Create a cluster between elasticsearch nodes

Elastic Stack Elasticsearch
1

Hi,

Need your help!!. I got some issue when creating the elasticsearch 7.x cluster.

Right now I already created and have 3 elasticsearch nodes.
But the issue when I verify my cluster state, it is show the number of nodes is only 1.

When I curl from 192.168.100.143

curl -XGET 'localhost:9200/_cluster/health?pretty'
{
  "cluster_name" : "elastic_cluster",
  "status" : "yellow",
  "timed_out" : false,
  "number_of_nodes" : 1,
  "number_of_data_nodes" : 1,
  "active_primary_shards" : 16,
  "active_shards" : 16,
  "relocating_shards" : 0,
  "initializing_shards" : 0,
  "unassigned_shards" : 5,
  "delayed_unassigned_shards" : 0,
  "number_of_pending_tasks" : 0,
  "number_of_in_flight_fetch" : 0,
  "task_max_waiting_in_queue_millis" : 0,
  "active_shards_percent_as_number" : 76.19047619047619
}

As you can see a the result, it only show for only one node. It should be 3 nodes at the "number of nodes"

My config in elasticsearch.yml for every 3 nodes:

Node 1 (192.168.100.143)

node.master: true
node.data: true
cluster.name: elastic_cluster
cluster.initial_master_nodes: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
node.name: es-1
network.host: [127.0.0.1, 192.168.100.143]
discovery.seed_hosts: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
discovery.zen.minimum_master_nodes: 2

Node 2 (192.168.100.144)

node.master: true
node.data: true
cluster.name: elastic_cluster
cluster.initial_master_nodes: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
node.name: es-2
network.host: [127.0.0.1, 192.168.100.144]
discovery.seed_hosts: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
discovery.zen.minimum_master_nodes: 2

Node 3 (192.168.100.78)

node.master: true
node.data: true
cluster.name: elastic_cluster
cluster.initial_master_nodes: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
node.name: es-3
network.host: [127.0.0.1, 192.168.100.78]
discovery.seed_hosts: ["192.168.100.143", "192.168.100.144", "192.168.100.78"]
discovery.zen.minimum_master_nodes: 2

Thanks

Hi @mario_kazela

What version?

You need to provide the logs from one of the other 2 nodes that does not join the cluster. Look for errors

Did the nodes ever join?

If so you need to take out the following as it is only use 1 time to form the cluster.

cluster.initial_master_nodes:
