Starting and stopping DataStax Enterprise 

You can start and stop DataStax Enterprise as a service or stand-alone process.

After you install and configure DataStax Enterprise on one or more nodes, start your cluster beginning with the seed nodes. In a mixed-workload DataStax Enterprise cluster, you must start the analytics seed node first.

Packaged installations include start-up and stop scripts for running DataStax Enterprise as a service. Binary packages do not.
