Deployment Architecture

How to upgrade a single Search Head to a Search Head Cluster?

Hello,

please I would like to know if the best approach to "move" a single Search Head  to a Search Head Cluster is to deploy first a deployer, than a single-member search head cluster (connected to the deployer and elected as captain), with replication factor to 1, and then add other members to the Search Head Cluster.

 

Info here: Deploy a single-member search head cluster - Splunk Documentation

 

Thanks and kind regards.

Ciao Giuseppe,

thanks for helping, but I have to apologize, because my question was not well explained.

I have an environment with only one search head and I would like to move to a cluster environment; there are not other search heads at the moment.

I know that at the end I should have 1 deployer and 3 search heads, but, as told above, for the time being I have only one server: a search head.


Thanks again.

Hi @lucacaldiero,

in this case you have to create you Cluster from zero:

  • install Deployer and the other Search Heads,
  • copy the installed apps (custom or from Splunkbase) from the actual SH to the Deployer (to the $SPLUNK_HOME/etc/shcluster folder),
  • configure the Cluster following the instructions of the previous message ,
  • deploy Apps from Deployer to all the SHs.

Ciao.

Giuseppe
