Minimum raspbian setting for Music

Setting overview

The following are configured automatically.

• Build the latest alsa-lib, libflac, mpg123, FFmpeg and MPD with optimization options for Raspberry Pi 3
• Specify high priority to MPD tasks
• Turn off the power led after initialization
• Provide cover art via http using nginx
• Scrobble to last.fm using mpdas
• Disable swap, HDMI, Wi-Fi, Bluetooth, UART, onboard audio, usb-power and unnecessary service
• Put temp and log files to RAM disk
• Decrease GPU assigned memory
• Suppress rsyslog and nginx output
• Specify NTP server, timezone and language for Japanese
• Configure NAS

Setting script

Download files:

mkdir ~/setup
cd ~/setup
wget https://gist.githubusercontent.com/estshorter/302449b697c1468bcfdb0bf31ed3b35e/raw -O ./setup.sh
chmod u+x ./setup.sh

File urls:

• raspi-autosetup.sh: https://gist.github.com/estshorter/302449b697c1468bcfdb0bf31ed3b35e

Execute all scripts:

Note: specify NAS_USER, NAS_PASS, NAS_ADDR, LAST_FM_USER, LAST_FM_PASS before third executing.

cd ~/setup
./setup.sh
sudo reboot

cd ~/setup
./setup.sh
sudo reboot

export NAS_USER=user
export NAS_PASS='pass'
export NAS_ADDR=addr
export LAST_FM_USER=user
export LAST_FM_PASS='pass'

cd ~/setup
./setup.sh
sudo reboot

Note: I'm afraid most references in the scripts are written in Japanese.

Optional scripts

Disable LEDs

One time

#!/bin/bash -e
echo none | sudo tee /sys/class/leds/led0/trigger > /dev/null # disable green led
echo none | sudo tee /sys/class/leds/led1/trigger > /dev/null # disable red led
echo 0 | sudo tee /sys/class/leds/led1/brightness > /dev/null

Forever

#!/bin/bash -ue
GREEN_LED_CMD="dtparam=act_led_trigger=none
dtoverlay=pi3-act-led,activelow=on"

echo "${GREEN_LED_CMD}" | sudo tee -a /boot/config.txt > /dev/null
echo "dtparam=pwr_led_trigger=none,pwr_led_activelow=on" | sudo tee -a /boot/config.txt > /dev/null
