Musique automatique en boutique

Ci-dessous, les infos pour faire tourner automatiquement la musique en point de vente.

Installer mpg123 & alsa-utils

apt-get install mpg123

apt-get install alsa-utils

Le script

#!/usr/bin/zsh

DATE=`date +"%H%M"`

MUSIQUE=`ps -ef | grep mpg123 | grep -v grep | awk '{print $2}'`

if [ $DATE -lt 1100 ]
then
if [ $MUSIQUE ]
then
#                echo ca tourne alors que la boutique est fermee donc on va killer;
kill -TERM `ps -ef | grep mpg123 | grep -v grep | awk '{print $2}'`;
else
#                echo ca tourne pas c donc ok;
fi
elif [ $DATE -gt 1930 ]
then
if [ $MUSIQUE ]
then
#                echo ca tourne alors que la boutique est fermee donc on va killer;
kill -TERM `ps -ef | grep mpg123 | grep -v grep | awk '{print $2}'`;
else
#                echo ca tourne pas c donc ok;
fi
else
# echo La boutique est ouverte;
# echo On verifie que la musique tourne bien sinon on la demarre;
if [ $MUSIQUE ]
then
#               echo ca tourne tout est ok;
else
#               echo ca tourne pas faut demarrer tout ca;
export LD_LIBRARY_PATH=/usr/lib:/usr/lib/mpg123;
mpg123 -Z /home/caisse/zique/*;
fi
fi

Ensuite, un crontab et c'est parti ...

Les musiques dont la diffusion est permise sont stockées sur le serveur principal place Saint Georges. Donc penser à faire un rsync sur les répertoires au moment de la config du crontab de la caisse.

Carte MegaRAID sur Debian Squeeze (MG Hybrid 2011 OVH)

Il y a deux jours, nous avons loué une nouvelle machine chez l'hébergeur OVH.

Cette dernière est équipé d'une carte RAID hardware MegaRAID.

La commande MegaCli qui permet de contrôler la carte et d'affiner les réglages est malheureusement très pauvrement documentée.
Voici quelques commandes de bases ...
