Configuring Your Network
This section provides information about configuring the public and private
cluster network.
NOTE: Each node in a network requires a unique public and private Internet protocol
(IP) address. An additional public IP address is required to serve as the virtual
IP address for the client connections and the connection failover. Therefore, a total
of three IP address are required for each node. The virtual IP address must belong
to the same subnet as the public IP. All public IP addresses, including the virtual
IP address, must be registered with the Domain Naming Service (DNS) and they
must be routable. For more information, see "IP Address and Name Resolution
Requirements" on page 12.
Depending on the number of NIC ports available, configure the interfaces as
shown in Table 2-1.
Configuring the Public Network
NOTE: Ensure that the public IP address is a valid and routable IP address.
NOTE: Each of the two bonded NIC ports for the private network must be on
separate PCI buses. For example, a bonded pair can consist of one on-board NIC
and one add-on NIC card.
To configure the public network on each node:
1
Log in as root .
2 Edit the network device file /etc/sysconfig/network-scripts/ifcfg-eth #,
where # is the number of the network device:
Table 2-1. NIC Port Assignments
