Hi Guys,

I am trying to start the ElasticSearch server in my Linux system. But it is showing me the below error.

Hi@akhtar,

You need to set the hostname in the elasticsearch.yml file. You can use the below-given code in your elasticsearch.yml file.

cluster.name: elasticsearch
node.name: node1
path.conf: "/etc/elasticsearch"
path.data: "/vol/data/elasticsearch"
path.logs: "/vol/log/elasticsearch"
network.host: 0.0.0.0
http.port: 9200

I hope this will help.
