kept.
- Watch Console until the server finishes loading, then join with the same modpack installed on your game client.
ImportantThese three packs are tested releases, not a general installer for every Modrinth or CurseForge modpack. Individual mods and plugins stay under Mods & Plugins.
Players cannot join
Each player needs the same modpack version on their client; client-only files are left out of the server install. Use the pack’s own launcher, such as CurseForge or Modrinth, to install the matching version.
Undo or recover
If the server will not start after a pack install, restore the backup the installer created from Backups. It contains your server exactly as it was before the install.
Running the installer again on a server that already has the pack verifies every file it manages.
Updates
Do not blindly auto-update a modded server. A new pack build can change loader requirements, configuration, world generation or dependencies. Create a backup and check the pack’s changelog first.
