CAS 与Tomcat 集成

第一节：生成证书

第一步：生成keystore注意【cn=www.xxx.com】这个一般为域名或者地址不同会出现no match dname

  

keytool -genkey -keyalg RSA -alias tomcatmycas -dname "cn=localhost" -storepass 123456 -keystore f:\api\keyserver.keystore

 第二步：导出证书

 

keytool -export -alias tomcatmycas -file D:\Java\jdk1.7.0_71\jre\lib\security\tomcatmycas.crt -storepass 123456 -keystore f:\api\keyserver.keystore

第三步：导入到运行环境中的JDK中【注意：当存在多个jdk时一定要导入到对应的JRE中】

keytool -import -alias tomcatmycas -file D:\Java\jdk1.7.0_71\jre\lib\security\tomcatmycas.crt -keystore D:\Java\JRE\lib\security\cacerts -storepass changeit

 

第二节 Tomcat 的配置

 

第一步：server.xml配置

 

<!--org.apache.coyote.http11.Http11NioProtocol-->
    <Connector port="8443" protocol="org.apache.coyote.http11.Http11Protocol"
               maxThreads="150" SSLEnabled="true" scheme="https" secure="true"
			   keystoreFile="f:\api\keyserver.keystore" keystorePass="123456" 
			   truststoreFile="D:\Java\jdk1.7.0_71\jre\lib\security\cacerts"
			   clientAuth="false" sslProtocol="TLS" />

 

第二步：将cas-server-3.5.2.1-release【cas-server-webapp-3.5.2.1.war】改名为【cas.war】导入项目中

WEB-INF\deployerConfigContext.xml
