Hi all,
First I'm french so sorry in advance for my English...
I have to use Heartbeat for High Availability between 2 Tomcat 5.5 servers
under Linux RedHat 5.3. The first server is active, the other one is passive.
The master is called servappli01, with IP address 186.20.100.40, the slave is
called servappli02, with IP address 186.20.100.39.
I configured a virtual IP 186.20.100.41. Each Tomcat is not launched when
server is started, this is Heartbeat which starts Tomcat when it's running.
My problem is : When heartbeat is started on the first server, then on the
second server, the VIP is assigned to the 2 servers ! also, Tomcat is started
on each server, and each node see the other node as "dead" !
Here is my configuration :
ha.cf file (the same on each server) :
logfile /var/log/ha-log
debugfile /var/log/ha-debug
logfacility none
keepalive 2
warntime 6
deadtime 10
initdead 90
bcast eth0
node servappli01 servappli02
auto_failback yes
respawn hacluster /usr/lib/heartbeat/ipfail
apiauth ipfail gid=haclient uid=hacluster
haresources file (the same on each server) :
servappli01 IPaddr::186.20.100.41/24/eth0 tomcat
Result of ifconfig command on the first server (servappli01) :

Result of "/usr/bin/cl_status nodestatus servappli02" command on servappli02 :

And of course, if I kill Tomcat on master server, there's no switch to the
second server (a call to a webapp using the VIP doesn't work).
Can somebody help me please ?
I guess there's is something wrong but I don't know what !
Thanx
Mathieu
