17.4. Adding or Updating DNS Services After Installation
DNS can be configured as part of the IdM server installation, simply by using the
--setup-dns
option. If DNS is not configured then, it can be configured later using the ipa-dns-install
command.
The
ipa-dns-install
command also updates the DNS services on the IdM server.
[root@server ~]# ipa-dns-install -p secret --ip-address=1.2.34.56 --no-forwarders
-p
gives the password for the Directory Manager user in the 389 Directory Server. All of the DNS entries are stored in the LDAP directory, so this directory must be accessed to add the DNS configuration.--ip-address
gives the IP address for the master DNS server.--no-forwarders
means that there are no forwarders used with the DNS service, only root servers. Alternatively, use the--forwarder
option to define a forward to use; to specify multiple forwarders, use the--forwarder
option multiple times.- Reverse DNS is configured automatically. It is possible to disable reverse DNS by using the
--no-reverse
option.If an existing reverse DNS zone is already configured, using the--no-reverse
option uses the existing reverse zone rather than creating a new reverse zone. - The IdM server, unless it is explicitly disabled, leaves a persistent search open with its Directory Server and capture any new zone changes immediately.
