Configuring RSA public and private keys for SSH connections in a cluster

Last Updated : Nov 20, 2021 |

About this task

After nodes are added to a cluster, you must configure the RSA public and private keys to enable internode SSH communications.

Use this procedure to configure the RSA public and private keys on the initial node for the entire cluster.

Before you begin

Install all of the required nodes for the cluster.

Procedure

  1. Log in to the Linux shell on the initial Avaya Aura® Web Gateway node as an administrator.
  2. Run the Avaya Aura® Web Gateway configuration utility using the app configure command.
  3. Navigate to Clustering Configuration > Cluster Utilities > Configure SSH RSA Public/Private Keys.

    Avaya Aura® Web Gateway displays the RSA Public and Private key configuration tool.

  4. When the system displays the Add additional hosts to the list? (y/n) prompt, enter y (yes) if you are generating keys for the first time or if you need to generate keys for a new node in the cluster.

    Otherwise, enter n (no).

  5. If you chose to update the node list in the previous step, when Avaya Aura® Web Gateway prompts you, enter the IP address of the non-seed node in the cluster you want to generate keys for and then press Enter.
  6. Repeat the previous step for all remaining non-seed nodes.
  7. When Avaya Aura® Web Gateway prompts you to enter a user name for a node, enter the username for the Linux administrator account that you used to perform the Avaya Aura® Web Gateway installation.
  8. If Avaya Aura® Web Gateway prompts you to replace the existing keys, enter y (yes).
  9. When Avaya Aura® Web Gateway prompts you to enter a password, enter the password for the Linux administrator account that you used to perform the installation.
  10. When the configuration is complete, press Enter.
  11. Return to the main menu.
  12. From the main menu, select Continue and then select Yes to apply the changes.
