# 第一 生成keystore文件 #

keytool -genkey -v -alias tomcat -keyalg RSA -keystore /Users/java0904/tomcat.keystore

其中`/Users/java0904/tomcat.keystore`是保存的地址  
顺利的话应该提示(我这里设置的密码口令是123456，后面会多次用到)

java0904@weigongdeMacBook-Pro ~ % keytool -genkey -v -alias tomcat -keyalg RSA -keystore /Users/java0904/tomcat.keystore
    
    输入密钥库口令:  
    再次输入新口令: 
    您的名字与姓氏是什么?
      [Unknown]:  java.cas.juhe.cn
    您的组织单位名称是什么?
      [Unknown]:  java.cas.juhe.cn
    您的组织名称是什么?
      [Unknown]:  java.cas.juhe.cn
    您所在的城市或区域名称是什么?
      [Unknown]:  suzhou
    您所在的省/市/自治区名称是什么?
      [Unknown]:  jiangsu
    该单位的双字母国家/地区代码是什么?
      [Unknown]:  cn
    CN=java.cas.juhe.cn, OU=java.cas.juhe.cn, O=java.cas.juhe.cn, L=suzhou, ST=jiangsu, C=cn是否正确?
      [否]:  y
    
    正在为以下对象生成 2,048 位RSA密钥对和自签名证书 (SHA256withRSA) (有效期为 90 天):
    	 CN=java.cas.juhe.cn, OU=java.cas.juhe.cn, O=java.cas.juhe.cn, L=suzhou, ST=jiangsu, C=cn
    输入 <tomcat> 的密钥口令
    	(如果和密钥库口令相同, 按回车):  
    [正在存储/Users/java0904/tomcat.keystore]
    
    Warning:
    JKS 密钥库使用专用格式。建议使用 "keytool -importkeystore -srckeystore /Users/java0904/tomcat.keystore -destkeystore /Users/java0904/tomcat.keystore -deststoretype pkcs12" 迁移到行业标准格式 PKCS12。
    java0904@weigongdeMacBook-Pro ~ % keytool -importkeystore -srckeystore /Users/java0904/tomcat.keystore -destkeystore /Users/java0904/tomcat.keystore -deststoretype pkcs12
    输入源密钥库口令:  
    已成功导入别名 tomcat 的条目。
    已完成导入命令: 1 个条目成功导入, 0 个条目失败或取消
    
    Warning:
    已将 "/Users/java0904/tomcat.keystore" 迁移到 Non JKS/JCEKS。将 JKS 密钥库作为 "/Users/java0904/tomcat.keystore.old" 进行了备份。
    java0904@weigongdeMacBook-Pro ~ %

### 此时在文件夹下面将会生成两个文件，如下所示 ###

-rw-r--r--    1 java0904  staff       2631  3  4 16:39 tomcat.keystore
    -rw-r--r--    1 java0904  staff       2288  3  4 16:39 tomcat.keystore.old

# 第二 生成cer文件，即在本地生成证书 #

keytool -export -trustcacerts -alias tomcat -file /Users/java0904/tomcat.cer -keystore /Users/java0904/tomcat.keystore

顺利的话应该提示

# 第三 将生成的证书导入到jdk中 #

sudo keytool -import -trustcacerts -alias tomcat -file /Users/java0904/tomcat.cer -keystore "/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre/lib/security/cacerts" -storepass changeit

如果你之前导入过这个别名，那么会提示你

java0904@weigongdeMacBook-Pro ~ % keytool -export -trustcacerts -alias tomcat -file /Users/java0904/tomcat.cer -keystore /Users/java0904/tomcat.keystore
    输入密钥库口令:  
    存储在文件 </Users/java0904/tomcat.cer> 中的证书
    java0904@weigongdeMacBook-Pro ~ % sudo keytool -import -trustcacerts -alias tomcat -file /Users/java0904/tomcat.cer -keystore "/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre/lib/security/cacerts"
    Password:
    Sorry, try again.
    Password:
    输入密钥库口令:  
    keytool 错误: java.lang.Exception: 证书未导入, 别名 <tomcat> 已经存在

此时可以用如下命令查看已经存在的证书

sudo keytool -list -file /Users/java0904/tomcat.cer -keystore "/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre/lib/security/cacerts" -storepass changeit

此时我需要删除已经存在的，重新覆盖，可以用如下命令删除

sudo keytool -delete -alias tomcat -file /Users/java0904/tomcat.cer -keystore "/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre/lib/security/cacerts" -storepass changeit

正确的话，应该会提示

java0904@weigongdeMacBook-Pro ~ % sudo keytool -import -trustcacerts -alias tomcat -file /Users/java0904/tomcat.cer -keystore "/Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home/jre/lib/security/cacerts" -storepass changeit

# 第四，配置tomcat #

在conf/server.xml文件中加入

# 第五，启动cas-server服务 #

下载cas-server服务，大家可以网上搜一下cas-server war包，把这个war包放到tomcat下的webapp目录

# 第六，启动tomcat #

java0904@weigongdeMacBook-Pro bin % pwd
    /Users/java0904/Downloads/apache-tomcat-9.0.30/bin
    java0904@weigongdeMacBook-Pro bin % 
    java0904@weigongdeMacBook-Pro bin % ./startup.sh 
    Using CATALINA_BASE:   /Users/java0904/Downloads/apache-tomcat-9.0.30
    Using CATALINA_HOME:   /Users/java0904/Downloads/apache-tomcat-9.0.30
    Using CATALINA_TMPDIR: /Users/java0904/Downloads/apache-tomcat-9.0.30/temp
    Using JRE_HOME:        /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
    Using CLASSPATH:       /Users/java0904/Downloads/apache-tomcat-9.0.30/bin/bootstrap.jar:/Users/java0904/Downloads/apache-tomcat-9.0.30/bin/tomcat-juli.jar
    Tomcat started.

此时测试https://localhost:8443/看看是否可以访问，可以的话，则证明支持https协议  
，此时再访问https://localhost:8443/cas/login，将得到如下页面  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3NpbGtfamF2YQ_size_16_color_FFFFFF_t_70]  
用户名是casuser，密码是Mellon  
此时配置hosts文件

127.0.0.1 java.cas.juhe.cn

此时用域名去访问  
[https://java.cas.juhe.cn:8443/cas/login][https_java.cas.juhe.cn_8443_cas_login]一样是可以访问的;

### 服务端的配置更改，很关键 ###

#### 改HTTPSandIMAPS-10000001.json ####

接下来需要在/Users/java0904/Downloads/apache-tomcat-9.0.30/webapps/cas/WEB-INF/classes/services这个目录下面，修改HTTPSandIMAPS-10000001.json这个文件，增加http的支持，如下

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

#### 改application.properties文件 ####

接下来修改/Users/java0904/Downloads/apache-tomcat-9.0.30/webapps/cas/WEB-INF/classes目录下面的application.properties文件，添加如下代码

cas.tgc.secure=false
    cas.serviceRegistry.initFromJson=true

# 编辑客户端的代码 #

我这里用的是springboot，pom文件是
