一、说明

上一篇文章对 eureka server 进行了集群化，现在我们对 zuul 也来集群化

二、修改 zuul 的配置文件

application.yml

spring:
  application:
    name: zuul
  profiles:
    active: zuul1

新增 application-zuul1.yml

server:
  port: 8769

spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
  cloud:
    bus:
      enabled: true
      trace:
        enabled: true

eureka:
  client:
    registryFetchIntervalSeconds: 5
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/,http://localhost:8760/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS

zuul:
  routes:
    toclient1:
      path: /toclient1/**
      serviceId: client1
    toclient2:
      path: /toclient2/**
      serviceId: client2

新增 application-zuul2.yml

server:
  port: 8770

spring:
  rabbitmq:
    host: localhost
    port: 5672
    username: guest
    password: guest
  cloud:
    bus:
      enabled: true
      trace:
        enabled: true

eureka:
  client:
    registryFetchIntervalSeconds: 5
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/,http://localhost:8760/eureka/
  instance:
    leaseRenewalIntervalInSeconds: 10
    health-check-url-path: /actuator/health
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    prefer-ip-address: true

management:
  endpoints:
    web:
      exposure:
        include: "*"
  endpoint:
    health:
      show-details: ALWAYS

zuul:
  routes:
    toclient1:
      path: /toclient1/**
      serviceId: client1
    toclient2:
      path: /toclient2/**
      serviceId: client2

指向 zuul1 启动一个 zuul，再指向 zuul2 启动一个

三、完成集群化
