Hello everyone, I have installed elasticsearch 7.2 on my ubuntu server running on AWS EC2.

I have set the heap memory to minimal level and started the ES service, with default elasticsearch.yml settings the ES is working fine in localhost, i.e., when i pass the command "curl localhost:9200" i am getting the result.

I have to expose this ES service for public reachability, i.e., from internet browser.  
for which I have opened up the port 9200 in AWS EC2 security group to anyone (0.0.0.0/0) and modified the elasticsearch.yml file network.host parameter to 0.0.0.0

once after updating this and restarting the ES service, it is getting failed. i have tried it with Elasticsearch v6.8.1 also.

FYR,

Java Version: openjdk version "11.0.3" 2019-04-16

//# ======================== 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](https://www.elastic.co/guide/en/elasticsearch/reference/index.html)

# 

# ---------------------------------- Cluster -----------------------------------

# 

# Use a descriptive name for your cluster:

# 

cluster.name: orgfarm-cluster

# 

# ------------------------------------ Node ------------------------------------

# 

# Use a descriptive name for the node:

# 

node.name: orgfarm-node

# 

# 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: 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 -----------------------------------

# 

# Set the bind address to a specific IP (IPv4 or IPv6):

# 

network.host: 0.0.0.0

# 

# Set a custom port for HTTP:

# 

http.port: 9200

# 

# For more information, consult the network module documentation.

# 

# --------------------------------- Discovery ----------------------------------

# 

# Pass an initial list of hosts to perform discovery when new node is started:

# The default list of hosts is ["127.0.0.1", "[::1]"]

# 

#discovery.zen.ping.unicast.hosts: ["host1", "host2"]

# 

# Prevent the "split brain" by configuring the majority of nodes (total number of master-eligible nodes / 2 + 1):

# 

#discovery.zen.minimum\_master\_nodes:

# 

# For more information, consult the zen discovery 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  
//
