Configure DNS servers - AWS Elemental Conductor Live

Configure DNS servers

You can configure a node to use one or more DNS servers.

These rules apply to working with DNS on a node:

  • If at least one Ethernet interface on the node uses DHCP, you can only use the CLI to work with DNS.

  • If all the Ethernet interfaces have static addresses, you can work with DNS using the web interface or the CLI.

Where to perform the configuration

Make sure you perform the configuration on the correct nodes.

Node Work on this node?
Primary Conductor Live node Yes
Secondary Conductor Live node Yes
Each worker node Yes
To configure DNS using the web interface

See the information earlier on this page to determine if you can use the web interface.

  1. If the node is a Conductor Live node and if HA is currently enabled, disable it now. Conductor Live redundancy (HA, or high availability) must be disabled before you configure Ethernet interfaces. For instructions, see Disabling Conductor Live HA (high availability).

  2. For a Conductor Live node, on the Conductor Live web interface, go to the Settings page and choose Network. Then choose the Domain Name Servers tab.

    For a worker node, on the worker web interface, choose Settings from the main menu. Choose the Network tab, then choose Hostname, DNS, & Timing Server.

  3. Enter the IP address for the DNS server Choose Save. Another line appears, for you to enter another DNS server, if you want.

To configure DNS servers using the CLI

  1. If the node is a Conductor Live node and if HA is currently enabled, disable it now. Conductor Live redundancy (HA, or high availability) must be disabled before you configure Ethernet interface. For instructions, see Disabling Conductor Live HA (high availability).

  2. To configure DNS, see the Red Hat Networking Guide.
