Regarding to the curator installed on ES cluster

[Ximeng_Zhao]

Hello All,

I have installed ES 5.2.0 on one Master and two Data nodes. And I also have a Kibana node. I'm wondering to know if I want to install curator, do I need to install it on all nodes that I mentioned above all, or only elastic search Master node? Any explanation will be highly welcomed, thanks for your answer.

Curator only requires network access to Elasticsearch to function. It does not need to be installed on an Elasticsearch node at all.

Thanks, and as here below, what I'm supposed to change in config.yml is just hosts part, right? for instance, change to ES master node IP address with port number 9200. Thank you.
