I found some problems getting Node-RED running the way I like Linux applications to work, so I determined the following steps to make it happen.

Installing Node-RED on Raspbian for Raspberry PI

Get Node JS installed, on raspian, install nodejs

sudo apt install nodejs
sudo apt install npm
sudo npm install -g npm

Install Node-RED using NPM

sudo npm install -g --unsafe-perm node-red

Auto Start Node-Red on boot

sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/nodered.service -O /lib/systemd/system/nodered.service
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-start -O /usr/bin/node-red-start
sudo wget https://raw.githubusercontent.com/node-red/raspbian-deb-package/master/resources/node-red-stop -O /usr/bin/node-red-stop
sudo chmod +x /usr/bin/node-red-st*
sudo systemctl daemon-reload
sudo systemctl enable nodered.service
