Update the configuration files
Now that the Management Node can communicate with other devices in the
cluster take the following steps:
1. Update /etc/modules.conf with the following lines:
alias eth0 e1000
alias eth1 e1000
alias eth2 e1000
2. Edit or create the /etc/sysconfig/network/ifcfg-ethx file and make sure it
contains the following directives:
BOOTPROTO="static"
BROADCAST="172.20.255.255"
IPADDR="172.20.0.1"
NETMASK="255.255.0.0"
NETWORK="172.20.0.0"
STARTMODE="onboot"
3. Edit or create the /etc/sysconfig/network/ifcfg-eth2 file and customize it with
site specific network information. It should contain the same directives as
ifcfg-eth1
.
4. Update the /etc/resolv.conf file with the following lines:
search clusters.com (any other site specific domains)
nameserver 172.20.0.1
5.
Populate the /var/named directory using the named files found on the diskette
shipped with the Cluster 1350.
6. Copy over the downloaded /etc/named.conf and /etc/hosts files.
7.
Edit the /etc/named.conf file and add any site specific nameservers to the
forwarders section. For example:
options {
directory "/var/named’;
forwarders {
192.168.119.10;
192.168.119.11;
};
forward only;
8.
Edit the /etc/sysconfig/dhcpd file. Change the DHCPD_INTERFACE directive
to the following:
DHCPD_INTERFACE="eth0 eth1"
9. Enable the named, dhcpd, and NFS services by issuing the following
command:
# chkconfig nfsserver on
# chkconfig named on
# chkconfig dhcpd on
