Setting up NodeLink as service on Raspberry Pi

README.md

NodeLink AutoStart on Raspberry Pi (Raspbian Stretch)

The scripts included in this Gist are designed to start io_guy's NodeLink.exe as a startup service on a Raspberry Pi running Rasbian Stretch.

Installation

1. Follow the installation instructions for setting up NodeLink here.
2. STOP when you get to "Setting up rc.local"
3. Copy the contents of the file below to a file called installService.sh in the same folder as NodeLink.exe on your RPi:
4. Install the systemd service by running:

    cd /path/to/NodeLink.exe  # Replace with actual folder you put NodeLink.exe and installService.sh in
    chmod +x installService.sh
    ./installService.sh

5. You should now be able to start/stop NodeLink.exe with:

    sudo systemctl start nodelink.service
    sudo systemctl stop nodelink.service

About

Thank you to io_guy for his awesome piece of software. I am in no way affiliated with automationshack.com, but created this script for my own benefit and wanted to make it available to anyone who could make use of it.

installService.sh

#! /bin/bash

CWD=$(pwd)
echo "Setting up NodeLink service in $CWD..."
MONO_PATH=$(command -v mono)

if command -v mono > /dev/null 2>&1; then
  echo "Mono found at: $MONO_PATH."
else
  echo "ERROR: Mono not found. Aborting"
  exit 1
