Configuring Elasticsearch for TLS
Step 1: Update Elasticsearch Configuration
Open the elasticsearch.yml configuration file on each node and add the following settings:
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
Configuring TLS in Elasticsearch
Transport Layer Security (TLS) is an essential feature for securing communication in Elasticsearch. By encrypting data in transit, TLS helps protect sensitive information from interception and tampering. This article will guide you through configuring TLS in Elasticsearch, complete with examples and outputs, presented in an easy-to-understand and beginner-friendly manner.
