Wonderradio and Arch install process documentation

# pacman -Syu
# reboot

# pacman -S sudo adduser tmux
# visudo
   enable sudo access for wheel group
   Save and exit with :wq
# adduser
   username: pi
   additional groups: audio video wheel
# exit

Login as pi, we dont have to login as root
again.

$ tmux
   I like using tmux when SSH'ing
# hostnamectl set-hostname wonderradio
# timedatectl set-timezone Region/City
Install the radio:

# pacman -S nginx php-fpm mariadb icecast
  mpd nodejs git
$ git clone https://github.com/daniel-j/wonder-radio
$ cd wonder-radio/
# cp nginx/nginx.conf /etc/nginx/nginx.conf
# nano /etc/nginx/nginx.conf
   Edit the path in the file, so that it
   points to the wonder-radio www folder.
   In my case it's this path:
   /home/pi/wonder-radio/www
   Press Ctrl+X and Y to save and exit.
# cp icecast/icecast.xml /etc/icecast.xml
# nano /etc/icecast.xml
   Replace all PASSWORD with actual password.
   I will use "twitch".
   Save and exit.
# systemctl enable nginx php-fpm mysqld icecast
# systemctl start nginx php-fpm mysqld icecast

$ mkdir ~/.mpd/
$ cp mpd/mpd.conf ~/.mpd/
$ nano ~/.mpd/mpd.conf
   Replace PASSWORD with actual password.
   You can also change audio quality
   in this file, and the title of the stream.
$ mkdir ~/music/
$ nano hidden.json
Put in the following content:
{
        "mysqlUsername": "root",
        "mysqlPassword": "twitch",
        "mysqlDatabase": "wonder-radio"
}
$ nano hidden.php
Put in the following content:
<?php
$mysqlHost = 'localhost';
$mysqlUser = 'root';
$mysqlPassword = 'twitch';
$mysqlDatabase = 'wonder-radio';
$mpdPassword = $mysqlPassword;
$adminPass = $mysqlPassword;
$localIcecastHost = '127.0.0.1';
$localIcecastPort = 8000;
$musicPath = "/home/pi/music/";

Let's make the MySQL database!

$ mysqladmin -u root password PASSWORD
$ mysql -u root -p
> create database `wonder-radio`;
> exit
$ mysql -u root -p "wonder-radio" < mysql/tables.sql

# nano /etc/php/php.ini
   Uncomment the line extension=pdo_mysql.so
# systemctl restart php-fpm
Make the style folder writeable for php
$ chmod -R 0777 www/style/

Now our radio is running!

Now it's a good thing we have tmux!
Run this command in one window:

$ mpd --verbose --no-daemon

This will start MPD, but not play any music.
We need to install the mpc command to
communicate with the MPD server.

Press Ctrl+B and then C to start a new
window in tmux. MPD is still running.

# pacman -S mpc
And now we must make some files executable.
$ chmod +x mpd-queue.sh mpd-update.sh server.js

Next we must install the nodejs mysql module.
$ npm install mysql

Try if the nodejs server is working:
$ node server.js
You should see a message saying:
"Unable to queue music.. Database empty?"

Press Ctrl+C to stop the server.
Let's add some music! I store my music on an
external medium (an old mp3 player).
The other way is to manually put files in
the ~/music/ folder. I can't remember the
fstab syntax so I'll just make a bash script.
$ mkdir ~/sansa/
# mount /dev/sda /home/pi/sansa -o rw,exec,uid=1000,gid=1000,dev
Make a new tmux window and go to your home dir
You should be able to browse the contents of
your external drive with ls ~/sansa/
I only want to add some folders to my radio,
so I will use symbolic links.
$ cd sansa/
$ ln -s ~/music/TO FROM
Check if it worked with:
$ ls ~/music/ -l
You should see your folders in lightblue.
Let's go to the radio in the browser. We want
to update the music database. Find the admin
login link, and login with your password.
Press "Update database".

Now we can start the nodejs server.
Press Ctrl+B P to get back to the previous
window.
$ node server.js

Yeah right, we forgot some stuff
Let's check the error.
Ya, I forgot the icecast files.
Derp......... well, i wrote over my local file
fixed. just ignore that
# cp icecast/listclients.xsl /usr/share/icecast/admin/listclients.xsl
# cp icecast/info_json.xsl /usr/share/icecast/web/
$ node server.js

SUCCESS
Well, forgot one detail, the stream URL is
wrong. Edit the file www/config.php

TODO:
  Automatic start of mpd, as user pi.
  Automatic start of the nodejs server.
  Mounting the storage with fstab.
  Tip: use systemd for starting services.

I will attempt to make it now though. :P
We'll copy a sample!

I commented out the "process.title = .." line
in server.js, and instead added the following
at the near top of the file:
process.title = "wonder-radio";

start.sh:
#!/bin/sh
sudo mount /dev/sda /home/pi/sansa -o rw,exec,uid=1000,gid=1000,dev
mpd --no-daemon --verbose &
node server.js &

/etc/systemd/system/wonder-radio@.service:
[Unit]
Description=Wonder-Radio
After=network.target

[Service]
Type=forking
User=%i
WorkingDirectory=/home/pi/wonder-radio/
ExecStart=/home/pi/wonder-radio/start.sh

[Install]
WantedBy=multi-user.target

Let's reboot!
SUCCESS!
