Hi,
I setup a three node cluster on my Mac and tested a fail over with
three nodes successfully. My next step was to setup tomcat on my
Windows 2000 machine too and migrate one of the nodes over there.
After completing the setup I tried fail over again, but it is not
working. The two nodes are failing over to each others on my Mac,
but tnever to the third node on the windows machine. The Apache2 web
server is running on the Mac and I use mod_jk to connect.
In the three server.xml file I just added an additional Host. Here
is the Engine portion from node2 on the Mac
...
<Engine name="Catalina" defaultHost="bml0042.yalepath.org"
jvmRoute="node2">
<Cluster
className="org.apache.catalina.ha.tcp.SimpleTcpCluster"/>
<Realm
className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Context path="" docBase="ROOT"
className="org.apache.catalina.ha.context.ReplicatedContext"/>
<Host name="bml0042.yalepath.org" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false"/>
<Host name="bml0039.yalepath.org" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false"/>
</Engine>
....
here is my workers.properties file from the conf directory of apache2:
...
worker.list = lbnodes,jkstatus
worker.lbnodes.type=lb
worker.lbnodes.balance_workers=node1,node2,node3
worker.jkstatus.type=status
worker.node1.type = ajp13
worker.node1.host = 10.84.2.42
worker.node1.port = 8009
worker.node1.lbfactor = 1
worker.node1.redirect=node2
worker.node2.type = ajp13
worker.node2.host = 10.84.2.42
worker.node2.port = 8109
worker.node2.lbfactor = 1
worker.node2.redirect=node3
worker.node3.type = ajp13
worker.node3.host = 10.84.2.39
worker.node3.port = 8209
worker.node3.lbfactor = 1
worker.node3.redirect=node1
worker.node1.sticky_session = True
worker.node2.sticky_session = True
worker.node3.sticky_session = True
worker.node1.sticky_session_force = False
worker.node2.sticky_session_force = False
worker.node3.sticky_session_force = False
....
The node3 on the Windows machine participates in the Cluster and
registers the other nodes, and even the session replication is
working, it is just the fail over that has the problem.
I do not want to run an IIS or even Apache2 on Windows, I want only
Tomcat there. It looks to me that although the workers.properties
are there but somehow JK knows only about the first two nodes on the
Mac and not the third one on the Windows 2000 machine.
Do have to put FQDN-ed values into jvmRoute like
bml0039.yalepath.org:/node3, or similar as Engine parameters ?? Do I
have to share out C;\node3 as a share ??
Any good advise, or pointers to the appropriate files where a cluster
is working on different machines with different OS-es?
Thanks ahead,
János
