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

    > If you use Centreon EMS modules, you must update the repositories. Be sure to
    > contact your Centreon support and request new licenses.
  4. Go to Administration > Extensions > Modules menu and install the centreon-license-manager module.

  5. Enable the Remote Server option

    To transform the server into a Remote Server, connect to the server and execute following command:

    /usr/share/centreon/bin/centreon -u admin -p centreon -a enableRemote -o CentreonRemoteServer \
    -v '<IP_CENTREON_CENTRAL>;<not check SSL CA on Central>;<HTTP method>;<TCP port>;<not check SSL CA on Remote>;<no proxy to call Central>'
    • Replace <IP_CENTREON_CENTRAL> by the IP of the Centreon server seen by the poller. You can define multiple IP address using a coma as separator.

      To use HTTPS, replace <IP_CENTREON_CENTRAL> by https://<IP_CENTREON_CENTRAL>.

      To use non default port, replace <IP_CENTREON_CENTRAL> by <IP_CENTREON_CENTRAL>:<PORT>

    • For the <not check SSL CA on Central> option you can put 1 to do not check the SS CA on the Centreon Central Server if HTTPS is enabled, or put 0.

    • The <HTTP method> is to define how the Centreon Central server can contact the Remote server: HTTP or HTTPS.

    • The <TCP port> is to define on wich TCP port the entreon Central server can contact the Remote server.

    • For the <not check SSL CA on Remote> option you can put 1 to do not check the SS CA on the Remote server if HTTPS is enabled, or put 0.

    • For the <no proxy to call Central> option you can put 1 to do not use HTTP(S) proxy to contact the Centreon Central server.

    This command will enable Remote Server mode:

    • by limiting menu access,
    • by limiting possible actions,
    • by allowing the Central to connect to it,
    • by pre-registering the server to the Central.
    Starting Centreon Remote enable process:
    Limiting Menu Access... Success
    Limiting Actions... Done
    Authorizing Master... Done
    Set 'remote' instance type... Done
    Notifying Master...
    Trying host '10.1.2.3'... Success
    Centreon Remote enabling finished.
  6. Add rights to centreon database user to use LOAD DATA INFILE command:

    GRANT FILE on *.* to 'centreon'@'localhost';
  7. On the Centreon Central server, edit all pollers and attach them to the Remote Server using the selection list.

Remember to generate the configuration for your Remote Server.

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.
