Infrastructure

1. Download most current Raspbian Image

2. Use BalenaEtcher to write the downloaded image to the SD card

3. Create empty file named ssh in the root directory of the SD card

4. Create the file wpa_supplicant.conf in the root directory of the SD card

    country=AT
    ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
    update_config=1
   
    network={
        ssid="YOUR_SSID"
        psk="YOUR_PASSWORD"
    }

5. Put your SD card into your Raspberry PI and boot the device

6. Connecto to your device:

   ssh pi@raspberrypi.local

7. Use default password:

   raspberry

8. Change your password after login:

   passwd

9. Change the hostname of the device and expand the filesystem

   sudo raspi-config

10. Install/update all the dependencies

    1. ... run the script

       wget -O - https://raw.githubusercontent.com/jfuerlinger/leabox/dev/scripts/configure.sh | bash
       

    2. ... perform the steps manually

       1. Update your packages:

       sudo apt-get update -y && sudo apt-get upgrade -y

       1. Install Node JS:

       wget https://nodejs.org/dist/latest-v11.x/node-v11.15.0-linux-armv6l.tar.xz
       tar -xf node-v11.15.0-linux-armv6l.tar.xz
       sudo cp -R node-v11.15.0-linux-armv6l/* /usr/local/
       rm node-v11.15.0-linux-armv6l.tar.xz
       rm -R node-v11.15.0-linux-armv6l
       node -v

       1. Install Git:

       sudo apt-get install git -y

       1. Install libasound2-dev (needed for the npm-speaker module)

       sudo apt-get install libasound2-dev -y

       1. Install ffmpeg with needed codecs:

       git clone --depth 1 http://git.videolan.org/git/x264
       cd x264
       ./configure --host=arm-unknown-linux-gnueabi --enable-static --disable-opencl
       make -j4
       sudo make install
       cd ..
       rm -rf x264
       sudo apt-get install libmp3lame-dev -y
       git clone git://source.ffmpeg.org/ffmpeg --depth=1
       cd ffmpeg
       ./configure --arch=armel --target-os=linux --enable-gpl --enable-libx264 --enable-libmp3lame --enable-nonfree
       make -j4
       sudo make install
       cd ..
       rm -rf ffmpeg

       1. Clone the source

       git clone https://github.com/jfuerlinger/leabox

       1. Download all the npm-modules

       npm install

Instrumentation

To get some insights and telemetry data Microsoft Application Insights are used.

Therefor its needed to export the instrumentation key as a global variable:

echo 'export APPINSIGHTS_INSTRUMENTATIONKEY="<YOUR-INSTRUMENTATION-KEY>"' >> ~/.bashrc
