我正在尝试在独立模式下创建一个 JBoss AS 7.1.1 集群（一台机器上的两个实例，端口偏移为 100）。我正在使用 apache (ver 2.2.22) 和 mod_cluster(ver 1.2.0) 进行负载平衡。当我调出两个 JBoss 时，我可以看到两个节点都更新了集群视图。但是，我在 Jboss 中收到以下错误：

ERROR [org.jboss.modcluster.mcmp.impl.DefaultMCMPHandler]  (ContainerBackgroundProcessor[StandardEngine[jboss.web]]) Error [MEM: MEM: Can't read  node: {4}] sending command STATUS to proxy 127.0.0.1/127.0.0.1:6666, configuration will be reset

在 Apache 日志中，这是我所拥有的：

[notice] Parent: child process exited with status 255 -- Restarting.
[notice] Advertise initialized for process 4924
[notice] Apache/2.2.22 (Win64) PHP/5.3.13 mod_cluster/1.2.0.Final configured --   resuming normal operations

[notice] Child 2000: Starting thread to listen on port 80.
[notice] Child 2000: Starting thread to listen on port 80.
[warn] manager_handler STATUS error: MEM: Can't read node

看起来 apache 由于模块 mod_cluster_proxy.so 模块故障而崩溃。我可以从windows事件日志中弄清楚。这是我在事件日志中的内容：

Faulting application name: httpd.exe, version: 2.2.22.0, time stamp: 0x4faff1ba
Faulting module name: mod_proxy.so, version: 2.2.21.0, time stamp: 0x4f3494b7
Exception code: 0xc0000005
Fault offset: 0x0000000000003115
Faulting process id: 0x12b4
Faulting application start time: 0x01cf4735c4635dbb

谁能帮我解决这个问题？我必须使用不同版本的 mod_cluster 吗？我需要进行任何配置更改吗？这是我的配置：

独立-ha.xml

<subsystem xmlns="urn:jboss:domain:modcluster:1.0">
        <mod-cluster-config advertise-socket="modcluster" proxy-list="127.0.0.1:6666">
            <dynamic-load-provider>
                <load-metric type="busyness"/>
            </dynamic-load-provider>
        </mod-cluster-config>
</subsystem>

apache中的httpd.conf：

Listen 127.0.0.1:6666
<VirtualHost 127.0.0.1:6666>
<Directory />
 Order deny,allow
 Deny from all
 Allow from 127.0.0
</Directory>

KeepAliveTimeout 300
MaxKeepAliveRequests 0    
AdvertiseFrequency 5
ManagerBalancerName mycluster
EnableMCPMReceive

<Location /mod_cluster-manager>
   SetHandler mod_cluster-manager
   Order deny,allow
   Deny from all
   Allow from 127.0.0
   AllowDisplay On
</Location>

</VirtualHost>

请让我知道如何解决这个问题..

不，这绝对不是配置错误。请在1.2.6中试用，并继续关注 1.2.9 和 1.3.x 版本...

编辑：为社区构建的最新最好的版本是mod_cluster 1.3.1.Final。
