Hi Team,
I have a fedora distribution environment setup where I have 1 master node and 2 data node for elastic search and single kibana and logstash in total I've 4 servers where logstash and kibana are in a single server.
I'm aware of single node security with Xpack enabled however I'm confused in a HA cluster where I've master and data nodes.
My question is if I enable X-Pack in my master node by adding
xpack.security.enabled: true
in my elasticsearch.yml file and create passwords for my elastic search application by
bin/elasticsearch-setup-passwords interactive
then how my data nodes are going to discover my master node as my master node is set up with authentication, what changes or authentication I need to add in my data nodes configuration so that they can authenticate each other.
and also if I add my master nodes server IP in kibana.yml then it will authenticate the master node as i give username and password for my master node elasticsearch over there.
This is the main authentication between elasticsearch, i understand i need to enable X-pack in each ES node but i don't get how my ES nodes will authenticate each other.
and how it will reflect in my Kibana. as in my data node, master node is not discoverable so kibana instance is not starting in my browser but it's service is UP and Runnnig.
Will be a great help if anyone could clear my concepts
Thanks and Regards,
