Registering Spring Boot .jar as Auto-Start Service on AWS EC2: Quick Guide

This article discusses how to resolve the situation where an AWS EC2 server frequently shuts down, necessitating the setup of automatic restart on Ubuntu 20.04. It offers a straightforward method that can be applied immediately without the need for complex .sh files.

Creating the server_start.service File

Create a server_start.service file in the /etc/systemd/ directory and write it as follows:

[Unit]
Description=server start
After=mysql.service

[Service]
ExecStart=/bin/bash -c "exec java -jar /home/ubuntu/my-0.0.1-SNAPSHOT.jar"

[Install]
WantedBy=multi-user.target

The ExecStart=/bin/bash -c "exec java -jar /home/ubuntu/my-0.0.1-SNAPSHOT.jar" section is crucial for immediately executing the command when the service starts.

Checking Service Operation

You can verify if the created service is functioning correctly with the following commands:

sudo systemctl daemon-reload
sudo systemctl start server_start.service
sudo systemctl status server_start.service

Confirmation of Proper Operation After Reboot

To confirm that the service operates correctly even after a reboot, simply execute sudo reboot, and after the reboot, check if the .jar process is running.
