Modifying how OpsCenter connects to clusters

Cluster Connection settings define how OpsCenter connects to your cluster. For example, if you’ve enabled authentication or encryption on your cluster, you’ll need to specify that information here.

Procedure

  1. Click Settings on the top right of the UI, then click Cluster Connections.
  2. Select the cluster you want to edit from the Cluster drop-down.
  3. Change the IP addresses of cluster nodes.
  4. Change JMX and Thrift listen port numbers.
  5. Edit the user credentials if the JMX or Thrift ports require authentication.
  6. (Optional) You can check the DSE security (kerberos) is enabled on my cluster and enter the service name.
  7. (Optional) You can check the Client node encryption is enabled on the cluster and enter your PEM encoded certificate in CA Certificate File Path.
    If you have a CER encoded certificate, use the following command to convert it.
    $ openssl x509 -inform der -in certificate.cer -out certificate.pem
  8. (Optional) If client node encryption is enabled, you can check the Validate SSL Certificates and enter the Truststore File Path and Trustore Password.
    For more information about enabling Kerberos see Security in the DSE Documentation.
  9. Click Save Cluster.
