Depuis la compatibilité de Centreon UI 2.6.0 avec PHP 5.4, installer Centreon est devenu un jeu d’enfant, enfin, presque… Cette article présente l’installation d’une supervision Nagios en utilisant les paquets Debian et Centreon 2.6.0. Nous utiliserons le broker Centreon pour faire le lien entre le moteur Nagios et l’interface Web Centreon.
L’installation est réalisée avec la version Wheezy de Debian. Il est possible d’utiliser la dernière version Jessie, j’indique les modifications à réaliser.
Attention, cette solution devient de plus en plus obsolète, Nagios n’étant plus proposé dans le choix du moteur dans l’interface de Centreon depuis la version 2.6.1.
1 – Installation de Nagios
2 – Installation de Centreon-Broker
3 – Installation du protocole SNMP
4 – Installation de Centreon UI
5 – Installation en mode Web
6 – Configuration des services

Installation de Nagios
L’installation de Nagios est « on ne peut plus simple ». Lancez la commande suivante :
# aptitude install nagios3
Le programme d’installation demande le mot de passe de nagiosadmin pour l’interface Web.
Confirmez.
L’installation terminée, votre supervision est opérationnelle. Lancez l’url suivante http://IP_du_Nagios/nagios3. Saisissez le nom de l’utilisateur nagiosadmin ainsi que son mot de passe associé et vous aurez la vue suivante en sélectionnant Current Status / Services
.
Installation de Centreon-Broker
L’équipe de Centreon a développé son propre broker plus modulaire et plus performant que celui proposé par Nagios, NDOutil. Il est depuis peu compatible avec Nagvis grâce à un connecteur spécifique. Actuellement, Centreon-Broker est à la version 2.8.2. Elle est comptatible avec la version de Centreon 2.6x. Les installations de Centreon-Broker 2.4x à 2.6x sont pratiquement identiques.
Ce chapitre présente l’installation de Centreon-broker version 2.8, c’est la suite pour l’installation finale de Centreon 2.6.x. Nous installerons la dernière version 2.8.2.
Pré requis
Tout d’abord, Il faudra créer un groupe système et un utilisateur système centreon-broker. Ceci est obligatoire pour installer l’interface Web de Centreon.
# groupadd -g 6002 centreon-broker # useradd -u 6002 -g centreon-broker -m -r -d /var/lib/centreon-broker -c "Centreon-broker Admin" centreon-broker
# aptitude install build-essential cmake librrd-dev libqt4-dev libqt4-sql-mysql libgnutls-dev lsb-release -y
# cd /usr/local/src # wget https://s3-eu-west-1.amazonaws.com/centreon-download/public/centreon-broker/centreon-broker-2.8.2.tar.gz # tar xzvf centreon-broker-2.8.2.tar.gz # cd /usr/local/src/centreon-broker-2.8.2/build/

# make # make install
# update-rc.d cbd defaults
L’installation de Centreon-Broker est terminée, il faut passer à l’installation de Centreon. Si vous n’avez pas configuré SNMP, il est temps de le faire.
.
Installation du protocole SNMP
Pré requis
Installons les paquets supplémentaires.
# aptitude install snmp snmpd libnet-snmp-perl libsnmp-perl -y
Paramétrages
Pour le fonctionnement du SNMP, modifiez le fichier /etc/snmp/snmpd.conf
# vim /etc/snmp/snmpd.conf agentAddress udp:localhost:161 rocommunity public localhost
Pour éviter d’avoir un deamon snmpd trop bavard, (réduction des logs), et pour recevoir les traps modifier le fichier /etc/default/snmpd
# vim /etc/default/snmpd # snmpd options (use syslog, close stdin/out/err). SNMPDOPTS='-LS4d -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid'
# aptitude install snmp-mibs-downloader -y # ln -s /usr/share/mibs/ /usr/share/snmp/mibs
Modifiez le fichier /etc/default/snmpd
# vim /etc/default/snmpd #mibs ALL export MIBDIRS=/usr/share/snmp/mibs export MIBS=ALL
# service snmpd restart
# snmpwalk -c public -v 2c localhost
Vous devez obtenir une très longue liste d’OID SNMP. Seul bémol, les OID de type HrSWInstalled (.1.3.6.1.2.1.25.6) ne sont pas pris en compte. C’est gênant pour certains plugins fournis par Centreon. Je n’ai pas trouvé la solution pour pallier ce problème.
.
Installation de Centreon UI
Tout d’abord, Il faudra créer un groupe et un utilisateur centreon
# groupadd -g 6000 centreon # useradd -u 6000 -g centreon -m -r -d /var/lib/centreon -c "Centreon Admin" centreon
# aptitude install sudo tofrodos bsd-mailx lsb-release mysql-server libmysqlclient-dev apache2 apache2-mpm-prefork php5 php5-mysql php-pear php5-ldap php5-snmp php5-gd rrdtool librrds-perl libconfig-inifiles-perl libcrypt-des-perl libdigest-hmac-perl libdigest-sha-perl libgd-gd2-perl php5-sqlite -y
# cd /usr/local/src # wget https://s3-eu-west-1.amazonaws.com/centreon-download/public/centreon/centreon-2.6.0.tar.gz # tar xzf centreon-2.6.0.tar.gz # cd centreon-2.6.0
./install.sh -i

Installation en mode Web
Avec Debian 8.0, il faut autoriser la configuration Centreon pour le serveur Web Apache
# a2enconf centreon.conf # service apache2 reload
Utilisez un navigateur internet récent et saisissez l’url suivante :
http://IP_du_server/centreon/
Démarrage de l’installation Web, cliquez sur “Next”
Validation des dépendances, cliquez sur “next”.
Nous choisirons comme moteur de supervision nagios. Saisissez les chemins ci-dessous.
Nagios directory : /usr/share/nagios3 Nagiostats binary : /usr/sbin/nagios3stats Nagios image directory : /usr/share/nagios3/htdocs/images Embedded Perl initialisation file : /usr/lib/nagios3/p1.pl
Cliquez sur Next. Auparavant, il faudra créer le dossier /var/log/centreon-broker et donner la permission au processus centengine d’écrire le fichier de statistique.
# mkdir /var/log/centreon-broker # chown centreon-broker:centreon-broker /var/log/centreon-broker # chmod 775 /var/log/centreon-broker # chmod 775 /var/lib/centreon-broker
Nous choisirons comme broker centreon-broker. Saisissez les chemins ci-dessous.
Centreon Broker etc directory: /etc/centreon-broker
Centreon Broker module (cbmod.so): /usr/lib/centreon-broker/cbmod.so
Centreon Broker log directory: /var/log/centreon-broker
Retention file directory: /var/lib/centreon-broker
Centreon Broker lib (*.so) directory: /usr/share/centreon/lib/centreon-broker
Cliquez sur Next
Création du user “Administrateur”, admin et son mot de passe. Saisir une adresse valide pour l’email. Cliquez sur Next.
Définir les Accès MySQL, le mot de passe de MySQL. Laisser les noms de base par défaut CENTREON, CENTSTORAGE et CENTSTATUS. Saisir le mot de passe pour ces bases de données. Avant de cliquez sur Next, modifiez le fichier de configuration de MySql /etc/mysql/my.cnf. Ajoutez la ligne suivante.
# vim /etc/mysql/my.cnf innodb_file_per_table=1
# service mysql restart
Cliquez sur Next
Cliquez sur Next
Fin de l’installation, cliquez sur Finish
Vous devriez avoir cette vue. Vous pouvez vous connecter à l’interface d’administration.
.
Configuration des services
# service centstorage start # service centcore start # service centreontrapd start # service apache2 reload
Connectez-vous à l’interface de Centreon. Sélectionnez le menu Configuration -> Monitoring Engines -> cgi. Modifiez la l’option Monitoring Engine process check command.
/usr/lib/nagios/plugins/check_nagios /var/log/nagios3/status.log 5 ”
Sélectionnez le menu Configuration -> Monitoring Engines -> main.cfg. Sélectionnez la configuration du moteur Nagios CFG 1. Modifiez l’option External Command File dans le premier onglet Files.
/var/lib/nagios3/rw/nagios.cmd
Pour évitez le message d’erreur lors de la génération des fichiers de configuration, modifiez les droits du dossier checkresults.
# chmod 775 /var/lib/nagios3/spool/checkresults
Pour générer la configuration, sélectionnez le menu Configuration / Monitoring Engines
# service cbd start
Au bout de quelques secondes, vous devriez voir apparaître les hôtes et services dans la barre d’état en haut à droite.
Voici la page des services en état pending. Toutefois l’hôte est en alerte car le plugin check_icmp ne peut être utilisé par l’utilisateur nagios. Il faut rajouter des droits supplémentaires pour deux plugins.
# chmod u+s /usr/lib/nagios/plugins/check_dhcp # chmod u+s /usr/lib/nagios/plugins/check_icmp
Votre serveur de supervision est en état de fonctionnement.
Gé-ni-al !!!
Tout simplement !
Un grand merci
