cas单点登录-服务端部署

news2024/12/30 3:51:03

一.需求描述

公司开发系统越来越多，每个系统都有自己的登录认证流程，给用户很繁琐的体验，统一认证单点登录迫在眉睫

二.流程图

三.本地运行cas服务端

1.拉取cas服务端代码，切换到对应分支（我使用的是6.4.x）

https://github.com/apereo/cas-overlay-template

2.由于6.4版本默认jdk11以上，所以在idea进行如下配置

3.在build.gradle文件加入mysql、jdbc依赖配置，并下载依赖

implementation "org.apereo.cas:cas-server-support-json-service-registry:${project.'cas.version'}"
implementation "org.apereo.cas:cas-server-support-jdbc:${project.'cas.version'}"
implementation "org.apereo.cas:cas-server-support-jdbc-drivers:${project.'cas.version'}"
implementation "mysql:mysql-connector-java:5.1.46"

4.yml配置数据源以及http请求支持

cas:
  authn:
    jdbc:
      query[0]:
        sql: SELECT * FROM user WHERE username = ?
        url: jdbc:mysql://xxxxxx:3306/cas?useUnicode=true&characterEncoding=utf8&useSSL=false
        user: root
        password: xxxx
        fieldPassword: password
        driverClass: com.mysql.jdbc.Driver
        password-encoder:
          type: DEFAULT
          encoding-algorithm: MD5
          character-encoding: UTF-8
        fieldExpired: expired #是否提示改密码的字段
        fieldDisabled: disabled #是否禁用用户的字段
    accept:
      enabled: false
  tgc:
    secure: false
  service-registry:
    core:
      init-from-json: true
    json:
      location: file:/etc/cas/services
#cas.authn.accept 指定的就是默认登录用户casuser, 密码Mellon，enabled设为false，则默认用户便不能登录
#如果 cas.authn.jdbc.query[0].password-encoder.type设为NONE，则不适用密码加密，数据库中需存明文密码

5.在jdk的bin目录生成证书thekeystore

keytool -genkeypair（keytool -genkeypair）来生成对应的keystore

6.在项目对应的盘根目录创建对应子目录（etc/cas/service）,把证书和json文件放进对应的位置

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

7.mysql创建数据库和对应的表，并插入数据

CREATE TABLE `cas` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) DEFAULT NULL COMMENT '用户名',
  `password` varchar(255) DEFAULT NULL COMMENT '密码',
  `create_time` datetime DEFAULT NULL COMMENT '创建时间',
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=2 DEFAULT CHARSET=utf8;

由于cas对密码经过md5加密的，所以密码需要处理后再插入

8.运行启动cas

四. docker-compose部署cas服务

1. 将项目上传到linux服务器，通过命令生成对应的镜像

docker build -t cas.tar:6.4 .

2.编写docker-compose.yml

version: "3"
services:
  cas:
    image: cas:6.4
    container_name: cas-server
    restart: always
    ports:
      - 8083:8080
      - 8443:8443
    volumes:
      - ./conf/cas.properties:/etc/cas/config/cas.properties:ro
      - ./conf/thekeystore:/etc/cas/thekeystore:ro
      - ./conf/HTTPSandHTTP-10000001.json:/etc/cas/services/HTTPSandHTTP-10000001.json:ro

3.编写cas.properties

as.server.name=https://自己的域名:8443
cas.server.prefix=${cas.server.name}/cas

logging.config=file:/etc/cas/config/log4j2.xml

cas.tgc.secure=false
cas.serviceRegistry.initFromJson=true
cas.serviceRegistry.json.location=file:/etc/cas/services

4.启动并访问
