1. Modify the elasticsearch.yml of the main site and add the following line:
xpack.security.enabled: true
2. Generate a security key
Cut to the ES installation directory and execute bin/elasticsearch-certutil ca -out config/elastic-certificates.p12 -pass ""
will generate elastic in the /home/elasticsearch-7.9.3/config directory -certificates.p12
3. Continue to modify the ES yml file
Add the following four lines:
xpack.security.transport.ssl.enabled: true
xpack.security.transport.ssl.verification_mode: certificate
xpack.security.transport.ssl.keystore.path: elastic-certificates.p12
xpack.security.transport.ssl.truststore.path: elastic-certificates .p12
4. Update the configuration of the cluster node
Copy elastic-certificates.p12 to the config of other nodes, and modify the yml of other nodes at the same time.
5. Restart ES
6. Execute ./elasticsearch-setup-passwords interactive to set the password.
7. Problem handling during the process:
7.1 After executing the third step, execute ./elasticsearch-setup-passwords interactive directly. Always prompts "ERROR: Failed to set password for user [apm_system]"
