I'm trying to autorun Node-red on a laptop running Ubuntu 18.04.3 LTS Bionic.
I followed below web page...
"node-red" command works.
But I can get Node-red to run on boot!
Can anyone help me troubleshoot this, please?
Thank
IDeeW
I also tried below solution but the issue is still there...
If you install node red using the pi install script, which also works on Ubuntu, that will setup the systemd script for you. Doing this will not destroy your existing flows, though I am sure you have backups anyway.
That tutorial says that it installs nodejs version 4.x, which went out of support years ago You need at least 10.x to run the current node red version.
Ok. Let me try the Pi scripts.
Trying out Node-Red for the first time. So no existing flows to back up..
will update the results...
Thanks
this is what happens after I run "node-red" command
But "sudo systemctl start node-red" will not run Node-red.
It does run node-red, but in the background. node-red-start is like an alias that combines the background starting with viewing the log file. See sudo systemctl status nodered to verify that it runs. Or node-red-log to view the logs at any time.
To have it start on boot, sudo systemctl enable nodered.
and what does node-red-log say? or sudo systemctl status nodered for that matter?
Here's what it looks like on my ubuntu server 19.10, installed through the script and set to run on boot through sudo systemctl enable nodered.
if it didn't start because of an error, it will show in the status command
What does node-red-start show. That should start it with systemd and then show the startup messages
Odd, post here /lib/systemd/system/nodered.service I suspect there is an issue there. Can you copy/paste logs and file contents rather than screenshot, it is much easier to deal with? Thanks.
[Edit] Also what do
ls -l /usr/bin/env
and
which env
show?
I have the script on the below path
/etc/systemd/system/node-red.servic
I added the .txt to the end
node-red.service.txt (380 Bytes)
indika@WEERAServer:~$ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.0.96:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

That is not the right service file. Look at the systemd status output and you will see it is where I suggested. Also the one you have posted is node-red.service, whereas the correct one is nodered.service.
Sorry, I didn't mean you to repost all the stuff you had already posted, I just meant for the future, the systemd script for example. I you click the </> button above the edit box when posting and paste the text there it will stop the forum from reformatting it.
Also what do
ls -l /usr/bin/env
and
which env
show?
indika@WEERAServer:~$ ls -l /usr/bin/env
-rwxr-xr-x 1 root root 35000 Jan 18 2018 /usr/bin/env
indika@WEERAServer:~$ which env
/usr/bin/env
indika@WEERAServer:~$
Also make sure you systemctl disable node-red or it will be trying to run that one on boot as well as nodered.service.
Well env looks alright, so I think it is back to the systemd script, if you can find the right one. It must be there as systemd status found it.
found it under "/lib/systemd/system/"

Thanks
[edit]
YES....that's it...
everything is working as soon as I change the user & group to "indika".....
Thanks u so much Colin and everyone.

Well that is very odd, the install script has not put your user name in the script. I presume you were logged in as your normal user when you ran the script, and didn't use sudo. Whatever, to fix it edit that file and change the user and group from pi to your user name (indika). Then so that systemd will reload it
sudo systemctl daemon-reload
then
node-red-start
Assuming that fixes it I would like to understand what went wrong. Can you post the install log please, /var/log/nodered-install.log
[Edit] Oh, change the Working Directory too.
