• Configure and manage the indexer cluster with the CLI. This topic explains the basics of cluster configuration with the CLI. It provides details on issues that are common to all indexer cluster node types.

The following example shows the basic settings that you typically configure when enabling a peer node. The configuration attributes correspond to fields on the Enable clustering page of Splunk Web.

To enable an instance as a peer node, set mode to "peer". You also need to specify manager_uri, which specifies the cluster's manager node, and replication_port. In addition, you must specify the cluster-wide security key (secret):

splunk edit cluster-config -mode peer -manager_uri https://10.160.31.200:8089 -replication_port 9887 -secret your_key

splunk restart

You can also use the CLI to edit the configuration later. Use the splunk edit cluster-config command, the same command that you use to enable the peer initially.

Refer to the CLI clustering help, along with the server.conf specification file, for the list of configurable settings.
