Nous installerons le moteur Centreon-Engine. La compilation ne prendra que six de minutes au lieu de 10 pour un PI 3, le Pi 4 gagne encore en puissance.

7 Pré Requis

Tout d'abord, Il faudra créer un utilisateur centreon-engine
sudo groupadd -g 6001 centreon-engine
sudo useradd -u 6001 -g centreon-engine -m -r -d /var/lib/centreon-engine -c "Centreon-engine Admin" centreon-engine

L'installation, au préalable, de Centreon Clib est obligatoire.
Il faut aussi installer des paquets supplémentaires.
sudo apt-get install libcgsi-gsoap-dev zlib1g-dev libssl-dev libxerces-c-dev -y

8 Installation

La dernière version stable est la 19.10.7. Téléchargez le binaire dans le dossier home et décompressez-le.
cd
wget http://files.download.centreon.com/public/centreon-engine/centreon-engine-19.10.7.tar.gz
tar xzf centreon-engine-19.10.7.tar.gz
cd centreon-engine-19.10.7

Préparons la compilation.
cmake  \
-DWITH_CENTREON_CLIB_INCLUDE_DIR=/usr/include \
-DWITH_CENTREON_CLIB_LIBRARY_DIR=/usr/lib \
-DWITH_PREFIX=/usr \
-DWITH_PREFIX_BIN=/usr/sbin \

Astuce pour la compilation
Pour accélérer le processus de compilation pour pouvez ajouter une directive de compilation afin d'autoriser des tâches simultanées. La bonne pratique est d'ajouter un argument correspondant au nombre de coeur + 1 :
make -j <nbr de coeur>+1

Avec cette directive, pour un raspberryPI 3+, la durée de compilation passe de 10 minutes à 4 minutes.
Ensuite compilons cette configuration et installons centengine, patientez une bonne dizaine de minutes.
make
sudo make install

Pour vérifier, avant de continuer, le bon fonctionnement de la librairie partagée, saisissez la commande suivante:
root@supervision:~# centengine -V

Mettre le service centenaire en démarrage automatique.
sudo systemctl enable centengine.service
sudo systemctl daemon-reload

L'installation de Centreon-Engine est terminée, il faut passer à l'installation des plugins.
