Elasticsearch 7.12 cluster 3 node installation

[cuongnp (Phu Cuong Nguyen)]

Hi all,
I tried to setup 3 Elasticsearch nodes with configuration below

• file /etc/hosts (on 3 nodes)
  
  
• elasticsearch.yml
  NODE 1 (master-1)
  cluster.name: es-cluster
  node.name: "master-1"
  node.master: true
  node.data: true
  path.data: /home/elasticsearch/elasticsearch-7.12.0/data
  path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs
  network.host: [ local, site ]
  discovery.seed_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"]
  cluster.initial_master_nodes: ["master-1", "master-2", "master-3"]

NODE 2 (master-2)
cluster.name: es-cluster
node.name: "master-2"
node.master: true
node.data: true
path.data: /home/elasticsearch/elasticsearch-7.12.0/data
path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs
network.host: [ local, site ]
discovery.seed_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"]
cluster.initial_master_nodes: ["master-1", "master-2", "master-3"]

NODE 3 (master-3)
cluster.name: es-cluster
node.name: "master-3"
node.master: true
node.data: true
path.data: /home/elasticsearch/elasticsearch-7.12.0/data
path.logs: /home/elasticsearch/elasticsearch-7.12.0/logs
network.host: [ local, site ]
discovery.seed_hosts: ["172.19.11.74", "172.19.11.75", "172.19.11.76"]
cluster.initial_master_nodes: ["master-1", "master-2", "master-3"]

I expect to get 3 node with both master and data role in a cluster but this is the result when I get information on each node (only 1 node in cluster)

Can you guys have any advice for my configuration ?, tks

The configuration looks ok now, but I think you used a different configuration earlier that has got you stuck. The simplest thing to try is to delete /home/elasticsearch/elasticsearch-7.12.0/data on all the nodes and try again. See these docs for more information.

/home/elasticsearch/elasticsearch-7.12.0/data

Thanks David, It works now
