      Attention: Installing the DSE demos is not recommended for production. Only install the demos in development environments to run tutorials.

    DataStax Enterprise is ready for additional configuration.

  5. Optional: Single-node cluster installations only:
    1. If DataStax Enterprise is not already running:
      sudo service dse start
      Note: For other start options, see Starting DataStax Enterprise as a service.
    2. Verify that DataStax Enterprise is running:
