Setup Service as Daemon (Debian)

Systemd is now being used by many modern Linux distributions. To install a Spring Boot application as a systemd service, create a ‘Unit File’ named myapp.service and place it in /etc/systemd/system directory. The following ‘Unit file’ offers an example:

[Unit]
Description=myapp <-- Add your description here
After=syslog.target

[Service]
User=myapp <-- Add a valid user here. User MUST have access to jar file.
WorkingDirectory=/installation/path
ExecStart=/installation/path/'SERVICE'.jar <- jar file or shell script
SuccessExitStatus=143

[Install]
WantedBy=multi-user.target

---

NOTE

If a startup script is available, it is recommended that you use it, as it may contain some additional settings.

---

Note that, unlike when running as an init.d service, the user that runs the application, the PID file, and the console log file are managed by systemd itself and therefore must be configured by using appropriate fields in the ‘service’ script. Consult the service unit configuration man page for more details.

Manage Service

root@server:~# systemctl start|stop|restart myapp(.service)

Start Service at Startup

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

root@server:~# systemctl enable myapp(.service)
