Version: 22.10

Upgrading the extension

From Centreon 24.10, MAP Legacy will no longer be available. If you are still using MAP Legacy, you will need to migrate to MAP. See MAP Legacy end of life.

This chapter describes how to upgrade your Centreon MAP (Legacy) extension. This is done by upgrading the four main components:

  • Centreon MAP (Legacy) server
  • Centreon MAP (Legacy) web interface and its widget
  • Desktop client (automatically updated)
  • MariaDB database.

Prerequisites​

Before upgrading Centreon MAP (Legacy) server, we highly recommend performing a MariaDB dump (backup) of your centreon_studio database. This will allow you easily to roll back to the previous state if necessary.

Be sure to read the release notes for an explanation of features, fixes and custom procedures.

When you're upgrading to a new major or minor version (i.e:A.B.x with A or B that changes) you need to contact our Support service to retrieve the new repository.

Update the RPM signing key​

For security reasons, the keys used to sign Centreon RPMs are rotated regularly. The last change occurred on October 14, 2021. When upgrading from an older version, you need to go through the key rotation procedure, to remove the old key and install the new one.

Step 1: Centreon MAP (Legacy) server​

If you are still running version 4.0.X, you must first install and run the server in version 4.1.X before upgrading to the latest version.

Java version requirement​

Ensure a version of Java 17 (or 18) is installed before you start the procedure.

  • If you need to check the Java version, enter the following command:
java -version

  • If you need to upgrade the Java installation to Java 17 (or 18), go to the Oracle official download page.

  • If several Java versions are installed, you need to activate the right version. Display the installed versions using the following command and select the Java 17 (or 18) version:

sudo update-alternatives --config java

Then restart the service:

systemctl restart centreon-map
  • If you need to use your platform in HTTPS, you will have to generate a keystore file for the Java 17 (or 18) version (see the procedure).

Procedure​

Follow this procedure to upgrade your Centreon MAP (Legacy) server:

  1. Update the Centreon repository:
dnf install -y dnf-plugins-core
dnf config-manager --add-repo https://packages.centreon.com/rpm-standard/22.10/el8/centreon-22.10.repo

  1. Install Centreon Business repository, you can find it on the support portal.

  2. Update Centreon MAP (Legacy) server:

    dnf update centreon-map-server

  1. Enable and start centreon-map service:

    systemctl enable centreon-map
    systemctl start centreon-map

  2. This point only applies if you customized your centreon-map.conf configuration file. When upgrading your MAP (Legacy) module, the /etc/centreon-studio/centreon-map.conf file is not upgraded automatically: the new configuration file brought by the rpm does not replace the old file. You must copy the changes manually to your customized configuration file.

  • The old configuration file is renamed centreon-map.conf.rpmsave
  • The upgrade installs a new centreon-map.conf file.

Run a diff between the old and the new configuration files:

diff -u /etc/centreon-studio/centreon-map.conf /etc/centreon-studio/centreon-map.conf.rpmsave

For each difference between the files, assess whether you should copy it from centreon-map.conf.rpmsave to centreon-map.conf.

Step 2: Centreon MAP (Legacy) web interface​

dnf update centreon-map-web-client

Complete the upgrade:

  1. Go to Administration > Extensions > Manager.
  2. Search for Map web client.
  3. Click on the update button (module & widget parts).

Step 3: Centreon MAP (Legacy) desktop client​

If the user's computer has an online connection, the desktop client is automatically upgraded to the latest version that corresponds to the server.

Alternatively, the client can be downloaded through the menu Monitoring > Map and Desktop client button.

Please follow these recommendations to avoid the MAP desktop client running slowly after its upgrade.

Step 4: Update dialects in .properties files​

In the /etc/centreon-studio/centreon-database.properties and the /etc/centreon-studio/studio-database.properties files, replace MySQL5Dialect with MariaDB10Dialect.

This configuration also works with a MySQL database.

Step 5: MariaDB database​

Mistakes when editing configuration files can lead to malfunctions of the software. We recommend that you make a backup of the file before editing it and that you only change the settings advised by Centreon.

  1. Stop the centreon-map service:

    systemctl stop centreon-map

  2. Make sure you are using the correct version of MariaDB and update it if needed. See Upgrading MariaDB.

  3. If you have upgraded your Centreon platform to version 22.10, the new BBDO v3 protocol is enabled. You need to edit the following file to allow MAP to work properly: /etc/centreon-studio/studio-config.properties

    broker.pb.message.enabled=true

  4. Start the centreon-map service:

    systemctl start centreon-map
