4. Initial DNS Configuration

Similar to DHCP, configuration of DNS via cobbler also works through template files.

First you again have to enable DNS management by changing the corresponding setting in /etc/cobbler/settings:

manage_dns: 1

Also edit the bind_master IP to the master IP in the cluster network:

bind_master: 192.168.16.1

Restart the cobblerd service to load these changes.

Any subsequent cobbler sync commands will then generate a new BIND configuration file /etc/named.conf based on /etc/cobbler/named.template and reload the BIND daemon.

Modify the options section in that template to allow access from both management and cluster subnets, similar to what was done in the previous exercise. However, you do not need to add the zone definitions just yet. We will learn how to do this in a later section.

Update your named.conf by running cobbler sync.
