1. generate keystorehtml

   command : keytool -genkey -alias testtomcat -keyalg RSA -keystore "C:\Users\rocky\testsso\testtomcat.keystore"java

   password : 123456web

  

2. setting the tomcat server.xmlwindows

  

  

 

 3. download and extract cas-server-4.0.0-release.zip浏览器

     ~you can find cas-server-webapp-4.0.0.war in the modules package.tomcat

     ~copy it to tomcat webapps package and rename to cas.war.安全

     ~execute the  startup.bat command as the administrator user.session

　　 ~https://localhost:8443/casapp

    ~login with user( username : casuser; password : Mellon)webapp

1. java jdk不支持以ip创建证书，因此须要虚拟一个域名，如cas.server.com

2. 生成证书

keytool -genkeypair -keyalg RSA -keysize 2048 -sigalg SHA1withRSA -validity 36500 -alias cas.server.com -keystore C:/Users/rocky/testsso/tomcat.keystore -dname "CN=cas.server.com,OU=cdv,O=cdv,L=bj,ST=bj,C=CN"

3. 导出证书

keytool -exportcert -alias cas.server.com -keystore C:/Users/rocky/testsso/tomcat.keystore  -file C:/Users/rocky/testsso/tomcat.cer -rfc

4. tomcat 配置 cas， 浏览器添加证书

  （区别于上面绝对路径方式引用， 现采用相对路径方式）将生成的tomcat.keystore 拷贝到tomcat目录下。

将第三步导出的tomcat.crt 导入到浏览器

 

5.  将tomcat.crt拷贝到cas client所在的机器， 并导入到jdk中（C:\Program Files\Java\jdk1.7.0_15\jre\lib\security\cacerts能够删除，这时导入的文件会从新生成该文件， C:\Program Files\Java\jre7\lib\security该路径下也有cacerts文件，可一并覆盖）

keytool -import -alias cacerts -keystore cacerts -file C:/Users/rocky/testsso/tomcat.cer -trustcacerts

 

6.建立cas client工程(web工程)casclient，配置xml文件，并导入相关jar包

记得，在tomcat的server.xml中要修改相关port，若是在同一台机器上实验，开多个tomcat，也应修改相关port，防止port冲突。

 7.  浏览器输入http://cas.server.com:8081/ssoclient/index.jsp， 能够看到地址栏变了，进入cas server的login页面，输出对的username 和 password， 会跳回到client的index.jsp页面。

     http://cas.server.com:8082/ssoclient2/index.jsp  ，不在须要cas server登陆， 直接看到index.jsp页面

1.演示环境

  windows7 64 主机名：rocky-PC

  JDK : jdk1.7.0_80

  tomcat : tomcat-7.0.70

  cas-server-4.0.0

  cas-client-3.3.3

  windows hosts 文件 添加域名映射  （C:\Windows\System32\drivers\etc）

demo.cdv.com 对应部署的tomcat-cas， 这个名称在生成证书时用到

app1.cdv.com 对应部署的tomcat-app1,  

app2.cdv.com 对应部署的tomcat-app2

 

2. 安全证书配置

 2.1 证书生成

 

   输入的名称和hosts文件一致，也能够用主机名；

  keypass 和 storepass 一致，不然tomcat访问https失败

2.2 导出证书

 

 

2.3 客户端 导入证书

此处导入的密码和上面的不同，若是客户端在多台机器上，须要屡次导入

 

3. cas server部署

3.1 修改 tomcat-cas server.xml

3.2 启动 tomcat-cas， 访问https://demo.cdv.com:8443 并添加 浏览器 访问例外

3.3 从cas-server-4.0.0-> modules下拷贝cas-server-webapp.war到tomcat-cas webapp下 并重命名cas.war

     启动tomcat-cas 访问https://demo.cdv.com:8443/cas/login

     用户名 casuser 密码 Mellon登陆

    看到 Log in successful则cas server部署成功

 

4. cas client部署

  4.1 tomcat-app1

    4.1.1修改server.xml

..
<Server port="18005" shutdown="SHUTDOWN">
..  

  <Connector port="18080" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="18443" />

访问http://app1.cdv.com:18080/examples/servlets/测试端口是否可用

     4.1.2  导入jar

     4.1.3  修改web.xml

5. 测试

 5.1 启动 tomcat-cas , tomcat-app1, tomcat-app2

 5.2 访问 http://app1.cdv.com:18080/examples/servlets/servlet/HelloWorldExample

      跳转到 cas-server登陆界面， 输入用户名+密码 正确， 跳转到helloworld页面；

     访问 http://app2.cdv.com:28080/examples/servlets/servlet/HelloWorldExample就不要登陆了。

     访问https://demo.cdv.com:8443/cas/logout能够注销登陆
