Install Spring Boot applications

Make fully executable applications for Unix systems
A fully executable jar can be executed like any other executable binary or it can be registered with init.d or systemd
Gradle configuration:

bootJar {
  launchScript()
}

Installation as a systemd Service

create a script named myapp.service and place it in /etc/systemd/system directory

[Unit]
Description=myapp
After=syslog.target

[Service]
User=myapp
ExecStart=/var/myapp/myapp.jar
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

Remember to change the DescriptionUser, and ExecStart fields for your application.

To flag the application to start automatically on system boot, use the following command:

systemctl enable myapp.service
