How to setup on a Raspberry Pi

This is only tested on a Rasperry Pi 2
I assume that Raspbian 'wheezy' was installed and configured to the personal needs.
This how-to works with a vanilla Raspbian installation.

Update rasbian and firmware

Make sure the system is up to date:

sudo apt-get update
sudo apt-get dist-upgrade -y
sudo rpi-update
sudo reboot

Install requirements

Alternatively you can execute the rpi2_raspbianWheezy.sh which will install all the dependencies listed below

First we need to install the dependencies:

• node.js v0.10
• mongoDB
• gulp & bower
• mopidy

Installing node

First we install a decent repository for node (taken from here):
curl -sL https://deb.nodesource.com/setup_0.10 | sudo bash -

And then install node:
sudo apt-get install -y nodejs

Make sure the latest version of npm is installed:
sudo npm install --global npm

Installing mongoDB

This is a bit tricky since there is no official build of mongoDB for the Pi.
We'll use a 3rd party package.
Remember that you should never use packageds from an unknown source when deploying a productive system.
But since this is for personal use we'll use this package anyway.

Download, install & setup:

wget https://github.com/tjanson/mongodb-armhf-deb/releases/download/v2.1.1-1/mongodb_2.1.1_armhf.deb
sudo dpkg -i mongodb_2.1.1_armhf.deb
sudo /etc/init.d/mongodb start

(Optional) add mongoDB to autostart:
sudo update-rc.d mongodb defaults

Installing gulp & bower

This is simple:

sudo npm install --global gulp bower

Installing mopidy

The official guide for installing mopidy on the Pi stats that you should execute the following commands for a proper mopidy setup:

sudo modprobe ipv6
echo ipv6 | sudo tee -a /etc/modules

If you want sound output via the analog output, execute:

sudo amixer cset numid=3 1

And test with

aplay /usr/share/sounds/alsa/Front_Center.wav

Now, to install mopidy:

# Add the archive’s GPG key
wget -q -O - https://apt.mopidy.com/mopidy.gpg | sudo apt-key add -

# Add the repo
echo '# Mopidy APT archive' | sudo tee -a /etc/apt/sources.list.d/mopidy.list
echo 'deb http://apt.mopidy.com/ wheezy main contrib non-free' | sudo tee -a /etc/apt/sources.list.d/mopidy.list
echo 'deb-src http://apt.mopidy.com/ wheezy main contrib non-free' | sudo tee -a /etc/apt/sources.list.d/mopidy.list

# Install mopidy
sudo apt-get update
sudo apt-get install -y mopidy mopidy-spotify

Setting up mopidy

To initialize the mopidy config file, simply run mopidy, wait a few seconds (there might be some errors, ignore them for now) and stop with Ctrl+C.
Now open at the file ~/.config/mopidy/mopidy.conf with your favorite editor.

This file is seperated into section, each starting with [SECTION]. Lines starting with a # are comments and do not have any effect.

For a pure spotify setup, we'll need to make changes to the spotify section.
Uncomment (e.g. remove the #) from enabled, username and password.
Set enabled to true and fill in username and password.
If you want you can also set the bitrate to 320 (don't forget to uncomment).

As of yet, local files are not supported, therefore they have to be disabled in mopidy. Uncomment the enabled line in the local section and set it to false.

Start mopidy again.
There should be no errors and mopidy should successfully connect to spotify and load your playlists.

Install, setup and start Livid

Pull the repo:

git clone https://github.com/eljenso/livid.git

Setup Livid:

cd livid
npm install
bower install

Change the playlist in config.js by changing defaultPlaylist to your needs.

Finally, start Livid:
node server.js
