Bonjour tous le monde !
Au fait je travail sur un projet de monitoring réseaux avec centreon 2.6.0 sur un serveur ubuntu 12.04 version desktop. mon soucis est que tout les services fonctionnent sauf le service centstorage qui parvient pas a se connecter a mysql a travers le socket.
Quelqu'un a une idee?
Merci! d'avance pour aide!

Salut,

Peux-tu fournir le message d'erreur exact que tu as?

Merci.

[TourePlus]

Ok voici mes fichiers de log quand je fais un tail -f:
1-Dans le log de centstorage j'ai :
MySQL error : cannot connect to database centreon: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (caller: centreon::script::centstorage:/usr/share/perl5/centreon/script/centstorage.pm:440)

2-Dans le log de centcore j'ai :
2015-06-25 18:23:14 - MySQL error : cannot connect to database centreon: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (caller: centreon::common::db:/usr/share/perl5/centreon/common/db.pm:266)

Bonjour,

As-tu installé/configuré MySQL ? (paquet mysql-server)

[TourePlus]

mysql:Je l'ai juste installer et j'ai placer cette ligne innodb_file_per_table=1 dans my.cnf. De quelle configuration parlez vous?

[supersnail]

Normalement ubuntu te demande de renseigner (si ma mémoire ne me joue pas des tours) ton mot de passe de connexion et autres...

Sinon ça fonctionne après un sudo service mysql start ? Tu peux montrer le contenu de ton /etc/mysql/my.cnf ?

[TourePlus]

Oui bien sur ça marche

# --print-defaults to see which it would actually understand and use.

Au fait j'avais commencer avec le couple nagios 4.0.8 et centreon 2.6.0 et c'est le meme message dans les fichiers de log
1-Dans le log de centstorage j'ai :
MySQL error : cannot connect to database centreon: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (caller: centreon::script::centstorage:/usr/share/perl5/centreon/script/centstorage.pm:440)

2-Dans le log de centcore j'ai :
2015-06-25 18:23:14 - MySQL error : cannot connect to database centreon: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) (caller: centreon::common::db:/usr/share/perl5/centreon/common/db.pm:266)

3-j'ai fais une capture d'ecran sur laquelle j'ai les messages: poller central not running et some database poller update are not active check your monitoring platform la voici:

[supersnail]

Bonjour,

C'est sûr que ça marche mieux quand on lance le service effectivement ... Il faut juste maintenant lancer le service au démarrage (et la t'aidera vu que j'ai plus la commande en tête comme j'utilise plus ubuntu)

Ensuite les balises CODE ne sont pas optionnelles, merci d'y penser à l'avenir (bouton # de l'éditeur).

[TourePlus]

OK! vraiment merci pour l'aide que vous m'apporter. Donc le fait que le poller soit en rouge ne pose pas problème? bien sur que quand je part dans Configuration ->Centreon-> Pollers, le poller is running est a YES ou bien c'est parce qu’il s'agit de nagios et de ndo?

[supersnail]

Bonjour,

Pour le coup je ne saurais pas répondre, mes compétences en nagios sont très limités (proches de la non-existence même), désolé
