AWS EC2 Amazon Linux 2 How To Run Java on Boot

Question

I've been looking all over the internet for a solution for this one and I just can't seem to get it right.

I have a command that I would like to start when my AWS EC2 server boots.

java -Xmx1740M -Xms1740M -jar /home/ec2-user/server.jar nogui

I've tried the "Change User Data" setting and bash scripts but to no avail.

Answer 1

Turns out I was misreading what to paste into the user data
