Hi, I have lvs cluster of 3 nodes, on each node i have apache1.3 + tomcat4.1.12+mod_jk serving identical data. The http service on lvs is configured with persistent connection. So in normal operation i want that apache on each node will route requests to tomcat on the same node.
In addition if ,for example, i want to take down tomcat on one node, then i would like that apache on the same node will start routing requrests to the other two tomcats on the other nodes. Now if the tomcat comes back then i would like to continue to route requests only with an old session to to the other two tomcats. How can i enable this with load balancing in mod_jk? As i understand this can be done with setting local_worker=1 for all tomcat workers or only for the local tomcat worker. and how do i tell apache to forward the requests to load balancers on the other two nodes? How apache knows what there are other two remote load balancers, i.e should i somehow add them to local worker.properties? what lbfactor values should i give to the local and remote tomcat workers? How can i take down the tomcat cleanly, so that it goes down only after all old sessions to it end. As i have read in Workers HowTo this can be done with some special port if i set local_worker_only=1 for the load balancer worker, but how i switch this port off before shuting down tomcat? Or the old sessions can be just routed to another load balancers. If so then how?
