I am trying to setup elasticsearch in my Windows system but when I am trying to run it its starting up and showing below reponse when I redirect to http://localhost:9200
.
{
"name" : "DESKTOP-L8UKCFI",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "z8IfZcFaQfSti3P4jhZxbg",
"version" : {
"number" : "8.1.0",

"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
But in console its showing something like this

> # ======================== 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:
https://www.elastic.co/guide/en/elasticsearch/reference/index.html
---------------------------------- Cluster -----------------------------------
Use a descriptive name for your cluster:
#cluster.name: my-application
------------------------------------ Node ------------------------------------
Use a descriptive name for the node:
#node.name: node-1
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: /path/to/data
Path to log files:
#path.logs: /path/to/logs
----------------------------------- Memory -----------------------------------
Lock the memory on startup:
#bootstrap.memory_lock: true
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: 192.168.0.1
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: ["host1", "host2"]
Bootstrap the cluster using an initial set of master-eligible nodes:
#cluster.initial_master_nodes: ["node-1", "node-2"]
For more information, consult the discovery and cluster formation module documentation.
---------------------------------- 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 16-03-2022 06:55:18
--------------------------------------------------------------------------------
Enable security features
xpack.security.enabled: false
xpack.security.enrollment.enabled: false
Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl: enabled: false keystore.path: certs/http.p12
Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl: enabled: false 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: ["DESKTOP-L8UKCFI"]
Allow HTTP API connections from localhost and local networks
Connections are encrypted and require user authentication
http.host: [local, site]
Allow other nodes to join the cluster from localhost and local networks
Connections are encrypted and mutually authenticated
#transport.host: [local, site]
#----------------------- END SECURITY AUTO CONFIGURATION -------------------------
What does it mean someone let me know.
CodePudding user response:
As of ES 8, SSL/TLS is ON by default for HTTP clients.
The WARN message says
http client did not trust this server's certificate
... which means that you need to tell your browser to trust the server certificate. it is self-signed by default, so that's probably the reason.
Or you can simply disable SSL in your elasticsearch.yml
configuration, that would also work.
