Step-by-Step Configuration Guide

Download Java Runtime

Install Java JDK 17 (or JDK 21 for version 1.20.5+). Verify installation in Command Prompt using 'java -version'. Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Download Server Binaries

Download the PaperMC jar file and place it inside a clean folder (e.g., C:/MinecraftServer). Make sure to select the build version that matches your game server software exactly to prevent class loading errors during startup.

Accept EULA terms

Create a run.bat file, run it once to generate files, open eula.txt, set eula=true, and save the file. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Setup Router Port Forward

Access your router dashboard, create a virtual server rule for port 25565 (TCP/UDP), and forward it to your computer's local IP address. This step is critical for proper server operation. Ensure that you have taken a manual file backup before committing these changes to disk.

Recommended Configurations and Setup Files

To configure your server files correctly, navigate to the File Manager in your control panel and open the corresponding configuration files. Paste or modify the settings as shown in the configuration block below. These lines help prevent database thread blockages, optimize tick timing performance, and reduce entity rendering overhead on the game host:

# Create run.bat startup script: @echo off java -Xms4G -Xmx4G -jar paper.jar nogui pause

Pro Tip: Self-hosting exposes your public IP. To protect your home network from script kiddies and DDoS attacks, consider using a secure, free cloud server like FreeGameHost.
