【中文标题】我无法让会话复制与 Wildfly 10 一起使用【英文标题】：I can not get session replication to work with wildfly 10 【发布时间】：2016-12-25 06:08:35 【问题描述】：我们已将 httpd 作为负载均衡器放在 Wildfly 前面。我正在使用 Wildfly 10.1.0。
我有 3 台机器，一台主机，两台从机。
在我的主人的 domain.xml 我有：

在从属 1 的 hosts.xml 中，我有：
<servers>
<server name="server-web1" group="mycluster" auto-start="true">
<jvm name="jvm-web1">
<heap size="1024m" max-size="3072m"/>
<permgen size="1024m" max-size="1024m"/>
<jvm-options>
<option value="-server"/>
<option value="-d64"/>
</jvm-options>
</jvm>
</server>
</servers>
在我的从属 2 的 hosts.xml 中，我有：
<server name="server-web2" group="mycluster" auto-start="true">
<jvm name="jvm-web2">
<heap size="1024m" max-size="3072m"/>
<permgen size="1024m" max-size="1024m"/>
<jvm-options>
<option value="-server"/>
<option value="-d64"/>
</jvm-options>
</jvm>
</server>
</servers>
所有服务器都可以正常启动，并且在我拥有的日志中：

我遇到的问题是会话不会在两台服务器之间复制。负载平衡没有问题。 如果我停止从站 1，我会切换到从站 2，但会话不存在，第二台服务器会为我创建一个新的会话 ID。
我确实添加了可分发到我的 web.xml。
我是否在配置中遗漏了什么？
感谢您的帮助。
【问题讨论】：
您是否按照指示here ？ 【参考方案1】：问题出在
<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"/>
我必须删除 interface="private" 才能正常工作。
现在的新配置是
<socket-binding name="jgroups-mping" port="0" multicast-address="$jboss.default.multicast.address:230.0.0.201" multicast-port="45700"/>
<socket-binding name="jgroups-tcp" port="7600"/>
<socket-binding name="jgroups-tcp-fd" port="57600"/>
<socket-binding name="jgroups-udp" port="55200" multicast-address="$jboss.default.multicast.address:230.0.0.201" multicast-port="45688"/>
<socket-binding name="jgroups-udp-fd" port="54200"/>
【讨论】：
我尝试了上述使用 Apache HTTPD 服务器作为负载平衡器的集群配置解决方案，您是否尝试过使用 Apache HTTPD 服务器进行集群部署？你能帮我完成以下集群配置吗：***.com/questions/43454068/…以上是关于我无法让会话复制与 Wildfly 10 一起使用的主要内容，如果未能解决你的问题，请参考以下文章
