primarily involve Ubuntu. Other distributions may require
additional patches.

Controller node

Configure network interfaces

  1. Configure the first interface as the management interface:

    IP address: 10.0.0.11

    Network mask: 255.255.255.0 (or /24)

    Default gateway: 10.0.0.1

  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

    1. 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

    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"

    obs

    1. 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 controller.

  2. Edit the /etc/hosts file to contain the following:

    # controller
10.0.0.11       controller

# compute1
10.0.0.31       compute1

# block1
10.0.0.41       block1

# object1
10.0.0.51       object1

# object2
10.0.0.52       object2

    Warning

    Some distributions add an extraneous entry in the /etc/hosts file that resolves the actual hostname to another loopback IP address such as 127.0.1.1. You must comment out or remove this entry to prevent name resolution problems. Do not remove the 127.0.0.1 entry.

    Note

    To reduce complexity of this guide, we add host entries for optional services regardless of whether you choose to deploy them.
