Hello everyone! My question would be with what rights install node red, google recognizer, python3 so that there are no dependencies. Because it is in node red, e.g. the bigexec node, from which I run a python script that uses google recognizer and portaudio. However, citing the node red portaudio…

Yes, permissions, especially hardware permissions in Linux can get complex. And you can see from the very many rubbish tutorials on the interweb that many people don't bother to even attempt to get this right. But Linux permissions are fine-grained and not so hard to understand with a little effort…

Well, it's like: if sudo systemctl enable nodered.service, then node red starts automatically with the raspberry, but the script does not run. if systemctl enable nodered.service, then node red must be started from putty (node-red), the script runs, but if I exit putty, node red also stops

If there is a difference when you run with systemd rather than running node-red then it is a difference in the environment between those two. Show us the systemd service script and tell us which user you are logged in as when you run node-red.

I wrote the system service script above. (but by default : sudo systemctl enable nodered.service ) There is one user. Node red needs to start automatically with raspberry. Now I'm looking for (perhaps a solution) to start node red automatically, but as a user.

I'm not running my script back and forth, I just described how I've tried it so far. My own script starts from putty with the same user that I specified in the raspberry imager during the raspberry installation. I tried in putty as a user and with sudo, but it doesn't run with sudo. I tried bigexec,…

[image] jbudd: I believe that you need to use sudo to run systemd commands, except for systemctl status nodered. If you run sudo systemctl enable nodered (the .service suffix is not necessary), then Node-red should start up automatically the next time you reboot. That is correct. However, no…

[image] azxo1: This method is not good only because node red does not start automatically with raspberry because it is not sudo systemctl. My understanding is that systemctl enable nodered will do nothing. It certainly will not start node-red. As @Colin says, the user which node-red runs as…

Then this would be the correct start? : sudo systemctl enable nodered sudo systemctl start nodered GalZoli:GalZoli to automatically start as user when booting? But that's the way it is: /lib/systemd/system/nodered.service : [Service] Type=simple # Run as normal pi user - change to the user nam…

I can't see it. Please post it again.

You do that in the systemd service script.
