Using Centreon el7 ISO¶
This process is identical to the one used for installing the Central Server from a Centreon ISO file.
Refer to the documentation: installation
Instead of choosing Central with database, you will select Poller and click Done. Please see the sizing guidelines for the poller server located here.
Exchanging SSH Keys¶
Communication between a central server and a poller server is done through SSH.
You need to exchange SSH keys between the servers.
If you do not have any private SSH keys on the central server for the centreon user:
# su - centreon $ ssh-keygen -t rsa
Hit enter when it prompts for a file to save the key to use the default location, or, create one in a specified directory. Leave the passphrase blank. You will receive a key fingerprint and a randomart image.
Generate a password for the centreon user on the new server:
# passwd centreon
Copy this key on to the new server:
# su - centreon $ ssh-copy-id -i .ssh/id_rsa.pub centreon@IP_NEW_SERVER
Configuring a new poller in Centreon¶
As of Centreon version 18.10, a new wizard has been added for defining a new poller on the Centreon platform.
You also have the option of adding a new poller manually, but we recommend using the following procedure.
Go to the Configuration > Pollers menu and click on Add server with wizard to configure a new poller.
Select Add a Centreon Poller and click on Next:
Type in the name, the IP address of the poller and IP address of the Central Server. Click on Next:
The IP address of the poller is the IP address or the FQDN used to access this poller from the Central Server.
The IP address of the Central Server is the IP address or the FQDN used to access the Central Server from the poller.
If you want to link the poller to the Centreon Server, click on Apply:
Otherwise, if you want to link the poller to an existing Centreon Remote Server, select one from the list. Then click Apply:
If you want to change the direction of the flow between the Centreon Server (or the Remote Server and the Poller, check the Advanced: reverse Centreon Broker communication flow checkbox. In this case, it will be necessary to export the configuration of the collector as well as the server to which it will be attached.
In a few seconds the wizard will configure your new poller.
Go to the Quick Start chapter to configure your first monitoring.
