screen -S Minecraft

Creating a Start Command
nano start.sh

Pase the following line into the nano.sh file. Replace minecraft.jar with the name of the JAR file that you uploaded
java -Xms1024M -Xmx1024M -jar minecraft.jar

You can also replace 1024 with the amount of RAM you want to allocate to your Minecraft server. This should be less than the total amount of RAM on your VPS
