Hi, i have using node inject as init flow. But i have a trouble.
When i unplugged my wire ethernet and after plugged, my node flow restarted...
How I can avoid this? and make it start only when my node red boots
What do the Node-RED logs show?
Did Node-RED restart for some reasons when you pulled the network cable? That's the only reason the Inject node would be triggered again.
Where i can see log?
It depends on how you installed Node-RED, and how you run it. If you can describe how you set it up, we can point you at the logs.
Im using ubuntu one device OrangePi R1+
You're going to have to work this out yourself as I can't dig through your logs.
As I said, the only reason an Inject node would fire on start is if Node-RED has restarted. So you need to look at the logs whilst pulling the network cable. (use node-red-log to stream the logs - assuming you used the pi install script you linked to) to see what Node-RED does.

That just shows lots of attempts to run Node-RED when it was already running. Again, I don't know how any of that log relates to when you pulled out the network cable.
In another post I read that the problem is:
I'm not very good at this to solve it
[error] Error: send ENETUNREACH 255.255.255.255:44818
Having a single line like that without any context makes it hard to suggest what is wrong.
What other post did you read to find that?
My guess is a node you have does not like having the network pulled out and is crashing Node-RED. Node-RED then restarts and retriggers your Inject node.
So the question is what node is causing the crash.... that isn't something we can tell you without a more complete log output from the error.
I opened an empty project and it keeps throwing that error, now I'm going to reinstall my system in case something is misconfigured
I found the problem and how do I fix it!
It turns out that I am using an orange Pi device but I installed node-red using the following link because it has debian opartive system.
Running on Raspberry Pi : Node-RED (nodered.org)
Any method of installing using those link, they broke node-red on my operating system.
The solution is the next:
Step 1:Install node-red using:
npm install -g --unsafe-perm node-red
Step2 then pm2 should be installed
sudo npm install -g pm2
pm2 start /usr/bin/node-red --node-args="--max-old-space-size=128" -- -v
pm2 save
pm2 startup
pm2 startup systemd
And last step reboot system
