节点b（以端口8443为例）
<cacheManagerPeerProviderFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual,rmiUrls=//127.0.0.1:41031/cas_st|//127.0.0.1:41031/cas_tgt" />
<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"
properties="port=41041,remoteObjectPort=41042" />
注意以上ProviderFactory和ListenerFactory中的给出的端口：
ListenerFactory是指定本地Cache节点的端口
ProviderFactory是配置远程Cache节点的端口
如果二个以上节点，则所有节点都要列出并用 | 符号分隔
