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
