Configuring the Public Network

If you have not already done so, configure the public network by performing the following steps

each node

root

Edit the network device file

/etc/sysconfig/network-scripts/ifcfg-eth#

, where # is the number

of the network device, and configure the file as follows:

DEVICE=eth0

ONBOOT=yes

IPADDR=<Public IP Address>

NETMASK=<Subnet mask>

BOOTPROTO=static

HWADDR=<MAC Address>

SLAVE=no

Edit the

/etc/sysconfig/network

file, and, if necessary, replace

localhost.localdomain

with the fully qualified public node name.

For example, the line for node 1 would be as follows:

HOSTNAME=node1.domain.com

Ty p e :

service network restart

Ty p e

ifconfig

to verify that the IP addresses are set correctly.

To check your network configuration, ping each public IP address from a client on the LAN

outside the cluster.

Connect to each node to verify that the public network is functioning and type

ssh

to verify that

ssh

is working.

Configuring the Private Network Using Bonding

Before you deploy the cluster, configure the private cluster network to allow the nodes to

communicate with each other. This involves configuring network bonding and assigning a private

IP address and hostname to each node in the cluster. To set up network bonding for Broadcom or

Intel NICs and configure the private network, perform the following steps on

each node

root

Add the following line to the

/etc/modules.conf

file:

alias bond0 bonding
