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 arranging backups. This Skill walks through the entire process with tested defaults. ## Core Features & Use Cases - End-to-End Server Setup: Download a server pack zip, install the matching Java version, run the mod loader installer, accept the EULA, and generate a clean launch script. - Performance Tuning: Provides JVM G1GC arguments and view-distance/simulation-distance presets 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 archives. - Use Case: A user downloads an All The Mods 10 server pack and wants it running on a Linux VPS for six friends. The Skill installs Java 21, runs the installer with ATM10_INSTALL_ONLY, configures server.properties with allow-flight and extended tick timeouts, opens the firewall, and schedules hourly backups. ## Quick Start Set up a modded Minecraft server on this machine from my CurseForge server pack zip and configure it for six players with automated 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 and unzip the server pack, install the Java version matching your Minecraft release, run the included installer script or 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. Verify the installed version with java -version before starting the server.

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 processes.

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

The vanilla server kicks players it detects as flying, which conflicts with modded jetpacks and flight items. Set allow-flight=true in server.properties to prevent these false-positive kicks.

Why is the first startup of a modpack server so slow?▼

Large modpacks take several minutes on first launch due to initial chunk generation and mod loading. "Can't keep up!" warnings during this phase are normal and settle after worldgen completes.

Can I run a Minecraft server without Mojang authentication for LAN play?▼

Yes, set online-mode=false in server.properties for LAN or offline play. You must also set enforce-secure-profile=false, otherwise clients will be rejected when connecting.
