Minecraft server on Debian/Ubuntu, the minimalist (and right*) way | *Does not cover pubkey-only auth

debmc.md

Basic security setup

• Log in as root (default configured)
• Run apt-get update && apt-get dist-upgrade
• Create a user named minecraft with adduser minecraft, and skip everything except the password
• Run usermod -a -G sudo minecraft
• Log off, and log back in with the minecraft account
• Run sudo passwd -dl root
• Disable root login via SSH by running sudo sed -i -e "s/PermitRootLogin yes/PermitRootLogin no/g" /etc/ssh/sshd_config && sudo service ssh restart

Running your server

• Run sudo apt-get install openjdk-7-jdk tmux
• Start a new tmux session by running tmux
• Run mkdir mcserver
• Use wget to get your server JAR.
  • wget http://ci.md-5.net/job/spigot/lastSuccessfulBuild/artifact/Spigot-Server/target/spigot.jar for Spigot
  • wget http://www.minecraft.net/download/minecraft_server.jar for Vanilla
  • Or, copy the URL for your specific server JAR (e.g. CraftBukkit) and place it after wget
• Run java -Xmx512M -jar <server JAR name> to start your server
• To detach, do Ctrl+B-D(press Ctrl+B, and then hit D)
• To reattach, run tmux attach
• To update your server JAR, just wget -N <URL> in the mcserver directory.
