29.3 Installing Heartbeat Packages
The following Heartbeat 3 packages are required for use with GroupWise:
Š heartbeat-2.0.7-1.2
(http://www.novell.com/products/linuxpackages/suselinux/
heartbeat.html)
Š
heartbeat-pils-2.0.7-1.2
(http://www.novell.com/products/linuxpackages/
suselinux/heartbeat-pils.html)
Š heartbeat-stonith-2.0.7-1.2
(http://www.novell.com/products/linuxpackages/
suselinux/heartbeat-stonith.html)
These packages are not included in a default SLES 10 installation. You must select them manually,
then the SLES 10 installation process installs them for you.
29.4 Configuring Heartbeat
Set up Heartbeat 2 on each node in the cluster by following the instructions provided in Installing a
Heartbeat 2 Cluster Using YaST in the
SUSE Linux Enterprise Server 10 Installation and
Administration Guide (http://www.novell.com/documentation/sles10/pdfdoc/sles_admin/
sles_admin.pdf) . The setup process creates basic Heartbeat configuration files:
Š
/etc/ha.d/ha.cf
(http://www.linux-ha.org/ha.cf)
This is the main Heartbeat configuration file. The default file provides the names of the nodes
in the cluster, sets up communication among them, and performs other basic cluster setup. For
convenience and for best performance with GroupWise, add the following lines to the
ha.cf
file:
use_logd yes
keepalive 2
deadtime 30
warntime 10
initdead 120
To configure the
logd
daemon referenced in the first line above, copy the
/usr/share/
doc/packages/heartbeat/ha_logd.cf
file to
/etc/ha.d
. Remove the comment
character (#) from the
debugfile
and
logfile
lines. If desired, change the directories
where log files are stored.
In order for the nodes to communicate with each other, you must configure each node so that
the Heartbeat UDP port of 694 is open. You must copy the customized
ha.cf
to each node in
the cluster.
Š
/etc/ha.d/authkeys
(http://www.linux-ha.org/authkeys)
This file provides an authentication string and must not be readable by any user other than
root
. After providing the authentication string as
root
, set the mode to 0400 or 0600. You
must copy the
authkeys
file to each node in the cluster.
Š /var/lib/heartbeat/crm/cib.xml
(http://www.linux-ha.org/
ClusterResourceManager/DTD1.0/Annotated)
This cluster resource manager (CRM) file is created automatically by Heartbeat when you use
the HA Management Client to create cluster resources, resource groups, constraints, etc., as
described in
Chapter 31, “Setting Up a Heartbeat Cluster,” on page 297 . Do not manually
modify the
cib.xml
file after starting Heartbeat.
