版本

---

tomcat版本: tomcat-8.0.29

jdk版本: jdk1.8.0_65

cas版本: 4.1.3

**cas4.1.3 (4.x还在开发过程中不是很稳定，迭代比较快，也会有些bug) **

cas-client-3.4.1

Ehcache版本: 2.10.1

内容

目标架构

准备

参照下列文章配置好相关环境

• CAS (1) —— Mac下配置CAS到Tomcat（服务端）

• CAS 4.x (7) —— Mac下配置CAS集群及JPATicketRegistry（服务端）

• CAS (8) —— Mac下配置CAS到JBoss EAP 6.4(6.x)的Standalone模式（服务端）

• CAS (10) —— JBoss EAP 6.4下部署CAS时出现错误exception.message=Error decoding flow execution的解决办法

配置

• Ehcache Maven

  • 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" />

              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

• Ehcache在CAS TicketRegistry.xml 中的配置
