我正在 JBoss EAP 7 上验证我的应用程序。我的应用程序在独立模式下工作,但在集群模式下,我的应用程序被部署但我无法登录。我再次被重新路由到登录网址。
我已经使用 mod_cluster 设置了集群。
负载平衡器服务器日志中没有错误日志,集群的各个节点上也没有。
在我的测试环境中,我的负载均衡器和 2 个服务器节点在同一台机器上。我为 JBoss 节点提供了不同的端口和实例 ID 来区分节点。
我正在共享我的 mod_cluster.conf 和 JBoss Standalone-ha.xml 从集群中的一个节点中提取的内容。
以下是standalone-ha.xml 文件中的片段:
Modcluster 设置为:
<subsystem xmlns="urn:jboss:domain:modcluster:2.0">
<mod-cluster-config advertise-socket="modcluster" proxies="proxy1" balancer="testcluster" advertise="true" connector="ajp">
<dynamic-load-provider>
<load-metric type="busyness"/>
</dynamic-load-provider>
</mod-cluster-config>
</subsystem>
Undertow 设置如下:
<subsystem xmlns="urn:jboss:domain:undertow:3.1" instance-id="node1">
<buffer-cache name="default"/>
<server name="default-server">
<ajp-listener name="ajp" socket-binding="ajp"/>
<http-listener name="default" socket-binding="http" redirect-socket="https"/>
<host name="default-host" alias="localhost">
<location name="/" handler="welcome-content"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
</host>
</server>
<servlet-container name="default">
<jsp-config/>
<websockets/>
</servlet-container>
<handlers>
<file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
</handlers>
<filters>
<response-header name="server-header" header-name="Server" header-value="JBoss-EAP/7"/>
<response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>
</filters>
</subsystem>
Socket Binding Group的内容是:
<socket-binding-group name="standard-sockets" default-interface="public" port-offset="${jboss.socket.binding.port-offset:0}">
<socket-binding name="management-http" interface="management" port="${jboss.management.http.port:9990}"/>
<socket-binding name="management-https" interface="management" port="${jboss.management.https.port:9993}"/>
<socket-binding name="ajp" port="${jboss.ajp.port:8009}"/>
<socket-binding name="http" port="${jboss.http.port:8080}"/>
<socket-binding name="https" port="${jboss.https.port:8443}"/>
<socket-binding name="jgroups-mping" interface="private" port="0" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45700"/>
<socket-binding name="jgroups-tcp" interface="private" port="7600"/>
<socket-binding name="jgroups-tcp-fd" interface="private" port="57600"/>
<socket-binding name="jgroups-udp" interface="private" port="55200" multicast-address="${jboss.default.multicast.address:230.0.0.4}" multicast-port="45688"/>
<socket-binding name="jgroups-udp-fd" interface="private" port="54200"/>
<socket-binding name="modcluster" port="0" multicast-address="224.0.1.105" multicast-port="23364"/>
<socket-binding name="txn-recovery-environment" port="4712"/>
<socket-binding name="txn-status-manager" port="4713"/>
<outbound-socket-binding name="mail-smtp">
<remote-destination host="localhost" port="25"/>
</outbound-socket-binding>
<outbound-socket-binding name="proxy1">
<!-- host and port number of the load-balancer. -->
<remote-destination host="x.x.x.x" port="81"/>
</outbound-socket-binding>
</socket-binding-group>
mod_cluster.conf 的内容如下:
LoadModule proxy_cluster_module modules/mod_proxy_cluster.so
LoadModule cluster_slotmem_module modules/mod_cluster_slotmem.so
LoadModule manager_module modules/mod_manager.so
LoadModule advertise_module modules/mod_advertise.so
