Setting up a headless linux music server
  1. Stop the old service if it is running with sudo servuce squeezelite stop
  2. Remove the old version if installed with sudo apt-get remove squeezelite
  3. Install its dependancies sudo apt-get install lsb-base libasound2 libavcodec57 libavcodec-extra57 libavformat57 libavutil55 libc6 libfaad2 libflac8 liblirc-client0 libmad0 libmpg123-0 libsoxr0 libvorbisfile3
  4. Create a directory to download the source files in your home drive mkdir sources; cd sources
  5. Clone the source code git clone https://github.com/ralph-irving/squeezelite.git
  6. cd squeezelite
  7. sudo apt-get install libavcodec-dev libavformat-dev
  8. sudo apt-get install libsoxr-lsr0 libsox-dev sox libsoxr-dev
  9. Build it with make all OPTS="-DDSD -DRESAMPLE -DFFMPEG"
  10. sudo cp squeezelite /usr/bin/. to copy the file to you path
  11. To enable autostart copy and edit as needed the defaults settings file to /etc/defaults. And the startup script to /etc/init.d. These files need editting as described in linux_music_server.md
  12. and run sudo systemctl daemon-reload and then sudo servuce squeezelite start

To compile this on Linux Mint 19.2 I also had to install: libflac-dev, libmad0-dev, libvorbis-dev, libmpg123-dev, libfaad-dev via apt-get.

  1. This is a work in progress. Use at your own peril.

  2. To auto-rip the cds inserted into my headless music server I'm going to use abcde and cdparanoia. Install them with sudo apt-get install abcde lame eyed3 glyrc imagemagick cdparanoia1

  3. MusicBrainz is missing some dependencies so run sudo apt-get install libmusicbrainz-discid-perl libwebservice-musicbrainz-perl

  4. After running abcde-musicbrainz-tool from the command line I got an error about missing Mojo::DOM. Fix this with sudo cpan install Mojo::DOM

  5. We need to a config file for abcde. This is abcde.conf. There are multiple places that this could go (see the man page), but since I have a single user setup for now I am placing this in my users home directory /home/phil/.abcde.conf, but I could place it anywhere else and get the program to read it with the -c [filename] option. Placing it here means if I run abcde from the command line, this will be the default configuration.

  6. Edit the your .abcde.conf file to use the correct ripper and write to files to the correct place.

    # wish to submit your edited cddb file.
    NOSUBMIT=n

    VAOUTPUTFORMAT='${OUTPUT}/Various-${ALBUMFILE}/${TRACKNUM}.${ARTISTFILE}-${TRACKFILE}'
    # This function takes out dots preceding the album name, and removes a grab
    # bag of illegal characters. It allows spaces, if you do not wish spaces add
    # in -e 's/ /_/g' after the first sed command.
    mungefilename ()
    {
    
        CDDISKID=$(cd-discid "$CDROM")
        FIRSTPART=$(echo $CDDISKID | cut -d' ' -f1)
        echo $FIRSTPART "$@" | /home/phil/dev/munger.py
    }
    
    MAXPROCS=2                                # Run a few encoders simultaneously

    EXTRAVERBOSE=2                            # Useful for debugging
    INTERACTIVE=n
    post_read()
    {
    
    }
    #ok, now we need to set the correct ownership for the flac files.
    post_encode ()
    {
        ARTISTFILE="$(mungefilename "$TRACKARTIST")"
        ALBUMFILE="$(mungefilename "$DALBUM")"
    
        if [ "$VARIOUSARTISTS" = "y" ] ; then
            FINDPATH="$(eval echo "$VAOUTPUTFORMAT")"
        else
            FINDPATH="$(eval echo "$OUTPUTFORMAT")"
        fi
    
    FINALDIR="$(dirname "$OUTPUTDIR/$FINDPATH")"
    C_CMD=(chown -R phil:lms "$FINALDIR")
    #echo "${C_CMD[@]}" >>tmp2.log
    "${C_CMD[@]}"
    }
    

    munger.py strips any odd unicode out of the string to make the filename safe. It can be donwnloaded from here Most of the above is straight forwards abcde configuration. It uses cdparanoia to rip the cd, musicbrainz to find the track information and then it uses flac encoding. The mungefilename() function removes any unwanted characters from the file name and also appends the discID number onto the directory name for any unknown album - otherwise abcde will overwrite it. The post_encode() function changes the ownership of the files to phil:lms. You will need to edit this. TODO: Currently this is placing all the temp files in / which might be a problem.

  7. The ownship of the directory /home/phil/storage/music/flac/abcde and /home/phil/storage/music/flac/abcde/flac will need correcting with sudo chmod -R /home/phil/storage/music/flac/abcde

  8. Test the configuration by inserting a CD and ripping it from the command line. abcde -c /home/phil/.abcde.conf

  9. Ok, so how to get it to autorip when a CD is inserted. For this the udev is needed which is the Linux device manager. We need to get to trigger a command when it detects a CD is inserted. However, udev does not allow long running programmes to be run. If you try to call abcde directly you will find udev kills the process before its finished ripping. To get around this we create a new service and get udev to start the service.

  10. Create a new file /etc/systemd/system/ripper.service with the following

    [Unit]
    Description=Auto CD ripper
    
    [Service]
    Type=oneshot
    ExecStart=/home/phil/dev/rip.sh
    
    [Install]
    WantedBy=multi-user.target
    
  11. And create the /home/phil/dev/rip.sh file which gets run

    #!/bin/bash
    LOCKDIR=rip.lock
    LOGFILE=/home/phil/dev/log.txt
    
    function cleanup {
    
     if rmdir $LOCKDIR; then
        echo "Finished $(date)" >> $LOGFILE
    
    else
        echo "Failed to remove lock dir '$LOCKDIR'" >> $LOGFILE
        exit 1
    
    fi
    
    }
    
    if mkdir $LOCKDIR; then
        trap "cleanup" EXIT
        echo "Acquired Lock, running" >> $LOGFILE
        echo "Started $(date) $$" >> $LOGFILE
        abcde -c /home/phil/.abcde.conf
        #trigger LMS rescan
        wget -q --spider http://localhost:9000/settings/index.html?p0=rescan
        echo "Stopped $(date) $$" >> $LOGFILE
        # optional notifications, uncomment if needed
        # echo "Sending IFFT webhook:">>$LOGFILE
        # /home/phil/dev/ifttt_send.sh "Ripper done. Please eject CD" >> $LOGFILE
        # send the logfile by email, you need to configure mail  first for this to work
        # cat $LOGFILE | mail -s "Ripper log" your_email@example.com
    else
        echo "Could not create lock, already running? '$LOCKDIR'"
        exit 1
    
    fi
    

    This file basically only allows abcde to run as a single instance. It needs to be made executable with chmod u+x /home/phil/dev/rip.sh The wget command triggers the LMS rescan which looks for new media. The LOGFILE is really only useful to see if the script is working, you might want to set it to /dev/null eventually. The ifttt_send.sh used IFTT to send a notification that the process has finished to my phone. You need an IFTT account. I created a Maker Event called ripper_done that connect to a rich text notification. The ifttt_send.sh contains:

    #!/bin/bash
    source /home/phil/dev/ifttt_key.sh
    CMDSTRING=("curl -H \"Content-Type: application/json\" -X POST -d '{\"value1\":\" $1\"}' https://maker.ifttt.com/trigger/ripper_done/with/key/$IFTTT_KEY")
    eval $CMDSTRING
    

    ifttt_key.sh defines IFTTT_KEY which you need. It a single line export IFTTT_KEY="YOUR KEY VALUE"

  12. Start the service

    sudo systemctl daemon-reload
    sudo systemctl enable ripper.service
    

    Now if you place a CD in the drive you should be able to rip it by running sudo systemctl start ripper. The status of the ripping can be obtained with systemctl status ripper

  13. We now make a udev rule to trigger the service start when a cd is inserted. Create a file /etc/udev/rules.d/99-cd-audio-rip.rules with the following

    SUBSYSTEM=="block",KERNEL=="sr0",ACTION=="change",RUN+="/bin/systemctl start ripper"
    

    sr0 is the name of my CD-ROM drive. Now add the rule with sudo udevadm control --reload

  14. Now when you insert a CD it should autorip. You can always test the progress of the ripping with systemctl status ripper

1: My apt-get version of abcde was 2.9 which has a bug and crashes if Musicbrainz returns an unknown disc. To fix it we need to update it. Remove abcde with sudo apt-get remove abcde, download the latest version from here 2.9.2 at the time of writing. Untar it, enter the directory and run sudo make install. Since we removed the managed version of abcde the dependencies will be marked for removal. To stop this install them sudo apt-get install vorbis-tools cd-discid fdkaac. You might want to check for other dependencies if you have a problems with apt-cache depends abcde.

For years I've been using Vortexbox as my music server at home. It's basically a headless linux server configured with Logitech Music Server, an automatic CD ripper, a software player (for local sound playback) and a reasonable web interface. Vortexbox however hasn't been updated for years. The maintainer is promising an update but I didn't want to wait and instead set out to build my own. This is running on a HP micro-server (1.2GHz Atom) and I have Naim DAC plugged into it via USB for music.

It should be possible for anyone to install this but it is complicated and I'm not sure I'd recomend this to anyone with either no Linux experience or no desire to learn Linux.

  1. Install Lubunutu - This version comes with a GUI. I could have used one of the server versions, but the GUI is handy for the intial setup. My thought process on the distro didn't going beyond this! I'm not going to go into detail here on the install becuase there plenty of tutorials online.

  2. Setup a user, my is phil

  3. We will also need ssh to remote login sudo apt-get install openssh-server. The rest of the set up can be done locally or now remotely via SSH.

  4. My server has 3 hard drives. One contains the OS, one is the music, one is for backup. The music files are going to be stored in the user home space rather than the root. So I edited fstab to mount my music drive in /home/phil/storage/ . Your setup may well be different. My music is held in /home/phil/storage/music/flac

  5. Install LMS (Logitech Media Server). It has a dependancy so run sudo apt-get install libio-socket-ssl-perl to install it. Download the latest version of LMS from http://www.mysqueezebox.com/. Once downloaded sudo dpkg -i logitechmediaserver_7.9.2~1530185314_amd64.deb. You will need to change the name of the .deb file for the version you downloaded. Then run sudo apt-get -f install and start the service sudo service logitechmediaserver start. You should then configure the users and group settings.

    sudo usermod -aG audio squeezeboxserver
    sudo usermod -aG lms squeezeboxserver
    sudo usermod -aG audio phil
    
  6. Create a Playlist folder somewhere and set the file group ownership to lms with sudo chown phil:lms -R Playlistand maybe sudo chmod -R 744 Playlist. The music files also need to belong to the lms group so sudo chown -R phil:lms /home/phil/storage/music/flac

  7. Open a web browser and the address will be http://[ip address of your machine]:9000. Configure LMS so that it knows the location of the music and playlist folders. Rescan the LMS music library. LMS should now be running. It's probably not a bad idea to fix the IP address of your machine. You can normally do this with your routers web interface, or by setting the network configuration of your server (the router method is normally the easiest.)

  8. To add music to our folder over the home network we need samba to share a folder. sudo apt-get install samba, and create a samba user sudo smbpasswd -a phil. Edit the samba config sudo vi /etc/samba/smb.conf and add to the end

    [music]
    path = /home/phil/storage/music
    valid users = phil
    read only = no
    

    Restart the service with sudo service smbd restart and test the smb.conf config is valid by running testparm

  9. Install squeezelite player via the systems package manager(sudo apt-get intsall squeezelite). [Update: the repo version is rather old and seems unstable on my system. I recommend instead building from the source code. see here ].Now run squeezelite -l which should list the available audio devices. Running squeezelite from the console will start the program. If you are like me running squeezelite from the console works - it should appear as a player under the LMS webpage. ^C kills the player.

    The problem here is I would need to log in and run the command every time. It's far better to run this as a service that starts automatically on boot. The service should be installed via the package mangager but the default configuration probably does not work. I think this is becuase the default sound card option is via pulse audio and this cannot be run as root. In the output of squeezelite -l there is (hopefully) one option starting with hw:, in my case it is hw:CARD=Audiophilleocom,DEV=0. This is the direct hardware option and it is the one we want. In /etc/default/squeezelite add the line SL_SOUNDCARD="hw:CARD=Audiophilleocom,DEV=0" or whatever your equivalent is. Restart the service with sudo service squeezelite restart and hopefully it is all working. 1

  10. Since the server is headless we don't need to waste resources running the GUI. Switch to console login via sudo systemctl set-default multi-user.target

  11. Vortexbox automatically ripped CDs when inserted. See here for my version that uses abcde.

  12. TODO A web gui

  13. On site and off site backups

1: I have had a few problems with Squeezelite crashing and I am currenlty looking into this. I suspect the pulseaudio might be the problem and it might need to be disabled. Since we aren't using the desktop, this should be ok. Do not uninstall pulseaudio as some forums suggest. It can be disabled gobally by editting /etc/pulse/client.conf and changing the line ; autospawn = on to autospawn = off. Note the removal of the ;. My system now seems stable, however, its hard to say if it was pulseaudio or rebuilding the squeezelite from source that solved the problem. If you still have problems, it might be an idea to increase the ASLA buffersize
