Hi all, I am new with ELK

I follow the guide on internet to install ELK cluster 8. on redhat 7 by rpm package ( 3 nodes)

But i met this error

[root@elk02 elasticsearch]# /usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token xxxxxxxxxxxxxxxxxxxxxxxx  
Generates all the necessary security configuration for a node in a secured cluster

Option Description

* * *

-E Configure a setting  
--enrollment-token The enrollment token to use  
-h, --help Show help  
-s, --silent Show minimal output  
-v, --verbose Show verbose output

ERROR: Aborting enrolling to cluster. This node doesn't appear to be auto-configured for security. Expected configuration is missing from elasticsearch.yml., with exit code 64

Please help me to resolve this error

Thanks you so much
