Chapter 1. Overview

Apache Ranger can be installed either manually using the Hortonworks Data Platform (HDP) or the Ambari 2.0 User Interface. Unlike the manual installation process, which requires you to perform a number of installation steps, installing Ranger using the Ambari UI is much simpler and easier. The Ranger service option will be made available through the Add Service wizard after the HDP cluster is installed using the installation wizard.

	Note
	Start the DataNode using the applicable commands in the "Controlling HDP Services Manually" section of Ambari Installation Guide

Once Ambari has been installed and configured, you then need only use the Add Service wizard to install the following components:

After these components are installed and started, you can enable Ranger plugins by navigating to each individual Ranger service (HDFS, Hive, Knox, and Storm) and modifying the configuration under advanced ranger-service>-plugin-properties.

Note that when you enable a Ranger plugin, you will need to restart the component.

	Note
	Enabling Apache Storm requires you to enable Kerberos. Refer to the Configuring Kerberos Authentication for Storm section of Installing HDP Manually for more information on how to enable Kerberos for Storm.
