If you plan to set up a server for multiplayer, please visit Releases page and download the file named GregTech.Odyssey-server.zip server modpack file. This file contains all the core components and configurations required to run the server, ensuring server stability and compatibility without manually assembling server files. After downloading, please follow the instructions to extract and configure the server files to ensure players can connect smoothly and enjoy multiplayer.

This modpack uses Minecraft1.20.1-forge as the server hosting tool. For your gameplay experience, we highly recommend using a Linux system to host and play. Compared with panel servers and Windows servers, Linux is suitable for multiplayer collaboration and can deliver a higher gaming experience with less memory. Therefore, below we will use hosting on a cloud server from a certain platform as an example to introduce how to quickly deploy and run this modpack on a Linux server.

Pre-Server Preparation

  • 1. A server/cloud server with a public IP, with 8G or more memory recommended

  • 2. Deploy a Linux system on the cloud platform (using CentOS9 as an example)

  • 3. Install an SSH client on your local machine for system management (using SecureCRT as an example)

  • 4. Friends who play with you

Server Startup Process

  • 1. After completing the preparations, remotely connect to the cloud server via the public IP using an SSH platform

  • 2. Upload the server-side files and extract them

  • 3. Run the startup script using a command

  • 4. Accept the agreement using the vim editor

  • 5. Run the startup script again, then close it after the configuration file is generated

  • 6. Modify the configuration file and run it again to complete server startup

Server Configuration

1. Vanilla server configuration (server.properties)

Recommended settings:

white-list=false

allow-flight=true

2. Claim and Team Configuration (world/serverconfig/openpartiesandclaims-default-player-config.toml)

Recommended setting: offlineForceload = true toEnable offline forced chunk loading

※ Enabling offline chunk force-loading will significantly affect server performance!!!

3. Memory Management

Please allocate JVM memory reasonably according to the server configuration, ensuring there is enough available memory to guarantee stable server operation

4. Game Difficulty Adjustment (config/gtocore.yaml)

If this is your first time playing Gray, I suggest playing easy mode. After the difficulty modification is complete,Need to delete the world and regenerate the worldOnly then will it take effect; please check the differences based on difficulty.Difficulty Characteristics Guide

5. Subsequent server update versions

Visit the Releases page and download the latest GregTech.Odyssey-server.zip server modpack. After extracting, copy your old server's world, ops.json, server.properties to the new server directory to complete the upgrade and keep your data
