How to make a jar file run on startup

run-jar-as-a-service.md

1. Create the start and stop scripts of your application.

• Example:

myapp-start.sh

#!/bin/bash
cd /home/ubuntu/myapp/
java -jar myapp.jar --server.port=8888 &

myapp-stop.sh

#!/bin/bash
sudo fuser 8888/tcp -k || true

2. Create a file named myapp inside /etc/init.d/

#!/bin/bash

case $1 in
    start)
        /bin/bash /home/ubuntu/scripts/myapp-start.sh
    ;;
    stop)
        /bin/bash /home/ubuntu/scripts/myapp-stop.sh  
    ;;
    restart)
        /bin/bash /home/ubuntu/scripts/myapp-stop.sh
        /bin/bash /home/ubuntu/scripts/myapp-start.sh
    ;;
esac
exit 0

3. Mark myapp as executable:

cd /etc/init.d/
sudo chmod +x myapp 

4. Make the script start on boot:

sudo update-rc.d myapp defaults 

On Ubuntu 16.04 and above it will give a warning "insserv: warning: script missing LSB tags and override" but I am not sure if the warning can prevent it from running
