Shutdown Node

[Joshua Finnegan]

Just to clarify I'm pretty new to nodered

Is it possible to create a node that shuts nodered down using the command 'shutdown -p now'.

This is possible with the node 'exec' but that involves input. I don't want any user input into this except for maybe pressing a button to trigger it.

All help appreciated

We do this in theThingbox.io: we have a menu to restart NR and one to reboot the Thingbox. Linked to an exec node that reboot.

The pb is that if we often need to reboot because NR is down, and in this case, it just don't work to use NR to reboot!

it seems NR does not run the flow if node classes are missing. This is a pb since missing node classes usually just prevent only a part of the flow to run.

Thank you for your reply. Though is there a way to do this on windows OS as I don't have a Pi

Hi Joshua,

if you want to just stop node-red, you could use an exec node that will run taskkill with the appropriate arguments (not a Windows user here, but there are plenty of guides for using taskkill out there.)

if you want to shutdown the machine, again, an exec node that calls shutdown with the appropriate arguments should be all you need.

If I'm right you have one to reboot the Pi and another to reboot Node-Red but not one to actually shut down the Pi - I'm still working on that after my normal "shutdown now" command failed :-)

Peter

shutdown is a root command so you need to either run Node-RED as root - or give shutdown the suid .

But this does mean that any user can then run shutdown...

sudo chmod u+s /sbin/shutdown

[Dave C-J]

In fact ... on Pi that is a VERY BAD way to do it.... as they alias poweroff, shutdown, reboot and a load of other things to the same underlying app... so giving suid to one does it for all... which obviously is not what you want...

In Thingbox you are root! I will try those switches thanks

I'm sure it is just me - I cannot find any way to turn THETHINGBOX off ! You can reboot - you can restart node-red but I am not seeing any way to turn the Pi off - either in Thethingbox itself - or on the web (related to this - obviously one would normally use something like shutdown in a terminal etc). Surely if this is to encourage people who are not programmers there should be a shutdown button in the program - or am I looking straight at it and not seeing it.

Best try the Thingbox forum....

Couldn’t find one – anyway, all figured out and on the blog!
