Minecraft

Server Setup

This is a minecraft server based on PaperMC patches for performance and uses GeyserMC Spigot as a Bedrock proxy with GeyserMC Floodgate to bypass Java paid edition login.

• PaperMC: The most widely used, high-performance Minecraft server that aims to fix gameplay and mechanics inconsistencies.
• GeyserMC Spigot: Enable clients from Minecraft Bedrock Edition to join your Minecraft Java server.
• GeyserMC Floodgate: Allows Geyser players to join servers without needing to log into a paid Java Edition account.

Notes

• 2024-02-08: Rebuilt currently not using the geysermc proxy
  • Uses screen to lunch the server so you can attach to a running server using screen -x.
  • Simplified server options in the environment variable MINECRAFT_SERVER_OPTIONS for future use options where:

  -Xms1G -Xmx3G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=200 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dusing.aikars.flags=mcflags.emc.gs -Dcom.mojang.eula.agree=true
  

  • Another option that was in the old configs --nojline nogui
  • "Failed to get system info for Microarchitecture" warning seems to be related to PaperMC/Paper#9785
  • Testing the auto build
  • 2024-02-27: Possible backup strategy
