OpsCenter 4.0 User Guide

Creating a cluster

To provision a cluster using OpsCenter.

When deploying to EC2, the OpsCenter daemon-to-agent communication must be open to 0.0.0.0 in the EC2 security group (that is for ports 61620 and 61621).

Procedure

  1. Click Create Cluster. The Create Cluster dialog displays.
  2. (Optional) Choose whether to provision a cluster in the cloud or to a local machine by selecting the Cloud or Local. The Cloud and Local buttons only appear if OpsCenter is running in the cloud.
  3. Fill out the form as appropriate.
    • If you select Local the Local pane displays. The DataStax credentials are the ones which were emailed to you, when you signed up, while the node credentials are the user id on each node with sudo privileges.

    • If you select Cloud the Cloud pane displays. (OpsCenter currently only supports the AWS EC2 cloud.)

    Fill out the form as appropriate.
