I have two servers jboss 4.0.4.GA in cluster. The web server is apache
Apache/2.0.52 which is using module mod_jk/1.2.25 to load_balancing and
failover. The OS is RHEL AS 4.5. All this system run very well.
I'm trying to migrate this old system to a newer one. The new cluster has two
nodes jboss 4.0.4.GA, but the OS is RHEL 5.3 and web server Apache/2.2.3 which
is using modules proxy_module,proxy_ajp_module,proxy_balancer_module instead of
mod_jk.
I can't reproduce the behaviour of mod_jk with mod_proxy.
In old system I have the next config files:
/etc/httpd/conf/workers.properties
worker.list=loadbalancer,status
worker.nodo1.port=8009
worker.nodo1.host=localhost
worker.nodo1.type=ajp13
worker.nodo1.lbfactor=10
worker.nodo2.port=8009
worker.nodo2.host= 10.10.1.158
worker.nodo2.type=ajp13
worker.nodo2.lbfactor=30
worker.loadbalancer.type=lb
worker.loadbalancer.balance_workers=nodo1,nodo2
worker.loadbalancer.sticky_session=1
worker.status.type=status
/etc/httpd/conf/uriworkermap.properties
/jmx-console=loadbalancer
/jmx-console/*=loadbalancer
/web-console=loadbalancer
/web-console/*=loadbalancer
/*.jsp=loadbalancer
/*.do=loadbalancer
/*.asp=loadbalancer
/services/*=loadbalancer
/servlet/*=loadbalancer
/index.html=loadbalancer
/promo/*=loadbalancer
/sanvalentin=loadbalancer
/sanvalentin/*=loadbalancer
/JSON-RPC*=loadbalancer
-----
With this configuration the static contents was served by apache y the dynamic
contents are served by JBoss (*.jsp, *.do, *.asp, etc). Both contents could be
in the same directories. For this reason I used /*.do, /*.asp, /*.jsp in
uriworkermap.properties.
In other hand the configuration of mod_proxy is:
-----
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
<Proxy balancer://mycluster>
Order deny,allow
Allow from all
BalancerMember ajp://nodeA:8009 route=nodo1 retry=60 loadfactor=10
BalancerMember ajp://nodeB:8009 route=nodo2 retry=60 loadfactor=10
<Location / >
Allow From All
ProxyPass balancer://mycluster/ stickysession=JSESSIONID nofailover=on
lbmethod=byrequests
ProxyPassReverse balancer://mycluster/
<Location /balancer>
SetHandler balancer-manager
Order Deny,Allow
Deny from all
Allow from 192.100.30.161
ProxyStatus On
-------------------
With this configuration all the contents are served by jboss nodes.
If I change the <Location / > in order to use the form <Location /*.jsp > or
similar it doesn't forward the calls to the JBoss. I want to achieve the same
behaviour that I achieved with uriworkermap.properties.
In Addition I think the stickysession is not running. I've made a jsp
(whoami.jsp) who tell me what's the node which is serving the page. I've
detected the next behaviour:
>From a Browser I request the page whoami.jsp and when the response is given by
>the server A, If I refresh this page the next times, I get the response from
>server B. Why is not served by the server A?
Do you know what is happening and how could i get the same behaviour like the
mod_jk?
Thanks in advance
