Manual Configuration
Manually Configuring a Standalone Synchronization Server
Start by creating the directory
# 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
# cfagent --no-lock --verbose --no-splay
# /sbin/init.d/cfservd start
# cfrun -- --inform
# cfrun -v -- --verbose
# 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
# cp localhost.pub root-192.10.25.12.pub
# ccp /etc/rc.config.d/cfservd /etc/rc.config.d/cfservd
# ccp * /var/opt/dsau/cfengine/ppkeys
# cexec /sbin/init.d/cfservd start
# ccp csync csync.conf /etc/cmcluster/csync
Test the configuration by performing the following steps
Apply the package and start it
# cmapplyconf -P csync.conf # cmmodpkg -e csync
On a managed client, use the command
