How to Turn a Raspberry Pi Into a Private Streaming Music Service

If you're sick of dealing with carrying around a massive library of music on your smartphone and you don't want to pay for a service like Google Music, the Raspberry Pi can work as a music server. With a little work, you can make all your MP3s available to you regardless of where you are. Here's how to set it up.

We're assuming you have a basic understanding of the Raspberry Pi, but if not, you can start here to get everything in order.

What You'll Need

• Raspberry Pi: If you're not sure where to buy one, check out our introduction to the Pi for more info.


• A 4GB SD card: You'll need something to install the operating system onto. This page tells you which SD cards are compatible with the Pi.


• Ethernet cable or Wi-Fi adapter: You'll need the internet to set up and run your music streaming service.


• USB keyboard: You'll just need it for the initial setup.


• iOS or Android device, or computer to stream to: The purpose of this service is to send your music from your Raspberry Pi to your remote devices, so you'll want to have some remote devices.


• A $1/month subscription to Subsonic Premium : After testing a bunch of free options options for setting up a music server on the Raspberry Pi, Subsonic won out by being the easiest to use with the best support. While there is a monthly fee for streaming your music over the internet, Subsonic is free to check out for 30 days.


• A place to store your music: Your Raspberry Pi will feed your music to the outside, but you'll still need to actually store those MP3s somewhere. This could be a NAS or external hard drive.

What You'll Get

When you're done, you'll have access to your entire music library from anywhere you have an internet connection, all through a tiny box in your house hooked up to your router. To do this we'll install Subsonic on the Raspberry Pi. You can then access your library of music from apps on your smartphone or a computer. You can also share that library with friends, create playlists together, and more. Essentially, it'll be your own private little Spotify-like service (or, perhaps more accurately, Google Music).

Subsonic works on any computer, but it's especially handy on the Raspberry Pi because you don't need to worry about the cost of running your computer all the time, or about exposing your main computer to the internet. With the Raspberry Pi, you can set it up, tuck it away in a corner somewhere, and leave it on 24/7 without worrying too much about it.

Step One: Set Up Raspbian

In order to use your Raspberry Pi as a private streaming music service, you'll need to get the Raspbian operating system installed onto your SD card. Our guide here shows you exactly how to do that. Once that's taken care of and you can boot to the command line, we'll run an update. Type this into the console:

sudo apt-get update  sudo apt-get upgrade

Sit back and wait for the update to run. It can take a little while to grab everything.

Step Two: Update Java

The software we're going to use to stream music from the Raspberry Pi works significantly better with the newest version of Java installed. So, we're going to install OpenJFX manually. To do this, head to the Java download page from your home computer, click the "Accept License Agreement" button, right-click the link underneath "Download," and select "Copy Link Address." Head back to the Raspberry Pi, and type this into console:

wget [link you just copied]

it should look something like

wget http://ift.tt/1mKFdeM

Once it's downloaded, make a directory for the installation:

mkdir -p /opt

Then unpack it:

sudo tar zxvf [file you downloaded] -C /opt

For example, it should read:

sudo tar zxvf jdk-8-linux-arm-vfp-hflt.tar.gz -C /opt

Now we need to make the new Java installation the default one:

sudo update-alternatives —install "/usr/bin/java" "java" "/opt/jdk1.8.0/bin/java" 1

then

sudo update-alternatives —set java /opt/jdk1.8.0/bin/java

Test to make sure the correct version of Java is installed with:

java -version

Finally, some programs, including Subsonic, need to know where to look for this new version of Java. So, we'll need to edit some text files. Type this into a terminal:

sudo nano /etc/environment

and add in the line to the text file:

JAVA_HOME="/opt/java/jdk1.8.0

Save the file and head back to the command line. We'll do the same with the bash console:

sudo nano ~/.bashrc

Add the lines:

export JAVA_HOME="/opt/jdk1.8.0"

export PATH=$PATH:$JAVA_HOME/bin

Save the file and then everything's all set. Reboot the Pi and we'll get the music server ready.

Step Three: Install Subsonic

Now it's time to get Subsonic, the software that's actually going to power the music streaming, installed. We'll need to get the download link the same way we got the Java one. Head to theSubsonic download page from your home computer, click the Debian installer link, right-click the "Direct Link" and select "Copy Link Address." Now, on the Raspberry Pi, type in:

wget [the URL you copied above] -O subsonic.deb

For example:

wget http://ift.tt/1mKFb6C

Once it downloads, type this in to install it:

sudo dpkg -i subsonic.deb

Now Subsonic is installed, but since we're opening up the Pi to the internet, we need to take a few security precautions. This means creating a new user that doesn't have root access. So, type in:

sudo adduser [new user name]

For example:

sudo adduser subsonic

Now we'll edit Subsonic's configuration with this new info. Type in:

sudo nano /etc/default/subsonic

Next, add the following line to end of the text file:

SUBSONIC_USER=[new username]

Then, restart Subsonic:

sudo service subsonic restart

Subsonic is now running on the Raspberry Pi as the user you just created so it doesn't have root access. It's also automatically set to run when you boot up the Pi in the future.

Step Four: Set a Static IP Address

Now, we need to give the Raspberry Pi a static IP address so you can always access it by typing the same URL into your browser. First off, we need to get a picture of what your home network looks like. Type in:

ifconfig

This shows you where and how you're connected to your router currently. Pay attention to the "inet addr" number, which should look something like 192.168.1.115. Write that number down. Now we need to get the default gateway number. Type in:

route -n

The default gateway is listed on the line the the "UG" flag. It's usually your router's address, for example: 192.168.1.1. Make a note of that. Next, edit the configuration file:

sudo nano /etc/network/interfaces

Here, you'll see a line that reads something like: iface eth0 inet dhcp. Replace it with:

iface eth0 inet static

address [the IP address you wrote down above]

netmask 255.255.255.0

gateway [the gateway you wrote down above]

That's it. Now your Raspberry Pi has the same IP address every time so it's easy to connect to. If you need more information, you can find a full guide to setting up a static IP address here or set up much better and easier to use DHCP reservations.

Step Five: Configure Subsonic

Once you have Subsonic running on your Raspberry Pi, it's time to access it from your home computer. From a browser, type in the IP address like so:

[ip address you just got]:4040

For example:

192.168.1.115:4040

That pulls up the Subsonic login page. Log in with the username admin and the password admin.

First things first, follow the instructions to change your username and password. Next, we'll point Subsonic to a music library.

Click Settings > Media Folders, and change the media folder to where you have your music stored on the Raspberry Pi. If you're using an external hard drive or USB drive, follow one of these guides to set those up first. Now, you can access your music library from anywhere within your local Wi-Fi network. But that's not enough. Let's grant access to that library from anywhere:

1. Head into Settings > Network


2. Check the box for "Automatically configure your router to allow incoming connections to Subsonic


3. Check the box for "Access your server over the Internet"


4. Enter the URL address you'd like to access it from


5. Click the Save button

Wait for Subsonic to reload. If everything works, your status should be listed as: "Successfully registered web address." You can now access your music library from anywhere at the URL you created.

If the status shows anything else, it means your router doesn't support automatic port forwarding so you need to set it up manually. This guide walks you through the basic steps, but setup and troubleshooting depends on your specific router.

Step Six: Configure Subsonic's Mobile Apps

Subsonic is accessible from a ton of different apps on both desktop and mobile. After testing a few out, I liked Submariner on Mac and Audiophone on iOS the most. Setup depends on which app you use, but it's usually pretty straightforward. You'll just need the server address and port from step four, as well as your user login information. Once it's set, you'll be able to pull up your library from anywhere as long as the Raspberry Pi is on and the Subsonic server is running.
