1.2. Installing and Configuring the KDC

To use Kerberos with HDP, either use an existing KDC or install a new one for HDP only. The following gives a very high level description of the installation process. For more information, see RHEL documentation , CentOS documentation, SLES documentation. or Ubuntu and Debian documentation.

  1. Install the KDC server:

    • On RHEL, CentOS, or Oracle Linux, run:

      yum install krb5-server krb5-libs krb5-auth-dialog  krb5-workstation
    • On SLES, run:

      zypper install krb5 krb5-server krb5-client
    • On Ubuntu or Debian, run:

      apt-get install krb5 krb5-server krb5-client
      [Note]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:

  2. Update the KDC configuration by replacing EXAMPLE.COM with your domain and kerberos.example.com with the FQDN of the KDC host; the configuration files are located:

    • On RHEL, CentOS, or Oracle Linux:

      • /etc/krb5.conf

      • /var/kerberos/krb5kdc/kdc.conf.

    • On SLES:

      • /etc/krb5.conf

      • /var/lib/kerberos/krb5kdc/kdc.conf

    • On Ubuntu or Debian:

      • /etc/krb5.conf

      • /var/kerberos/krb5kdc/kdc.conf.

  3. Copy the updated krb5.conf to every cluster node.
