Adding a server to a cluster

To add a server to a cluster:

  1. In the application web interface window, select Servers.
  2. Click Add server.

    The Add server window opens.

  3. In the IP address and Port text boxes, type the IP address and port of the server that you want to add.
  4. If necessary, in the Comment (optional) box specify additional information about the server.
  5. Click Next.
  6. Compare certificate fingerprints in the Confirm server and in the certificate file in the nginx service directory (/etc/nginx/kwts-control/management.crt for the Master server or Secondary master server and /etc/nginx/kwts-worker/management.crt for the Worker server). If fingerprints match, click Confirm.

    You can get a server certificate fingerprint using the following command:

    • For a Master server or a Secondary master server:

      openssl x509 -noout -fingerprint -sha256 -inform pem -in /etc/nginx/kwts-control/management.crt

    • For the Worker server:

      openssl x509 -noout -fingerprint -sha256 -inform pem -in /etc/nginx/kwts-worker/management.crt

The server will be added to the cluster and will be displayed in the server table on the Servers page.
