Manual Configuration
Start by creating the directory
Manually Configuring a Standalone Synchronization Server
# mkdir -p /var/opt/dsau/cfenginemaster/inputs
# cp localhost.pub root-10.0.0.5.pub
# /opt/dsau/sbin/cfkey # /var/opt/dsau/cfengine/ppkeys
# cfrun -v -- --verbose
# /sbin/init.d/cfservd start
# cfagent --no-lock --verbose --no-splay
# cfrun -- --inform
# mkdir -p /csync/dsau/cfenginemaster/masterfiles
Initial Serviceguard Package Preparation
List Managed Clients in cfrun.hosts
Policyhost = csync.abc.xyz.com
# /opt/dsau/sbin/cfkey
Edit the cfservd.conf File
# cexec /sbin/init.d/cfservd start
# ccp /etc/rc.config.d/cfservd /etc/rc.config.d/cfservd
# cp localhost.pub root-192.10.25.12.pub
# ccp * /var/opt/dsau/cfengine/ppkeys
# cmapplyconf -P csync.conf # cmmodpkg -e csync
Test the configuration by performing the following steps
# ccp csync csync.conf /etc/cmcluster/csync
Apply the package and start it
On a managed client, use the command

Configuration Data for clogwizard
Using the Log Consolidation Wizard
Opt/dsau/sbin/clogwizard
Answer yes y or press Enter. The next question is
Where N is the expected number of clients
Answer yes y. The wizard then prompts
If these choices are correct, continue
Next prompt is
Log files that reside on this cluster can be consolidated
Consolidated package logs would be located here

Enter the ssh port to be used for port forwarding
Manually Configuring a Standalone Log Consolidation Server
Manually Configuring Log Consolidation
Replace the %UDPLOOPBACKLOG% token with
# /sbin/init.d/syslogd stop # /sbin/init.d/syslogd start
For example, for TCP
Add the following lines
Create the following symbolic link
Change the Clogconfigured line to
If using the TCP protocol, add
Log Consolidation Configuration
SYSLOGDOPTS=-D -N
KEEPALIVE% tokens with appropriate values
UDPLOOPBACKSOURCE% and %UDPLOOPBACKLOG% tokens
Creating the clog Package
If consolidating package logs of this cluster, add
If using VxVM, comment out the LVM Volume Group line
Distribute it cluster-wide
Testing and Starting the clog Package
Then use cmviewcl to make sure it is running
Using VxVM Instead of LVM
