Dear

I did a fresh VMware 23.04 installation. I have 3 problems with this installation.
Error message :

  • Connection-Time : CRITICAL: Cannot connect: Access denied for user 'centreon-engine'@'localhost'
  • proc-rsyslogd : Number of current processes running: 0

  • proc-postfix : Number of current processes running: 0

     

Also, during server reboot, wait 30 minutes before data refresh. I think about first error message

 

Centreon also does not want to change the administrator password 

Thanks to help me

J'ai fait une nouvelle installation VMware 23.04. J'ai 2 porblèmes avec cette installation.
Message d'erreur 

  • Connection-Time : CRITICAL: Cannot connect: Access denied for user 'centreon-engine'@'localhost'
  • proc-rsyslogd : Number of current processes running: 0

  • proc-postfix : Number of current processes running: 0

Egalement, lors du redémarrage serveur, il faut attendre 30 minutes avant l'actualisation des données

Centreon ne veut pas non plus changer le mot de passe administrateur 

Merci de votre aide

Centreon also does not want to change the administrator password 

Thanks to help me

Hello @Cyrille , just solved it this by doing this:

  1. connect to mysql running “mariadb”
  2. SELECT contact_id, contact_name FROM centreon.contact; (to get the ID of the contact you want to reset the password)
  3. UPDATE contact_password SET password = md5('XXX') WHERE contact_id = XX;
  4. Voilà 😀

Hello,

Did you solve the problem for centreon-engine access denied?

I followed the doc to secure my install and I get the same messages.

No user called centreono-engine in MariaDB.

Thank you

Bonjour,

Avez-vous résolu le souci “access denied” pour l’utilisateur centreon-engine?

J’ai le même message après avoir suivi la doc pour sécuriser l’installation, et je n’ai pas d’utilisateur centreon-engine dans MariaDB.

Cela ressemble a un problème strictement système de Linux, mais je n’ai pas trouvé où modifier ça dans l’interface Web de centreon.

Merci

Hi,

I have the same problem : UNKNOWN: Cannot connect: Access denied for user 'centreon-engine'@'localhost'

The database’s user is centreon and not centreon-engine, where can we change this information ?

I’ve tried to add macros in the centreon host configuration MYSQLUSERNAME and MYSQLPASSWORD  but he keep centreon-engine @ localhost.

 

Thank’s for your help.

Now, im going to help in the forum.

I had the same problem, when you copy the configuration files, you overwrite the file that contain the password:

https://thewatch.centreon.com/platform-7/mariadb-access-denied-for-user-centreonatlocalhost-2439

to get around the problem:

CREATE USER 'centreon-engine'@'localhost' IDENTIFIED BY 'centreon';

GRANT ALL PRIVILEGES ON *.* TO 'centreon-engine'@'localhost' WITH GRANT OPTION;
