1.2. Installing and Configuring the KDC

To use Kerberos with HDP you can either use an existing KDC or install a new one just for HDP's use. The following gives a very high level description of the installation process. To get more information see RHEL documentation , CentOS documentation, SLES documentation. or Ubuntu documentation.

To install a new version of the server:

[On RHEL or CentOS]
yum install krb5-server krb5-libs krb5-auth-dialog  krb5-workstation 

[On SLES]
zypper install krb5 krb5-server krb5-client

[On Ubuntu]
apt-get install krb5 krb5-server krb5-client

	Note
	The host on which you install the KDC must itself be secure.

When the server is installed you must edit the two main configuration files, located by default here:

[On RHEL or CentOS]

[On SLES]

[On Ubuntu]

Use these files to specify the realm by changing EXAMPLE.COM and example.com to case-matched version of the domain name for the realm and changing the KDC value from kerberos.example.com to the fully qualified name of the Kerberos server host.

The updated version of /etc/krb5.conf should be copied to every node in your cluster.
