Re: [jetty-users] Sticky load balancing with Jetty
|
I second haproxy for load balance. It has also heat-beat checking and graceful request redirection when a node(Jetty in this case) stops. Very useful for "real" hotdeploy configs i.e. change app without interrupting service.

We use HAProxy (http://haproxy.1wt.eu) as a load-balancing solution. It has a configuration option for session-stickiness. I don't know if Apache can be configured for sticky sessions or not, but it does not appear to be set in the config you posted.
Hope that helps.

Hi,
I first sent to the SF mailing list but got no replies and then came across
this mailing list. Hope to hear from someone. By the way, i'm using
jetty 6 if that matters.
Thanks in advance.

Hi all,
I'm
trying to front multiple jetty instances with apache. Did bit of
googling and ended up with a configuration which does pass my requests
to those instances in round robin fashion. However there is no
stickyness coming up with those jetty instances. I'm starting my them
something like this:
Server server1 = new Server(9990);
HashSessionIdManager sessionManager1 = new HashSessionIdManager();
sessionManager1.setWorkerName("jetty1");
server1.setHandler(new HelloHandler(9990, sessionManager1));
server1.setSessionIdManager(sessionManager1);
server1.start();
server1.join();
And my apache has the following configuration:
ProxyPass /balancer balancer://mycluster/context stickysession=JSESSIONID|jsessionid nofailover=On
<Proxy balancer://mycluster>
BalancerMember http://localhost:9990 route=jetty1
BalancerMember http://localhost:9992 route=jetty2
</Proxy>
But
for some reason, i don't see those jsessionid or JSESSIONID request
parameters coming in my requests (or cookies). Any idea what i might be
doing wrong?
Thanks in advance.
