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 Forge or NeoForge installer, tuning JVM garbage collection flags, editing server.properties, opening firewall ports, and configuring backups. This Skill walks through the entire process with tested defaults and common pitfalls. ## Core Features & Use Cases - Server Pack Installation: Downloads and inspects CurseForge/Modrinth server pack zips, detects the mod loader type, and runs the installer without launching the server. - Performance Tuning: Provides JVM arguments (G1GC flags) and view/simulation distance settings scaled to mod count, player count, and available RAM. - Automated Backups: Creates a cron-scheduled tar.gz world backup script with automatic pruning of old backups. - Use Case: A user downloads the ATM10 server pack and wants a server for 5 friends. The Skill installs Java 21, runs the NeoForge installer, configures server.properties with allow-flight and extended tick timeout, allocates 12-24GB RAM, opens port 25565, and sets up hourly world backups. ## Quick Start Set up a modded Minecraft server from this server pack zip, ask me for my preferences on difficulty, player count, and RAM, then configure everything including 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 the included startserver.sh with the install-only environment variable, or run the Forge installer jar with --installServer. Then accept the EULA, configure server.properties, and launch with the generated args 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 or more mods. Always leave at least 8GB free for the operating system and other tasks.

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

Modded servers must set allow-flight=true in server.properties because mods with jetpacks, mounts, or flight items trigger the vanilla anti-flight check. Without this setting, players using flight mods are automatically kicked.

Why is my modded server slow or unresponsive on first startup?▼

First startup of a large modpack takes several minutes due to initial world generation and mod loading. 'Can't keep up!' warnings are normal during this phase and settle after initial chunk generation completes.

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

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