1.编译cas
下载 cas-4.1.9.tar.gz
tar -xzf cas-4.1.9.tar.gz
cd cas-4.1.9
mvn clean install -DskipTests
2.cd cas-server-webapp/target/cas.war ../server-tomcat-8.0.12/webapps/
启动tomcat
通过浏览器访问https://server.hacker.org:8443/cas
用户名和密码在cas\WEB-INF\deployerConfigContext.xml文件中定义
<entry key="casuser" value="Mellon"/>
3.客户端tomcat 配置
两个tomcat-8.0.12\webapps\examples\WEB-INF\lib下添加cas-client-core-3.2.0.jar、commons-logging-1.1.3.jar、slf4j-api-1.7.12.jar三个jar包
修改login-tomcat-8.0.12\webapps\examples\WEB-INF\web.xml
添加

启动login和blog tomcat
4.访问，见证奇迹的时候到了
访问
https://login.hacker.org:18443/examples/servlets/servlet/HelloWorldExample
输入用户名和密码
再访问
https://blog.hacker.org:28443/examples/servlets/servlet/HelloWorldExample
发现不用输入用户名和密码就可以登录
退出登录
https://server.hacker.org:8443/cas/logout
再次访问
https://login.hacker.org:18443/examples/servlets/servlet/HelloWorldExample
发现又要登录
