Update a Centreon 22.10 platform

This chapter describes how to update your Centreon 22.10 platform (i.e. switch from version 22.10.x to version 22.10.y).

Perform a backup​

Make sure that you have fully backed up your environment for the following servers:

  • central server,
  • database server.

Update the Centreon central server​

Prerequisites​

If you have installed debuginfo packages (or dbgsym on Debian), remove them before updating your platform. You can reinstall them after the update.

dnf remove \
centreon-collect-debuginfo-22.04.0-13.el8.x86_64 \
centreon-clib-debuginfo-22.04.0-13.el8.x86_64 \
centreon-engine-extcommands-debuginfo-22.04.0-13.el8.x86_64 \
centreon-engine-daemon-debuginfo-22.04.0-13.el8.x86_64 \
centreon-broker-cbmod-debuginfo-22.04.0-13.el8.x86_64 \
centreon-broker-core-debuginfo-22.04.0-13.el8.x86_64 \

Then upgrade all the components with the following command:

dnf update centreon\*

    If the Centreon BAM module is installed, refer to the update procedure.

  6. Deploy the central's configuration from the Centreon web UI by following this procedure.

Finally, restart Broker, Engine and Gorgone on the central server by running this command:

systemctl restart cbd centengine gorgoned

Reinstall debuginfo or dbgsym packages (optional)​

If you uninstalled debuginfo or dbgsym packages before performing the update, you can reinstall them now.

Update extensions​

From Administration > Extensions > Manager, update all extensions, starting with the following:

  • License Manager,
  • Plugin Packs Manager,
  • Auto Discovery.

Then you can update all other commercial extensions.

Update the Remote Servers​

This procedure is the same as to update a Centreon central server.

At the end of the update, the configuration should be deployed from the central server.

Update the Pollers​

  1. Clean the cache:

    dnf clean all --enablerepo=*
  2. Then upgrade all the components with the following command:

    dnf update centreon\*

Accept the new GPG keys from the repositories as needed.

  1. Deploy the Poller's configuration from the Centreon web UI by following this procedure, and choose the Restart method for the Engine process.

  2. Finally, restart the Gorgone service if it is used on the Poller:

    systemctl restart centengine gorgoned
