Compute node

Configure network interfaces

  1. Configure the first interface as the management interface:

    IP address: 10.0.0.31

    Network mask: 255.255.255.0 (or /24)

    Default gateway: 10.0.0.1

    Note

    Additional compute nodes should use 10.0.0.32, 10.0.0.33, and so on.

  2. The provider interface uses a special configuration without an IP address assigned to it. Configure the second interface as the provider interface:

    Replace INTERFACE_NAME with the actual interface name. For example, eth1 or ens224.

  • Edit the /etc/sysconfig/network/ifcfg-INTERFACE_NAME file to contain the following:

    STARTMODE='auto'
    BOOTPROTO='static'
  1. Reboot the system to activate the changes.

Configure name resolution

  1. Set the hostname of the node to compute1.
