Documentation

Please refer to the technical documentation for detailed information on installing and configuring opendistro-elasticsearch-security plugin.

Quick Start

• Install Elasticsearch

• Install the opendistro-elasticsearch-security plugin for your Elasticsearch version 6.5.4, e.g.:

<ES directory>/bin/elasticsearch-plugin install \
  -b com.amazon.opendistroforelasticsearch:opendistro_security:0.8.0.0

• cd into <ES directory>/plugins/opendistro_security/tools

• Execute ./install_demo_configuration.sh, chmod the script first if necessary. This will generate all required TLS certificates and add the Security Plugin Configuration to your elasticsearch.yml file.

• Start Elasticsearch

• Test the installation by visiting https://localhost:9200. When prompted, use admin/admin as username and password. This user has full access to the cluster.

• Display information about the currently logged in user by visiting https://localhost:9200/_opendistro/_security/authinfo.

Config hot reloading

The Security Plugin Configuration is stored in a dedicated index in Elasticsearch itself. Changes to the configuration are pushed to this index via the command line tool. This will trigger a reload of the configuration on all nodes automatically. This has several advantages over configuration via elasticsearch.yml:

• Configuration is stored in a central place
• No configuration files on the nodes necessary
• Configuration changes do not require a restart
• Configuration changes take effect immediately
