Environment Configuration

We use Fedora 38 Workstation, but the following steps should be similar on other systems.

We also use a timer to delay the startup of jetty11 at bootup, because it sometimes struggles to perform well at the first start.

vim /lib/systemd/system/jetty11.timer

[Unit]
Description=Timer for jetty11 Startup Delay
 
[Timer]
OnBootSec=1min
 
[Install]
WantedBy=timers.target

vim /lib/systemd/system/jetty11.service

[Unit]
Description=Jetty 11 Web Application Server
Documentation=https://www.eclipse.org/jetty/documentation/current/
After = syslog.target network.target
 
[Service]

systemctl daemon-reload
systemctl enable jetty11.timer #we do not enable jetty11.service too, because that service is just fully controlled by our timer
systemctl start jetty11.service
systemctl status jetty11.service
