    Configuring System Settings

    After installing the base image to all servers being used in the installation, and before running role provisioning scripts, perform the following steps to configure items specific to your environment.

    Perform these configuration steps each time you perform an initial installation or an upgrade to a new release.

    To configure system settings:

    1. Update /etc/resolv.conf with nameserver information specific to your system.
    2. Update /etc/sysconfig/network with the hostname and domain information specific to your system.
    3. Configure the LAN port with network information specific to your system:
      1. Use show ifconfig –a to determine which LAN port you are using, as this might not be obvious on some systems due to the ways interfaces can be named.
      2. Update the appropriate interface configuration file in /etc/sysconfig/network-scripts/ifcfg-<int name> using the following guidelines:
        • IPADDR = <IP of the host you want to assign>
        • NETMASK = <e.g. 255.255.255.0>
        • GATEWAY = <gateway router address>
        • BOOTPROTO — delete this, or change dhcp to static
        • Other settings can remain as is
