+-  cd /etc/systemd/system
+-  Create a file named your-service.service and include the following:
+```shell script
+[Unit]
+Description=Support Portal API
+
+[Service]
+User=supportuser
+WorkingDirectory=/var/lib/supporthome
+ExecStart=/var/lib/supporthome/support-portal.jar
+Restart=always
+Environment="SPRING_PROFILES_ACTIVE=aws-local"
+
+[Install]
+WantedBy=multi-user.target
+```
+-  Reload the service files to include the new service.
+    -  `sudo systemctl daemon-reload`
+-  Start your service
+    -  `sudo systemctl start supportapi.service`
+-  To check the status of your service
+    -  `sudo systemctl status supportapi.service`
+-  To enable your service on every reboot
+    -  `sudo systemctl enable supportapi.service`
