Preparing for installation
Before installing Ranger, you need to make sure that the cluster meets the following requirements:
-
An ADS cluster of version 1.6.2 or higher is installed and configured.
-
The ADS cluster is enabled and configured for SASL_PLAINTEXT with PLAIN, Kerberos, or LDAP authentication. For more help, follow the guides:
-
When using an external DBMS to store metadata, a MySQL database instance used by Ranger should be started and available. The Ranger installer will create two new users (default names:
rangeradmin
andrangerlogger
) and two new databases (default names:ranger
andranger_audit
). -
Before configuring authorization for all users, a principal must be created in the MIT Kerberos database or an account in the MS Active Directory database.
