Hi all,

W have a single ubuntu 16 machine running elasticsearch (+logstash +kibana) with x-pack enabled, we want to add 2 more machines to this cluster so all will act as masters.

What is the procedure to do this?

I was thinking on something like this:

1. Installing 2 more machines with elasticsearch + x-pack + \<ALL OTHER PLUGINS\>
2. Using same elasticsearch.yml file (and any other configuration file from 1st machine), change on all files the following:

- node.name: \<CURRENT MACHINE\>
- network.host: [\_local\_] to network.host: [\_site\_]
- discovery.zen.minimum\_master\_nodes: 2

1. Re/start elasticsearch on all nodes

p.s.  
This is only for making elasticsearch work on all nodes, logstash and kibana will move later on to their own machines
