环境
apache-tomcat-8.5.45
jdk1.8.0_65
cas服务端:5.2.6
cas客户端:cas-sample-java-webapp
一、部署方案
1、网络拓扑
2、组件清单
3、设置hosts
设置PCS101、PCS102、PCS103三台机器的/etc/hosts以及浏览器所在windows主机C:WindowsSystem32driversetchosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 192.168.123.101 PCS101 192.168.123.102 PCS102 192.168.123.103 PCS103 192.168.123.101 cas.example.org 192.168.123.102 app1.PCS102.org 192.168.123.103 app2.PCS103.org
二、CAS服务端和客户端https证书设置
首先参考：
java生成Https证书，及证书导入的步骤和过程
关于几种格式证书的区别
1、CAS服务端https证书设置
(1)生成服务器的密匙文件casserver.keystore
[root@PCS101 bin]# keytool -genkey -alias casserver -keyalg RSA -keysize 2048 -keypass 123456 -storepass 123456 -keystore /root/casserver.keystore -validity 365 -dname "CN=cas.example.org,OU=example.com,O=cas,L=JiNan,ST=JiNan,C=CN" [root@PCS101 bin]# ll /root/casserver.keystore -rw-r--r--. 1 root root 2237 Sep 25 11:42 /root/casserver.keystore #查看密匙文件casserver.keystore命令 [root@PCS101 ~]# keytool -v -list -storepass 123456 -keystore /root/casserver.keystore Keystore type: JKS Keystore provider: SUN Your keystore contains 1 entry Alias name: casserver Creation date: Sep 25, 2020 Entry type: PrivateKeyEntry Certificate chain length: 1 Certificate[1]: Owner: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Issuer: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Serial number: 12cb4c39 Valid from: Fri Sep 25 15:40:49 CST 2020 until: Sat Sep 25 15:40:49 CST 2021 Certificate fingerprints: MD5: B0:39:F9:84:B3:2A:9E:B7:97:8B:A2:E1:36:45:6E:CC SHA1: 29:4A:78:5E:1D:04:D5:35:80:AB:07:9A:50:01:D3:21:E7:4E:F4:2D SHA256: 45:E7:C9:AA:24:CC:87:70:BB:64:40:3B:C7:9B:E0:60:BB:B2:58:76:E6:4F:38:AF:14:44:9B:36:AA:0D:87:A9 Signature algorithm name: SHA256withRSA Version: 3 Extensions: #1: ObjectId: 2.5.29.14 Criticality=false SubjectKeyIdentifier [ KeyIdentifier [ 0000: 02 9A C2 86 BD D9 21 E8 FF 58 7A 0B 2B 82 76 B6 ......!..Xz.+.v. 0010: 2E 84 04 53 ...S ] ] ******************************************* *******************************************
(2)为CAS客户端和浏览器生成证书 casserver.cer
#必须加入-validity 365 否则导入浏览器提示过期 [root@PCS101 bin]# keytool -export -alias casserver -keystore /root/casserver.keystore -file /root/casserver.cer -storepass 123456 -validity 365 Certificate stored in file </root/casserver.cer> [root@PCS101 bin]# ll /root/casserver.cer -rw-r--r--. 1 root root 889 Sep 25 11:43 /root/casserver.cer #打印cer证书内容 [root@PCS101 ~]# keytool -printcert -file /root/casserver.cer Owner: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Issuer: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Serial number: 12cb4c39 Valid from: Fri Sep 25 15:40:49 CST 2020 until: Sat Sep 25 15:40:49 CST 2021 Certificate fingerprints: MD5: B0:39:F9:84:B3:2A:9E:B7:97:8B:A2:E1:36:45:6E:CC SHA1: 29:4A:78:5E:1D:04:D5:35:80:AB:07:9A:50:01:D3:21:E7:4E:F4:2D SHA256: 45:E7:C9:AA:24:CC:87:70:BB:64:40:3B:C7:9B:E0:60:BB:B2:58:76:E6:4F:38:AF:14:44:9B:36:AA:0D:87:A9 Signature algorithm name: SHA256withRSA Version: 3 Extensions: #1: ObjectId: 2.5.29.14 Criticality=false SubjectKeyIdentifier [ KeyIdentifier [ 0000: 02 9A C2 86 BD D9 21 E8 FF 58 7A 0B 2B 82 76 B6 ......!..Xz.+.v. 0010: 2E 84 04 53 ...S ] ]
(3)服务端导入证书文件到cacerts密钥库文件
接下来就是把上面生成的服务器的证书casserver.cer导入到cacerts密钥库文件中(后面的客户端会用到这些)
[root@PCS101 ~]# keytool -import -trustcacerts -alias casserver -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casserver.cer Owner: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Issuer: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Serial number: 12cb4c39 Valid from: Fri Sep 25 15:40:49 CST 2020 until: Sat Sep 25 15:40:49 CST 2021 Certificate fingerprints: MD5: B0:39:F9:84:B3:2A:9E:B7:97:8B:A2:E1:36:45:6E:CC SHA1: 29:4A:78:5E:1D:04:D5:35:80:AB:07:9A:50:01:D3:21:E7:4E:F4:2D SHA256: 45:E7:C9:AA:24:CC:87:70:BB:64:40:3B:C7:9B:E0:60:BB:B2:58:76:E6:4F:38:AF:14:44:9B:36:AA:0D:87:A9 Signature algorithm name: SHA256withRSA Version: 3 Extensions: #1: ObjectId: 2.5.29.14 Criticality=false SubjectKeyIdentifier [ KeyIdentifier [ 0000: 02 9A C2 86 BD D9 21 E8 FF 58 7A 0B 2B 82 76 B6 ......!..Xz.+.v. 0010: 2E 84 04 53 ...S ] ] Trust this certificate? [no]: yes Certificate was added to keystore [root@PCS101 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas casserver, Sep 25, 2020, trustedCertEntry,
(4)CAS服务端tomcat配置server.xml
<Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="/root/casserver.keystore" keystorePass="123456" clientAuth="false" sslProtocol="TLS"/>
(5)浏览器导入证书
谷歌浏览器或者高版本的IE可以导入cer格式证书，而低版本的IE或者firefox浏览器需要导入p12格式证书
未导入证书casserver.cer访问 会提示安全证书警告：
导入证书casserver.cer之后访问：
查看导入证书：
(5.1)cer导入浏览器
谷歌浏览器如何导入证书参考
(5.2)将cer格式的证书转换为p12证书
keytool -importkeystore -srckeystore /root/casserver.keystore -destkeystore /root/casserver.p12 -srcalias casserver -destalias casserverp12 -srcstoretype jks -deststoretype pkcs12 -srcstorepass 123456 -deststorepass 123456 -noprompt
(5.3)直接生成p12证书
#根据密钥keystore生成p12证书： keytool -genkey -v -alias client -keyalg RSA -storetype PKCS12 -keystore /root/casserver.p12 -keypass 123456 -storepass 123456 #将p12证书导出为cer证书(-rfc 指定以Base64编码格式输出)： keytool -export -alias client -storepass 123456 -keystore /root/casserver.p12 -storetype PKCS12 -rfc -file /root/casserver.cer
2、CAS客户端添加CAS服务端授予的证书casserver.cer
(1)生成客户端密钥库文件
单向认证的客户端配置只需生成客户端信任文件caserts即可。
将PCS101-CAS服务端生成的casserver.cer上传到PCS102、PCS103
[root@PCS101 ~]# scp /root/casserver.cer root@PCS102:/root casserver.cer 100% 889 1.0MB/s 00:00 [root@PCS101 ~]# scp /root/casserver.cer root@PCS103:/root casserver.cer 100% 889 1.6MB/s 00:00
(2)PCS102、PCS103导入证书
然后使用命令导入jre，一定要是跑客户端的Tomcat的那个jre，这里是/usr/local/jdk1.8.0_65/jre
[root@PCS102 ~]# keytool -import -trustcacerts -alias casserver -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casserver.cer [root@PCS103 ~]# keytool -import -trustcacerts -alias casserver -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casserver.cer 查看导入的证书清单,密码是changeit [root@PCS102 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas 后期可以删除导入的证书,密码也是changeit [root@PCS102 ~]# keytool -delete -alias casserver -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts [root@PCS102 ~]# keytool -import -trustcacerts -alias casserver -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casserver.cer Owner: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Issuer: CN=cas.example.org, OU=example.com, O=cas, L=JiNan, ST=JiNan, C=CN Serial number: 12cb4c39 Valid from: Fri Sep 25 15:40:49 CST 2020 until: Sat Sep 25 15:40:49 CST 2021 Certificate fingerprints: MD5: B0:39:F9:84:B3:2A:9E:B7:97:8B:A2:E1:36:45:6E:CC SHA1: 29:4A:78:5E:1D:04:D5:35:80:AB:07:9A:50:01:D3:21:E7:4E:F4:2D SHA256: 45:E7:C9:AA:24:CC:87:70:BB:64:40:3B:C7:9B:E0:60:BB:B2:58:76:E6:4F:38:AF:14:44:9B:36:AA:0D:87:A9 Signature algorithm name: SHA256withRSA Version: 3 Extensions: #1: ObjectId: 2.5.29.14 Criticality=false SubjectKeyIdentifier [ KeyIdentifier [ 0000: 02 9A C2 86 BD D9 21 E8 FF 58 7A 0B 2B 82 76 B6 ......!..Xz.+.v. 0010: 2E 84 04 53 ...S ] ] Trust this certificate? [no]: yes Certificate was added to keystore [root@PCS102 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas casserver, Sep 25, 2020, trustedCertEntry,
3、CAS客户端证书 用来给浏览器的证书
(1)生成服务器的密匙文件
#PCS102:casclient1.keystore [root@PCS102 ~]# keytool -genkey -alias casclient1 -keyalg RSA -keysize 2048 -keypass 123456 -storepass 123456 -keystore /root/casclient1.keystore -validity 365 -dname "CN=app1.PCS102.org,OU=PCS102.com,O=cas,L=JiNan,ST=JiNan,C=CN" #PCS103:casclient2.keystore [root@PCS103 ~]# keytool -genkey -alias casclient2 -keyalg RSA -keysize 2048 -keypass 123456 -storepass 123456 -keystore /root/casclient2.keystore -validity 365 -dname "CN=app2.PCS103.org,OU=PCS103.com,O=cas,L=JiNan,ST=JiNan,C=CN"
(2)生成证书casserver.cer
#PCS102:casclient1.cer [root@PCS102 ~]# keytool -export -alias casclient1 -keystore /root/casclient1.keystore -file /root/casclient1.cer -storepass 123456 -validity 365 #PCS102:casclient2.cer [root@PCS103 ~]# keytool -export -alias casclient2 -keystore /root/casclient2.keystore -file /root/casclient2.cer -storepass 123456 -validity 365
(3)客户端将证书文件导入到密钥库文件cacerts
#PCS102:cacerts [root@PCS102 ~]# keytool -import -trustcacerts -alias casclient1 -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casclient1.cer #PCS103:cacerts [root@PCS103 ~]# keytool -import -trustcacerts -alias casclient2 -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts -file /root/casclient2.cer
最终各主机cer信任清单:
[root@PCS101 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas casserver, Sep 25, 2020, trustedCertEntry, [root@PCS102 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas casserver, Sep 25, 2020, trustedCertEntry, casclient1, Sep 25, 2020, trustedCertEntry, [root@PCS103 ~]# keytool -list -storepass changeit -keystore /usr/local/jdk1.8.0_65/jre/lib/security/cacerts |grep cas casserver, Sep 25, 2020, trustedCertEntry, casclient2, Sep 25, 2020, trustedCertEntry,
(4)修改PCS102、PCS103三台机器的Tomcat的server.xml，启用https
PCS102： <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="/root/casclient1.keystore" keystorePass="123456" clientAuth="false" <!--false表示单向认证 true表示双向认证--> sslProtocol="TLS"/> PCS103： <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="/root/casclient2.keystore" keystorePass="123456" clientAuth="false" <!--false表示单向认证 true表示双向认证--> sslProtocol="TLS"/>
clientAuth:设置是否双向验证，默认为false，设置为true代表双向验证 设置clientAuth属性为True时，需要手动导入客户端证书才能访问。
(5)浏览器导入casclient1.cer和casclient1.cer证书
二、部署cas服务端
三、准备cas客户端
1、下载
从官网客户端cas-sample-java-webapp
Administrator@PC-20190528ODKR MINGW64 /e/cas/cas-sample-java-webapp (master) $ git clone https://github.com/cas-projects/cas-sample-java-webapp.git
2、导入idea
cas-sample-java-webapp内置了jetty,我这里导入idea制作war包,然后用tomcat运行。
cas-sample-java-webapp1:
(1)调整pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>iamlabs.unicon.net</groupId> <artifactId>cas-sample-java-webapp</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>war</packaging> <name>CAS Example Java Web App</name> <description>A sample web application that exercises the CAS protocol features via the Java CAS Client.</description> <build> <finalName>cas-sample-java-webapp</finalName> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.5.1</version> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> <!-- <plugin> <groupId>org.eclipse.jetty</groupId> <artifactId>jetty-maven-plugin</artifactId> <version>9.3.6.v20151106</version> <configuration> <jettyXml>${basedir}/etc/jetty/jetty.xml,${basedir}/etc/jetty/jetty-ssl.xml,${basedir}/etc/jetty/jetty-https.xml</jettyXml> <systemProperties> <systemProperty> <name>org.eclipse.jetty.annotations.maxWait</name> <value>300</value> </systemProperty> </systemProperties> <webApp> <contextPath>/sample</contextPath> <overrideDescriptor>${basedir}/etc/jetty/web.xml</overrideDescriptor> </webApp> <jvmArgs>-Xdebug -Xrunjdwp:transport=dt_socket,address=5002,server=y,suspend=n</jvmArgs> </configuration> </plugin> --> </plugins> </build> <dependencies> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.jasig.cas.client</groupId> <artifactId>cas-client-core</artifactId> <version>3.4.1</version> <exclusions> <exclusion> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> </exclusion> </exclusions> </dependency> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1.1</version> </dependency> </dependencies> </project>
(2)调整web.xml

(3)构建生成cas-sample-java-webapp.war
四、浏览器访问验证
分别启动PCS101、PCS102、PCS103三台机器上的tomcat。
场景一：
浏览器访问客户端应用：cas-sample-java-webapp1，未登录。
https://app1.PCS102.org:8443/cas-sample-java-webapp/
直接跳转到服务端登录页：
查看F12请求记录：浏览器地址302跳转 https://cas.example.org:8443/cas
登录成功后跳转到app1的index.jsp页面
查看app1的session:
场景二：
浏览器访问客户端应用：cas-sample-java-webapp2，已登录。
https://app2.PCS103.org:8443/cas-sample-java-webapp/
场景三：
浏览器从客户端应用：cas-sample-java-webapp2，点击注销，然后再次访问客户端应用：cas-sample-java-webapp1。
https://app1.PCS102.org:8443/cas-sample-java-webapp/
从app2注销：
再次登录app1，会跳转到CAS服务端登录页面。
