Ha Service Configuration; Installing The Ha Software - Novell SLRS 8 Admin Manual

5 Setting up Administration and Branch Servers
During the configuration of the network settings, configure two interfaces in
addition to the public interface. Using two networks from the private range is
suggested, for example:
node1: eth0 192.168.1.1
node1: eth1 192.168.10.1 node2: eth1 192.168.10.2 (DRBD connect)
node1: eth2 192.168.100.1 node2: eth2 192.168.100.2 (Heartbeat connect)
After the installation, make sure all HA interfaces are connected correctly to
their counterparts.
Note: In the branch server template configuration files, a setup of only two
network cards, one for the public network and the Linux Heartbeat connection
and one for DRBD, is described.
Set the host names and the domain to the values stored in the LDAP directory.
Make sure that, on both nodes, the file /etc/hosts includes the other node.
Before continuing with the HA installation of Section 5.3.4, initialize your
primary branch server as for a stand-alone server (described in Section
on page 64) to create the needed configuration data and settings.
5.3.3 HA Service Configuration
To simplify a highly available configuration, the configuration files for the
DHCP and DNS service are soft-linked by the configuration scripts. For this
reason, the DHCP daemon must not run in chroot(1) environments. Choose
the configuration DHCPD_RUN_CHROOTED='no' in the file /etc/sysconfig/dhcpd.

5.3.4 Installing the HA Software

In addition to the BS software package installation described in Section 5.2,
install the following packages from the SUSE LINUX Enterprise Server Service
Pack CD by running rpm -ihv [packagename] in the order listed:
heartbeat-ldirectord-1.0.4-14
heartbeat-pils-1.0.4-14
heartbeat-1.0.4-14
heartbeat-stonith-1.0.4-14
drbd-0.6.6-152
The appropriate update kernel 2.4.21-138 for your hardware.
Now perform a reboot.
