Configuring Your Network
This section guides you to configure the public and private cluster network.
NOTE: Each node 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. 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.
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.
If you have not already configured the public network, perform the following
steps 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:
DEVICE=eth0
ONBOOT=yes
IPADDR=<Public IP Address>
