- I think this is what worker.list should look like:
worker.list=pub-lb
Aaaah, right. The above won't work, the lb worker needs to be in the
list, not the members of the lb. with recent versions of mod_jk you
would find a message in the log, that the worker "pub-lb" used in your
JkMount isn't known to mod_jk (because it is missing in the list attribute).
- You might also need for every balance_worker the
worker.pub-app0x.redirect=machine_name_where_the_session_from_this_machine_should_be_redirected
You can use it if you have a very special idea, which node should fail
over to which other node, but you can omit it and the balancer will
choose one on a per request basis, if there is a problem with a node.
- For the load balance worker you might need something like:
worker.pub-lb.sticky_session_force=False
worker.pub-lb.sticky_session=True
Those are both defaults.
