Using VM

Two pre-configured virtual machines are available on Centreon download web site.

These virtual machines are available in OVF (VMware) and OVA (VirtualBox) format.

Centreon Central server

Import

The first step is to import the OVF File. To do that go in File > Deploy OVF Template and choose your file. You can then follow different menus. Choices you made are linked to your VMWare configuration so it’s difficult to be more specific. Just be noticed that best practice are to used Thin Provision to keep some spaces in disk.

Connection

The server has default password.

To connect to the web UI use : admin/centreon.

You can also connect to the server using SSH with the account : root/centreon The root password of the DBMS is not initialized.

Note

For security reasons, we highly recommend you to change those passwords after installation.

On the first connection, a message describes the operations to be performed. Run these, especially operations 4 and 5.

Note

To remove this message, remove the /etc/profile.d/centreon.sh file.

Poller

Using Poller VM is nearly the same as central. You just have to exchange SSH keys and configure it on web interface.

Exchange SSH keys

The communication between a central server and a poller server is done by SSH.

You should exchange the SSH keys between the servers.

If you don’t have any private SSH keys on the central server for the centreon user:

# su - centreon
$ ssh-keygen -t rsa

Copy this key on the new server:

# su - centreon
$ ssh-copy-id -i .ssh/id_rsa.pub centreon@IP_POLLER

The password of the centreon user is centreon. It can be easily changed using passwd command.

On Web interface

Configure new poller in Centreon

Since Centreon 18.10, a new wizard is available to define a new poller to a Centreon platform.

Note

It is possible to configure a new Poller manually, however Centreon recommends using the following procedure.

Go to the Configuration > Pollers menu and click Add server with wizard to configure a new poller.

Select Add a Centreon Poller and click Next:

Set the name, the IP address of the poller and the IP address of the Centreon Central server and click Next:

../_images/wizard_add_poller_2.png

Note

The IP address of the poller is the IP address or the FQDN to access to this poller since Centreon Central server.

The IP address of the Centreon Central server is the IP address or the FQDN to access to the Centreon Central server since the poller.

If you want to link this poller to the Centreon Server, click Apply:

../_images/wizard_add_poller_3.png

Else, if you want to link this poller to an existing Remote Server, select the Remote Server in the list. Then click Apply:

Note

If you want to change the sense of the flow between the Centreon Server (or the Remote Server and the Poller, check the Advanced: reverse Centreon Broker communication flow checkbox.

Wait a few seconds, the wizard will configure your new server.

The Poller is now configured:
