Compute node

To configure networking:

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

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

   1. 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"

3. Restart networking:

   # service network restart

To configure name resolution:

• Edit the /etc/hosts file to contain the following:

  # compute1
  10.0.0.31       compute1
  
  # controller
  10.0.0.11       controller
