Spring Cloud 搭建eureka

首先是版本是

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.6.RELEASE</version>
        <relativePath/>
    </parent>

 <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <java.version>1.8</java.version>
        <spring.cloud.version>Dalston.SR4</spring.cloud.version>
        <spring-boot-admin.version>1.5.4</spring-boot-admin.version>
    </properties>

首先是单节点的

spring:
  profiles:
    active: aliyun


---
spring:
  profiles: aliyun
server:
  port: 8765

eureka:
  instance:
    hostname: registry1
  client:
    registerWithEureka: false
    fetchRegistry: false
    service-url:
      defaultZone: http://${security.user.name}:${security.user.password}@${eureka.instance.hostname}:${server.port}/eureka/

security:
  user:
    name: user
    password: ${REGISTRY_SERVER_PASSWORD:password}

可以看出来运行是可以了但是因为是单节点就没有分片这些显示了。其中在配置文件中的registerWithEureka和fetchRegistry是为了让eureka互相注册作为一个集群，如果都是false那么当前的服务器是唯一的服务器

接下来是集群

首先我尝试了用ip地址直接配置

spring:
  profiles:
    active: aliyun1


---
spring:
  profiles: aliyun
server:
  port: 8761

eureka:
  instance:
    ip-address: 127.0.0.1
  client:
    registerWithEureka: true
    fetchRegistry: false
    service-url:
      defaultZone: http://${security.user.name}:${security.user.password}@127.0.0.1:${server.port}/eureka/

security:
  user:
    name: user
    password: ${REGISTRY_SERVER_PASSWORD:password}

test:
  hostname: registry2
  port: 8762


---
spring:
  profiles: aliyun1
server:
  port: 8762

eureka:
  instance:
    ip-address: 127.0.0.1
  client:
    registerWithEureka: true
    fetchRegistry: true
    service-url:
      defaultZone: http://${security.user.name}:${security.user.password}@127.0.0.1:${server.port}/eureka/

security:
  user:
    name: user
    password: ${REGISTRY_SERVER_PASSWORD:password}

test:
  hostname: registry1
  port: 8761

结果界面显示

结果这两个分区都是挂掉的。。。。无效

然后修改了配置

spring:
  profiles:
    active: aliyun


---
spring:
  profiles: aliyun
server:
  port: 8761

eureka:
  instance:
    hostname: registry1
  client:
    registerWithEureka: true
    fetchRegistry: true
    service-url:
      defaultZone: http://${security.user.name}:${security.user.password}@${test.hostname}:${test.port}/eureka/

security:
  user:
    name: user
    password: ${REGISTRY_SERVER_PASSWORD:password}

test:
  hostname: registry2
  port: 8762


---
spring:
  profiles: aliyun1
server:
  port: 8762

eureka:
  instance:
    hostname: registry2
  client:
    registerWithEureka: true
    fetchRegistry: true
    service-url:
      defaultZone: http://${security.user.name}:${security.user.password}@${test.hostname}:${test.port}/eureka/

security:
  user:
    name: user
    password: ${REGISTRY_SERVER_PASSWORD:password}

test:
  hostname: registry1
  port: 8761

效果，分区已经可以正常使用了
