Manually creating a cluster topology

Manually create the cluster topology model when nodes do not have similar SSH credentials required for an automatic import of the cluster topology.

Manually create the cluster topology model that reflects an existing cluster when nodes do not have similar SSH credentials required for an automatic import of the cluster topology.

Procedure

  1. Add SSH credentials so LCM can remotely log in to target machines when performing installation and configuration activities.
  2. Add a configuration profile that defines the required DSE configuration on the development, test, and production clusters for your organization. If the configuration of a cluster is intentionally heterogeneous and not uniform at all levels, you can create multiple configuration profiles to apply individually at the cluster, datacenter, or node levels.
  3. Add a repository so LCM can download the DSE software onto target machines from either the public DataStax repo or an internal install repo mirror set up by your organization.
  4. Define the topology of the cluster:
    1. Add a cluster.
    2. Add its datacenters.
    3. Add its nodes.
  5. Run an installation job of DataStax Enterprise at the cluster level. Lifecycle Manager installs and configures DataStax Enterprise on all datacenters and nodes within the cluster. With Lifecycle Manager, there is deep transparency into the progress of each installation and configuration job available when viewing job summary and details.
