Hi All ,
i have a working ELK stack with Filebeat and kafka .
I want to secure it with X-pack .
I have gone through the documents but i am facing issue while implementing it .
Can someone help on this ?
i can share details if required .
If you have a commercial subscription with us, then your support engineer can help.
Otherwise, we're able to support you here, but you will need to provide much more information.
- What version are you running?
- What steps have you taken?
- What issue did you run into?
- What have you tried so far?

I dont have commercial subsciption , i am testing with trial version .
Below are the details ,
-
i am testing with 6.1.1 versions of Elastic search and X-pack .
-
I have installed x-pack on all 3 nodes of elastic search cluster . also generated node certificate for all 3 nodes .
-
Update elasticsearch.yml with below ,
###################################################### X-Pack ###############################################
action.auto_create_index: .security,.monitoring*,.watches,.triggered_watches,.watcher-history*,.ml,*
xpack.ssl.key: /etc/elasticsearch/certs/node01/node01.key
xpack.ssl.certificate: /etc/elasticsearch/certs/node01/node01.crt
xpack.ssl.certificate_authorities: /etc/elasticsearch/certs/node01/node01.crt
xpack.security.transport.ssl.enabled: true
xpack.security.http.ssl.enabled: true
on all 3 nodes .
I have generated certificates on 1 node for all 3 nodes with certgen cmd .
- Now after generating certificates and copying them to each node and updating yml . when i am restarting elastic cluster , it is throwing below exceptions ,
exceptions are related to certificates ,
