Hi, Recently setup elastic on a windows host but performance is being hampered as it`s only a single node. I have setup a second node but cannot get it to see the cluster. both elasticsearch.yml config`s below: Node 1: bootstrap.memory\_lock: false cluster.name: elasticsearch http.port: 9200 node.data: true node.ingest: true node.master: true node.max\_local\_storage\_nodes: 1 node.name: ELASTIC-NODE1 path.data: D:\6.2.3\data path.logs: D:\6.2.3\logs transport.tcp.port: 9300 thread\_pool.search.queue\_size: 10000 xpack.license.self\_generated.type: basic Node 2: bootstrap.memory\_lock: false cluster.name: elasticsearch http.port: 9200 node.data: true node.ingest: true node.master: true node.max\_local\_storage\_nodes: 1 node.name: ELASTIC-NODE2 path.data: C:\elasticsearch-6.2.3\data path.logs: C:\elasticsearch-6.2.3\logs transport.tcp.port: 9300 thread\_pool.search.queue\_size: 10000 When viewing the nodes in elasticsearchHQ i can only see one node in the cluster... Any help would be great. Cheers, ---

You can't have two nodes run on the same TCP ports. Change `Node 2` to 9201/9301. ---

they are separate machines, does that still need to be run on different ports? ---

Oh. The they can use the same port 🙂 But > By default, Elasticsearch binds to loopback addresses only — e.g. 127.0.0.1 and [::1]. This is sufficient to run a single development node on a server. > **[network.host | Elasticsearch Reference \[6.2\] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/network.host.html)** You need to set `network.host`. ---

Added this to both hosts (alternate settings on each), restarted services, still showing 1 node ☹ network.host: x.x.x.x discovery.zen.ping.unicast.hosts: - 192.168.51.88:9300 - 192.168.51.89:9300 ---

Are the individual nodes working ok? What do you see if you go to - [http://192.168.51.88:9200](http://192.168.51.88:9200) - [http://192.168.51.89:9200](http://192.168.51.89:9200) And where do you see just one node? ---

Looks good... Last thing I would test is making the node names small caps. Also, can connect with `telnet` from one machine to the other on port 9200 and 9300? ---

after applying those values, i cannot connect via elasticsearchhq or kibana, kibana is now prompting for credentials but i havent set any? ---

You have installed x-pack or maybe the new version of ES comes with x-pack included. [https://www.elastic.co/guide/en/x-pack/6.2/setting-up-authentication.html#bootstrap-elastic-passwords](https://www.elastic.co/guide/en/x-pack/6.2/setting-up-authentication.html#bootstrap-elastic-passwords) Or, you have to set `xpack.license.self_generated.type: basic` on both nodes. I haven't played too much with ES v6 yet... ---

Yep, i had to re-install just to get shot of the x-pack, set the configs on both to the below and all is working 🙂 bootstrap.memory\_lock: false cluster.name: elasticsearch http.port: 9200 node.data: true node.ingest: true node.master: true node.max\_local\_storage\_nodes: 1 node.name: ELASTIC-NODE1 path.data: D:\6.2.3\data path.logs: D:\6.2.3\logs transport.tcp.port: 9300 thread\_pool.search.queue\_size: 10000 network.host: x.x.x.x discovery.zen.ping.unicast.hosts: - x.x.x.1:9300 - x.x.x.2:9300 thanks for your help A\_B!
