Hi Im just start in ES about some days I have 3 machine in network ips: machine 1 : 10.255.255.6 ,machine 2 : 10.255.255.7, machine 3: 10.255.255.8 i want to setup a es cluster with machine 1 is a master node and two other are slave node. I've installed ES 7.4 in 3 machine and started but when i check by \_cluster/state?pretty i cant see all node in cluster i find some topic with same problem but i can's resolve it anybody can give me a solution to fix ? ![49](https://us1.discourse-cdn.com/elastic/original/3X/c/4/c42b831b24f6a93ac18bd2b07f64a407c6128796.png) thank you ---

@JustinLe you will have to configure discovery for those nodes to start communicating with each other. See [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html) for detailed documentation on how to set things up. ---

Thank you, Armin I've configed ther configuration file but it does not work this is my configuration machine 1: > cluster.name: myCluster > node.name: node-0 > node.master: true > node.data: true > network.host: 10.255.255.6 > http.port: 9200 > cluster.initial\_master\_nodes: ["node-0", "node-1", "node-2", "node-3"] > discovery.seed\_hosts: ["10.255.255.6", "10.255.255.7", "10.255.255.8", "10.255.255.9"] machine 2: > cluster.name: myCluster > node.name: node-1 > node.master: true > node.data: true > network.host: 10.255.255.7 > http.port: 9200 > cluster.initial\_master\_nodes: ["node-0", "node-1", "node-2", "node-3"] > discovery.seed\_hosts: ["10.255.255.6", "10.255.255.7", "10.255.255.8", "10.255.255.9"] machine 3: > cluster.name: myCluster > node.name: node-2 > node.master: true > node.data: true > network.host: 10.255.255.8 > http.port: 9200 > cluster.initial\_master\_nodes: ["node-0", "node-1", "node-2", "node-3"] > discovery.seed\_hosts: ["10.255.255.6", "10.255.255.7", "10.255.255.8", "10.255.255.9"] machine 4: > cluster.name: myCluster > node.name: node-3 > node.master: true > node.data: true > network.host: 10.255.255.9 > http.port: 9200 > cluster.initial\_master\_nodes: ["node-0", "node-1", "node-2", "node-3"] > discovery.seed\_hosts: ["10.255.255.6", "10.255.255.7", "10.255.255.8", "10.255.255.9"] please help me find out the wrong config ---

try this shutdown all, setup this two line on config of all node cluster.initial\_master\_nodes: ["node-0"] discovery.seed\_hosts:["node-0", "node-1", "node-2", "node-3"] now start. if this does not work you might have to remove your path.data dir default is /var/data/elasticsearch/\* ---

What do the logs say after this change? There should be some intelligible warnings about the discovery/master-election process in there now. Also, did you ensure that the nodes can see each other network-wise (i.e. ping each other and the relevant network port (9300) is open? ---

the logs dont say anything the instances was started well but nodes do not see each other i using ```auto telnet ip 9300 ``` and it connected i've change to one master and 3 data node. and it still does not work ---

@JustinLe sorry I missed one thing here: See this documentation: [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-discovery-bootstrap-cluster.html#modules-discovery-bootstrap-cluster-joining) Since you already started all the nodes once without the proper configuration they formed individual "clusters". You'll have to follow the steps in that link to merge them into a single cluster now. ---
