Changing the Ranger Data Source to LDAP for a Normal Cluster

By default, the Ranger data source of the security cluster can be accessed by FusionInsight Manager LDAP users. By default, the Ranger data source of a common cluster can be accessed by Unix users.

Prerequisites

  • Check whether the cluster is in normal mode.
  • The Ranger component has been installed.

Procedure

  1. Log in to the MRS management console.
  2. Choose Clusters > Active Clusters, select a running cluster, and click its name to switch to the cluster details page.
  3. Click the Nodes tab and select the node group whose Node Type is Master.
  4. Go to the ECS page of the active Master node and click Remote Login.
  1. Log in to the active Master node as user root, go to the /opt/Bigdata/components/FusionInsight_HD_8.1.2.2/Ranger directory, and change the value of ranger.usersync.sync.source in the configurations.xml file to ldap.

    ranger.usersync.sync.source  
<value model="NoSec">ldap</value>

  2. Run the following commands on the active Master node to restart the controller process:

    su - omm

    sh /opt/Bigdata/om-server_8.1.2.2/om/sbin/restart-controller.sh

    When the controller process is restarted, the Manager page cannot be accessed for a short period of time, which is normal. After the controller process is restarted, you can access the MRS Manager page properly.

  3. Log in to FusionInsight Manager. For details, see Accessing FusionInsight Manager. Choose Clusters > Services > Ranger. In the upper right corner of the Dashboard page, click More and choose Synchronize Configuration.
  4. On the Ranger instance page, select the UserSync instance and choose More > Restart Instance.
  5. On the Dashboard page of the Ranger service, click RangerAdmin and choose Settings > Users/Groups/Roles to check whether LDAP users exist.
