my apologies. My instructions were not 100% correct. You are not supposed to start Kibana on server7, but rather stop the instance running on server1 and restart Kibana again with the parameters to connect to the elasticsearch node on server7.
Instructions of step 7:
Next, you are going to see how to use Kibana with security.
Navigate to the terminal window that has Kibana up and running.
Stop Kibana by pressing `ctrl+c` and then
run the following command to start Kibana connecting to `node7`.
Command to execute as of step 7:
./kibana/bin/kibana --elasticsearch.hosts="http://server7:9200" --elasticsearch.username=kibana_system --elasticsearch.password=<pwd> --server.port=5602
(please use the password for the kibana_system user)
I hope that will help. Cheers,
