Step 1: Edit file /etc/elasticsearch/elasticsearch.yml

vi /etc/elasticsearch/elasticsearch.yml

Uncomment line:

#network.host: 192.168.0.1

Change 192.168.0.1 to 0.0.0.0 (or your server ipaddress)

Step 2:

service elasticsearch restart

Step 3: open port with iptables

iptables -A INPUT -p tcp -m tcp --dport 9200 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 9300 -j ACCEPT
service iptables save
