12 Configuring Your Network
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:
NOTE: Ensure that the Gateway address is configured for the public network
interface. If the Gateway address is not configured, the grid installation
may fail.
DEVICE=eth0
ONBOOT=yes
IPADDR=<Public IP Address>
NETMASK=<Subnet mask>
BOOTPROTO=static
HWADDR=<MAC Address>
SLAVE=no
GATEWAY=<Gateway Address>
3
Edit the /etc/sysconfig/network file, and, if necessary, replace
localhost.localdomain with the qualified public node name.
For example, the command for node 1:
hostname=node1.domain.com
4
Ty p e service network restart to restart the network service.
5 Ty p e ifconfig to verify that the IP addresses are set correctly.
6 To check your network configuration, ping each public IP address from a
client on the LAN that is not a part of the cluster.
7 Connect to each node to verify that the public network is functioning.
Ty p e
ssh <public IP> to verify that the secure shell (ssh) command
is working.
