3. Multiple Eureka nodes are deployed

---------------------------peer1------------------------------
 server:
   port: 8761
 eureka:
   instance:
     hostname: peer1
     preferIpAddress: false
   client:
     registerWithEureka: true
     fetchRegistry: true
     serviceUrl:
       defaultZone: http://peer1:8761/eureka/,http://peer2:8762/eureka/
   server:
     enable-self-preservation: False # Disable self-protection
     eviction-interval-timer-in-ms: Set the cleaning interval to 60000 by default
 spring:
   application:
     name: eureka
Copy the code

 ---------------------------peer2------------------------------
  server:
    port: 8762
  eureka:
    instance:
      hostname: peer2
      preferIpAddress: false
    client:
      registerWithEureka: true
      fetchRegistry: true
      serviceUrl:
        defaultZone: http://peer1:8761/eureka/,http://peer2:8762/eureka/
