目标架构

准备

参照以下文章首先准备好如下图的环境

• CAS (1) —— Mac下配置CAS到Tomcat（服务端
• CAS (2) —— Mac下配置CAS到Tomcat（客户端）
• CAS (3) —— Mac下配置CAS客户端经代理访问Tomcat CAS
• CAS (5) —— Nginx代理模式下浏览器访问CAS服务器配置详解

检查列表

• CAS Client A - app1.hoau.com:8413 (node-a)
• CAS Client B - app2.hoau.com:8423 (node-b)
• CAS Server A - sso.hoau.com:8433 (node-c)
• CAS Server B - sso.hoau.com:8443 (node-d)
• Nginx - Load Balancer

配置

接文章(CAS (5) —— Nginx代理模式下浏览器访问CAS服务器配置详解)之后，我们尝试为CAS
服务配置多个节点。

如若要想实现CAS集群，关于RegistryTicket可以有多种处理方式：

1. Tomcat Session Replication (默认状态下，Ticket信息是存储与Session之中的)
2. 独立的缓存存储方案
   • Memcached
   • Ehcache
   • Redis
3. 数据库存储JpaTicketRegistry

*注意：本篇文章主要关注的是JpaTicketRegistry这种方式再集群环境下的解决方案

当我们实现了用Nginx代理转发到node-c，并成功实现app1.hoau.com与app2.hoau.com的SSO后，以node-c的配置为例，我们配置好node-d，并且打开nginx的Load Balancer和Sticky Session

• nginx.conf

upstream

upstream cas_server_ssl {  
    server sso.hoau.com:8433 weight=1 srun_id=cas-tomcat-c; 
    server sso.hoau.com:8443 weight=1 srun_id=cas-tomcat-d; 
    jvm_route $cookie_JSESSIONID|sessionid reverse;
}  

*注意：以上配置中的jvm_route和srun_id，其中srun_id需要和node-c和node-d中的Catalina server.xml配置一致

server

server { 
    listen 443;
    server_name  proxy.sso.hoau.com;
    ssl on; 
    ssl_certificate /Users/Richard/Documents/Dev/servers/cluster/nginx/keys/server.crt; 
    ssl_certificate_key  /Users/Richard/Documents/Dev/servers/cluster/nginx/keys/server.key; 

    ssl_session_timeout 5m;
    ssl_protocols SSLv3 TLSv1;
    ssl_ciphers ALL:!ADH:!EXPORT56:RC4+RSA:+HIGH:+MEDIUM:+LOW:+SSLv2:+EXP;
    ssl_prefer_server_ciphers on;

    location / {
        #root   html;
        #index  index.html index.htm index.jsp;
        proxy_redirect off;  

        proxy_set_header Host $host;  
        proxy_set_header   Referer $http_referer;
        proxy_set_header   Cookie $http_cookie;
        proxy_set_header X-Real-IP $remote_addr;  
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-FORWARDED-HOST $server_addr;  
        proxy_set_header X-FORWARDED-PORT $server_port;

        proxy_connect_timeout 3;
        proxy_send_timeout 30;
        proxy_read_timeout 30;

        proxy_pass https://cas_server_ssl;
      }
}

如果此时尝试测试系统，可能会出现以下错误，原因是因为两个CAS Server的Session不共享，随机生成的Ticket并不能在两个不同的CAS Server环境下同时使用。

javax.servlet.ServletException: org.jasig.cas.client.validation.TicketValidationException:
	Ticket 'ST-1-9yxMX3RGh9helSCSwNTb-cas01.sso.hoau.com' not recognized

org.jasig.cas.client.validation.AbstractTicketValidatorFilter.doFilter(AbstractTicketValidationFilter.java:227)

*注意: 这是我们尝试配置JpaTicketRegistry的初衷（当然也可以通过上述的多种方式都能解决此问题）

• ticketRegistry.xml

以下是4.1.x官方文档给出来的示例配置，在4.1.x后CAS将以前@Transactional的注解方式更改成了下面推荐的这种aop方式，但是下面的配置对于4.1.2/4.1.3这两个版本缺少了一点东西，运行时可能会遇到错误。

*注意: 如果使用MySQL5.x以上的entityManagerFactory需要修改，这在多数论坛文章中都能找到

<bean id="entityManagerFactory"
      class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
      p:dataSource-ref="ticketDataSource"
      p:jpaVendorAdapter-ref="jpaVendorAdapter"

            <prop key="hibernate.hbm2ddl.auto">update</prop>
        </props>
    </property>
</bean>

这里比较重要的是hibernate.dialect需要根据目标数据库配置，另外hibernate.hbm2ddl.auto是给JPATicketRegistry赋予相应权限的，因为在服务启动时，系统会自动检测目标数据库中，是否含有相应表的信息，如果没有，则会执行ddl脚本创建表：

• locks
• SERVICETICKET
• TICKETGRANTINGTICKET

关于锁的策略（Cleaner Locking Strategy）

4.1.x版本提供了JpaLockingStrategy，来支持exclusive non-reentrant lock

This will configure the cleaner with the following defaults:

tableName = “LOCKS”

uniqueIdColumnName = “UNIQUE_ID”

applicationIdColumnName = “APPLICATION_ID”

expirationDataColumnName = “EXPIRATION_DATE”

platform = SQL92

lockTimeout = 3600 (1 hour)

为了降低死锁出现的概率需要添加以下索引

MySQL

CREATE INDEX ST_TGT_FK_I ON SERVICETICKET (ticketGrantingTicket_ID);
CREATE INDEX ST_TGT_FK_I ON TICKETGRANTINGTICKET (ticketGrantingTicket_ID);

以上这些内容，都能在官方文档中找到，还有其他相关的重要说明，在此不赘述。

*注意: 如果这样配置完毕，然后充其服务器进行测试，会遇到以下错误

org.jasig.cas.web.flow.GenerateServiceTicketAction@7c10e841 in state 'generateServiceTicket' of flow 'login' -- action execution attributes were 'map[[empty]]'] with root cause

错误

*注意: 此处请不要按照错误提示再META-INF下增加persistence.xml文件，否则可能会出现冲突的情况。

• 请用“SimpleTriggerFactoryBean”而非某些论坛里面使用的“org.springframework.scheduling.quartz.SimpleTriggerBean”（这可能是老版本配置），正确配置如下：

    <bean id="periodicTicketRegistryCleanerTrigger"
    	class="org.springframework.scheduling.quartz.SimpleTriggerFactoryBean"
    	p:jobDetail-ref="ticketRegistryCleanerJobDetail"
    	p:startDelay="20000"
    	p:repeatInterval="5000000"  />
  

• 为DefaultTicketRegistryCleaner加上centralAuthenticationService

  老版本的DefaultTicketRegistryCleaner无需centralAuthenticationService，如果4.1.x没有加上这个会出现错误：

    18-Dec-2015 08:55:43.357 SEVERE [localhost-startStop-1] org.apache.catalina.core.StandardContext.listenerStart Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener

  正确配置如下：

    <bean id="ticketRegistryCleaner" class="org.jasig.cas.ticket.registry.support.DefaultTicketRegistryCleaner"
    c:centralAuthenticationService-ref="centralAuthenticationService"
    c:ticketRegistry-ref="ticketRegistry"
    p:lock-ref="cleanerLock"
    />
  

• 请使用较高版本的com.mchange.v2.c3p0
