Chapter 20. Complete working example

Following are a set of example configuration files for a complete working example.
Proxy Server

A proxy server listening on localhost:

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 127.0.0.1:6666
<VirtualHost 127.0.0.1:6666>

    <Directory />
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
    </Directory>

    KeepAliveTimeout 60
    MaxKeepAliveRequests 0

    ManagerBalancerName mycluster
    ServerAdvertise On
    AdvertiseFrequency 5

</VirtualHost>

<Location /mod_cluster-manager>
    SetHandler mod_cluster-manager
    Order deny,allow
    Deny from all
    Allow from 127.0.0.1
</Location>
JBoss Web Client Listener

Following are the listener definitions for JBOSS_EAP_DIST/server/PROFILE/deploy/jbossweb.sar/server.xml.

<!-- Non-clustered mode -->
<Listener className="org.jboss.web.tomcat.service.deployers.MicrocontainerIntegrationLifecycleListener" delegateBeanName="ModClusterService"/>
<!-- Clustered mode
 Listener className="org.jboss.web.tomcat.service.deployers.MicrocontainerIntegrationLifecycleListener" delegateBeanName="HAModClusterService"/-->
JBoss Web Client Service Dependencies

Following are the required dependencies for the WebServer bean in JBOSS_EAP_DIST/server/PROFILE/deploy/jbossweb.sar/META-INF/jboss-beans.xml. Add them to the existing dependencies.

<bean name="WebServer" class="org.jboss.web.tomcat.service.deployers.TomcatService">
  <!-- ... -->
  <depends>ModClusterService</depends><!-- Non-clustered mode -->
  <!--depends>HAModClusterService</depends--><!-- Clustered mode -->
  <!-- ... -->
</bean>
Example iptables Firewall Rules

Following are a set of example firewall rules using iptables, for a cluster node on the 192.168.1.0/24 subnet.

/sbin/iptables -I INPUT 5 -p udp -d 224.0.1.0/24 -j ACCEPT -m comment --comment "mod_cluster traffic"
/sbin/iptables -I INPUT 6 -p udp -d 224.0.0.0/4 -j ACCEPT -m comment --comment "JBoss Cluster traffic"
/sbin/iptables -I INPUT 9 -p udp -s 192.168.1.0/24 -j ACCEPT -m comment --comment "cluster subnet for inter-node communication"
/sbin/iptables -I INPUT 10 -p tcp -s 192.168.1.0/24 -j ACCEPT -m comment --comment "cluster subnet for inter-node communication"
/etc/init.d/iptables save
