When i 1st server goest down then 2nd server should takeover 1st, but when i am testing my setup, i found that heartbeat is not working when i stop httpd service and heartbeat works fine when ever i restart/start/stop heartbeat service. And i also found that logs are getting in for "httpd stop" even in /var/log/ha-log but "httpd stop" logs found in /var/log/messages . Below is the configuration file output. /etc/ha.d/ha.cf logfile /var/log/ha-log logfacility local0 warntime 5 keepalive 2 deadtime 15 initdead 60 bcast eth1 udpport 694 auto_failback on node web1 node web2 /etc/ha.d/haresources web2 192.168.1.55 httpd /etc/ha.d/authkeys auth 1 1 sha1 password /etc/hosts 192.168.1.52 web2 192.168.1.51 web1 Thank You.
