EUREKA Client 无法连接注册中心问题解决方案【连接被拒绝、不支持SSL协议消息、不能向任意已知的服务器发送请求】

EUREKA Client 无法连接注册中心问题解决方案【连接被拒绝、不支持SSL协议消息、不能向任意已知的服务器发送请求】

版本：HOXTON.SR8

主要报错信息如下：

  1. //无法连接注册中心
  2. DiscoveryClient_CLIENT1/host.docker.internal:client1:8089 - registration failed Cannot execute request on any known server
  3.  
  4. com.netflix.discovery.DiscoveryClient    : DiscoveryClient_CLIENT1/host.docker.internal:client1:8089 - was unable to send heartbeat!
  5.  
  6. com.netflix.discovery.shared.transport.TransportException: Cannot execute request on any known server
  7.  
  8. //使用了https协议
  9. Caused by: javax.net.ssl.SSLException: Unsupported or unrecognized SSL message

我的方法也许不能帮你解决问题，但是一定能帮你排除掉一部分问题！

解决方法如下：

        1. application.yml文件或者properties文件中的service-url替换为serviceUrl，default-zone替换为defaultZone，亲测有用，能解决一部分问题，重点检查拼写！！！

        2. 服务端关闭验证：

                

  1. security: 
  2.     basic: 
  3.         enabled: false

        感觉没啥效果

        3. client端 fetch-registry未开启，在配置文件中把  eureka.client.fetch-registry设置为true，亲测有用，不过注册中心就别开这个配置了

        4. 使用了安全验证之后，服务端需要关闭CSRF验证，关闭方法在后面 

        5. 注册地址注意使用http协议而不要使用https协议，亲测有用，IDE有时候会自动帮你修改为https协议

        6. 服务端server.port端口就是你的注册中心注册服务的端口，如果你的server.port端口就是8761，那么你的注册地址中端口也是8761！

        7. 注册地址拼写错误，例如http://root:root@localhost:8761/eurake，看出了错误的地方了吗？注意 eurake 这个地方，正确的拼写是 eureka !一定要详细检查，我就是这个地方弄错了！

        8. application.yml 文件要放在resources文件夹中，注意检查，很多朋友都是这个问题

        9. server端的启动一定要在client端之前！！！ 

  

附上我的配置,实在不行可以用我的试试：

server端：application.yml

  1. server:
  2.   port: 8761
  3.   address: localhost
  4. spring:
  5.   security:
  6.     user:
  7.       name: root
  8.       password: root
  9. security:
  10.   basic:
  11.     enabled: false
  12. eureka:
  13.   instance:
  14.     hostname: localhost
  15.   client:
  16.     fetch-registry: false
  17.     register-with-eureka: false
  18.     serviceUrl:
  19.       defaultZone: http://root:root@localhost:8761/eureka
