弄了一下午的cas安装�l�于成功了，�Q�现在将步骤叙述一�?br />下蝲
cas-server-3.0.4.zip http://www.ja-sig.org/downloads/cas/cas-server-3.0.4.zip

cas-client-2.0.11.zip http://www.ja-sig.org/downloads/cas-clients/cas-client-2.0.11.zip

环境�?winxp tomcat5.5.17 jdk1.5.0_05
1. 生成服务端证�?br />keytool -genkey -alias casserver -keyalg RSA -keystore tomcat.jks
CN�Q�localhost
其他的随便 �?
�q�里要注意姓名必��L��服务器的域名 �׃��我是在本机所以是localhost
如果不这样写��׃��(x��)报如下异常：(x��)
java.io.IOException: HTTPS hostname wrong: should be

�q�个异常出现在创��书的�W�一个问�?姓名。其实这个“姓名”应该是域名。比如说localhost或是blogjava.net之类的。输成了姓名�Q�和真正�q�行的时候域名不�W�，��׃��(x��)出错。浏览器无所谓，弹出一个对话框�Q�用��h��一下就行了。但http client��q��接抛��Z��异常�?-google出来�?br />
2. 导出证书
keytool -export -file cas.cer -alias tomcat -keystore tomcat.jks

3.把导出的证书导入到jre/lib/security的cacerts�?br />�q�里又有一点要注意的 �?可能�׃��我的jre在线升��q�一��?现在的工作的jre目录在C:\Program Files\Java\jre1.5.0_06\ 所以要把证书导入到C:\Program Files\Java\jre1.5.0_06\lib\security的cacerts中去
我一开始就是因�?导入��C��%JAVA_HOME%的jre�?�l�果弄了半天都不成功报异常如下：(x��)
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

4.配置tomcat使用ssl
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" disableUploadTimeout="true"
               acceptCount="100" scheme="https" secure="true"
               clientAuth="false"http://单向SSL
               keystoreFile="C:\tomcat.jks" //我生成的keystore存放在c�?br />               sslProtocol="TLS" />

5. 部��vCAS应用
解压 cas-server-3.0.4.zip, 提取 \target\cas.war 文�g�Q�将 cas.war 文�g复制�?/span> TOMCAT 的安装�\�?/span> webapps 下，启动 TOMCAT �Q�检�?/span> CAS 应用是否正常启动�?br />
6.客户端配�|?br />下蝲cas-client-2.0.11.zip
�?/font> java/lib/casclient.jar考到你所发布的webapp的WEB-INF/lib�?br />修改WEB-INF/web.xml 在里面添加过滤器

        CASFilter
        edu.yale.its.tp.cas.client.filter.CASFilter

           edu.yale.its.tp.cas.client.filter.loginUrl
           https://localhost:8443/cas/login


           edu.yale.its.tp.cas.client.filter.validateUrl
           https://localhost:8443/cas/proxyValidate


          edu.yale.its.tp.cas.client.filter.serverName
          localhost:8443




        CASFilter
        /*


把里面的localhost换成域名
8443换成你所使用的端�?/font>

接着�q�接 https://localhost:8443/app1 //app1是你要实现sso的web应用
接着��面��׃��(x��)跌��{到cas的登陆页�?��像你在�W?步看到的��面一�?
随便用一个用户名登陆只要用户名和密码一样就可以登陆
可以在app2上重复步�? �q�样只要在app1上登陆后再连接app2的url��׃��用再�ơ登陆了
�q�就是单点登陆了�?/font>

其实是一个很��单的事情但是�q�程中要注意步骤1�?
