Hi,

I have 4 nodes:  
host1,host2,host3 = master,data,ingest (all true)  
host4 = data,ingest (all true)

- enable auth (local)

1. start elasticsearch on all nodes  
do i need to run "bin/elasticsearch-setup-passwords interactive" on each node? or say only at host1

- load balance

1. should i point logstash this way?  
hosts =\> ["host4:9200", "host3:9200", "host2:9200", "host1:9200"]  
or  
it doesn't matter of host order as Logstash will load balance among them.

I'd appreciate any tips/help.

thanks!  
Sirjune

well for auth in a cluster, i found this ([https://www.elastic.co/guide/en/elasticsearch/reference/7.4/configuring-tls.html#node-certificates](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/configuring-tls.html#node-certificates)). Somehow my mind was following single-node steps.

in summary:

1. created CA cert
2. created cert & private key
3. enabled xpack and transport.ssl configs in elasticsearch.yml
4. started elasticsearch on all nodes
5. ran bin/elasticsearch-setup-passwords interactive on 1 node only
6. created roles & users for logstash & filebeat
7. added credentials in the config files of filebeat & logstash, then restart

elasticsearch is receiving the data
