Configuring Elasticsearch for SSL/TLS
Step 1: Update Elasticsearch Configuration
Open the elasticsearch.yml configuration file on each node and add the following settings to enable SSL/TLS:
xpack.security.enabled: true
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: /path/to/elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: /path/to/elastic-certificates.p12
xpack.security.http.ssl.enabled: true
xpack.security.http.ssl.keystore.path: /path/to/elastic-certificates.p12
xpack.security.http.ssl.truststore.path: /path/to/elastic-certificates.p12
Replace /path/to/elastic-certificates.p12 with the actual path to your certificate file.
Step 2: Restart Elasticsearch
Restart each Elasticsearch node to apply the new configuration:
bin/elasticsearch
