MicroServices Architecture Springcloud (iii) EUREKA (Registration center cluster chapter)

A: Cluster environment construction
First step: We create a new two registry project called Eureka_register_service_master, another called Eureka_register_service_backup

The application.properties configuration for Eureka_register_service_master is as follows

    server.port=7998    eureka.client.register-with-eureka=false    eureka.client.fetch-registry=false    spring.application.name=eureka-server    eureka.instance.hostname=master    eureka.client.serviceUrl.defaultZone=http://backup:7999/eureka/    #这里配置的是backup的地址    eureka_register_service_backup的application.properties配置如下

The application.properties configuration for Eureka_register_service_backup is as follows

`    server.port=7999eureka.client.register-with-eureka=falseeureka.client.fetch-registry=falsespring.application.name=eureka-servereureka.instance.hostname=backup#这里配置的是master的地址eureka.client.serviceUrl.defaultZone=http://master:7998/eureka/`    上面的配置端口分别是     master端口是7998

BACKUPR Port is 7999

Because I'm using the same machine, I need to bind the host.

127.0.0.1 Master

127.0.0.1 Backup

The second step: Add boot files are Applicationmaster.java,applicationbackup.java

The contents of the code are the same

        @EnableEurekaServer    @SpringBootApplication    public class ApplicationMaster {        public static void main(String[] args) {            SpringApplication.run(ApplicationMaster.class, args);         }    }    @EnableEurekaServer    @SpringBootApplication    public class ApplicationBackUp {        public static void main(String[] args) {            SpringApplication.run(ApplicationBackUp.class, args);        }    }   

Step Three: Start

If the jar is started, the parameter--spring.profiles.active=matser or--spring.profiles.active=backup is required.

The first method is to start with the jar command

' Java-jar Eureka_register_service_matser-1.0.0.jar--spring.profiles.active=matser

 java -jar eureka_register_service_backup-1.0.0.jar --spring.profiles.active=backup`     架构代码如下：     ![](http://i2.51cto.com/images/blog/201802/08/e143be457842bf385ec7e011c6f70093.jpg?x-oss-process=image/watermark,size_16,text_QDUxQ1RP5Y2a5a6i,color_FFFFFF,t_100,g_se,x_10,y_10,shadow_90,type_ZmFuZ3poZW5naGVpdGk=)
