It is enough to start Heartbeat at boot time (if its right configured.) Then heartbeat is the one, who starts sshd and httpd after itself is started on the primary node (the preferred one is the one which you declared with the first in /etc/ha.d/haresources)
cat /etc/ha.d/haresources server1 sshd httpd server1 (primary) /etc/init.d/heartbeat (start at boot) /etc/init.d/sshd (started by heartbeat at boot) /etc/init.d/httpd (started by heartbeat at boot) server2 (secondary) /etc/init.d/heartbeat (start at boot) /etc/init.d/sshd (started by heartbeat, when server1 is down) /etc/init.d/httpd (started by heartbeat, when server1 is down) To you power-question: When both nodes are affected by the power outage and you'll start them your resources will run on server1, again. When always one server is running you can control the switching of the resources (when the other member joines the cluster) with the auto_fallback option in /etc/ha.d/ha.cf. Please correct someone, if something is wrong. Regards Florian -----Ursprüngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Doug Lochart Gesendet: Mittwoch, 13. Februar 2008 18:19 An: General Linux-HA mailing list Betreff: [Linux-HA] resource script question (runlevel config) I have read a few tutorials now. Some mention turning off highly available services and some do not mention it. I am making 'sshd' and 'httpd' highly available on my ha cluster. Once I have everything configured one tutorial said to make sure that your services AND heartbeat are configured NOT to start at boot time on both servers. I understand this during the testing aspect but when this is ready to go live I believe this is the way it should be: server1 (primary) /etc/init.d/heartbeat (start at boot) /etc/init.d/sshd (does not start at boot ?? ) /etc/init.d/httpd ( does not start at boot ??) server2 (secondary) /etc/init.d/heartbeat (start at boot) /etc/init.d/sshd ( does not start at boot ) /etc/init.d/httpd ( does not start at boot ) Could someone please look at my above assumptions and correct me if I am wrong. I also assume that if server1 went down and server 2 became primary that is a building wide power outage occurred that when power was restored that server2 would still know it was primary. thanks Doug -- What profits a man if he gains the whole world yet loses his soul? _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
