I have setup 3 node cluster in elasticsearch. but it display only single node in the cluster.
I have specify:
Cluster.name
node.node
network.host
discovery.seed_hosts:
when i do the " curl -XGET https://localhost:9200/_cat/nodes?v -u admin:admin --insecure"
display only single node instead of 3.
can anyone confirm what wrong here.
Hello @sourabhsharma, can you please provide the data from your config, like bellow one:
cluster.name: test-cluster
node.name: test
network.host: ["_local_", "_site_"]
http.host: ["_local_", "_site_"]
http.port: 9200
transport.host: ["_local_", "_site_"]
transport.port: 9300
path.data: /opt/elk-data
path.logs: /var/log/elasticsearch
cluster.initial_master_nodes: ["test"]
discovery.seed_hosts: ["192.168.1.10:9300"]
cluster.name: odfe-cluster
node.name: odfe-d2
#node.master: true
#node.data: true
#node.ingest: true
path.data: /var/lib/elasticsearch
path.logs: /var/log/elasticsearch
network.host: “0.0.0.0”
#discovery.seed_hosts: [“xxx”, “xxx”]
#discovery.seed_hosts: [“x.x.x.x”,“x.x.x.x” ]
discovery.zen.ping.unicast.hosts: [“xxxx”,“xxxx”]
#discovery.zen.minimum_master_nodes: 1

smilarly I have define the configuration into two other nodes.
root@data3:/home/ubuntu# curl -XGET https://localhost:9200/_cat/nodes?v -u admin:admin --insecure
ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
x.x.x.x 26 97 1 0.06 0.03 0.02 dimr * odfe-d2
root@data3:/home/ubuntu#
ideally it should return 3 nodes in cluser.

@sourabhsharma, can you please check and post here 3 configuration keys from each host:
host 1
node.name: odfe-d1
cluster.initial_master_nodes: ["odfe-d1", "odfe-d2", "odfe-d3"]
discovery.seed_hosts: ["192.168.1.11:9300", "192.168.1.12:9300", "192.168.1.13:9300"]
host 2
node.name: odfe-d2
cluster.initial_master_nodes: ["odfe-d1", "odfe-d2", "odfe-d3"]
discovery.seed_hosts: ["192.168.1.11:9300", "192.168.1.12:9300", "192.168.1.13:9300"]
host 3
node.name: odfe-d3
cluster.initial_master_nodes: ["odfe-d1", "odfe-d2", "odfe-d3"]

do I need create any certificate and that i need to use in my cluster ?

Can you send me any blog link that i can follow and setup on my vm.
@sourabhsharma, please add keys to your config as in my example above:
node.name: odfe-master/odfe-d1/odfe-d2
cluster.initial_master_nodes: ["odfe-master", "odfe-d1", "odfe-d2"]
discovery.seed_hosts: ["172.31.12.233","172.31.5.28","172.31.11.196" ]
All 3 keys should be placed on every node and Elasticsearch service should be restarted.
For more information, please refer to the documentation: Important discovery and cluster formation settings
I have already add these 3 keys on every node. but these 3 nodes not comes on cluster. r you available for quick zoom call.
@sourabhsharma, yes - let’s try. Don’t have so much experience with zoom - jus created an account. I’m in +3 time zone.
my skype id : saurabh.find1, can you please ping me
Hi @sourabhsharma & @stmx38,
could you find a solution?
I have similar problems …
@feldversuch, as I remember the issue was related to the Debian specific installation. On CentOS via RMP all worked fine.
@stmx38 , thanks for the feedback.
I was able to start my cluster successfully - but only with security disabled.
