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 and common pitfalls. ## 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 and prunes old backups. - Use Case: A user downloads the ATM10 server pack and asks the agent to set it up on a Linux machine for 6 players — the agent gathers preferences, installs Java 21, configures the server, opens the firewall, and schedules hourly backups. ## Quick Start Set up a modded Minecraft server from this server pack zip on my Linux machine for about 6 players with 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 server pack?▼

Download and unzip the server pack, install the Java version matching your Minecraft release, run the pack's installer script (or the Forge installer jar), accept the EULA, then configure server.properties and launch with the generated args file.

Which Java version does my Minecraft server need?▼

Minecraft 1.21 and newer requires Java 21, versions 1.18 through 1.20 require Java 17, and 1.16 or older runs on Java 8. Check the 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 to avoid memory pressure.

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

Vanilla server.properties disables flight by default, which kicks players using modded jetpacks or flying mounts. Set allow-flight=true in server.properties to fix this on any modded server.

Why does my modded server show 'Can't keep up' warnings?▼

These warnings are normal during first launch while chunks generate, and they settle afterward. Raising max-tick-time to 180000 prevents the watchdog from killing the server during long modded ticks.

How do I automate backups for a Minecraft server world?▼

Create a script that compresses the world folder into a timestamped tar.gz archive and prunes old backups beyond a retention limit. Schedule it with cron, for example hourly, and log output to a backup log file.
