    1，安全证书配置

    CAS默认使用HTTPS协议，如果对安全要求不高，可使用HTTP协议。

    修改为HTTP协议的步骤如下：

    修改deployerConfigContext.xml 增加参数p:requireSecure="false"，意为：不需要安全验证。

     

    [html] view plain copy

    1. <bean class="org.jasig.cas.authentication.handler.support.HttpBasedServiceCredentialsAuthenticationHandler"p:httpClient-ref="httpClient"  
    2. p:requireSecure="false"/>  

    修改 ticketGrantingTicketCookieGenerator.xml (路径：cas/WEB-INF/spring-configuration/ticketGrantingTicketCookieGenerator.xml)中ticketGrantingTicketCookieGeneratorp:cookieSecure 属性的值改为 false。

    1. <bean id="ticketGrantingTicketCookieGenerator"class="org.jasig.cas.web.support.CookieRetrievingCookieGenerator"  
    2. p:cookieSecure="false"p:cookieMaxAge="-1" p:cookieName="CASTGC"p:cookiePath="/cas" />  

    2，部署服务端CAS-Server

    CAS-Server下载地址：http://www.jasig.org/cas/download

    解压cas-server-3.4.11-release.zip提取cas-server-3.4.11/modules/cas-server-webapp-3.4.11.war文件，把改文件copy到Tomcat下，如,D: omacat-casServerwebapps目下，并重命名为：cas.war.

    启动tomacat-casServer，在浏览器地址栏输入：http://localhost:8080/cas/login ，回车

    CAS-server的默认验证规则：只要用户名和密码相同就认证通过（仅仅用于测试，生成环境需要根据实际情况修改），输入admin/admin点击登录，就可以看到登录成功的页面：

    CAS-Server部署成功。

    3,部署CAS-Client

    CAS-Client下载地址：http://downloads.jasig.org/cas-clients/

    (1)解压cas-client-3.2.1-release.zip提取cas-client-3.2.1/modules/cas-client-core-3.2.1.jar

    (2)以tomcat默认自带的 webappsexamples项目作为客户端 

    (3)安装配置 tomcat-client1

    解压apache-tomcat-7.0.6并重命名为tomcat-client1

    ，修改tomcat的启动端口（共计5处），在文件conf/server.xml文件找到如下内容：

     

    [html] view plain copy
     
     在CODE上查看代码片派生到我的代码片
    1. <Server port="8005" shutdown="SHUTDOWN">  
    2. <Connector port="8080" protocol="HTTP/1.1"  
    3.   connectionTimeout="20000"  
    4.   redirectPort="8443" />  
    5. <Connector port="8009" protocol="AJP/1.3"redirectPort="8443" />  

    修改成如下：

     

    [html] view plain copy
     
     在CODE上查看代码片派生到我的代码片
    1. <Server port="18005" shutdown="SHUTDOWN">  
    2. <Connector port="18080" protocol="HTTP/1.1"  
    3.   connectionTimeout="20000"  
    4.   redirectPort="18443" />  
    5. <Connector port="18009" protocol="AJP/1.3"redirectPort="18443" />  

    (4)启动tomcat-app1，浏览器输入http://localhost:18080/examples/servlets/回车：

    tomcat-client的配置成功。

    (5)复制 client的lib包cas-client-core-3.2.1.jar和commons-logging-1.1.jar到tomcat-clientwebappsexamplesWEB-INFlib目录下，在tomcat-clientwebappsexamplesWEB-INFweb.xml 文件中添加如下配置：

    (6)

    安装配置 tomcat-client2

    解压apache-tomcat-7.0.6并重命名为tomcat-client2

    ，修改tomcat的启动端口（共计5处），在文件conf/server.xml文件找到如下内容：

     

    [html] view plain copy
     
     在CODE上查看代码片派生到我的代码片
    1. <Server port="8005" shutdown="SHUTDOWN">  
    2. <Connector port="8080" protocol="HTTP/1.1"  
    3.   connectionTimeout="20000"  
    4.   redirectPort="8443" />  
    5. <Connector port="8009" protocol="AJP/1.3"redirectPort="8443" />  

     

    修改成如下：

     

    [html] view plain copy
     
     在CODE上查看代码片派生到我的代码片
    1. <Server port="28005" shutdown="SHUTDOWN">  
    2. <Connector port="28080" protocol="HTTP/1.1"  
    3.   connectionTimeout="20000"  
    4.   redirectPort="28443" />  
    5. <Connector port="28009" protocol="AJP/1.3"redirectPort="28443" />  

    以下其他步骤同配置tomcat-client1

    4，测试SSO

    分别启动tomcat-casServer、tomcat-client1、tomcat-client2

     

    测试流程：打开client1 url —->跳转cas server 验证 —->显示client1 的应用 —->打开client2 url —-> 显示client2应用 —->注销cas server —->打开client1/client2 url—->重新跳转到cas server验证.

     

    动手操作，观察单点登录效果。
