【CAS学习之二】部署CAS服务端

环境
  apache-tomcat-8.5.45
  cas:5.2.6

一、部署CAS
1、部署war包
将上一篇文章中构建生成的cas.war放到tomcat/webapps下
2、启动tomcat并访问 (官方的基础版本中配置了一个用户 casuser/Mellon)
2.1 CAS项目要求用https连接,如果使用http也行,也能登录成功,只是会提示不安全
访问连接:http://localhost:8080/cas

2.2 去除HTTPS
(1)修改WEB-INF/classess/application.properties,添加以下配置

#去除https验证
cas.tgc.secure=false
#注册Services中的JSON验证
cas.serviceRegistry.initFromJson=true

(2)修改WEB-INF/classess/services/HTTPSandIMAPS-10000001.json
注册哪些客户端可以访问认证中心

{
  "@class" : "org.apereo.cas.services.RegexRegisteredService",
  "serviceId" : "^(https|imaps|http)://.*",
  "name" : "HTTPS and IMAPS",
  "id" : 10000001,
  "description" : "This service definition authorizes all application urls that support HTTPS and IMAPS protocols.",
  "evaluationOrder" : 10000
  "proxyPolicy" : {
    "@class" : "org.jasig.cas.services.RegexMatchingRegisteredServiceProxyPolicy",
    "pattern" : "^(https|imaps|http)://.*"
  }
}

(3)如果客户端之前做过https配置,需要从客户端jre的证书仓库中删掉之前为做HTTPS单点登录加的那个证书

keytool -delete -alias cas -keystore  C:/Java/jdk1.8.0_91/jre/lib/security/cacerts

参考:去除HTTPS   和  配置使用HTTP协议访问的服务端  

2.3 使用https连接,需要先生成https的加密密匙,用jdk自带的keytool就行。

(1)使用jdk生成https证书
JDK中keytool是一个证书管理工具,可以生成自签名证书。 就是自己生成的证书,并不是官方生成的证书。除非是很正式的项目,否则使用自己签发的证书即可,因为官方生成证书是要花钱滴
命令解释

keytool 
-genkey 
-alias cas(别名) 
-keypass 123456(别名密码) 
-keyalg RSA(生证书的算法名称,RSA是一种非对称加密算法) 
-keysize 1024(密钥长度,证书大小) 
-validity 365(证书有效期,天单位) 
-keystore E:/cas/keystore/cas.keystore(指定生成证书的位置和证书名称) 
-storepass 123456(获取keystore信息的密码)
- storetype (指定密钥仓库类型) 
-dname 
"CN=cas.example.org,(您的名字与姓氏是什么?)
OU=example.com,(您的组织单位名称是什么?)
O=cas,(您的组织名称是什么?)
L=Shenzhen,(您所在的城市或区域名称是什么?)
ST=Shenzhen,(您所在的省/市/自治区名称是什么?)
C=CN"(该单位的双字母国家/地区代码是什么?)

进入jdk的bin目录下面,打开CMD命令行工具,执行命令:

keytool -genkey -alias cas -keyalg RSA -keysize 2048 -keypass 123456 -storepass 123456 -keystore E:/cas/keystore/cas.keystore -dname "CN=cas.example.org,OU=example.com,O=cas,L=Jinan,ST=Jinan,C=CN"

关于jdk证书,请参考:

使用JDK自带工具keytool生成ssl证书

(2)同时需要修改 tomcat 的配置文件 server.xml,把加密密匙的相关配置写进去。

    <!-- 去掉 http 访问 8080 端口 -->
  <!-- <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
--> <!-- 用 https 访问 8443 端口 --> <Connector port="8443" protocol="org.apache.coyote.http11.Http11NioProtocol" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="E:/cas/keystore/cas.keystore" keystorePass="123456" clientAuth="false" sslProtocol="TLS"/>

修改完成后 重启Tomcat

(3)访问,用户 casuser/Mellon
访问连接:https://localhost:8443/cas

 

二、改用数据库验证用户名和密码
先来搞清楚application.properties配置文件中各个属性含义,请参考:application.properties

0、本地搭建一个mysql,创建一个数据库castest,新建一个表:cms_auth_user


1、我们这里要拷贝cas.war解压出来的一份cas\WEB-INF\classes\application.properties放到cas-overlay-template\src\main\resources\application.properties,然后作如下修改

##
# CAS Server Context Configuration
#
server.context-path=/cas
server.port=8443
# 这些放在services目录的json文件来注册服务了,
# 先说一下这里的“服务” 其实指的就是客户端,更准确的说就是它的url,如果一个客户端没有注册到CAS的服务列表,
# 那么你通过客户端跳转到CAS,CAS会拒绝这个跳转。
# war包解压出来的services里已经有了两个json文件,其中HTTPSandIMAPS-100xxxxxx.json中有一段:
# "serviceId" : "^(https|imaps|http)://.*",
# 后边这部分是个正则表达式,为了支持http协议的客户端,我在里面加了个http,代表所有URL符合这个正则表达式的服务都会被当成已经注册的服务
cas.serviceRegistry.initFromJson=true

#STEP 签发证书,如果是用spring boot之类嵌入式的容器,则需要改这里的配置,如果是直接部在tomcat中,则需要把tomcat改成https的
#server.ssl.key-store=file:/etc/cas/thekeystore
#server.ssl.key-store-password=changeit
#server.ssl.key-password=changeit
# server.ssl.ciphers=

##
# CAS Thymeleaf View Configuration

#这个配置没有在官网找到说明,是自己摸索出来的,服务端的HTML页面使用的是thymeleaf编写(http://www.ultraq.net.nz/thymeleaf/layout)
#thymeleaf默认会在启动的时候就把页面的静态内容给放到缓存里,这给我修改CAS默认登录页带来了很大的麻烦,每次修改一点点页面内容,刷新是看不到效果的,只得重启服务,为了方便开发,
#我把这个配置设成false,就是说不要缓存。
#
#如果你也想修改登录页这里给出几个建议:
#1、如果不懂thyeleaf先简单了解一下thymeleaf官网的demo写法;
#2、登录页的模板是layout.html,其中有几个js是从谷歌CDN上下载的,而谷歌我们国内又访问不了,
#这就会导致登录页加载非常慢,建议先把这几个js本地化;
#3、登录页主要是casLoginView.html和fragments目录下的loginform.html;
#4、layout.html引入了好几个类似logo.html,footer.html的页面,这几个页面看名字就知道干什么的,建议对他们进行修改,改成自己的

3、重新打包部署  然后登录认证

(1)打开新的登录页面不再提示:不安全连接和固定用户警告

(2)使用原先默认的casuser登录提示:认证信息无效

(3)使用数据库表里配置的用户和密码登录

(4)注销用户
