Eureka系列---【Eureka如何实现高可用?】
Eureka的高可用解决方案
一、双机部署
分析:
1.Eureka的server端相互注册,自动相互同步应用信息;
2.Eureka的client端注册到任意一个上面即可,但为了保险起见,我们常同时注册到两个上面,来防止client注册到server1后,server1挂掉,client重启后注册不上;
server1的配置文件:
eureka:
client:
service-url:
defaultZone: http://localhost:8762/eureka
register-with-eureka: false
server2的配置文件:
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka
register-with-eureka: false
client的配置文件:
eureka:
client:
service-url:
defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka
二、多机部署
分析:
1.server端两两相互注册;
2.client端同时注册到三个上面;
server1的配置文件:
eureka: client: service-url: defaultZone: http://localhost:8762/eureka,http://localhost:8763/eureka
register-with-eureka: false
server2的配置文件:
eureka: client: service-url: defaultZone: http://localhost:8761/eureka,http://localhost:8763/eureka
register-with-eureka: false
server3的配置文件:
eureka: client: service-url: defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka
register-with-eureka: false
client的配置文件:
eureka: client: service-url: defaultZone: http://localhost:8761/eureka,http://localhost:8762/eureka,http://localhost:8763/eureka
愿你走出半生,归来仍是少年!
