I am trying to install a license in Kibana via Management / Elasticsearch / License Management.
It tells me
Error encountered uploading license: Cannot install a [PLATINUM] license unless TLS is configured or security is disabled
Since I have no security currently and I can just hit the cluster, I'd like to disable security on my 3 node cluster.
The following page says that I need to set
xpack.security.enabled: false on all nodes.
Does that mean that I need to locate
elasticsearch.yml file on each node and set the setting to false? And then restart the cluster.
Is there more to it or this is all?
