====== Installer une Webradio sous ubuntu ======

===== Introduction =====

Tout d'abord, j'ai choisi de faire une Webradio avec Ices et Icecast, car d'autres paquets ne prenaient pas en compte le format MP3 ce qui m'empêchais de lire mon flux via Itunes par exemple.

Sachez qu'en france c'est la SACEM qui gère les webradios, si vous voulez créer votre propre webradio et la diffuser sur internet vérifiez bien que le titre n'est pas déposé à la SACEM sinon les ennuis pourront vite arriver... sinon si vous souhaitez diffuser des titres déposé à la SACEM il vous faudra payer des droits de diffusion (environ 75€ HT/mois).

  * [[http://icecast.org/|Site de Ices et Icecast2]]

===== Installation =====

On installe les librairies MP3 et Icecast2

<code>apt-get install icecast2 libmp3lame0 libmp3lame-dev</code>

On installe Ices qui est un peu plus galère

<code>wget http://downloads.us.xiph.org/releases/ices/ices-0.4.tar.gz
tar -zxvf ices-0.4.tar.gz
cd ices-0.4
./configure --with-lame       ===>pour ma part 

configure: error: C++ preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

make && make install</code>   ===>make:  Pas de cibles spécifiées et aucun makefile n'a été trouvé. Arrêt.


<note tip>Vous noterez que l'on prends pas la dernière version de Ices, tout simplement parce que elle ne support pas le stream avec des MP3</note>

===== Configuration =====

==== Ices ====

Facilitons la configuration du fichier de configuration

<code>mkdir /etc/ices0
cd /etc/ices0
vim ices.conf.dist</code>

Puis mettez cela dans le fichier de configuration

==== Playlist ====

Bon maintenant le plus dur est fait vous devez vous demander a quoi ressemble une playlist ? exemple ci dessous

<code>

<note tip>Veuillez faire attention à mettre les noms corrects avec majuscules etc.</note>

===== Lancement =====

Redemarrage de IceCast2

<code>/etc/init.d/icecast2 restart</code>

Lancement de Ices

<code>ices -c /etc/ices0/ices.conf.dist</code>

Et voila les serveurs sont lancé normalement 

Pour aller sur le site de icecast (en local) il vous faut taper cette adresse http://monip:8000/ (http://127.0.0.1:8000/ si on est sur la machine où est installé le serveur) et pour acceder à la partie admin il vous faudra entrer les identifiants mit dans la config de Icecast2
