I am trying to setup a tomcat cluster as told in the tomcat cluster
document. There are 3 PCs in my environment. All of them are
running RHEL AS 3.
apache (2.0.26) /w mod_jk (1.2.19) ip: 10.0.0.20
|
___________ | ________
| |
ip:10.0.0.10 10.0.0.11
tomcat1 tomcat2 (version 5.5.17 with jre
1.5.0_08)
ip:192.168.5.223 192.168.5.224
The 10.0.0.0/24 is the subnet for apache and tomcat, and
192.168.5.0/24 is the subnet for tomcat session replication/cluster.
The apache and tomcat part runs without problem. But I just can't
make the cluster part run successfully.
First, I got "No such device" error. So I insert
mcastBindAddress="192.168.5.223" in tomcat1 and
mcastBindAddress="192.168.5.224" in tomcat2, the problem is solved.
But I got another problem, inside the log, there is a line said,
"INFO: Manager [/jspSession]: skipping state transfer. No members
active in cluster group." I have search the internet, people say it
should be the problem of multicast. So I use the javagroup's
McastReceiverTest/McastSenderTest to test multicast, it works (some
people use tomcat-replication.jar, but I can't find it on the
internet now). Then I wonder if tomcat clusters are not sending
the correct message, I use tcpdump to capture the message. I can
see that tcp://192.168.5.223:4001 & tcp://192.168.5.224:4001 in the
capture log. Then I think it may be a tomcat version problem. So I
upgrade tomcat to 5.5.20, and then upgrade jre to 1.5.0_09, but
still no lucks. Now I really need the help from you.
Below the tomcat config and my PCs network config. ( just don't
want this mail become too large, I just post the tomcat2 config.
I've double check the config, the only different is the ip address).
