if that works fine then if need be edit the node-red.service file environment varaiable for alternative user directory otherwise it will use the default `/opt/node-red`
run `./install-service` script
all should be find and the node-red should be running at :1880
`./start` and `./stop` script are systemctl aliases which can used after install
run `./update` to update the latest version of node-red and esm
