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 commands and modded-specific settings. ## Core Features & Use Cases - Guided Server Pack Installation: Download, unzip, and install CurseForge/Modrinth server packs with the correct Java version (8, 17, or 21) matched to the Minecraft version. - Modded-Specific Configuration: Applies critical settings like allow-flight=true, max-tick-time=180000, and online-mode/enforce-secure-profile pairing that modded servers require. - Performance Tuning & Backups: Provides G1GC JVM arguments scaled to mod count and RAM, view-distance presets by player count, plus a cron-based world backup script with rotation. - Use Case: A user downloads an All The Mods 10 server pack and wants to host it for friends. The Skill installs Java 21, runs the installer with ATM10_INSTALL_ONLY, tunes 12-24GB JVM args, opens the firewall, and schedules hourly world backups. ## Quick Start Set up a modded Minecraft server on my Linux machine from this server pack zip URL and configure it for 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 CurseForge server pack?▼

Download the server pack zip, unzip it, and run its 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 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. Install the headless OpenJDK package matching your modpack's Minecraft version and verify with java -version.

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 pair the allocation with G1GC tuning flags in user_jvm_args.txt.

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

Vanilla flight detection kicks players using modded jetpacks or flight items. Set allow-flight=true in server.properties, which is required for virtually all modded servers to prevent false-positive kicks.

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 to the server.

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

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