Configuring System Settings
After installing the base image on 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:
- Update the
/etc/resolv.conffile with name server information specific to your system. - Update the
/etc/sysconfig/networkfile with the hostname and domain information specific to your system. - Configure the LAN port with network information specific
to your system:
- Use the show ifconfig –a command 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.
- 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 unchanged.
