Lainon Radio Setup

In this tutorial we're going to setup a web radio for lainons on a debian server VM, figuring out how barrucadu installed lainon.life by looking at his github repository.

Initial Setup

First let's clone the repository into /srv


root@lain:/srv# apt update -y ; apt upgrade -y ; apt install git net-utils vim -y

#for arch users: 
root@lain:/srv# pacman -Syyuu ; pacman -S git vim

root@lain:/srv# cd /srv
root@lain:/srv# git clone https://github.com/barrucadu/lainonlife

Once that's done we start to install the required dependencies:


root@lain:/srv# apt install curl mpd mpc alsa-utils nginx -y

#for arch users:
root@lain:/srv# pacman -S curl mpd mpc alsa-utils nginx -y

We're going to start with the nginx configuration:


root@lain:/srv# ls
lainonlife
root@lain:/srv# cd lainonlife/examples/
root@lain:/srv/lainonlife/examples# ls -l
total 12
-rw-r--r-- 1 root root 1944 Jul 11 22:11 icecast.xml
-rw-r--r-- 1 root root 1136 Jul 11 22:11 mpd-cyberia.conf
-rw-r--r-- 1 root root 1161 Jul 11 22:11 nginx.conf


root@lain:/srv/lainonlife/examples# cp nginx.conf /etc/nginx/sites-available/lainon.conf
root@lain:/srv/lainonlife/examples# cd /etc/nginx/sites-available/
root@lain:/etc/nginx/sites-available# rm default
root@lain:/etc/nginx/sites-available# rm ../sites-enabled/default
root@lain:/etc/nginx/sites-available# vim lain.conf

root@lain:/etc/nginx/sites-available# cat lain.conf
  server {
    listen 80 default_server;
    listen [::]:80 default_server;

    server_name lain.void.yt;
    root /srv/http;

    proxy_set_header        Host $host;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;
    proxy_set_header        X-Forwarded-Host $host;
    proxy_set_header        X-Forwarded-Server $host;
    proxy_set_header        Accept-Encoding "";

    # this is needed to let people ajax stuff from other sites.
    add_header 'Access-Control-Allow-Origin' '*';

    # this is very important!  if you don't set it, nginx will buffer
    # the proxied audio stream to disk and eat all your space!
    proxy_max_temp_file_size 0;

    location / {
      try_files $uri $uri/ @script;
    }

    # icecast
    location /radio/ {
      proxy_pass http://localhost:8000/;
    }

    # grafana
    #location /graphs/ {
    #  proxy_pass http://localhost:8001/;
    #}

    # backend
    location @script {
      proxy_pass http://localhost:8002;
    }
  }

root@lain:/etc/nginx/sites-available# ln -s /etc/nginx/sites-available/lain.conf /etc/nginx/sites-enabled/
root@lain:/etc/nginx/sites-available# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

So right here in the nginx config i changed the server_name to match the DNS i will give it, and i commented out the grafana block because i won't use it. Although we do need the @script backend and icecast. So now from here let's move on to icecast, we're going to clone it in /srv too:


root@lain:/etc/nginx/sites-available# cd /srv

root@lain:/srv/icecast-server# apt install vorbis-tools libvorbis-dev libxml2 libxml2-dev libxslt1.1 libxslt1-dev curl pkg-config dh-autoreconf -y

root@lain:/srv/icecast-server# source ~/.bashrc

Once it's done we should be able to get the icecast binary added to our PATH, and a sample config file in /usr/local/etc/:


root@lain:/srv/icecast-server# which icecast
/usr/local/bin/icecast

root@lain:/srv/icecast-server# ls /usr/local/etc
icecast.xml

Although barrucadu also left a sample config for us to use, so let's test it after we modify it to match our Icecast install's directory paths for /var/log/icecast, /srv/IcecastServer/admin/, and /srv/icecast-server/web/:


root@lain:/srv/icecast-server# mkdir /var/log/icecast
root@lain:/srv/icecast-server# ls -l /var/log/icecast /srv/icecast-server/admin/ /srv/icecast-server/web/

root@lain:/srv/icecast-server/conf# vim icecast.xml

Here i basically changed the hostname, the admin password and the icecast directory paths we mentionned earlier:

Below those you can also see that we will need to setup the mpd mountpoints later on. We now change the ownership of /var/log/icecast to nobody:nogroup

We can check that our icecast server is running on port 8000:

Now that's done, exit out of icecast with CTRL+C and let's configure mpd using barrucadu's sample config file:


root@lain:/srv/icecast-server/conf# cd ../..
root@lain:/srv# cd lainonlife/
root@lain:/srv/lainonlife# cd examples/
root@lain:/srv/lainonlife/examples# vim mpd-cyberia.conf	

First we setup the root directory for our music files in /srv/radio/music/cyberia/ and the /srv/radio/data/cyberia/playlists directory:


root@lain:/srv# mkdir -p /srv/radio/data/cyberia/playlists
root@lain:/srv# mkdir -p /srv/radio/music/cyberia/
root@lain:/srv/radio# tree .
.
├── data
│   └── cyberia
│       └── playlists
└── music
    └── cyberia

root@lain:/srv# mkdir -p  ~/.config/mpd/

root@lain:/srv# kill $(pidof mpd)
root@lain:/srv# cp /srv/lainonlife/examples/mpd-cyberia.conf ~/.config/mpd/mpd.conf
root@lain:/srv# mpd
	

Now basically we will put our music files into /srv/radio/cyberia/, and we can make playlists of it using ncmpcpp i will do it from my local machine since my debian VM is in the same local network as i am :

Now if we want to connec to the mpd server with ncmpcpp we need the mpd server to be bound to it's local ip address instead of it's localhost address, so let's change it and restart it:


root@lain:/srv/radio# vim ~/.config/mpd/mpd.conf	

root@lain:/srv/radio# cat ~/.config/mpd/mpd.conf
music_directory     "/srv/radio/music/cyberia"
playlist_directory  "/srv/radio/data/cyberia/playlists"

#bind_to_address     "127.0.0.1"
bind_to_address     "10.0.0.201"
port                "6601"

[...]

root@lain:/srv/radio# mpd

root@lain:/srv/radio# pidof mpd
23898

You can ignore the the stderr from mpd, mpd is anyway launched as you can see from the pidof command. Now that's done we can connect to it with ncmpcpp:


[ 10.10.14.8/23 ] [ /dev/pts/30 ] [~]

Reading configuration from /home/nothing/.config/ncmpcpp/config...

Now obviously there are no music files to play yet, so we need to add them to the server's /srv/radio/music/cyberia/ directory:




root@lain:/srv/radio/music/cyberia# apt purge youtube-dl -y #youtube-dl is severly outdated on debian's repositories

Now that's done, let's go back into ncmpcpp to make our playlist:


[ 10.10.14.8/23 ] [ /dev/pts/30 ] [~]
→ ncmpcpp -h 10.0.0.201 -p 6601
	
#once in ncmpcpp
#press 1 to get to the playlist tab

root@lain:~# mkdir ~/.config/ncmpcpp
root@lain:~# which ncmpcpp

#make sure that you have changed the 10.0.0.201 part to 127.0.0.1
#same goes for mpd:

#mpd is going to run in the background, so we can always return to it with # ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press q to exit ncmpcpp

We can verify our cyberia ogg output exists on port 8000 by launching icecast and using it to verify it:


root@lain:~# icecast -c /srv/icecast-server/conf/icecast.xml
[2021-07-12  09:25:43] WARN CONFIG/_parse_root Warning,  not configured, using default value "Earth".

Changed groupid to 65534.
Changed supplementary groups based on user: nobody.
Changed userid to 65534.

We can log into icecast using the admin:P@SSW0RD_FOR_ADM1N credentials we used earlier in the config:

Now we need to fix the fact that icecast doesn't detect our mountpoints:

First we fix the passwords in the mpd and icecast config files:


root@lain:~# vim ~/.config/mpd/mpd.conf
root@lain:~# cat ~/.config/mpd/mpd.conf

  format      "44100:16:2"
  always_on   "yes"
}
[...]

root@lain:~# vim  /srv/icecast-server/conf/icecast.xml


Next we restart mpd and icecast:


root@lain:~# systemctl restart mpd
root@lain:~# icecast -c /srv/icecast-server/conf/icecast.xml	

Now icecast doesn't pick up our ogg stream, so let's try out the mp3 one:


root@lain:~# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config


And as you can see on icecast's admin page we see that the mp3 output does get picked up:

You can also see it appear on icecast's public /status.xsl page:

And we can play the direct .m3u link to our VLC player:

And it works! now let's make sure that mpd is running on loop while shuffling the songs, from ncmpcpp you can press r for repeat mode, and z for random mode. After that's working, we need to setup the website itself.


root@lain:/srv/lainonlife# mkdir /srv/http/
root@lain:/srv/lainonlife# cp config.json.example config.json
root@lain:/srv/lainonlife# vim config.json
root@lain:/srv/lainonlife# cat config.json
{ "channels":
  {  "cyberia":    { "mpd_host": "localhost", "mpd_port": 6601, "description": "classic lainchan radio: electronic, chiptune, weeb" }
  }

, "template":
  { "default_channel": "cyberia"
  , "icecast_status_url": "/radio/status-json.xsl"
  , "icecast_stream_url_base": "https://lain.void.yt/"
  , "server_cost": 10.00
  , "currency_symbol": "€"
  }
}
	

For now we only have one channel, but later on we can always add more. Now let's edit build.sh to use our new config json file:


root@lain:/srv/lainonlife#cd frontend 
root@lain:/srv/lainonlife/frontend# vim build.sh
root@lain:/srv/lainonlife/frontend# cat build.sh
#!/usr/bin/env bash

if [ -z "$1" ]; then
    #./build.py ../config.json.example
    ./build.py ../config.json.example
else
    ./build.py "$1"
fi
	

Now that's done we can build the frontend assets:


#debian users:

apt install python3-pip virtualenv -y

#arch users:
pacman -S python-pip python-virtualenv
pip3 install future ; pip install future

root@lain:/srv/lainonlife/frontend# pip install jinja2
root@lain:/srv/lainonlife/frontend# pip3 install jinja2
root@lain:/srv/lainonlife/frontend# which virtualenv
/usr/bin/virtualenv

And it's all here! so let's copy it to the root of our webserver at /srv/http/


root@lain:/srv/lainonlife/frontend/_site# cd ..
root@lain:/srv/lainonlife/frontend# cp -r _site/* /srv/http/
	

now that's done, we need to run the backend bashscript called run.sh and we need to pass it a few environment variables as we run it:


root@lain:/srv/lainonlife/frontend# cd ..
root@lain:/srv/lainonlife# cd backend/

Now it seems we forgot to install prometheus on port 9090. So let's install it following a tutorial i already made here, obviously use an up to date release version of prometheus from their release pages here to this date, the latest version is 2-28.1:

And from here we can check if prometheus is running on the correct port:

Now that prometheus is running on port 9090 we can also setup grafana but we commented it out earlier. Let's run run.sh to see if it works this time:


root@lain:/etc/prometheus# cd /srv/lainonlife/backend/

This time around we don't have the missing prometheus errors, so let's check if the server is running properly, and let's restart it to run on port 8002 since we told nginx we would use it for the @script block:

Now let's check if it works properly in the browser on port 80:

We got some progress! However we need to correct a few things, first the background:

Let's upload a few backgrounds into /srv/http/backgrounds/:


root@lain:/srv/http# cd backgrounds/
root@lain:/srv/http/backgrounds# ls -l
total 4
-rw-r--r-- 1 root root 68 Jul 12 10:18 index.html
	
root@lain:/srv/http/backgrounds# wget https://wallpapercave.com/wp/wp6600388.jpg

root@lain:/srv/http/backgrounds# wget https://blog.nowhere.moe/wallpapers/joi1.png

root@lain:/srv/http/backgrounds# wget https://blog.nowhere.moe/wallpapers/wallpaper_blue_original.png

Now that we got some backgrounds we also need the missing /css/font-awesome.min.css in the root of the webdirectory:


root@lain:/srv/lainonlife/# cd /srv/http/css/
root@lain:/srv/http/css# wget https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css
	

Now we get some missing icons, however this is probably related to the fact that we're not accessing our lainradio server from the correct domain name lain.void.yt:

Now i intend to run this lain radio behind a reverse nginx proxy, so i'll set it up from main debian node:


root@home:~# curl ifconfig.me ; echo; ping lain.void.yt
86.243.158.34
PING void.yt (86.243.158.34) 56(84) bytes of data.
	

First we get the DNS to point to the right IP, i used a CNAME to point at my root domain's public IP, but you can also use an A record to specify which IP the subdomain / domain name should point to. Now on my main debian node i use acme.sh to get letsencrypt TLS 1.3 certificates, so let's get them after i make the reverse proxy nginx config:


root@home:/var/www/void.yt/config# cd /etc/nginx/sites-available/
root@home:/etc/nginx/sites-available# vim lain.void.yt.conf
	
root@home:/etc/nginx/sites-available# cat lain.void.yt.conf
upstream lainbackend {
        server 10.0.0.201:80;
}

server {
        listen 80;
        listen [::]:80;
        server_name lain.void.yt;
        return 301 https://$server_name$request_uri;
}

server {
        listen 443 ssl http2;
        listen [::]:443 ssl http2;
        server_name lain.void.yt;

        ssl_certificate_key /root/.acme.sh/lain.void.yt/lain.void.yt.key;

        ssl_protocols TLSv1.3 TLSv1.2;

        ssl_prefer_server_ciphers on;
        ssl_session_cache shared:SSL:10m;
        ssl_session_timeout 10m;
        ssl_session_tickets off;

        add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";

        location / {

                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "Upgrade";
        }
}

You can tweak it however you like it, then we enable the site and get the letsencrypt certificates:


root@home:/etc/nginx/sites-available# ln -s /etc/nginx/sites-available/lain.void.yt.conf /etc/nginx/sites-enabled/
root@home:/etc/nginx/sites-available# nginx -t
nginx: [emerg] BIO_new_file("/root/.acme.sh/lain.void.yt/fullchain.cer") failed (SSL: error:02001002:system library:fopen:No such file or directory:fopen('/root/.acme.sh/lain.void.yt/fullchain.cer','r') error:2006D080:BIO routines:BIO_new_file:no such file)
nginx: configuration file /etc/nginx/nginx.conf test failed
root@home:/etc/nginx/sites-available# systemctl stop nginx
root@home:/etc/nginx/sites-available# acme.sh --issue --standalone -d lain.void.yt -k 4096

[...]

[Mon 12 Jul 2021 12:08:38 PM CEST] Your cert is in  /root/.acme.sh/lain.void.yt/lain.void.yt.cer
[Mon 12 Jul 2021 12:08:38 PM CEST] Your cert key is in  /root/.acme.sh/lain.void.yt/lain.void.yt.key
[Mon 12 Jul 2021 12:08:38 PM CEST] The intermediate CA cert is in  /root/.acme.sh/lain.void.yt/ca.cer
[Mon 12 Jul 2021 12:08:38 PM CEST] And the full chain certs is there:  /root/.acme.sh/lain.void.yt/fullchain.cer
	

Once that's done we can reactivate nginx and see the result:


root@home:/etc/nginx/sites-available# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

root@home:/etc/nginx/sites-available# systemctl start nginx

Now we access our webservice and we see that the domain has been verified by letsencrypt, but we're still missing the song names: so let's take a look into the /srv/lainonlife/scripts/ directory:



root@lain:/srv/lainonlife/scripts# ls -lash
total 24K
4.0K drwxr-xr-x 2 root root 4.0K Jul 12 12:23 .
4.0K drwxr-xr-x 9 root root 4.0K Jul 12 10:05 ..
4.0K -rwxr-xr-x 1 root root 2.3K Jul 11 22:11 album_times.py
4.0K -rwxr-xr-x 1 root root  943 Jul 11 22:11 file-list.sh
8.0K -rwxr-xr-x 1 root root 4.5K Jul 11 22:11 schedule.py
	

Here we have some scripts we should run. An easy one is file-list.sh:


root@lain:/srv/lainonlife/scripts# ./file-list.sh

That script is there so we can get a list of files to use:

Next we need to figure out schedule.py:


root@lain:/srv/lainonlife/scripts# pip3 install docopt
root@lain:/srv/lainonlife/scripts# python3 schedule.py --host=127.0.0.1 6601

Now if this schedule.py script errors out, that's because it's looking for the Lainchan Radio Transitions album, so to make this script work, we need the aforementionned album containing some songs, so let's create it with tracks we put into /srv/radio/music/cyberia/transitions/:


root@lain:/srv/radio/music/cyberia# mkdir transitions
root@lain:/srv/radio/music/cyberia/transitions# apt install ffmpeg
	
root@lain:/srv/radio/music/cyberia/transitions# youtube-dl -x https://www.youtube.com/playlist?list=OLAK5uy_kBzNHyOb4LcpwQI-uca1LApynboNkEvAo --audio-format mp3

Now that we have our transition tracks let's add them to the correct album via ncmpcpp:

root@lain:/srv/radio/music/cyberia# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press 2 and u to update the database, and you will see the transitions directory appear:

#and in it we have our transition audio tracks:

#so let's add them to the correct playlist album:
#select the tracks with INSERT
#then press a to add them to the Lainchan Radio Transitions playlist:

#press 5 to go to the playlists and you should see that result:

#now add a few more albums just like we did previously 
#so that schedule.py has a few albums to cycle through and to put transitions in between:

root@lain:/srv/radio/music/cyberia# youtube-dl -x --audio-format mp3 https://www.youtube.com/playlist?list=PL9AnroPjNnk0ukW3RvRQlbxA6nsNjG_9k
root@lain:/srv/radio/music/cyberia# youtube-dl -x --audio-format mp3 https://www.youtube.com/playlist?list=PLEBA2CD188C3A8278
root@lain:/srv/radio/music/cyberia# youtube-dl -x --audio-format mp3 https://www.youtube.com/playlist?list=PL4D3810FF245A180B

#Each time make sure you add them to separate albums with ncmpcpp just like we previously did to keep things clean.


So right now i have 3 albums (playlists) and a transition playlist, now let's use schedule.py:


root@lain:/srv/lainonlife/scripts# ls -l
total 16
-rwxr-xr-x 1 root root 2334 Jul 11 22:11 album_times.py
-rwxr-xr-x 1 root root  943 Jul 11 22:11 file-list.sh
-rwxr-xr-x 1 root root 4631 Jul 12 12:48 schedule.py
root@lain:/srv/lainonlife/scripts# python3 schedule.py --host=127.0.0.1 6601
Traceback (most recent call last):
  File "schedule.py", line 168, in <module>
    schedule_radio(client)
  File "schedule.py", line 114, in schedule_radio
    album, album_dur = pick_album(client, target_dur)
  File "schedule.py", line 68, in pick_album
    album = all_albums[0]
IndexError: list index out of range

Apologies on my part, for MPD playlists are NOT albums, so we need to create albums for each artist:

To do that we can add id3 tags:


root@lain:/srv/lainonlife/scripts# apt install libid3-tools -y

#for arch users:
pacman -S id3lib id3v2

root@lain:/srv/lainonlife/scripts# which id3tag
/usr/bin/id3tag	

So with id3tag we're going to add the album tags to our mp3 files:


root@lain:/srv/radio/music# vim tagger.sh
	

Now before running it we're going to add a tag to one track and see if it works as intended:


cd cyberia/transitions/	
root@lain:/srv/radio/music/cyberia/transitions# ls -lash Coloris-YTY7UV6GpkM.mp3
2.5M -rw-r--r-- 1 root root 2.5M Sep 15  2019 Coloris-YTY7UV6GpkM.mp3

Now since this is a Transition track let's add the Lainchan Radio Transitions album tag to it:


root@lain:/srv/radio/music/cyberia/transitions# id3tag --album "Lainchan Radio Transitions" Coloris-YTY7UV6GpkM.mp3
+++ Album   = Lainchan Radio Transitions
Tagging Coloris-YTY7UV6GpkM.mp3: attempting v1 and v2, tagged v1 and v2
	

And when we check it inside of ncmpcpp we see the following after updating the database with u:


root@lain:/srv/radio/music/cyberia/transitions# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press u to update the database
#press 4 to goto the Media Library 

So right here we have been able to create an album thanks to the id3tag tool, now if you're a masochist you can go ahead and do that manually for every song, if you're like me and want to make things simpler, we can use a script. i place it into /srv/radio/music/ to tag the transition tracks:


root@lain:/srv/radio/music# vim tagger_transitions.sh
root@lain:/srv/radio/music# cat tagger_transitions.sh
#! /bin/bash

GREEN="\033[0;32m"
ORANGE="\033[0;33m"
RED="\033[0;31m"
NC="\033[0m"

echo -en "${GREEN}[+]${NC} Type the name of the channel directory (ex: cyberia): "
read channel
echo -en "${GREEN}[+]${NC} default album name: ${GREEN} Lainchan Radio Transitions"
album="Lainchan Radio Transitions"


#### First list the songs and ask if the user wants to add the album tag to them:

#change IFS
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

cd $channel/transitions
SONGS=*

for SONG in $SONGS ;
do
        echo -en "\n ${ORANGE}[+] $SONG${NC}"
done
cd ../..

#restore IFS
IFS=$SAVEIFS



echo -en "\n\n${GREEN}[+]${NC} add the ${RED}$album${NC} ${ORANGE}album${NC} tag to these songs ? (y/n)"
read choice


####### If user says 'y' then add the album tag to the selected songs:

if [ "$choice" == "y" ];
then
        echo 'yes'

        #change IFS
        SAVEIFS=$IFS
        IFS=$(echo -en "\n\b")

        cd $channel/transitions
        SONGS=*

        for SONG in $SONGS ;
        do
                echo -en "\n ${GREEN}[+] $SONG${RED} ADDING TAG: ${ORANGE}$album${NC}"
                id3tag  --album="\"$album\"" $SONG
        done
        cd ../..

        #restore IFS
        IFS=$SAVEIFS
else
        echo 'cancelling...'
fi

echo
exit

So for me this script works, make sure you place it in /srv/radio/music/ otherwise it will not work as intended.

Now to tag the mp3 files in /channel/songname.mp3 with their album names i made a different script in /srv/radio/music/tagger.sh, again make sure the location is correct otherwise it won't work either :


root@lain:/srv/radio/music# cat tagger.sh
#! /bin/bash

GREEN="\033[0;32m"
ORANGE="\033[0;33m"
RED="\033[0;31m"
NC="\033[0m"

echo -en "${GREEN}[+]${NC} Type the name of the channel directory (ex: cyberia): "
read channel
echo -en "${GREEN}[+]${NC} Type the name of the album: "
read album
echo -en "${GREEN}[+]${NC} Type the name of the regex to match the album: "
read regex


#### First list the songs and ask if the user wants to add the album tag to them:

#change IFS
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

cd $channel
SONGS=*$regex*

for SONG in $SONGS ;
do
        echo -en "\n ${ORANGE}[+] $SONG${NC}"
done
cd ..

#restore IFS
IFS=$SAVEIFS



echo -en "\n\n${GREEN}[+]${NC} add the ${RED}$album${NC} ${ORANGE}album${NC} tag to these songs ? (y/n)"
read choice


####### If user says 'y' then add the album tag to the selected songs:

if [ "$choice" == "y" ];
then
        echo 'yes'

        #change IFS
        SAVEIFS=$IFS
        IFS=$(echo -en "\n\b")

        cd $channel
        SONGS=*$regex*

        for SONG in $SONGS ;
        do
                echo -en "\n ${GREEN}[+] $SONG${RED} ADDING TAG: ${ORANGE}$album${NC}"
                id3tag  --album="\"$album\"" $SONG
        done
        cd ..

        #restore IFS
        IFS=$SAVEIFS
else
        echo 'cancelling....'
fi

echo
exit
	

This time we specify the channel, the album, and the regex that we will use to match the files to add the tag to:


root@lain:/srv/radio/music# ./tagger.sh
[+] Type the name of the channel directory (ex: cyberia): cyberia
[+] Type the name of the album: Pendulum - Hold your Color^C
root@lain:/srv/radio/music# ./tagger.sh
[+] Type the name of the channel directory (ex: cyberia): cyberia
[+] Type the name of the album: Infected Mushroom - Army Of Mushrooms
[+] Type the name of the regex to match the album: Infected

After adding the other albums we can check the result in ncmpcpp:


root@lain:/srv/radio/music# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press 2 to get to the browsing tab
#press u to update the database
#see the album tags appear:

#press 4 to get to the media library:


We also fix the missing fonts in /srv/http/fonts/

Now the fonts are fixed once we check them in the browser:

first edit : index.html had broken links to the radio:



root@lain:/srv/http# cat index.html  | grep void
    lain.void.yt 
const ICECAST_STREAM_URL_BASE = "https://lain.void.yt/radio/";
            <source src="https://lain.void.yt//cyberia.ogg" type="audio/ogg"/>
            <source src="https://lain.void.yt//cyberia.mp3" type="audio/mpeg"/>
          <a id="ogglink" href="https://lain.void.yt//cyberia.ogg.m3u">ogg</a> /
          <a id="mp3link" href="https://lain.void.yt//cyberia.mp3.m3u">mp3</a>
	
root@lain:/srv/http# vim index.html
root@lain:/srv/http# cat index.html  | grep void
    lain.void.yt 
const ICECAST_STREAM_URL_BASE = "https://lain.void.yt/radio/";

          <a id="mp3link" href="https://lain.void.yt/radio/cyberia.mp3.m3u">mp3</a>

Now the radio actually plays from the browser :

However the title of each track are still missing.

EDIT 2: figured out how to go around the schedule.py errors

"""Radio scheduling program.

Usage:
  schedule.py [--host=HOST] PORT

Options:
  --host=HOST  Hostname of MPD [default: localhost]
  -h --help    Show this text

Takes a port number, and does the following:

1. Sets the play order to normal, looping.
2. Clears all music before the cursor position in the playlist.
3. Appends a roughly three-hour block of music to the end of the playlist in this format:
   a. A transition track
   b. A full album
   c. Enough random tracks to make up the difference.

The new segment may be a little shorter if an exact fit is not possible, but in practice it will
be close.

Why do this?  Listening to entire albums in order is nice, as tracks in an album often build off
each other.  On the other hand, variety is also nice!

Editing schedule.py to fix the python errors now it can be used:


root@lain:/srv/lainonlife/scripts# python3 schedule.py --host=127.0.0.1 6601
"Cyberia"
"Infected Mushroom - Army Of Mushrooms"
"Lainchan Radio Transitions"
"Pendulum"
['"Cyberia"', '"Infected Mushroom - Army Of Mushrooms"', '"Lainchan Radio Transitions"', '"Pendulum"']
Transition: transitions/Destination Luna4-VGaQwDylJPM.mp3 (142s)
Album: "Pendulum" (8631s)
Tracks: #0 (0s)

Target duration: 1800s
Actual duration: 8773s
Difference: -6973s

Now another guess for the 'undefined' song names problem, i assume that it's the missing tag titles, so let's see if that's the case:


root@lain:/srv/radio/music/cyberia# id3tag --song "Pendulum - The Tempest" The\ Tempest\ -\ Pendulum\ \[HQ\]-uy-3tWaKyg8.mp3
+++ Song    = Pendulum - The Tempest
Tagging The Tempest - Pendulum [HQ]-uy-3tWaKyg8.mp3: attempting v1 and v2, tagged v1 and v2

root@lain:/srv/radio/music/cyberia# id3tag --song "Pendulum - The Other Side" Pendulum\ \- The\ Other\ Side\ -\ Pendulum\ \[HQ\]-z0hwFJ1rbbU.mp3
+++ Song    = Pendulum - The Other Side

root@lain:/srv/radio/music/cyberia# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press u to update database
	

Looks like we were right! What we were missing here was the song/title tags for each mp3 file. so let's make a script to automatically add all of them:


root@lain:/srv/radio/music# vim tagger_titles.sh
root@lain:/srv/radio/music# cat tagger_titles.sh
#! /bin/bash

GREEN="\033[0;32m"
ORANGE="\033[0;33m"
RED="\033[0;31m"
NC="\033[0m"

echo -en "${GREEN}[+]${NC} Type the name of the channel directory (ex: cyberia): "
read channel

#### First list the songs and ask if the user wants to add the album tag to them:

#change IFS
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")

cd $channel
SONGS=*

for SONG in $SONGS ;
do
        echo -en "\n ${ORANGE}[+] $SONG${NC}"
done
cd ..

#restore IFS
IFS=$SAVEIFS



echo -en "\n\n${GREEN}[+]${NC} add the filename as ${ORANGE}title${NC} tag to these songs ? (y/n)"
read choice


####### If user says 'y' then add the album tag to the selected songs:

if [ "$choice" == "y" ];
then
        echo 'yes'

        #change IFS
        SAVEIFS=$IFS
        IFS=$(echo -en "\n\b")

        cd $channel
        SONGS=*

        for SONG in $SONGS ;
        do
                echo -en "\n ${GREEN}[+] $SONG${RED} ADDING TITLE TAG: ${ORANGE}$SONG${NC}"
                id3tag  --song="\"$SONG\"" $SONG
        done
        cd ..

        #restore IFS
        IFS=$SAVEIFS
else
        echo 'cancelling....'
fi

echo
exit

Now that's done we update the database with ncmpcpp as usual:


root@lain:/srv/radio/music# ncmpcpp -h 127.0.0.1 -p 6601 -c ~/.config/ncmpcpp/config
#press u to update the database	

And there you go! We managed to make each file's name display.

Automation



So now that we know our webserver is working as intended, let's write systemd services to handle automatically mpd, icecast and the run.sh bashscript:



root@lain:~# icecast -c /srv/icecast-server/conf/icecast.xml

In essence we need a systemd service to make the root user run these 3 commands so let's make them one by one. First the icecast systemd service:


root@lain:/srv/radio/music# cd /etc/systemd/system/

root@lain:/etc/systemd/system# vim icecast.service

We do the same for the backend script run.sh used to run the radio itself:

Now that's done we're going to setup the systemd service for mpd, now i intend to make a multiple-channel setup so i will make mpd use the config file:


root@lain:/etc/systemd/system# vim mpd-cyberia.service
root@lain:/etc/systemd/system# cat mpd-cyberia.service

And that's it! We managed to create 3 independent systemd services that will run everytime the host boots up, ensuring that the radio stays up and running from the start automatically. Now that should already be done but make sure that nginx and prometheus' systemd services are enabled too:


root@lain:/etc/systemd/system# systemctl enable --now nginx
root@lain:/etc/systemd/system# systemctl enable --now prometheus

Multi-Channel + Album Ordering Setup



Before adding channels let's get a more organized music folder architecture:

Basically, for each channel, we're going to have a folder for each album, and inside of each album folder we're going to have our song files. And also let's not forget that we have our transition files in the transitions folder, we want to tag them correctly with Lainchan Radio Transitions special album name. So from here we proceed:

First i move all of my songs into folders:


  mkdir "Serial Experiments Lain OST"
  mkdir "Infected Mushroom - Army of Mushrooms"
  mkdir "Pendulum - In Silico"

  mv Infec* Infected\ Mushroom\ -\ Army\ of\ Mushrooms/
  mv Serial* Serial\ Experiments\ Lain\ OST/
  mv *Pendulum* Pendulum\ -\ In\ Silico/
  mv *pendulum* Pendulum\ -\ In\ Silico/
  mv Lain\'s\ Theme\ -\ Lain-o-cwuTmqz8c.mp3 Serial\ Experiments\ Lain\ OST/

And now that's done we're going to change our tagger script as follows:


root@lain:/srv/radio/music# vim tagger.sh
root@lain:/srv/radio/music# cat tagger.sh
#! /bin/bash

GREEN="\033[0;32m"
ORANGE="\033[0;33m"
RED="\033[0;31m"
NC="\033[0m"

echo -en "${GREEN}[+]${NC} Type the name of the channel directory (ex: cyberia): "
read channel


#### First list the songs and ask if the user wants to add the album tag to them:

#change IFS
SAVEIFS=$IFS
IFS=$(echo -en "\n\b")


ALBUMS="*"
cd $channel
for ALBUM in $ALBUMS ;
do
                echo -en "\n ${ORANGE}[+] $ALBUM${NC}"
                cd $ALBUM
                SONGS="*"
                for SONG in $SONGS;
                do
                        echo -en "\n ${GREEN} [+] $SONG${NC}"
                done
                cd ..
done
cd ..

#restore IFS
IFS=$SAVEIFS


echo -en "\n\n${GREEN}[+]${NC} add the ${RED}$album${NC} ${ORANGE}album${NC} tag to these ${GREEN}songs ${NC}? (y/n)"
read choice






####### If user says 'y' then add the album tag to the selected songs:
if [ "$choice" == "y" ];
then
        echo 'yes'
        #change IFS
        SAVEIFS=$IFS
        IFS=$(echo -en "\n\b")


        ALBUMS="*"
        cd $channel
        for ALBUM in $ALBUMS ;
        do
                echo -en "\n ${ORANGE}[+] $ALBUM${NC}"
                cd $ALBUM
                SONGS="*"
                for SONG in $SONGS;
                do
                        echo -en "\n ${GREEN} [+] $SONG${NC}"
                        if [ $ALBUM == "transitions" ];
                        then
                                id3tag  --album="Lainchan Radio Transitions" $SONG
                                id3tag  --song="\"$SONG\"" $SONG
                        else
                                id3tag  --album="\"$ALBUM\"" $SONG
                                id3tag  --song="\"$SONG\"" $SONG

                        fi
                done
                cd ..
        done
        cd ..
        #restore IFS
        IFS=$SAVEIFS

else
        echo 'cancelling....'
fi


echo
exit
	

Basically, this script goes into the channel/ directory, then goes into each album/ directory, and then will add the tags as follows: the filename.mp3 becomes the song's id3tag, and the song's album/ directory becomes the song's album id3tag. Which fits how we want our service to function. Once that's done we simply run the schedule.py script to schedule our songs once again after updating the database:


root@lain:/srv/radio/music# ./tagger.sh

root@lain:/srv/radio/music# ncmpcpp -h 127.0.0.1 -p 6601
#press u to update database
#press q to quit

root@lain:/srv/radio/music# python3 /srv/lainonlife/scripts/schedule.py --host=127.0.0.1 6601
"Infected Mushroom - Army of Mushrooms"
"Pendulum - In Silico"
"Serial Experiments Lain OST"
Lainchan Radio Transitions
['"Infected Mushroom - Army of Mushrooms"', '"Pendulum - In Silico"', '"Serial Experiments Lain OST"', 'Lainchan Radio Transitions']
Transition: transitions/In Time-8PmEsQY5rq4.mp3 (129s)
Album: "Serial Experiments Lain OST" (4057s)
Tracks: #18 (6581s)

Target duration: 10800s
Actual duration: 10767s
Difference: 33s

Now another thing we can do is run the schedule.py script automatically every 3 hours so that our songs are continuously being updated, we can do that with a cronjob:


root@lain:/srv/radio/music# crontab -e
no crontab for root - using an empty one

Select an editor.  To change later, run 'select-editor'.
  1. /bin/nano        ---- easiest
  2. /usr/bin/vim.basic
  3. /usr/bin/vim.tiny

Choose 1-3 [1]: 2


# m h  dom mon dow   command
0 */3 * * * python3 /srv/lainonlife/scripts/schedule.py --host=127.0.0.1 6601

:wq
	

Now in order to test our cronjob we can use cronitor:




[ lain ] [ /dev/pts/1 ] [~]
→ wget https://github.com/cronitorio/cronitor-cli/releases/download/28.8/linux_amd64.tar.gz

Now to test the cronjob we run cronitor select


root@lain:/srv/radio/music# cronitor select

✔ python3 /srv/lainonlife/scripts/schedule.py --host=127.0.0.1 6601

root@lain:/srv/radio/music#
	

And here we see that we have been able to successfully run the script through our cronjob, and the way we set it up makes it so schedule.py is being ran every 3 hours, that way it matches the 3 hours of audio it tries to queue. Now let's add another channel. To do that we need 3 things, a channel directory in /srv/radio/music/, another mpd service running on another port (i'll do ports 6601, 6602, 6603, 6604, etc) and to edit the website configuration config.json to let the clients choose which channel they want to listen to:


root@lain:/srv/radio/music# mkdir metal
root@lain:/srv/radio/music# cd metal
root@lain:/srv/radio/music/metal# mkdir "Rivers of Nihil - Where Owls Know My Name"
root@lain:/srv/radio/music/metal# mkdir "Behemoth - The Satanist"
root@lain:/srv/radio/music/metal# mkdir "Carnifex - Slow Death"
root@lain:/srv/radio/music/metal# mkdir "Rivers of Nihil - Monarchy"
root@lain:/srv/radio/music/metal# cd Rivers\ of\ Nihil\ -\ Where\ Owls\ Know\ My\ Name/
root@lain:/srv/radio/music/metal/Rivers of Nihil - Where Owls Know My Name#
root@lain:/srv/radio/music/metal/Rivers of Nihil - Where Owls Know My Name# youtube-dl https://www.youtube.com/playlist?list=PLEouLkiLHdSDIqsVoq7a9bJDifla6XNq9 -x --audio-format mp3
[youtube:tab] PLEouLkiLHdSDIqsVoq7a9bJDifla6XNq9: Downloading webpage
[download] Downloading playlist: Rivers Of Nihil - Where Owls Know My Name
[youtube:tab] playlist Rivers Of Nihil - Where Owls Know My Name: Downloading 10 videos

Now like this you can fill in each of your album folders just like we did for the cyberia channel, don't forget the transitions either:


root@lain:/srv/radio/music/metal# mkdir transitions
root@lain:/srv/radio/music/metal# youtube-dl LINK -x --audio-format mp3
	

once you filled up the channel directory with album directories, run the tagger:


root@lain:/srv/radio/music# ls -l metal/
total 40
drwxr-xr-x 2 root root 4096 Jul 13 11:34 'Behemoth - I Loved You At Your Darkest'

drwxr-xr-x 2 root root 4096 Jul 13 11:20  transitions
root@lain:/srv/radio/music# ./tagger.sh	

Once that's done we're going to make another mpd config for our second channel, my second channel's mpd config will be in /root/.config/mpd/metal.conf:


root@lain:~/.config/mpd# cat metal.conf
music_directory     "/srv/radio/music/metal"
playlist_directory  "/srv/radio/data/metal/playlists"
db_file             "/srv/radio/data/metal/db"
state_file          "/srv/radio/data/metal/state"

bind_to_address     "127.0.0.1"
#bind_to_address     "10.0.0.201"
port                "6602"

audio_output {
  name        "[mpd] metal (ogg)"

  type        "shout"
  encoder     "vorbis"
  host        "localhost"
  port        "8000"
  mount       "/mpd-metal.ogg"
  user        "source"
  password    "P@SSWORD"
  quality     "3"
  format      "44100:16:2"
  always_on   "yes"
}

audio_output {
  name        "[mpd] metal (mp3)"
  description "classic lainchan radio: electronic, chiptune, weeb"
  type        "shout"
  encoder     "lame"
  host        "localhost"
  port        "8000"
  mount       "/mpd-metal.mp3"
  user        "source"
  password    "P@SSW0RD"
  quality     "3"
  format      "44100:16:2"
  always_on   "yes"
}

audio_output {
  type "null"
  name "null"
}

 audio_output {
     type  "alsa"
     name  "alsa audio"
     mixer_type      "software"
 }

audio_output {
    type                    "fifo"
    name                    "my_fifo2"
    path                    "/tmp/mpd.fifo2"
    format                  "44100:16:2"
}

I also create the directories it requires for the playlists and database:


root@lain:~/.config/mpd# mkdir -p /srv/radio/data/metal/playlists/
root@lain:~/.config/mpd# cd /srv/radio/data/
root@lain:/srv/radio/data# tree .
.

│   ├── playlists
│   │   ├── cyberia.m3u

│   │   └── pendulum.m3u
│   ├── state
│   └── sticker.sql
├── metal
│   └── playlists
└── syslog

4 directories, 8 files
	

Now since we already made a systemd service to run the cyberia mpd process, let's make another one for the second channel:


root@lain:/srv/radio/data# cd /etc/systemd/system/
root@lain:/etc/systemd/system# ls -l | grep mpd
-rw-r--r-- 1 root root  334 Jul 12 23:19 mpd-cyberia.service
root@lain:/etc/systemd/system# cp mpd-cyberia.service mpd-metal.service

Now once that's done we can connect to it on port 6602:


root@lain:/srv/radio/data#  ncmpcpp -h 127.0.0.1 -p 6602
#press u to update database
#press 7 to go to the outputs
#press enter to activate the metal ogg and mp3 outputs

root@lain:/srv/radio/data#  ncmpcpp -h 127.0.0.1 -p 6602
#press enter to start playing the tracks
#press q to exit

Now that's done let's add another cronjob to make sure the tracks are constantly added every 3 hours for our second channel:


root@lain:/srv/radio/data# crontab -e
	
# m h  dom mon dow   command

Now that we finished our cronitor job for our second channel, we need to edit icecast.xml:


root@lain:/srv/radio/data# vim /srv/icecast-server/conf/icecast.xml

	

Once we add the following block we restart our icecast service:


root@lain:/srv/radio/data# systemctl restart icecast
root@lain:/srv/radio/data# systemctl status icecast
● icecast.service - Icecast systemd service with config in /srv/icecast-server/conf/icecast.xml

root@lain:/srv/radio/data#
	

Now if you do this you will probably see that icecast doesnt detect the mountpoints anymore, to fix that restart the mpd channels:


root@lain:/srv/radio/data# systemctl restart mpd-cyberia
root@lain:/srv/radio/data# systemctl restart mpd-metal
	

You can verify if it's working at localip:8000/admin/listmounts.xsl

Now we need to change config.json to include our second channel:


root@lain:/srv/lainonlife# ls -l

    { "cyberia":    { "mpd_host": "localhost", "mpd_port": 6601, "description": "classic lainchan radio: electronic, chiptune, weeb" }
    , "metal":       { "mpd_host": "localhost", "mpd_port": 6602, "description": "Death Metal, Deathcore, Black Metal" }}

  , "icecast_stream_url_base": "https://lain.void.yt/radio/"
  , "server_cost": 10.00
  , "currency_symbol": "€"
  }
}

Now since we modified the config file let's restart the lainradio service:


root@lain:/srv/lainonlife# systemctl restart lainradio.service
	
[ lain ] [ /dev/pts/0 ] [~]
→ vim /srv/lainonlife/scripts/restart-radio.sh

Now by default the radio.js file looks for the channel names by their ogg extention, so i modified it to look for mp3 instead, and we finally get the channels to be displayed:


root@lain:/srv/http/js# cat radio.js | grep mp3
            if(sname !== undefined && sname.startsWith("[mpd] ") && sname.endsWith(" (mp3)")) {

I changed it from ogg to mp3 because for some reason i can't get my .ogg output streams to work, but the mp3 ones work fine so we're using them instead:

And when we change channels we see that everything updates as intended:

So with the same process we can add other channels, each of them have a systemd mpd-channel.service file to launch a mpd process on a specific port (ex: 6603 with a mpd config at /root/.config/mpd/channel.conf, with a directory at /srv/radio/music/channel/of their own. Of course you need to edit /srv/lainonlife/config.json and icecast.xml with your changes everytime. and make sure that you have a cronjob running python3 /srv/lainonlife/scripts/schedule.py --host=127.0.0.1 6603 every 3 hours after you added the transition tracks just like for our previous 2 channels in order to keep the radios constantly updated with new albums / songs to play for the listeners.

here's the forked repository with all important files i edited here:

-mpd-cyberia.service
-lainradio.service

-schedule.py
