CAS 与Tomcat 集成

liyao20060101

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

| attempting to authenticate to CAS /login .  In the default configuration, it is the DefaultCredentialsToPrincipalResolver
| that fills this role.  If you are using some other kind of credentials than UsernamePasswordCredentials, you will need to replace
| DefaultCredentialsToPrincipalResolver with a CredentialsToPrincipalResolver that supports the credentials you are
| using.
|
| Second, AuthenticationManagerImpl uses these resolvers to identify a service requesting a proxy granting ticket.
| In the default configuration, it is the HttpBasedServiceCredentialsToPrincipalResolver that serves this purpose.

　　错误情况：
　　1）CAS unable to find valid certification path 【JDK默认密码为：changeit】

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
　　2) 如果证书已经存在可以删除

keytool -delete -alias tomcatmycas -keystore f:\api\keyserver.keystore -storepass 123456
