Raspberry Pi Setup

[WARNING] The following instructions were done in a RaspberryPi 3

• Open the terminal inside your Raspberry Pi

• Update your Raspberry Pi

  • sudo apt update

• Install NodeJS 10 or greater:

  • Follow the steps here

• Install the Go lang compiler:

  • Follow the steps here

• Install GoCV:

  • Follow the steps here

• Create a workspace folder:

  • mkdir ~/Desktop/workspace

• Navigate to the workspace folder:

  • cd ~/Desktop/workspace

• Clone this repository:

  • git clone https://github.com/RaspberryPiPlantMonitor/backend

• Navigate inside the backend folder:

  • cd ~/Desktop/workspace/backend

• Install project dependencies:

  • go mod tidy

• Navigate back to the workspace folder:

  • cd ~/Desktop/workspace

• Clone the frontend repository:

  • git clone https://github.com/RaspberryPiPlantMonitor/frontend

• Navigate inside the frontend folder:

  • cd ~/Desktop/workspace/frontend

• Build the frontend code and move the build directory to the backend folder

  • npm install
  • npm run build
  • mv ~/Desktop/workspace/frontend/build ~/Desktop/workspace/backend/build

• Navigate back to backend:

  • cd ~/Desktop/workspace/backend

• Change the ~/Desktop/workspace/backend/.env file with the setting you desire

Running the Raspberry Pi server

• Install ngrok

  • sudo apt install unzip
  • cd ~/Desktop
  • wget https://bin.equinox.io/c/4VmDzA7iaHb/ngrok-stable-linux-arm.zip
  • unzip ngrok-stable-linux-arm.zip

• Run ngrok:

  • nohup ./ngrok http 8080 > ngrok.log &

• Navigate to backend folder:

  • cd ~/Desktop/workspace/backend

• Run the server:

  • nohup go run main.go fifo.go > ngrok.log &

• Check your ngrok endpoint by doing:

  • curl http://localhost:4040/api/tunnels
  • Copy the public_url url. It starts with https

Extra commands

• Check server logs:

  • tail -f ~/Desktop/workspace/backend/ngrok.log

• Check your nohups jobs by running:

  • jobs -l
