[lvs-users] ldirectord and tomcat cluster

[Darren.Mansell at opengi.co.uk]

During failover, you will lose sessions from the node that has gone
away. New connections will be sent to the remaining real server(s).

I asked the same thing 3 months ago ;)

Happy new year to you too.

Hi Darren, again ;-)

what you do is .... check the source IP and route it always to the same
tomcat node?
It this is true - what's about fail-over? This does not work then.
 
In my scenario  the webapps store lots of information in memory and
share it between each nodes.
So I am freed during a breakdown.
Isn't it better this way?

Whishing you a happy new Year!
Andreas

Hello Andreas.

I don't do session replication with Tomcat, I found it not to work very
well. Instead I just set anything you need sessions on to be source hash
scheduler.

Hello list,

I hope you can help all users who share this same problem:

I use a 2 cluster node running on each tomat with session replication
because I need load balancing (ldirector/ipvs) and on each node the same
session information.

I configured tomcat like described here:
http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html

It seems to work well if I do not use ldirectord for balancing.
(actually it checks port 80 [apache] )

virtual=10.10.11.139:80
        checktype=negotiate
        fallback=127.0.0.1:80
        protocol=tcp
        real=10.10.11.137:80 gate
        real=10.10.11.138:80 gate
        receive="Still alive"
        request="/test.html"
        scheduler=wlc
        service=http


But if I activate ldirectord for port 8080 (tomcat) then I get in my web
applications lots of "page can not be displayed" messages.

Can anybody explain me why this happens or show how to configure it
correctly?

Thank you.

Best regards
Andreas
