I find Node-RED really amazing but the lack of being able to manage it as a daemon quite annoyed me.
I created an init script and a systemd unit configuration to be able to manage Node-RED as any service on my Raspberry Pi.
#!/bin/bash ### BEGIN INIT INFO # Provides: node-red # Required-Start: $local_fs $remote_fs $network # Required-Stop: $local_fs $remote_fs $network # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Short-Description: Start or stop the node-red server ### END INIT INFO # Can be downloaded and installed in one go by using this command # sudo wget -O /tmp/download https://gist.github.com/Belphemur/cf91100f81f2b37b3e94/download && sudo tar -zxf /tmp/download --strip-components 1 -C /etc/init.d && sudo chmod +x /etc/init.d/node-red && sudo update-rc.d node-red defaults # User that launches node-RED (it's advised to create a new user for Node-RED) # You can do : sudo useradd node-red # then change the USER=root by USER=node-red # if you change the user, don't forget to also change the ownership of the log file (and create it if it doesn't exist): # sudo chown NEWUSER /var/log/node-red.log # else the log won't be writtable USER=root # The location of Node-RED configuration, not mandatory, leave empty/commented to let # Node-RED decides. #USER_DIR='/home/pi/node-red/' # DONT'T CHANGE unless you know what you're doing NAME=node-red DAEMON=/usr/local/bin/node-red-pi OPTIONS="--max-old-space-size=128" if [ -n "$USER_DIR" ]; then OPTIONS="$OPTIONS --userDir=$USER_DIR" fi LOG='/var/log/node-red.log' PIDFILE=/var/run/node-red.pid . /lib/lsb/init-functions start_daemon () { start-stop-daemon --start --background \ --chuid $USER --name $NAME \ $START_STOP_OPTIONS --make-pidfile --pidfile $PIDFILE \ --startas /bin/bash -- -c "exec $DAEMON $OPTIONS >> $LOG 2>&1" log_end_msg 0 } case "$1" in start) log_daemon_msg "Starting daemon" "$NAME" start_daemon ;; stop) log_daemon_msg "Stopping daemon" "$NAME" start-stop-daemon --stop --quiet \ --chuid $USER \ --exec $DAEMON --pidfile $PIDFILE --retry 30 \ --oknodo || log_end_msg $? log_end_msg 0 ;; restart) $0 stop sleep 5 $0 start ;; status) status_of_proc "$DAEMON" "$NAME" exit $? ;; *) echo "Usage: $0 {start|stop|restart}" exit 1 esac exit 0

I had better luck with the auto install when running it this way:
sudo apt-get install zip unzip sudo wget -O /tmp/download https://gist.github.com/Belphemur/cf91100f81f2b37b3e94/download && sudo unzip -j /tmp/download -d /etc/init.d && sudo chmod +x /etc/init.d/node-red && sudo update-rc.d node-red defaults

Hello Richard,
I admit I assumed most configuration came with unzip installed. But you’re right, the first step is needed if you don’t have unzip installed.
