Update a Centreon 22.04 platform

This chapter describes how to update your Centreon 22.04 platform (i.e. switch from version 22.04.x to version 22.04.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​

Update the Centreon solution​

Please make sure all users are logged out from the Centreon web interface before starting the update procedure.

  1. Clean the cache:

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

    dnf update centreon\*
  1. Now you can either perform the update:

    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.

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

    systemctl restart cbd centengine gorgoned

You can now move to the Update extensions step.

Finalize the update using the API endpoint​

  1. Log on to the central server through your terminal to continue the update process.

    You need an authentication token to reach the API endpoint. Perform the following procedure to get a token.

    In our case, we have the configuration described below (you need to adapt the procedure to your configuration).

    • address: 10.25.XX.XX
    • port: 80
    • version: 22.04
    • login: Admin
    • password: xxxxx
  2. Enter the following request:

    curl --location --request POST '10.25.XX.XX:80/centreon/api/v22.04/login' \
    --header 'Content-Type: application/json' \
    --header 'Accept: application/json' \
    --data '{
    "security": {
    "credentials": {
    "login": "Admin",
    "password": "xxxxx"
    }
    }
    }'

    This is how the result should look like:

    {"contact":{"id":1,"name":"Admin Centreon","alias":"admin","email":"admin@localhost","is_admin":true},"security":{"token":"hwwE7w/ukiiMce2lwhNi2mcFxLNYPhB9bYSKVP3xeTRUeN8FuGQms3RhpLreDX/S"}}
  3. Retrieve the token number to use it in the next request.

  4. Then enter this request:

    curl --location --request PATCH 'http://10.25.XX.XX:80/centreon/api/latest/platform/updates' \
    --header 'X-AUTH-TOKEN: hwwE7w/ukiiMce2lwhNi2mcFxLNYPhB9bYSKVP3xeTRUeN8FuGQms3RhpLreDX/S' \
    --header 'Content-Type: application/json' \
    --data '{
    "components": [
    {
    "name": "centreon-web"
    }
    ]
    }'
  5. This request does not return any result. To check if the update has been successfully applied, read the version number displayed on the Centreon web interface login page.

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

    systemctl restart cbd centengine gorgoned

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 yum cache:

    yum clean all --enablerepo=*
  2. Upgrade all the components with the following command:

    yum update centreon\*

    Accept the new GPG keys from the repositories as needed.

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

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

    systemctl restart centengine gorgoned
