一、容灾server集群
复制上例中的server项目两个,分别命名为x-server2和x-server3,修改yml配置
①端口:三个服务器的端口分别为9010,9011,9012
②defaultZone:三个服务器的defaultZone分别为对方,即排除自己之外的两个,即A填写BC的地址,B填写AC的地址,C填写AB的地址。
③name:修改三个server的name,做区分。
三个server的具体yml配置如下
server: port: 9010 eureka: instance: hostname: localhost client: registerWithEureka: false fetchRegistry: false serviceUrl: defaultZone: http://localhost:9011/eureka/,http://localhost:9012/eureka/ server: enable-self-preservation: false spring: application: name: eureka-server-9010
server: port: 9011 eureka: instance: hostname: localhost client: registerWithEureka: false fetchRegistry: false serviceUrl: defaultZone: http://localhost:9010/eureka/,http://localhost:9012/eureka/ server: enable-self-preservation: false spring: application: name: eureka-server-9011
server: port: 9012 eureka: instance: hostname: localhost client: registerWithEureka: false fetchRegistry: false serviceUrl: defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/ server: enable-self-preservation: false spring: application: name: eureka-server-9012
为了演示配置用3台,两台即可,最好物理上做区分为2台。
二、eureka client集群
复制上例中的client项目两个,分别命名为x-client2和x-client3,修改yml配置
①端口:三个客户端的端口分别为9020,9021,9022
②defaultZone:三个客户端的defaultZone分别为三个server
③name:三个客户端分别修改name,做区分
三个客户端的yml配置如下:
server: port: 9020 eureka: client: serviceUrl: defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/ spring: application: name: eureka-client-9020
server: port: 9021 eureka: client: serviceUrl: defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/ spring: application: name: eureka-client-9021
server: port: 9022 eureka: client: serviceUrl: defaultZone: http://localhost:9010/eureka/,http://localhost:9011/eureka/,http://localhost:9012/eureka/ spring: application: name: eureka-client-9022
结果如下:
可尝试关闭掉当前注册进的server,然后观察其他两个server的变化情况
以上!
