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 flags, editing server.properties, opening firewall ports, and configuring backups. This Skill walks through the entire process with tested commands and modded-specific settings. ## 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 launch the server. - Performance Tuning: Provides JVM garbage collection flags and view-distance/simulation-distance presets scaled to player count, mod 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 a working server for five friends. 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 hourly backups and settings for six players.

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 the server pack zip, extract it, install the Java version matching your Minecraft release, then run the pack's installer script or the Forge installer jar. Accept the EULA, configure server.properties, and launch with the provided JVM 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 requires Java 8. Install the matching headless OpenJDK package and verify 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 set Xms and Xmx in user_jvm_args.txt.

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

Vanilla servers kick players who appear to fly, which conflicts with modded jetpacks and flight items. Set allow-flight=true in server.properties to prevent these false kicks on modded servers.

Why do clients get rejected when online-mode is false?▼

When online-mode is disabled, you must also set enforce-secure-profile=false in server.properties. Otherwise clients without Mojang authentication are rejected during the handshake even though online-mode is off.

How do I automate Minecraft world backups with cron?▼

Create a bash script that tars the world folder into a timestamped archive and prunes backups beyond a retention limit. Register it with crontab on an hourly schedule and log output to a backup log file.
