Hi, I am trying to run multiple nodes with different instances in same machine for load balancing in elasticsearch. I have downloaded three elasticsearch files in the same machine and configured their elasticsearch.yml file with different settings. Please see below: 1. Elasticsearch - default configuration 2. Elasticsearch-node1 [cluster.name](http://cluster.name): Animals [node.name](http://node.name): Snake node.master: true node.data: true transport.tcp.port: 9300 http.port: 9200 discovery.zen.ping.unicast.hosts: ["Snake", "Baboon"] 3. Elasticsearch-node2 [cluster.name](http://cluster.name): Animals [node.name](http://node.name): Baboon node.master: false node.data: true transport.tcp.port: 9301 http.port: 9201 discovery.zen.ping.unicast.hosts: ["Snake", "Baboon"] Please share your opinion and ideas on this. Thank you. ---

You don't really need three different binaries (at least on Linux). You can start separate processes with different config files and data paths... I would leave all as `node.master: true`. You are also using both for `discovery.zen.ping.unicast.hosts:` Default is ports `9200/9300` so node1 (your second node) can't use those, bump them up with one for second and third node. I'm running 5 nodes on same machine on 6 machines in total over two clusters. Definitely can be done 🙂 ---

Hi, Thanks for the response. I am able to create multiple instances with the nodes. Please find my elasticsearch.yml config below. - Elasticsearch - default configuration - Elasticsearch-node1 [cluster.name](http://cluster.name): Animals [node.name](http://node.name): Snake node.master: true node.data: true path.data: "C:\elasticsearch-5.4.2-node1\elasticsearch-5.4.2\data" path.logs: "C:\elasticsearch-5.4.2-node1\elasticsearch-5.4.2\logs" http.port: 9201 discovery.zen.ping.unicast.hosts: ["127.0.0.1"] - Elasticsearch-node2 [cluster.name](http://cluster.name): Animals [node.name](http://node.name): Baboon node.master: false node.data: true path.data: "C:\elasticsearch-5.4.2-node2\elasticsearch-5.4.2\data" path.logs: "C:\elasticsearch-5.4.2-node2\elasticsearch-5.4.2\logs" http.port: 9202 discovery.zen.ping.unicast.hosts: ["127.0.0.1"] ## FYI, the status is red in the cluster health. And I am using logstash to load the csv file into elasticsearch for which I have used the below config. But I am not able to see the other instances(9201 and 9202) loading the data. output { elasticsearch { hosts =\> ["localhost:9200", "localhost:9201", "localhost:9202"] index =\> "cmss" document\_type =\> "cms" document\_id =\> "%{id}" } } Thank you. ---
