红帽全球峰会6.5. Adding a DNS Forward Zone in the CLI
Follow this procedure to add a DNS forward zone by using the command line (CLI).
Do not use forward zones unless absolutely required. Forward zones are not a standard solution, and using them can lead to unexpected and problematic behavior. If you must use forward zones, limit their use to overriding a global forwarding configuration.
When creating a new DNS zone, Red Hat recommends to always use standard DNS delegation using nameserver (NS) records and to avoid forward zones. In most cases, using a global forwarder is sufficient, and forward zones are not necessary.
Prerequisites
- You are logged in as IdM administrator.
- You know the Internet Protocol (IP) address of the DNS server to forward queries to.
Procedure
Use the
dnsforwardzone-addcommand to add a new forward zone. Specify at least one forwarder with the--forwarderoption if the forward policy is notnone, and specify the forward policy with the--forward-policyoption.[user@server ~]$ ipa dnsforwardzone-add forward.example.com. --forwarder=10.10.0.14 --forwarder=10.10.1.15 --forward-policy=first Zone name: forward.example.com. Zone forwarders: 10.10.0.14, 10.10.1.15 Forward policy: first
Verification
Use the
dnsforwardzone-showcommand to display the DNS forward zone you just created.[user@server ~]$ ipa dnsforwardzone-show forward.example.com. Zone name: forward.example.com. Zone forwarders: 10.10.0.14, 10.10.1.15 Forward policy: first
