what about the arc735 node in defi

@MIBDRT I'm not following. Could you explain your problem?

I am on FreeBSD 13.1. I implemented your RC script. I enabled nodered with "sudo sysrc nodered_enable="YES". I even did a "sudo chmod +x /usr/local/etc/rc.d/nodered".

The system says that nodered is running, but I do not get a node-red gui until I do a "sudo service nodered restart".

Any ideas what I may have overlooked ?

@jprovan If you open a process viewer do you see a nodejs service with a parent of a daemon service? Or do you just see a daemon service or do you see neither?

Anything in the output logs?

Well, I am sorry to have bothered you. I retraced my steps and it is working properly. Thank you for responding so quickly.

@jprovan No worries! Glad it's working

is it just me or am I missing something, because as far as I can tell node-red is running as root.
That surely can't be right, can it?

never mind, found the rc.conf setting I was missing.

Good catch. It was. I implemented a startup script that runs it as user “nodered”.

Glad you found the rc.conf setting. Is there anything I could to make that setting more visible?

Could make it default so that you only have to change the user if you don't want it to run as user nodered.

This is in reply to @kitten77.

I don't think its a good idea to change the default user in a script like this, since the Freebsd install instructions don't require the creation of a non-root user. While this is good practice and highly recommended, there is no guarantee that each of us will create that non-root user the same way, thus breaking the script and causing more work for @apearson.

I agree with @RanceH on this. We can't depend on the nodered_runAs user being created before and the people creating the user will be the ones to read the comment and know how to change the nodered_runAs user

Hello, can someone help me instaling it on TrueNAS core 13.1?

What have you tried @EliasZoockt?

I tried to run the script and than to understand the comments but i dont know what i have to do.

1. Did you Place this file in /usr/local/etc/rc.d/
2. Then Add nodered_enable="YES" to /etc/rc.config
3. Then service start nodered

how do i put the file in the path with the shell?
