1. generate keystore

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

password : 123456

2. setting the tomcat server.xml

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

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

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

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

　　 ~https://localhost:8443/cas

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

1. java jdk不支持以ip建立证书，所以需要虚拟一个域名，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可以删除，这时导入的文件会重新生成该文件， 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.创建cas client工程(web工程)casclient，配置xml文件，并导入相关jar包

<?xml version="1.0" encoding="UTF-8"?>

记得，在tomcat的server.xml中要修改相关port，如果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，可以看到地址栏变了，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 ，不在需要cas server登录，直接看到index.jsp页面

update 2016-10-13 14:41

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，也可以用主机名；

keypass 和 storepass 一致，否则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一样，如果客户端在多台机器上，需要多次导入

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登录

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="" shutdown="SHUTDOWN">

..  

  <Connector port="" protocol="HTTP/1.1"

               connectionTimeout=""

               redirectPort="" />

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登录界面，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就不要登录了。

访问https://demo.cdv.com:8443/cas/logout可以注销登录
