- Click luci page. The screen appears.from the menu on the left side of the
- Click. The screen appears.
- Enter the node host name for any of the nodes in the existing cluster. After you have entered the node name, the node name is reused as the ricci host name; you can override this if you are communicating with ricci on an address that is different from the address to which the cluster node name resolves.As of Red Hat Enterprise Linux 6.9, after you have entered the node name and ricci host name, the fingerprint of the certificate of the ricci host is displayed for confirmation. If it is legitimate, enter the ricci password
ImportantIt is strongly advised that you verify the certificate fingerprint of the ricci server you are going to authenticate against. Providing an unverified entity on the network with the ricci password may constitute a confidentiality breach, and communication with an unverified entity may cause an integrity breach.Since each node in the cluster contains all of the configuration information for the cluster, this should provide enough information to add the cluster to the luci interface.
- Click. The screen then displays the cluster name and the remaining nodes in the cluster.
- Enter the individual ricci passwords for each node in the cluster, or enter one password and select .
- Click. The previously-configured cluster now displays on the screen.
