This depends if you want to do a rolling restart or if you can afford a full cluster restart. In any case, you do not “install” any certificates with sgadmin, they are just configured in elasticsearch.yml. So in case you can do a full cluster restart:

  1. Generate new certificates. You need at least:

  • Root CA

  • One node certificate (although it’s advisable to have separate certificates for each node)

  • One admin certificate

  1. Stop all nodes

  2. Place the root and node certs in the config directory of ES

  3. Change elasticsearch.yml to point to the new certs

  4. Start all nodes

That should be all.
