Migration of a platform with the Poller Display

Migrating your Centreon central server

If the module centreon-poller-display-central-1.6.x is installed:

  1. Go to the Administration > Extensions > Modules menu and uninstall the centreon-poller-display-central.

  2. Remove the associated package:

    # yum remove centreon-poller-display-central

If your server uses the CentOS or Red Hat v7 operating system, refer to the update procedure to update your Poller Display server. Otherwise, refer to the migration procedure.

Note

If you use the Centreon EMS modules, you must update these repositories. Be sure to contact Centreon support and request new licenses.

Migrating a server from the Centreon Poller Display to Remote Server

  1. Go to the Administration > Extensions > Modules menu and uninstall the Centreon Poller Display module.

  2. If you installed the module using an RPM package, remove it with the following command:

    # yum remove centreon-poller-display

Note

If you use Centreon EMS modules, you must update the repositories. Be sure to contact your Centreon support and request new licenses.

  1. If your server uses the CentOS or Red Hat v7 operating system, refer to the update procedure to update your Poller Display server. Otherwise, refer to the migration procedure.

  2. Go to Administration > Extensions > Modules menu and install the centreon-license-manager module.

  3. Execute the following command:

    # /usr/share/centreon/bin/centreon -u admin -p centreon -a enableRemote -o CentreonRemoteServer -v @IP_CENTREON_CENTRAL

Note

Replace @IP_CENTREON_CENTRAL by the IP of the Centreon server seen by the Poller.

This command will enable Remote Server mode:

Starting Centreon Remote enable process:

  Limiting Menu Access...Success
  Limiting Actions...Done

  Notifying Master...Success

  Set 'remote' instance type...Done

  Centreon Remote enabling finished.

  1. Add rights to centreon database user to use LOAD DATA INFILE command:

    # mysql -h <database_server_address> -u root -p
MariaDB [(none)]> GRANT FILE on *.* to 'centreon'@'<remote_server_ip>';

  2. Exchange the SSH key. If you do not have a private SSH key for the Centreon user on the central server:

    # su - centreon
$ ssh-keygen -t rsa

Copy this key to the new server:

# su - centreon
$ ssh-copy-id -i .ssh/id_rsa.pub centreon@IP_POLLER
  1. On the Centreon Central server, edit all pollers and attach them to the Remote Server using the selection list.

Note

Remember to generate the configuration for your Remote Server.

Note

A Centreon Remote Server is self-administered. Thus, the configuration of the LDAP directory, users and ACLs are specific to this server and must be configured through the Administration menu.
