Default DSE Multi-Instance configuration files
With DSE Multi-Instance, multiple DataStax Enterprise nodes reside on a single host machine.
To segregate the configuration for each DataStax Enterprise node, node-specific directory structures are used to store configuration and operational files.
For example, in addition to /etc/dse/dse.yaml
, the DSE Multi-Instance dse.yaml
files are stored in /etc/dse-nodeId/dse.yaml
locations.
The server_id
option is generated in DSE Multi-Instance /etc/dse-nodeId/dse.yaml
files to uniquely identify the physical server on which multiple instances are running and is unique for each database instance.
See DSE Multi-Instance server_id
.
