Default file locations for package and Installer-Services installations

The default location of the files depends on how DataStax Enterprise is installed:

  • The files are in the same locations for Package installations and when the Services is selected using the DataStax Installer.

  • The files are in the same locations for Tarball and when No Services is selected using the DataStax Installer.

[Deprecated in DSE 6.8] 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.

Directories Description

/etc/dse

/etc/dse/dse.yaml is the primary configuration file for DataStax Enterprise

/etc/dse-node1

/etc/dse-node1/dse.yaml is the configuration file for the DataStax Enterprise node in the dse-node1 directory

/etc/dse-node2

/etc/dse-node2/dse.yaml is the configuration file for the DataStax Enterprise node in the dse-node2 directory

For a comprehensive list of file locations in a DSE Multi-Instance cluster, see directories for DSE Multi-Instance.
