使用 Httpd mod_cluster 和 tomcat 进行负载平衡不起作用

我正在尝试使用 Httpd、mod_cluster 和 Tomcat 设置负载平衡器。我的 Httpd 和 Tomcat 运行在同一台服务器上，IP 为 192.168.9.73。这是我的 Httpd 配置-

Listen *:9999

<VirtualHost *:9999>

 ManagerBalancerName cluster

 <Directory />
  Order deny,allow
  Deny from none
  Allow from all
 </Directory>

 ProxyPass / balancer://cluster/ stickysession=JSESSIONID|jsessionid nofailover=On
 ProxyPassReverse / balancer://cluster/

 KeepAliveTimeout 300
 MaxKeepAliveRequests 0
 ServerAdvertise On
 AdvertiseGroup 224.0.1.105:23364
 AdvertiseFrequency 5
 <Location /mod_cluster_paas>
  SetHandler mod_cluster-manager
  Order deny,allow
  Deny from none
  Allow from all
 </Location>

</VirtualHost>

和 Tomcat server.xml-

<Engine name="jboss.web" defaultHost="localhost" jvmRoute="node1">
    <Listener className="org.jboss.modcluster.container.catalina.standalone.ModClusterListener" advertise="true" proxyList="192.168.9.73:9999"/>

    <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6">

          <Manager className="org.apache.catalina.ha.session.BackupManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true" mapSendOptions="6"/>

         <Channel className="org.apache.catalina.tribes.group.GroupChannel">

         <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/>

          <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="auto" port="5000" selectorTimeout="100" maxThreads="6"/>

         <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">

         <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>

          </Sender>

          <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>

          <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>

     <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/>

     </Channel>

     <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>

     </Cluster>
</Engine>

我按照本教程设置了负载平衡器，但它不起作用。在 httpd 错误日志中启动 httpd 和 tomcat 后，我​​收到此错误消息-

[Wed Mar 13 18:23:51 2013] [error] proxy: CLUSTER: (balancer://cluster). All workers are in error state

每当我尝试打开 192.168.9.73:9999

我的配置有误。按照 mod_cluster 页面上的教程并添加了 EnableMCPMReceive 属性。

mod_cluster参考链接。
