Download minecraft server .jar file from

https://www.minecraft.net/en-us/download/server/

At the time of writing, i downloaded

wget https://launcher.mojang.com/v1/objects/3dc3d84a581f14691199cf6831b71ed1296a9fdf/server.jar

Don’t use above link as it can get older, always go to minecraft site and get new link, so you get latest minecraft server jar file.

You can start minecraft server with command

java -Xmx1024M -Xms1024M -jar server.jar nogui

First time when you run, it exit with some error related to EULA.

You need to edit file

vi eula.txt

eula=true

Now minecraft will run. You can create a run.sh file with following command for starting minecrat easily.

vi ~/start.sh

Paste following content

#!/bin/bash

java -Xmx1024M -Xms1024M -jar server.jar nogui

To make the file executable, chmod it 755

chmod 755 ~/start.sh

When you start minecraft from terminal/ssh, it get closed when you disconnect. To keep minecraft server running after you disconnect, use tmux or screen.
