JA-SIG（CAS）学习笔记1

实验背景：
系统环境： Windows XP  |  SUN JDK1.6U4 | Tomcat6.0.14 | CAS Server 3.1.1 + CAS Client 2.1.1
主机完整名称： Linly
浏览器： FireFox V2.0.0.11

实验步骤：
STEP 1，搭建Java Web服务器环境
安装 JDK + Tomcat 6.0.14 ， HTTP端口8080 ， HTTPS端口8443
JAVA_HOME = D:\Java\jdk1.6.0_04
CATALINA_HOME = D:\Java\apache-tomcat-6.0.14
安装完毕，启动Tomcat ，在浏览器上 测试 http://Linly:8080/

出现上述界面，表明系统STEP1成功搭建。

STEP 2，使用Java Keytool工具为系统生成HTTPS证书，并为系统注册
（Java Keytool相关资料可参阅：Java keytool 安全证书学习笔记）， 在DOS窗体运行以下指令（建议编写一个BAT批处理文件执行）

cls
rem please set the env JAVA_HOME before run this bat file
rem delete alia tomcat if it is existed
keytool -delete -alias tomcatsso -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit
keytool -delete -alias tomcatsso -storepass changeit
（注释： 清除系统中可能存在的名字为tomcatsso 的同名证书）
rem list all alias in the cacerts
keytool -list -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit
（注释： 列出系统证书仓库中存在证书名称列表）
rem generator a key
keytool -genkey -keyalg RSA -alias tomcatsso -dname "cn=linly" -storepass changeit
（注释：指定使用RSA算法，生成别名为tomcatsso的证书，存贮口令为changeit，证书的DN为"cn=linly" ，这个DN必须同当前主机完整名称一致哦，切记！！！）rem export the key
keytool -export -alias tomcatsso -file %java_home%/jre/lib/security/tomcatsso.crt -storepass changeit
（注释： 从keystore中导出别名为tomcatsso的证书，生成文件tomcatsso.crt）rem import into trust cacerts
keytool -import -alias tomcatsso -file %java_home%/jre/lib/security/tomcatsso.crt -keystore %java_home%/jre/lib/security/cacerts -storepass changeit
（注释：将tomcatsso.crt导入jre的可信任证书仓库。注意，安装JDK是有两个jre目录，一个在jdk底下，一个是独立的jre，这里的目录必须同Tomcat使用的jre目录一致，否则后面Tomcat的HTTPS通讯就找不到证书了）
rem list all alias in the cacerts
keytool -list -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit
（注释：列出jre可信任证书仓库中证书名单，验证先前的导入是否成功，如果导入成功，应该在列表中能找到tomcatsso这个别名，如下图）[/quote]

同时，在D:\Java\jdk1.6.0_04\jre\lib\security目录下能找到“tomcatsso.crt”这个文件；在C:\Documents and Settings\Linly目录下能找到“.keystore”文件。
满足上述条件则STEP2部署完成。

STEP 3，配置Tomcat的HTTPS服务
编辑D:\Java\apache-tomcat-6.0.14\conf下的server.xml文件，在connector的配置位置添加以下的配置：

引用

<Connector protocol="org.apache.coyote.http11.Http11Protocol"
           port="8443" minSpareThreads="5" maxSpareThreads="75"
           enableLookups="true" disableUploadTimeout="true"
           acceptCount="100"  maxThreads="200"
           scheme="https" secure="true" SSLEnabled="true"
           keystoreFile="C:/Documents and Settings/new/.keystore" keystorePass="changeit"
           truststoreFile="D:/Java/jdk1.6.0_04/jre/lib/security/cacerts"
           clientAuth="false" sslProtocol="TLS"/>

启动Tomcat，访问https://linly:8443/，出现以下界面说明HTTPS配置生效：


STEP 4，为HelloWorldExample程序配置CAS过滤器
访问http://linly:8080/examples/servlets/servlet/HelloWorldExample，出现以下界面说明应用正常启动：

编辑D:\Java\apache-tomcat-6.0.14\webapps\examples\WEB-INF下的web.xml文件，添加如下信息：

引用

<filter>
<filter-name>CAS Filter</filter-name>
<filter-class>edu.yale.its.tp.cas.client.filter.CASFilter</filter-class>
<init-param>
  <param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>
  <param-value>https://Linly:8443/cas/login</param-value>
</init-param>
<init-param>
  <param-name>edu.yale.its.tp.cas.client.filter.validateUrl</param-name>
  <param-value>https://Linly:8443/cas/serviceValidate</param-value>
</init-param>
<init-param>
  <param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
  <param-value>Linly:8080</param-value>
</init-param>
</filter>

引用

<filter-mapping>
<filter-name>CAS Filter</filter-name>
<url-pattern>/servlets/servlet/HelloWorldExample</url-pattern>
</filter-mapping>

拷贝casclient.jar文件到目录D:\Java\apache-tomcat-6.0.14\webapps\examples\WEB-INF\lib下。
由于我们使用的是Tomcat6.0.14，因此，还要拷贝commons-logging-1.0.4.jar到该目录下。

STEP 5，部署JA-SIG（CAS）服务器
拷贝cas.war到D:\Java\apache-tomcat-6.0.14\webapps目录下。启动Tomcat，访问网址http://linly:8080/cas/index.jsp,出现以下画面：

输入用户名/密码 ：linly/linly（任意两个相同的字窜），点击“登录”，出现以下画面：

表示CAS服务器配置运行成功。


STEP 6，测试JA-SIG（CAS）部署结果
启动Tomcat。
测试使用浏览器登陆以下网址：http://linly:8080/examples/servlets/servlet/HelloWorldExample，页面将弹出以下认证框，点击“确定”


页面将重定向到JA-SIG的SSO登录认证页面



输入用户名=密码，如：linly/linly，则通过验证，进入应用的入口界面，如下：


细心的用户将发现，此时的URL不再是：
http://linly:8080/examples/servlets/servlet/HelloWorldExample，
URL的尾端带上了一个ticket参数：
http://linly:8080/examples/servlets/servlet/HelloWorldExample?ticket=ST-2-qTcfDrdFb0bWndWgaqZD
到此，JA-SIG（CAS）服务器的初步SSO部署宣告成功。

19 楼 cunsky 2008-10-19  

linliangyi2007 写道

cas配置中必须使用完整的计算机域名，不能使用ip或localhost。

不能使用 localhost吗。我但到大多数资料都是用localhost。用计算机名的话。tomcat里面都得改那些啊

18 楼 macun 2008-09-25  

请问下关于cas的client 3.1.1 的配置，如果配置代理应该如何配置？因为项目中要用到cas。现在我们是这样配置的：
<filter>
<filter-name>CAS Single Sign Out Filter</filter-name>
<filter-class>
org.jasig.cas.client.session.SingleSignOutFilter
</filter-class>
</filter>
<filter>
<filter-name>CAS Authentication Filter</filter-name>
<filter-class>
org.jasig.cas.client.authentication.AuthenticationFilter
</filter-class>
<init-param>
<param-name>casServerLoginUrl</param-name>
<param-value>http://cxn:8080/cas/login</param-value>
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://cxn:8080</param-value>
</init-param>
</filter>
<filter>
<filter-name>CAS HttpServletRequest Wrapper Filter</filter-name>
<filter-class>
org.jasig.cas.client.util.HttpServletRequestWrapperFilter
</filter-class>
</filter>
<filter>
<filter-name>CAS Assertion Thread Local Filter</filter-name>
<filter-class>
org.jasig.cas.client.util.AssertionThreadLocalFilter
</filter-class>
</filter>
<filter>
<filter-name>CAS Validation Filter</filter-name>
<filter-class>
org.jasig.cas.client.validation.Cas20ProxyReceivingTicketValidationFilter
</filter-class>
<init-param>
<param-name>casServerUrlPrefix</param-name>
<param-value>http://cxn:8080/cas</param-value>
</init-param>
<init-param>
<param-name>serverName</param-name>
<param-value>http://cxn:8080</param-value>
</init-param>
<init-param>
<param-name>allowAnyProxy</param-name>
<param-value>true</param-value>
</init-param>
</filter>
但是没有配置代理，即得到pgt，应该怎么配置？
请发到我的邮箱[e-mail]
谢谢！

17 楼 redez 2008-09-23  

cas配置中为什么必须使用完整的计算机域名，而不能使用ip。是在代码里规定的吗？如果是的话是那段代码

16 楼 linliangyi2007 2008-05-28  

cas配置中必须使用完整的计算机域名，不能使用ip或localhost。

15 楼 lsqlister 2008-05-11  

javax.net.ssl.SSLHandshakeException: java.security.cert.CertificateException: No name matching localhost found
是什么原因啊？

14 楼 lsqlister 2008-05-11  

<filter>
<filter-name>CAS Filter</filter-name>
<filter-class>edu.yale.its.tp.cas.client.filter.CASFilter</filter-class>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.loginUrl</param-name>
<param-value>https://Linly:8443/cas/login</param-value>
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.validateUrl</param-name>
<param-value>https://Linly:8443/cas/serviceValidate</param-value>
</init-param>
<init-param>
<param-name>edu.yale.its.tp.cas.client.filter.serverName</param-name>
<param-value>Linly:8080</param-value>
</init-param>
</filter>
里面的Linly变为localhost，出现404错误。

请问：<param-value>Linly:8080</param-value> 具体什么功能啊

13 楼 liuho 2008-05-08  

我觉着在%JAVA_HOME%/中包含空格是导致执行命令是出现路径错误的原因，建议jdk装在不包含空格的路径中或者在%JAVA_HOME%/绝对路径下执行命令

12 楼 flymichael 2008-05-07  

博主，如何在自己的AuthenticationHandler里获得session，也就是说怎么得到request对象？

11 楼 flymichael 2008-04-25  

主机部署casserver,客户端部署在另一台机器上，客户端导入了服务端证书和自己的证书，都部署了SSL，访问时，casserver验证通过，但是客户端页面抛出异常

10 楼 flymichael 2008-04-25  

博主，有个异常请教

javax.net.ssl.SSLHandshakeException:java.security.cert.CertificateException: No subject alternative names present

9 楼 flymichael 2008-04-25  

说明一下，执行的时候需要把%JAVA_HOME%替换成绝对路径

8 楼 flymichael 2008-04-23  

在C:\Program Files\Java\jdk1.6.0_03\jre\lib\security目录下操作可完成

7 楼 flymichael 2008-04-23  

反复手写过，错误依旧，博主是否自己手测过？？？

6 楼 flymichael 2008-04-23  

我发现凡是用到%JAVA_HOME%/jre/lib/security/cacerts这句都报错，不管是哪个指令下的
错误显示如下:
keytool错误：java.lang.RuntimeException:用法错误，Files\Java\jdk1.6.0_03/jre/lib/security/cacerts 不是合法的命令
带下划线部分是%JAVA_HOME%,dos窗口显示部分应属正常，前后斜杠不一致，测试一下错误依旧，郁闷中。。。

5 楼 linliangyi2007 2008-04-21  

楼上的兄弟是不是命令行没打全，或者一半的时候被折行了。

4 楼 flymichael 2008-04-21  

keytool -delete -alias tomcatsso -keystore %JAVA_HOME%/jre/lib/security/cacerts -storepass changeit
这句话报keytool错误，java.lang.RuntimeException运行期错误，
JAVA_HOME%/jre/lib/security/cacerts 不是合法命令

3 楼 linliangyi2007 2008-03-06  

楼上的兄弟看的真细，确实楼掉了过滤器的url配置，真不好意思！
补上了，多谢多谢！

2 楼 猫尾摆摆 2008-03-06  

第四步似乎有问题，按照你的配置，是不会出现网页受保护的提示的，而且也不是通过https连接。

应该加上
<filter-mapping>
<filter-name>CAS Filter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
