Upgrade the extension

When updating from version < 18.10 to a version >= 18.10, you need to

The upgrade of Centreon MBI consists of four steps:

  • Updating the repository
  • Updating the extension interface
  • Updating the reporting server
  • Updating the MariaDB database

Prerequisites​

Upgrade your central server​

See Introduction to upgrade.

Step 1: Update the repository​

When you upgrade from a previous major version to 26.10.x, you first need to update the repository on your Central & Reporting servers.

You will find the new "Business" repository on the "Repositories" page in your Centreon Support account.

On the reporting server, you also need to install the 26.10 standard repository:

dnf install -y dnf-plugins-core
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/26.10/el9/centreon-26.10.repo
dnf clean all --enablerepo=*

Step 2: Upgrade the extension interface​

  1. Update the package, run the following commands:
dnf clean all
dnf update centreon-bi-server
  1. Update through the interface: Log on to the Centreon web interface, go to Administration > Extension > Manager and click the Update button to update the extension and the widgets.

Step 3: Upgrade the reporting server​

Java version requirement​

Version 26.10 requires Java 25. When upgrading the MBI packages, java (OpenJDK 25) is automatically installed as a dependency, if needed. The cbis service always uses /usr/lib/jvm/java-25-openjdk on Alma / RHEL / Oracle Linux and /usr/lib/jvm/java-25-openjdk-amd64 on Debian 13. Once the upgrade is complete, you can remove the Java 17 packages left over from version 25.10, if no other application on the server uses them.

Upgrade procedure​

Now you can start the upgrade process:

  1. Connect to your reporting server and stop the scheduler service (CBIS):

    systemctl stop cbis

  2. Then run the following commands:

dnf install -y https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
dnf clean all
dnf update -y centreon-bi\* centreon-perl-libs-common

  1. Start the scheduler service:

    systemctl start cbis

  2. Start and enable gorgoned:

    systemctl start gorgoned && systemctl enable gorgoned

Step 4: Upgrade the MariaDB database​

  1. Stop the cbis service:

    systemctl stop cbis

  2. See Upgrading MariaDB.

    On Debian 13, if the package asks whether to replace /etc/mysql/mariadb.conf.d/50-server.cnf, keep your currently installed version (answer N). The package version sets bind-address = 127.0.0.1, and the central server would then no longer be able to reach the reporting database.

  3. Check that MariaDB is running:

    systemctl is-active mariadb

    The command must return active. On Debian 13, also check that MariaDB still listens on all interfaces:

    grep "^bind-address" /etc/mysql/mariadb.conf.d/50-server.cnf

    The value must be 0.0.0.0. If it is 127.0.0.1, set it back to 0.0.0.0 and restart MariaDB with systemctl restart mariadb.

  4. Start the cbis service:

    systemctl start cbis
