Open Distro for Elasticsearch’s security plugin comes with authentication and access control out of the box. To make it easy to get started, the binary distributions contain passwords and SSL certificates that let you try out the plugin. Before adding any of your private data, you need to change the default passwords and certificates. In a prior post, we showed how you can change your admin password in Open Distro for Elasticsearch. In this post we cover changing your SSL certificates.
To change your SSL certificates, you’ll copy the certificate files into the distribution and modify your
elasticsearch.yml to use them. I’ll cover changing certificates for Elasticsearch’s node-to-node communication, REST APIs, and Kibana’s back-end communication to Elasticsearch. I’ll cover both the RPM and Docker distributions of Open Distro for Elasticsearch.
