Configuring the Public Network
NOTE: Ensure that your public IP address is a valid, routable IP address.
NOTE: The two bonded NIC ports for a private network should 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, do so by performing 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.
Configure the file as follows:
DEVICE=eth0
ONBOOT=yes
IPADDR=<Public IP Address>
NETMASK=<Subnet mask>
BOOTPROTO=static
HWADDR=<MAC Address>
SLAVE=no
3
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
4
Ty p e :
service network restart
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 outside the cluster.
7
Connect to each node to verify that the public network is functioning, and
type
ssh <public IP>
to verify that the
secure shell (ssh)
command is
working.
