Icecast Streaming media server in IOCage Jail

Z

zader

Part I : Install update and mount dataset /playlist in icecast jail as /media/playlist

Host configuration:
iocage create -n "name.domain.local" -r latest vnet="on" allow_raw_sockets="1" boot="on" defaultrouter="10.100.10.1" ip4_addr="10.100.10.200/24" --thickjail
zfs create -o mountpoint=/playlist zpool/playlist
mkdir /zpool/iocage/jails/name.domain.local/root/media/playlists
iocage fstab -a name.domain.local /playlists /media/playlists nullfs rw 0 0
iocage console name

Everything else is done within the jail:
Update the Jail and install and configure portmaster
pkg
portsnap fetch extract
cd /usr/ports/ports-mgmt/portmaster
make install clean && rehash

configure /usr/local/etc/portmaster.rc
cat <<EOF > /usr/local/etc/portmaster.rc
PM_LOG=/var/log/portmaster.log
PM_NO_CONFIRM=pm_no_confirm
PM_DEL_BUILD_ONLY=pm_dbo
SAVE_SHARED=wopt
SAVE_SHARED=wopt
ALWAYS_SCRUB_DISTFILES=dopt
BACKUP=bopt

Part II : Install Icecast2

portmaster audio/icecast2
echo "icecast_enable="YES"" >> /etc/rc.conf
cd /usr/local/etc
cp icecast.xml.sample icecast.xml
vi icecast.xml
#1 change the following (clients is the total max clients, sources is the total number of stream)
Code: 
        <clients>100</clients>
        <sources>12</sources>
#2 change the default password (you will need for the ics configuration and admin page)
:%s/hackme/yourpassword/g
:%s/hackmemore/yourpassword/g
#3 towards the end uncomment and change the user/group
Code: 
    <security>
        <chroot>0</chroot>
        <changeowner>
            <user>icecast</user>
            <group>radio</group>
        </changeowner>
    </security>
</icecast>
:wq!

create and own the log file
mkdir /var/log/icecast
chown -R nobody:nogroup /var/log/icecast

start the icecast2 service
service icecast2 start
check the log for errors
tail /var/log/icecast/error.log

you should see something like
Code: 
INFO main/main Icecast 2.4.0 server started
INFO connection/get_ssl_certificate No SSL capability on any configured ports
INFO yp/yp_update_thread YP update thread started

checkout your new server at
http://localhost/:8000

Part III : Install Ices and prepare some media

portmaster [port] audio/ices [/port]
[cmd]pw groupadd radio && pw useradd radio -g radio –m
mkdir /var/log/ices
chown –R radio:radio /var/log/ices

Let's get some media ready. You can use what ever converter you like. I highly recommend getting poikosoft's ezcdda converter.. its well worth the few dollars and they have not charged for updates in decades. The registered version allows for fast mass conversion / ripping and burning.

www.poikosoft.com

MP3 Converter Software | FLAC to MP3, WAV to MP3 conversion optimized for best audio quality

Convert MP3, FLAC and all audio files to/from Apple Lossless, AAC, Opus, WAV, DSD, M4A, plus more audio formats. Supports over 60 media file formats. Converter FLAC to MP3 is optimized for highest audio quality.
www.poikosoft.com www.poikosoft.com

I also found it handy to set up a vsftp/smb or other shared volume for converting and transferring files. but that's optional

click on audio converter
drag and drop your mp3s from the top to the middle.

at the bottom right select:
.ogg Q10 44khz
output folder (point it to your playlist share)

once you have your music files converted

mkdir /media/playlist/rock
mv /convertedfiles/* /media/playlist/rock

You should now have ices installed and a folder of music to create a play list from.

Part IV : Creating playlists, xml configuration and making your own daemon

this section consists of 4 parts
I created a simple script to save you some time.. lets make a rock playlist. you will need to change the genere, name, password and bit rates etc.

pw groupadd radio && pw useradd radio -g radio –m
mkdir /var/log/ices
chown –R radio:radio /var/log/ices
chown -R radio:radio /home/radio
mkdir /home/radio/conf
cd /home/radio
vi build-playlist.sh
modify and paste.. (change the path to suit your needs)
Code: 
#!/bin/sh

cd /media/playlists/$1
find /media/playlists/$1 -depth -name "*.ogg" -print | sort --random-sort > /home/radio/conf/$1.txt

cat <<EOF > /home/radio/conf/$1.xml
<?xml version="1.0"?>
<ices>
    <background>1</background>
    <logpath>/var/log/ices</logpath>
    <logfile>$1.log</logfile>
    <loglevel>1</loglevel>
    <consolelog>0</consolelog>

    <pidfile>/home/radio/$1.pid</pidfile>

    <stream>
        <metadata>
            <name>$1</name>
            <genre>ROCK!</genre>
            <description>ROCK till U Drop</description>
        </metadata>

        <input>
            <module>playlist</module>
            <param name="type">basic</param>
            <param name="file">/home/radio/conf/$1.txt</param>
            <param name="random">1</param>
            <param name="restart-after-reread">1</param>
            <param name="once">0</param>
        </input>

        <instance>
            <hostname>name.domain.local</hostname>
            <port>8000</port>
            <password>PASSWORD</password>
            <mount>/$1.ogg</mount>
            <reconnectdelay>2</reconnectdelay>
            <reconnectattempts>5</reconnectattempts>
            <maxqueuelength>80</maxqueuelength>

            <encode>
                <nominal-bitrate>500000</nominal-bitrate>
                <samplerate>44100</samplerate>
                <channels>2</channels>
            </encode>
        </instance>
     </stream>
</ices>
EOF

:wq!
chmod +x build-playlist.sh

once your default template is created ..
./build-playlist.sh rock
this will search the directory /media/playlists/rock .. generate a text list of all the files in the directory .. then randomise the list and write it to the user radios home directory .. conf as rock.txt .. the ics configuration is written as rock.xml ..

if you make a a directory called /media/playlists/country . to add it use ./build-playlist.sh country

You should now have
/media/playlists/rock with some .ogg files
/home/radio/conf/rock.txt
/home/radio/conf/rock.xml
/home/radio/build-playlist.sh

the next step is to create a daemon (you can add this to the build-playlist script, but for sake of ease I'm going to split it up.. just change the demo "rock" to $1

cd /usr/local/etc/rc.d
vi rock
paste in the daemon template
Code: 
#!/bin/sh
#
# PROVIDE: rock
# REQUIRE: DAEMON icecast2
# BEFORE:  LOGIN
# KEYWORD: shutdown

. /etc/rc.subr

name="rock"
rcvar=rock_enable

command="/usr/local/bin/ices"
extra_commands="reload"
pidfile="/home/radio/rock.pid"
sig_reload="USR1"

load_rc_config "$name"
: ${rock_enable="NO"}
: ${rock_config="/home/radio/conf/super_rock.xml"}
: ${rock_flags="${super_rock_config}"}
: ${rock_user="radio"}
required_files="${rock_config}"

run_rc_command "$1"
:wq!
you should now have a "rock"daemon (you can search / replace rock and replace it with the $1 if you want to add this step to the first script)

finally we need to add it to rc.conf just like any other service
echo "rock_enable="YES"" >> /etc/rc.conf
service icecast2 start
service rock start

and your shiny new server should be running at

icecast2 should be installed with ices random playlists all working as services within the radio users home directory.. all nicely housed in iocage and updated each day / startup.

I also made another script that I added with a @restart cron tab to systematically start the streams.. (i found they try and start to fast sometimes)
you can crontab -e something like this.

Code: 
#!/bin/sh

# nightly/startup script

service icecast restart
sleep 3
rm -rf /home/radio/conf/*.txt
sleep 4
pkill -u radio

find /media/playlists/rock -depth -name "*.ogg" -print | sort --random-sort > /home/radio/conf/rock.txt
sleep 3
service rock start

I crontabed this script to run once per day and as a reboot.. so anything added to the playlist dataset is automatically updated, re-shuffled and restarted.

rock on and have fun
