Adding an existing cluster

Add an existing cluster to manage using OpsCenter.

Add an existing cluster to manage within OpsCenter.
Note: If configuration encryption is active, OpsCenter automatically encrypts the sensitive fields such as passwords and writes the encrypted values to the configuration files. Do not enter manually encrypted values in the password fields.

If commitlog archiving is enabled on a cluster, OpsCenter automatically enables commitlog archiving on the new nodes when adding new nodes to a cluster using OpsCenter. If you manually add nodes to a cluster and commitlog archiving is enabled, you must manually copy commitlog_archiving.properties to the new nodes prior to starting DataStax Enterprise.

Procedure

  1. Click New Cluster.
    The New Cluster prompt appears.

  2. Click Manage Existing Cluster.
    The Add Cluster dialog appears.



  3. Enter at least one hostname or IP address for a node in the cluster. 
    
ec2-123-45-6-789.us-west-1.compute.amazonaws.com
ec2-234-56-7-890.us-west-1.compute.amazonaws.com
  4. If you are not using the default JMX or Native Transport ports, enter the appropriate port numbers.
  5. If required, click Add Credentials and enter the username and password for JMX or Native Transport ports.
  6. Optional: Select the DSE security (kerberos) is enabled on my cluster check box and enter the service name.
  7. Optional: Select the Client node encryption is enabled on my cluster check box and enter your PEM-encoded certificate in the CA Certificate File Path field.
    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, select Validate SSL Certificates and enter the Keystore File Path and Keystore Password.
    For more information about enabling Kerberos, see Security in the DataStax Enterprise Documentation.
