Elastic search automatically stopped after

[Balaji_Ramachandran (Balaji)]

Hi,

We are trying to enable elasticsearch 7.3 using ubuntu 16.04, but after 30 seconds, the service gets automatically stopped. This issue happens while setting up to a specific bind network address to 0.0.0.0. Here I have shared the current elasticsearch .yml configuration file and status.

We made some changes in the .yml configuration file

# 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
#

and the status

 elasticsearch.service - Elasticsearch
   Loaded: loaded (/usr/lib/systemd/system/elasticsearch.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Mon 2019-08-26 09:39:21 EST; 5min ago

Hello @Balaji_Ramachandran,

In production mode, any bootstrap checks that fail will cause Elasticsearch to refuse to start.

When you change the network.host the elasticsearch node assumes that you are moving from development mode to production mode, you should see in the log a msg that say you shloud configure one of the bootstrap options.
