Minecraft Server | shira.at


This is a reminder on how to quickly install a 1.18.2 vanilla minecraft server. Im forgetful and this could also help others.

Why paper?
Paper is an optimized minecraft server that works with default minecraft clients and also supports bukkit and paper plugins.

Install Java17

To find the newest version of jdk17 you can find it here: https://adoptium.net/de/temurin/releases/.

To quickly download it use the following command on your server:

wget https://github.com/adoptium/temurin17-binaries/releases/download/jdk-17.0.3%2B7/OpenJDK17U-jdk_x64_linux_hotspot_17.0.3_7.tar.gz

To “unzip” it run the following

tar -xvf OpenJDK17U-jdk_x64_linux_hotspot_17.0.3_7.tar.gz
mv jdk-17.0.3+7/ jdk17

Then add it to your path

echo -e "\nexport PATH=$PATH:/home/papier/jdk17/bin" >> .bashrc

Now either relog into your server or run the following to reload the .bashrc file

. .bashrc

And verify that it works with

java -version

Install minecraft server

To download it on your server run

wget https://api.papermc.io/v2/projects/paper/versions/1.18.2/builds/379/downloads/paper-1.18.2-379.jar -O paper.jar

For the newest version of minecraft visit https://papermc.io/downloads , right-click on the blue “#999” version number and select “copy link”. Then replace the link in the command above to download the newest version.

To now run the server for the first time

java -jar paper.jar

It wil then tell you to change false to true in the eula.txt to accept it. To quickly do that run the following

sed -i 's/false/true/g' eula.txt

Now you can run your minecraft server again with

java -jar paper.jar

Setup minecraft background process

My minecraft server never crashed so I simply ran it within a screen.

To setup simple commands that can start, stop and fix your minecraft server run the following command:

curl https://raw.githubusercontent.com/OverlordAkise/simple-minecraft-server/main/bash_aliases.txt >> .bash_aliases
. .bash_aliases

Now you can use the command


To start your minecraft server in a background process. To see all the mc* commands simply enter mc and press the TAB key twice.

Automatic Backups

For automatically backuping up your world you need to create 2 cronjobs: One to backup your world and one to delete backups older then X days.

First create a backup folder with

mkdir ~/backups

To edit your cronjobs run the following. (If you get asked about an editor take nano, which is probably the first one)

crontab -e

And then add the following 2 lines at the bottom:

02 3 * * * cd $HOME && zip -r9 $HOME/backups/worlds_$(date +\%Y\%m\%d\%H\%M\%S).zip world world_nether world_the_end
02 4 * * * find $HOME/backups/* -mtime +7 -exec rm {} \;

To exit press CTRL+X, then Y and then ENTER.

Now your minecraft world gets automatically backed up every day at 3:02am.
