Hello,
I am setting up one cluster with two nodes to elasticsearch. I am using virtualbox with ubuntu 22.04 image.
I already configurated all nodes with these elasticsearch.yml:
Node1:
root@osboxes:/var/log/elasticsearch# cat /etc/elasticsearch/elasticsearch.yml
======================== Elasticsearch Configuration =========================
NOTE: Elasticsearch comes with reasonable defaults for most settings.
Before you set out to tweak and tune the configuration, make sure you
understand what are you trying to accomplish and the consequences.
The primary way of configuring a node is via this file. This template lists
the most important settings you may want to configure for a production cluster.
Please consult the documentation for further information on configuration options:
Elasticsearch Guide | Elastic
---------------------------------- Cluster -----------------------------------
Use a descriptive name for your cluster:
cluster.name: my-cluster
------------------------------------ Node ------------------------------------
Use a descriptive name for the node:
node.name: node01
Add custom attributes to the node:
#node.attr.rack: r1
----------------------------------- Paths ------------------------------------
Path to directory where to store the data (separate multiple locations by comma):
path.data: /var/lib/elasticsearch
Path to log files:
path.logs: /var/log/elasticsearch
----------------------------------- Memory -----------------------------------
Lock the memory on startup:
bootstrap.memory_lock: false
Make sure that the heap size is set to about half the memory available
on the system and that the owner of the process is allowed to use this
limit.
Elasticsearch performs poorly when the system is swapping the memory.
---------------------------------- Network -----------------------------------
By default Elasticsearch is only accessible on localhost. Set a different
address here to expose this node on the network:
network.host: 192.168.0.24
By default Elasticsearch listens for HTTP traffic on the first free port it
finds starting at 9200. Set a specific HTTP port here:
http.port: 9200
For more information, consult the network module documentation.
--------------------------------- Discovery ----------------------------------
Pass an initial list of hosts to perform discovery when this node is started:
The default list of hosts is ["127.0.0.1", "[::1]"]
discovery.seed_hosts: ["192.168.0.24","192.168.0.25"]
Bootstrap the cluster using an initial set of master-eligible nodes:
cluster.initial_master_nodes: ["node01", "node02"]
For more information, consult the discovery and cluster formation module documentation.
--------------------------------- Readiness ----------------------------------
Enable an unauthenticated TCP readiness endpoint on localhost
#readiness.port: 9399
---------------------------------- Various -----------------------------------
Allow wildcard deletion of indices:
#action.destructive_requires_name: false
#----------------------- BEGIN SECURITY AUTO CONFIGURATION -----------------------
The following settings, TLS certificates, and keys have been automatically
generated to configure Elasticsearch security features on 12-07-2022 20:10:54
--------------------------------------------------------------------------------
Enable security features
xpack.security.enabled: false
xpack.security.enrollment.enabled: true
Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
enabled: true
keystore.path: certs/http.p12
Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
enabled: true
verification_mode: certificate
keystore.path: certs/transport.p12
truststore.path: certs/transport.p12
Create a new cluster with the current node only
Additional nodes can still join the cluster later
#cluster.initial_master_nodes: ["osboxes"]
Allow HTTP API connections from anywhere
Connections are encrypted and require user authentication
http.host: 0.0.0.0
Allow other nodes to join the cluster from anywhere
Connections are encrypted and mutually authenticated
#transport.host: 0.0.0.0

When second node is starting I didn't see any information about /var/log/elasticsearch/my-cluster.log.
Both Elasticsearch each node are up, but each one with the same cluster name but different cluster id:
Node1:
root@osboxes:/var/log/elasticsearch# curl -H "Content-Type: application/json" -XGET 127.0.0.1:9200/_cluster/state/master?pretty
{
"cluster_name" : "my-cluster",
"cluster_uuid" : "AetnBE4HSHWZBxV104hYsQ"
}
Node2:
root@silas-VirtualBox:/var/log/elasticsearch# curl -H "Content-Type: application/json" -XGET 127.0.0.1:9200/_cluster/state/master?pretty
{
"cluster_name" : "my-cluster",
"cluster_uuid" : "7sH6JOYoT-iCgTubuPXgpw"
}
Could anyone help me?
