Firstly, install 2 identical Linux "base system" on the machines (cengaver1-cengaver2) with the following packets: heartbeat, heartbeat-ldirectord, heartbeat-pils, heartbeat-stonith.. Secondly, connect the machines to eachother in 2 way; one from local area (136.10.199.97 - 136.10.199.98) and one by cross (99.99.99.101 - 99.99.99.102). Thirdly, configure the heartbeats; On the first machine edit "ha.cf" and make the following changes. cengaver1:/ # more /etc/ha.d/ha.cf logfile /var/log/ha-log logfacility local0 keepalive 2 deadtime 30 warntime 10 initdead 120 udpport 694 auto_failback off watchdog /dev/watchdog node cengaver1 node cengaver2 ucast eth1 136.10.199.98 ucast eth2 99.99.99.102 On the second machine, edit "ha.cf" and make the following changes. cengaver2:~ # more /etc/ha.d/ha.cf logfile /var/log/ha-log logfacility local0 keepalive 2 deadtime 30 warntime 10 initdead 120 udpport 694 auto_failback off watchdog /dev/watchdog node cengaver2 node cengaver1 ucast eth1 136.10.199.97 ucast eth2 99.99.99.101 Now, it is time to configure the shared resources (iSCSI, vsFTPd and SharedIP(136.10.199.99)). Edit the "haresources" file of the both machines and make the following changes; cengaver1:/ # more /etc/ha.d/haresources cengaver1 136.10.199.99 iscsi vsftpd Your system is prepared for the action! reboot first machine and then the second.
