Help with mod_cluster 1.0.8 GA setup on Windows
joaocunhalopes Mar 1, 2011 6:36 PMHello.
I have trying to get mod_cluster to work on windows.
I wish to avoid using advertise (multicast) so I have configured mod-cluster-jboss-beans.xml (property advertise was set to false; explicit IP/port was declared on property proxyList) like this:
<!-- Configure this node's communication with the load balancer -->
<bean name="HAModClusterConfig" class="org.jboss.modcluster.config.ha.HAModClusterConfig" mode="On Demand">
<!-- Comma separated list of address:port listing the httpd servers
where mod_cluster is running. -->
<property name="proxyList">192.168.1.20:6666</property>
<!-- URL prefix to send with commands to mod_cluster. Default is no prefix. -->
<!--property name="proxyURL"></property-->
<!-- mod_advertise is a small httpd module that advertises the
availability of httpd servers via multicast, allowing
ModClusterService to discover the httpd front-end instead of/in
addition to having them defined in proxyList. -->
<!-- Whether to listen for advertise messages -->
<property name="advertise">false</property>
<!-- Multicast address on which to listen for advertisements -->
<property name="advertiseGroupAddress">${jboss.modcluster.advertise.address,jboss.partition.udpGroup:224.0.1.105}</property>
<!-- Port to listen to for advertisements -->
<property name="advertisePort">${jboss.modcluster.advertise.port:23364}</property>
<!-- Comma delimited list of contexts that should *not* be auto-registered with httpd. -->
<!-- ROOT indicates the root context. -->
<!-- Context may be qualified by host using a colon, e.g. host1:context1 -->
<!-- If no host is defined, localhost is assumed. -->
<property name="excludedContexts">${jboss.modcluster.excludedContexts:ROOT,admin-console,invoker,jbossws,jmx-console,juddi,web-console}</property>
<!-- Security key the proxy is going to send with advertise messages.
Default is none. -->
<!--property name="advertiseSecurityKey"></property-->
<!-- Whether to use SSL to communicate with mod_cluster. Note this
has nothing to do with handling of https requests by JBoss Web -->
<property name="ssl">false</property>
<!-- Configuration values for the load balancer itself (must be the
same on all nodes in the cluster). These will be passed to the
load balancer. -->
<property name="stickySession">true</property>
<property name="stickySessionForce">false</property>
<property name="stickySessionRemove">false</property>
<property name="maxAttempts">1</property>
<property name="workerTimeout">-1</property>
</bean>
On the httpd "side" I am using Apache 2.2.17 and I have my httpd.conf setup like this:
ServerRoot "D:/Apache2.2"
ThreadsPerChild 250
MaxRequestsPerChild 0
# Required for Apache startup
LoadModule authz_host_module modules/mod_authz_host.so
# Module for server-status
LoadModule status_module modules/mod_status.so
ExtendedStatus On
# Modules for JBoss mod_cluster
LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
LoadModule slotmem_module modules/mod_slotmem.so
LoadModule manager_module modules/mod_manager.so
LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
LoadModule advertise_module modules/mod_advertise.so
Listen 192.168.1.20:6666
<VirtualHost 192.168.1.20:6666>
KeepAliveTimeout 60
MaxKeepAliveRequests 0
ManagerBalancerName mycluster
AdvertiseFrequency 5
</VirtualHost>
Listen 192.168.1.20:80
<VirtualHost *:80>
<Location /mcm>
SetHandler mod_cluster-manager
Order deny,allow
Deny from all
Allow from all
</Location>
<Location /server-status>
SetHandler server-status
Order deny,allow
Deny from all
Allow from all
</Location>
<Location /load-demo>
Order deny,allow
Deny from all
Allow from all
</Location>
</VirtualHost>
The "problem" that I have is the following: if on httpd.conf I use:
Listen 192.168.1.20:6666
<VirtualHost 192.168.1.20:6666>
KeepAliveTimeout 60
MaxKeepAliveRequests 0
ManagerBalancerName mycluster
ServerAdvertise Off
</VirtualHost>
I just can't get mod_cluster to work. Nothing is shown on the page
as oposed to the first configuration, where, with
Listen 192.168.1.20:6666
<VirtualHost 192.168.1.20:6666>
KeepAliveTimeout 60
MaxKeepAliveRequests 0
ManagerBalancerName mycluster
AdvertiseFrequency 5
</VirtualHost>
I can see the JBoss servers on the page
Before posting here I have read this:
http://docs.jboss.org/mod_cluster/1.1.0/html/faq.html#d0e4112
I know the above link is for 1.1.0 and that I'm using 1.0.8 GA.
Can anyone explain why with ServerAdvertise Off mod_cluster stops working?
Thank you.
