# ======================== OpenSearch Configuration =========================
#
# NOTE: OpenSearch 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.opensearch.org
#
# ---------------------------------- Cluster -----------------------------------
#
# Use a descriptive name for your cluster:
#
#cluster.name: opensearch cluster1
#
# ------------------------------------ Node ------------------------------------
#
# Use a descriptive name for the node:
#
#node.name: node-1
#
# Add custom attributes to the node:
#node.max_local_storage_nodes
#node.attr.rack: r1
#
# ----------------------------------- Paths ------------------------------------
#
# Path to directory where to store the data (separate multiple locations by comma):
#
#path.data: /opt/opensearch-2.12.0/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.
#
# OpenSearch performs poorly when the system is swapping the memory.
#
# ---------------------------------- Network -----------------------------------
#
# Set the bind address to a specific IP (IPv4 or IPv6):
#
#network.host: localhost
network.host: 0.0.0.0
# Set a custom port for HTTP:
#network.host: 172.31.4.236
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 cluster-manager-eligible nodes:
discovery.type: single-node
#cluster.initial_cluster_manager_nodes: ["node-1", "node-2"]
#
# For more information, consult the discovery and cluster formation module documentation.
#
# ---------------------------------- Gateway -----------------------------------
#
# Block initial recovery after a full cluster restart until N nodes are started:
#
#gateway.recover_after_nodes: 3
#
# For more information, consult the gateway module documentation.
#
# ---------------------------------- Various -----------------------------------
#
# Require explicit names when deleting indices:
#
#action.destructive_requires_name: true
#
# ---------------------------------- Remote Store -----------------------------------
# Controls whether cluster imposes index creation only with remote store enabled
# cluster.remote_store.enabled: true
#
# Repository to use for segment upload while enforcing remote store for an index
# node.attr.remote_store.segment.repository: my-repo-1
#
# Repository to use for translog upload while enforcing remote store for an index
# node.attr.remote_store.translog.repository: my-repo-1

#
#opensearch.experimental.feature.segment_replication_experimental.enabled: false

# ahead of time.

Please try to execute the following command:

You need to remove this parameter.

-bash-4.2# curl -k -u admin:admin -XGET https://localhost:9200
curl: (7) Failed to connect to localhost port 9200 after 0 ms: Couldn’t connect to server
-bash-4.2#

yes I removed, pls help me to resolve this issue

Hi @rathiga ,

Do you have any errors in the OpenSearch logs?

Please try executing the following commands:

openssl s_client -connect localhost:9200
curl -k -u username:password -XGET https://your-hostname:9200

where i want execute the commands
