4.4.3. Reverting to Internal DNS Service
You can revert to using Satellite Server and Capsule Server as your DNS providers. You can use a backup of the answer file that was created before configuring external DNS, or you can create a backup of the answer file. For more information about answer files, see Configuring Satellite Server.
Procedure
On the Satellite or Capsule Server that you want to configure to manage DNS service for the domain, complete the following steps:
Configuring Satellite or Capsule as a DNS Server
If you have created a backup of the answer file before configuring external DNS, restore the answer file and then enter the
satellite-installercommand:# satellite-installer
If you do not have a suitable backup of the answer file, create a backup of the answer file now. To configure Satellite or Capsule as DNS server without using an answer file, enter the following
satellite-installercommand on Satellite and each affected Capsule:# satellite-installer \ --foreman-proxy-dns=true \ --foreman-proxy-dns-managed=true \ --foreman-proxy-dns-provider=nsupdate \ --foreman-proxy-dns-server="127.0.0.1" \ --foreman-proxy-dns-tsig-principal="foremanproxy/satellite.example.com@EXAMPLE.COM" \ --foreman-proxy-dns-tsig-keytab=/etc/foreman-proxy/dns.keytabFor more information,see Configuring DNS, DHCP, and TFTP on Capsule Server.
After you run the satellite-installer command to make any changes to your Capsule configuration, you must update the configuration of each affected Capsule in the Satellite web UI.
Updating the Configuration in the Satellite web UI
- Navigate to Infrastructure > Capsules.
- For each Capsule that you want to update, from the Actions list, select Refresh.
Configure the domain:
- Navigate to Infrastructure > Domains and click the domain name that you want to configure.
- In the Domain tab, set DNS Capsule to the Capsule where the subnet is connected.
Configure the subnet:
- Navigate to Infrastructure > Subnets and select the subnet name.
- In the Subnet tab, set IPAM to DHCP or Internal DB.
- In the Domains tab, select the domain that you want to manage using Satellite or Capsule.
- In the Capsules tab, set Reverse DNS Capsule to the Capsule where the subnet is connected.
- Click Submit to save the changes.
