How to automatically start Nodered on boot?

Question

I want to automatically start nodered on boot. I'm using a raspberry 3 model B v2.

According to those instructions "https://nodered.org/docs/getting-started/raspberrypi" , I have install and create a flow.

I'm using Node-RED version: v0.20.7 Node.js version: v8.16.0

When I start nodered using node-red-pi --max-old-space-size=256 it's working perfectly.

But now I want to use it as a service and launch it automatically. Following the same instructions, I ran the command sudo systemctl enable nodered.service. The reboot, and nothing happened. Nodered didn't start.

I tried to run it directly as a service using node-red-start, and I got this error message

Starting as a systemd service.
Unit nodered.service entered failed state.

Has someone an idea about this error and how to fix it? There is another way to start nodered automatically?

The error /usr/bin/env: node-red-pi suggests node-red hasn't installed properly. Try rerunning the update-nodejs-and-nodered script from the documentation. If it still fails, come talk to us on the forum where we can debug it better. SO isn't the best place to debug an issue of this nature. — knolleary
'node-red-pi --max-old-space-size=256' uses nodered v8 and it works. But 'node-red-start' uses nodered v10 and it does not work. Do you have an idea how to configure 'node-red-start'? — Anthony
I found the file node-red-start using "which node-red-start". How to force it to use nodeJS v8? I think it will solve my problem. — Anthony
Hi @knolleary I'm having this issue - seems like the exact same one - I've posted on the Node-Red forums as dclear - if you could help I'd be very grateful thanks — daneee

I was facing the same problem a while ago. you can use nohup to start it automatically or not to end the session even you close the device.

Just install nohup, and type nohup node-red. If you want to check status, write nohup status in the terminal. for stoping, nohup stop node-red. Enjoy :)
