33.11. Installing DNS Services Into an Existing Server
It is possible to install DNS services into an IdM server that was originally installed without them. To do this, make sure the ipa-server-dns package is installed, and then use the
ipa-dns-install utility.
Configuring DNS services using
ipa-dns-install follows the same principles as installing DNS with the ipa-server-install utility, as described in Section 2.3.3, “Installing a Server with Integrated DNS”.
For more information about
ipa-dns-install, see the ipa-dns-install(1) man page.
33.11.1. Setting up Additional Name Servers
33.11.1.1. Setting up Additional Name Servers
IdM adds the newly-configured IdM DNS server to the list of DNS servers in the
/etc/resolv.conf file. It is recommended to manually add other DNS servers as backup servers in case the IdM server becomes unavailable. For example:
search example.com ; the IdM server nameserver 192.0.2.1 ; backup DNS servers nameserver 198.51.100.1 nameserver 198.51.100.2
For more details about configuring
/etc/resolv.conf, see the resolv.conf(5) man page.
