Running on Linux

1. Install JDK

Download and install Java 17 or a newer version.

2. Download the Server Core

Download the server core, for example, PAPER 1.20.4.

3. Configure Authlib Injector

1. Download authlib-injector
2. Place it in the server folder.

4. Start the Server

Create a file start.bat (for Windows) or start.sh (for Linux/MacOS) with the following content:

Windows (start.bat)

@echo off
java -Xmx4G -Xms4G -javaagent:authlib-injector-1.2.5-alpha-1.jar=https://localhost:5003/api/v1/integrations/authlib/minecraft -jar paper-1.20.4.jar nogui
pause

Linux/MacOS (start.sh)

#!/bin/bash
java -Xmx4G -Xms4G -javaagent:authlib-injector-1.2.5-alpha-1.jar=https://localhost:5003/api/v1/integrations/authlib/minecraft -jar paper-1.20.4.jar nogui

Make the script executable on Linux/MacOS:

chmod +x start.sh

Run the script. The server will start.

Important! Do not leave localhost:5003 if the server will be used by other players or deployed on a remote machine! In the -javaagent parameter, replace https://localhost:5003/api/v1/integrations/authlib/minecraft with the address of your API where the authlib injector integration is deployed.

If your server is available at https://api.example.com, the line should look like this:

-javaagent:libraries/authlib-injector-1.2.5-alpha-1.jar=https://api.example.com/api/v1/integrations/authlib/minecraft -Dauthlibinjector.debug
