I installed Elasticsearch on one machine and my application, developed with Spring Boot, on another machine. When I try to connect, I face a connection refused error. However, when I run the command :
curl http://server_ip:9200
on the application machine, I receive the following response:
{
"name" : "localhost.localdomain",
"cluster_name" : "elasticsearch",
"cluster_uuid" : "_cTpYoMhTUqR9hmt-q93oA",
"version" : {
"number" : "8.9.1",
"build_flavor" : "default",
"build_type" : "tar",
"build_hash" : "a813d015ef1826148d9d389bd1c0d781c6e349f0",
"build_date" : "2023-08-10T05:02:32.517455352Z",
"build_snapshot" : false,
"lucene_version" : "9.7.0",
"minimum_wire_compatibility_version" : "7.17.0",
"minimum_index_compatibility_version" : "7.0.0"
},
"tagline" : "You Know, for Search"
}
Additionally, here are my application.properties :
spring.data.elasticsearch.cluster-name=elasticsearch
spring.data.elasticsearch.cluster-nodes=http://server_ip:9200
spring.data.elasticsearch.repositories.enabled=true
And my elasticsearch.yml :
# Enable security features
xpack.security.enabled: false
xpack.security.enrollment.enabled: false
# Enable encryption for HTTP API client connections, such as Kibana, Logstash, and Agents
xpack.security.http.ssl:
enabled: true
keystore.path: certs/http.p12
# Enable encryption and mutual authentication between cluster nodes
xpack.security.transport.ssl:
enabled: true
verification_mode: certificate
keystore.path: certs/transport.p12
truststore.path: certs/transport.p12
# Create a new cluster with the current node only
# Additional nodes can still join the cluster later
cluster.initial_master_nodes: ["localhost.localdomain"]
# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0
What should I do to solve this problem?
