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

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

    ubuntu or debian

    • Edit the /etc/network/interfaces file to contain the following:

      # The public network interface
auto INTERFACE_NAME
iface  INTERFACE_NAME inet manual
up ip link set dev $IFACE up
down ip link set dev $IFACE down

    rdo

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

      Do not change the HWADDR and UUID keys.

      DEVICE=INTERFACE_NAME
TYPE=Ethernet
ONBOOT="yes"
BOOTPROTO="none"

    obs

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

      STARTMODE='auto'
BOOTPROTO='static'

  3. Reboot the system to activate the changes.

Configure name resolution

  1. Set the hostname of the node to compute1.
