EC2上的Infinispan和J组发现

Question

我正在尝试在一些带有Tomcat服务器的Linux机器上使用AWS EC2上的应用程序。之前，我在局域网上使用Infinispan应用程序，并使用UDP多播进行JGroups成员发现。EC2不支持UDP多播，这是Infinispan用于检测集群中运行的节点的默认节点发现方法。我研究了使用S3\u-PING协议，但我还没有弄清楚为什么它不起作用。

有人知道问题出在哪里吗？

这是我的配置文件：1. Applicationontext-cache.xml

<!-- Infinispan cache -->
<cache:annotation-driven/>

<import resource="classpath:/applicationContext-dao.xml"/>


<bean id="cacheManager" class="org.infinispan.spring.provider.SpringEmbeddedCacheManagerFactoryBean">
    <property name="configurationFileLocation" value="classpath:/infinispan-replication.xml"/>
</bean>

<context:component-scan base-package="com.alex.cache"/>

2.infinispan-复制。xml

<infinispan xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:schemaLocation="urn:infinispan:config:5.1 http://www.infinispan.org/schemas/infinispan-config-5.1.xsd"
        xmlns="urn:infinispan:config:5.1">

<global>
    <transport transportClass="org.infinispan.remoting.transport.jgroups.JGroupsTransport">
        <properties>
            <property name="configurationFile" value="/home/akasiyanik/dev/projects/myapp/myapp-configs/jgroups.xml"/>
        </properties>
    </transport>
</global>

<default>
    <!-- Configure a synchronous replication cache -->
    <clustering mode="replication">
        <sync/>
        <hash numOwners="2"/>
    </clustering>
</default>
</infinispan>

3、J组。xml

<config>

     />

</config>

使用此选项：https://github.com/meltmedia/jgroups-aws

它是使用AWS API（多播替换）为AWS实现的JGroups发现协议
