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 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*.
|
|
|
|
For Ubuntu:
|
|
|
|
* Edit the ``/etc/network/interfaces`` file to contain the following:
|
|
|
|
.. code-block:: bash
|
|
|
|
# The provider network interface
|
|
auto INTERFACE_NAME
|
|
iface INTERFACE_NAME inet manual
|
|
up ip link set dev $IFACE up
|
|
down ip link set dev $IFACE down
|
|
|
|
For RHEL or CentOS:
|
|
|
|
* Edit the ``/etc/sysconfig/network-scripts/ifcfg-INTERFACE_NAME`` file
|
|
to contain the following:
|
|
|
|
Do not change the ``HWADDR`` and ``UUID`` keys.
|
|
|
|
.. code-block:: bash
|
|
|
|
DEVICE=INTERFACE_NAME
|
|
TYPE=Ethernet
|
|
ONBOOT="yes"
|
|
BOOTPROTO="none"
|
|
|
|
For SUSE:
|
|
|
|
* Edit the ``/etc/sysconfig/network/ifcfg-INTERFACE_NAME`` file to
|
|
contain the following:
|
|
|
|
.. code-block:: bash
|
|
|
|
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
