Configure the manager node with the CLI

Read this first

Before reading this topic, see:

Enable the manager node

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

splunk edit cluster-config -mode manager -replication_factor 4 -search_factor 3 -secret your_key -cluster_label cluster1

splunk restart

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

When the manager node starts up for the first time, it will block indexing on the peers until you enable and restart the full replication factor number of peers. Do not restart the manager while it is waiting for the peers to join the cluster. If you do, you will need to restart the peers a second time.

Edit the manager node settings

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

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

Warning: Do not increase the replication factor or search factor on the manager node

Although it is possible to change the settings for the replication factor and search factor, it is inadvisable to increase either of them after your cluster contains significant amounts of data. Doing so will kick off a great deal of bucket activity, which will have an adverse effect on the cluster's performance while bucket copies are being created or made searchable.
