How to access elastic on IP:9200?

Question

Nginx

Elastic is installed on a VPS and http://localhost:9200responds correctly, but when accessing it via an external IP http://IP-ADDRESS:9200, the error "curl: (7) Failed to connect to ***.***.***.*** port 9200: Connection refused" is returned . How to solve the problem?

Answer 1

Either open the port to the outside, or proxy.

Answer 2

Set connection permission to external ip
Open port in firewall

Answer 3

in /etc/elasticsearch/elasticsearch.yml uncomment the network.host line and change it to "network.host: 0.0.0.0".
twist the elastic.
by itself, publish port 9200 on the router, but first enable xpack and set up authentication if you open port 9200 to everyone.
