Configure the search head with the CLI

Before reading this topic, see:

Enable a search head

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

To enable an instance as a search head, set mode to "searchhead". You also need to specify the manager_uri and the cluster-wide security key (secret):

splunk edit cluster-config -mode searchhead -manager_uri https://10.160.31.200:8089 -secret your_key

splunk restart

The -secret flag modifies the pass4SymmKey setting in the [clustering] stanza of server.conf.

Edit the search head settings

You can also use the CLI to edit the configuration later.

Important: When you first enable a search head, you use the splunk edit cluster-config command. To change the search head configuration, you must instead use the splunk edit cluster-manager command.

For example, to change the security key (secret), use this command:

splunk edit cluster-manager https://10.160.31.200:8089  -secret newsecret123

Important: The splunk edit cluster-manager command always takes the current manager node URI:port value as its initial parameter. For example, this command connects the search head to a different manager node by setting a new value for the -manager_uri parameter, but it provides the value for the old manager node as its initial parameter:

splunk edit cluster-manager https://10.160.31.200:8089  -manager_uri https://10.160.31.55:8089

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