SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Setting up a modded Minecraft server involves many error-prone manual steps: installing the correct Java version, running the NeoForge/Forge installer, tuning JVM garbage collection flags, configuring server.properties for modded gameplay, and setting up backups. This Skill walks through the entire process with tested defaults. ## Core Features & Use Cases - End-to-End Server Setup: Downloads a server pack zip, installs the matching Java version, runs the mod loader installer, accepts the EULA, and generates a clean launch script. - Performance Tuning: Provides JVM arguments (G1GC flags) and view/simulation distance presets scaled to mod count, player count, and available RAM. - Automated Backups: Creates a cron-scheduled backup script that archives the world folder hourly and prunes old backups. - Use Case: A user downloads an All The Mods 10 server pack and wants to host it for friends on a Linux machine. The Skill installs Java 21, runs the installer with ATM10_INSTALL_ONLY, configures server.properties for modded play, and sets up hourly world backups. ## Quick Start Set up a modded Minecraft server on this machine from the server pack zip at this URL, with 12GB of RAM and hourly backups.

Frequently Asked Questions about minecraft-modpack-server

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up a modded Minecraft server from a CurseForge server pack?▼

Download the server pack zip, extract it, and run its included install script (for example with ATM10_INSTALL_ONLY=true) to install the NeoForge or Forge loader. Then accept the EULA, configure server.properties, and launch with the pack's unix_args.txt file.

Which Java version do I need for a modded Minecraft server?▼

Minecraft 1.21 and newer requires Java 21, versions 1.18 through 1.20 require Java 17, and 1.16 or older requires Java 8. Check the server pack's start script to confirm the required version before installing.

How much RAM should I allocate to a modded Minecraft server?▼

Allocate 6-12GB for packs with 100-200 mods and 12-24GB for packs with 200-350+ mods. Always leave at least 8GB free for the operating system and other tasks.

Why do players get kicked for flying on a modded Minecraft server?▼

Modded servers kick players because allow-flight defaults to false while mods add jetpacks and flying mounts. Set allow-flight=true in server.properties to prevent these kicks.

Why is my modded Minecraft server slow to start the first time?▼

First startup takes several minutes because large packs generate chunks and initialize hundreds of mods. 'Can't keep up!' warnings during initial world generation are normal and settle afterward.

How do I run a Minecraft server for players without Mojang accounts?▼

Set online-mode=false in server.properties for LAN or offline play, and also set enforce-secure-profile=false or clients will be rejected. This disables Mojang authentication.
