Démarrage de la supervision

Cette nouvelle version de Centreon a changé son gestionnaire de tâches en passant de Centcore à Gorgone.

Il faut donc arrêter le service Centcore et démarrer le nouveau gestionnaire de tâches :

[root@vm-centreon ~]# systemctl stop centcore
[root@vm-centreon ~]# systemctl disable centcore

Lancer le nouveau service de gestionnaire de tâches :

[root@vm-centreon ~]# systemctl enable gorgoned

Mise à jour MariaDB 10.1 vers 10.2

Centreon 20.04.0 utilise la version 10.3. Il faut donc mettre à jour MariaDB.

Pour connaître la version, connectez-vous à MariaDB : Server version : 10.1

[root@vm-centreon ~]# mysql -u root
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 18865
Server version: 10.1.38-MariaDB MariaDB Server

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

MariaDB [(none)]>

Remarque : comme indiqué sur la doc Centreon et sur la doc officielle, il faut mettre à jour MariaDB en passant par chacune des versions.

  • Update MariaDB 10.1 vers 10.2
  • Update MariaDB 10.2 vers 10.3

Avant de réaliser cette opération, éditez le fichier suivant : /etc/my.cnf.d/centreon.cnf

[root@vm-centreon ~]# nano /etc/my.cnf.d/centreon.cnf

Supprimer le paramètre : innodb_additional_mem_pool_size

#
# Custom MySQL/MariaDB server configuration for Centreon
#
[server]
innodb_file_per_table=1

open_files_limit = 32000

key_buffer_size = 256M
sort_buffer_size = 32M
join_buffer_size = 4M
thread_cache_size = 64
read_buffer_size = 512K
read_rnd_buffer_size = 256K
max_allowed_packet = 8M

# For 4 Go Ram
#innodb_additional_mem_pool_size=512M
#innodb_buffer_pool_size=512M

# For 8 Go Ram
#innodb_additional_mem_pool_size=1G
#innodb_buffer_pool_size=1G

Depuis la version MariaDB 10.2, ce paramètre n’est plus utilisé.

Arrêter le service MariaDB :

[root@vm-centreon ~]# systemctl stop mariadb

Désinstaller la version actuelle 10.1 :

[root@vm-centreon ~]# rpm --erase --nodeps --verbose MariaDB-server MariaDB-client MariaDB-shared MariaDB-compat MariaDB-common

C’est terminé. Vérifie que tout fonctionne :

Centreon Events View

Remarque : pour mettre à jour un collecteur distant, répétez l’opération (sans mise à jour via l’interface web).

A ne pas oublier :

  • Vérifiez le bon fonctionnement de votre serveur : Administration > Statut de la plateforme > Statistiques du broker
  • Activer la sauvegarde de Centreon : Administration > Paramètres > Backup
  • Vérifiez l’état de votre collecteur : Configuration > Collecteurs

Supervision des systèmes & Réseaux

Mes articles sur la supervision avec Centreon :

Certaines applications/serveurs nécessitent l’installation d’un client/module sur le serveur Centreon.

    Bonjour,

    merci pour ces super tutos!

    Je suis passé de la version 19 à la 20.04 sans problème, tout est remonté.
    En revanche je viens d’essayer d’ajouter des services à monitorer et là j’ai des messages UNKNOWN: Can’t construct cache…
    J’ai ajouté centreon-gorgone dans le groupe centreon-engine mais rien a faire..
    Une idée?
    merci par avance

    J’étais en 19.10.10 pour centreon et en 10.1 pour MariaDB

    Bonjour,

    J’ai suivi les étapes de migration, mais j’ai un effet imprévu.
    Avant de commencer le chapitre “Mise à jour MariaDB 10.1 vers 10.2” tout fonctionnait correctement j’étais bien en version 20.04
    Sauf qu’apres avoir mis a jour MariaDB en suivant les etapes je me retrouve avec un centreon en 18.10.3 (que je n’ai jamais eu)
    Et j’ai beau faire une mise a jour centreon ça ne change pas.

    Une idée ?

      Bonjour Kevin,
      Tu étais sous quelle version avant ?
      Ici, c’est une mise à jour et non une migration d’une ancienne version !
