I just ran `sudo systemctl enable nodered` for the first time and now I have both the files.  
Thus, Node-RED should restart on server reboot.  
Now I need to remove restarting command from the crontab file.  
PS. Node-RED is running on Apache2 server Ubuntu 18.04

Yes. Run the script when logged in as the user that should run node-red.  
Or you could just edit the systemd service file `/lib/systemd/system/nodered.service` and change all references to `root` to the user you want. So that is User, Group, Working directory, and environment file.  
Then reboot.

Thanks for the explanation. I will do the modifications accordingly.
