Depuis Raspbian Jessie, System 5 (mode de démarrage du système) à été remplacé par SystemD. Vous trouverez ci-dessous des informations traduites depuis le lien [http://nodered.org/docs/hardware/raspberrypi "Adding Autostart capability using SystemD"] (''nodered.org, anglais'')
The preferred way to autostart Node-RED on Pi is to use the built in systemd capability. The pre-installed version does this by using a {{fname|nodered.service}} file and start and stop scripts. You may install these by running the following commands
<syntaxhighlight lang="bash">
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/nodered.service -O /lib/systemd/system/nodered.service
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-start -O /usr/bin/node-red-start
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-stop -O /usr/bin/node-red-stop
sudo chmod +x /usr/bin/node-red-st*
sudo systemctl daemon-reload
</syntaxhighlight>
Info: These commands are run as root (sudo) - They download the three required files to their correct locations, make the two scripts executable and then reload the systemd daemon.
Node-RED can then be started and stopped by using the commands {{fname|node-red-start}} and {{fname|node-red-stop}} (voyez le point précédent pour plus d'informations)
To then enable Node-RED to run automatically at every boot and upon crashes
<syntaxhighlight lang="bash">
sudo systemctl enable nodered.service
</syntaxhighlight>
It can be disabled by
<syntaxhighlight lang="bash">
sudo systemctl disable nodered.service
</syntaxhighlight>
Systemd uses the {{fname|/var/log/system.log}} for logging. To filter the log use
<syntaxhighlight lang="bash">
sudo journalctl -f -u nodered -o cat
</syntaxhighlight>
Il est également possible de modifier l'environnement de systemd et utiliser un proxy. Voyez ce [http://nodered.org/docs/hardware/raspberrypi lien dans la documentation de nodered.org].
