Compute node ~~~~~~~~~~~~ Configure network interfaces ---------------------------- #. 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. #. 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*. .. only:: ubuntu or debian a. Edit the ``/etc/network/interfaces`` file to contain the following: .. code-block:: ini # 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 .. only:: rdo a. Edit the ``/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME`` file to contain the following: Do not change the ``HWADDR`` and ``UUID`` keys. .. code-block:: ini DEVICE=INTERFACE_NAME TYPE=Ethernet ONBOOT="yes" BOOTPROTO="none" .. only:: obs a. Edit the ``/etc/sysconfig/network/ifcfg-INTERFACE_NAME`` file to contain the following: .. code-block:: ini STARTMODE='auto' BOOTPROTO='static' #. Reboot the system to activate the changes. Configure name resolution ------------------------- #. Set the hostname of the node to ``compute1``. #. .. include:: shared/edit_hosts_file.txt
