Doug Hellmann e39304d4ae fix pdf build 
The PDF build does not include content multiple times if the same file
is included in a toctree more than once. That means we need to
restructure the guide to handle the common parts differently. This
approach merges some of the previously split sections back together
using inline prose to indicate where minor variations apply for
different operating systems but retaining separate files for cases where
the differences are significant.

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 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 or Debian:

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

      # 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 Red Hat or CentOS:

    • 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"

    For SUSE:

    • 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.
