problem auto starting node-red with pm2

[Ruben Desmet]

Hi,

on my Ubuntu 16.04 i followed the procedure "Starting Node-RED on boot" from https://nodered.org/docs/getting-started/running

The problem is i don't get node-red in the list.

the output of the procedure is:

which node-red : /usr/bin/node-red

pm2 start /usr/bin/node-red -- -v : 2.10.2 (what is that number?)

pm2 info node-red : [PM2][WARN] node-red doesn't exist

pm2 logs node-red : [TAILING] Tailing last 15 lines for [node-red] process (change the value with --lines option)

[PM2][ERROR] No file to stream for app [node-red], exiting.

pm2 list : 

┌──────┬──────┬────────┬───┬─────┬────────┐

│ Name │ mode │ status │ ↺ │ cpu │ memory │

└──────┴──────┴────────┴───┴─────┴────────┘

 Use `pm2 show <id|name>` to get more details about an app

nothing in the list.

What could be the problem?

thanks,

Ruben

Hi

Do you actually want to use pm2 or just to autorun NodeRED at start ? If the latter then the systemd approach will probably work better. See

Hi,

Thank you for your reaction.

I will try your suggestion tomorrow.

But i'm still curious, i would like to know why it doesn't work since it is clearly described as the "way to go" on the official node-red website.

Hi,

It works.

Off course i had to change some settings in the nodered.service file.

thank you

Hi

great - glad that's ok.

The docs do suggest Ubuntu users may want to use systemd... but maybe we should make that a bit more forceful...

And indeed it should work under pm2 also - would need investigation.
