springcloud学习之eureka的server和client搭建

1.eurekaServer的搭建：
pom.xml中必要的依赖：

<dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>

application.yml配置：

spring:
  profiles:
    active: dev2
---
spring:
  application:
    ###当前服务名
    name: eureka-peer
  profiles: dev

server:
  ##端口号
  port: 10000



---
spring:
  profiles: dev1
  application:
    name: eureka-peer2
server:
  port: 10001


---
spring:
   profiles: dev2
   application:
     name: eureka-peer3
server:
  port: 10002

---
eureka:
  instance:
    hostname: dev1
  client:
    ##检索服务
    fetch-registry: false
    ##是否将自己注册到eureka
    register-with-eureka: false
    ##客户端默认去这个地址找注册中心
    service-url:
      defaultZone: http://localhost:10000/eureka/,http://localhost:10001/eureka/,http://localhost:10002/eureka/
  server:
    ### 当eureka启动时，不能从集群节点中获取到instance注册信息，应该等多久
    wait-time-in-ms-when-sync-empty: 0
    enable-self-preservation: true
    ###eureka多长时间更新一次数据
    peer-eureka-nodes-update-interval-ms: 100000

启动类的注解配置：

package com.eurekaServer;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.cloud.netflix.eureka.server.EnableEurekaServer;
@EnableEurekaServer
@SpringBootApplication
public class EurekaServerApplication {

	public static void main(String[] args) {
		SpringApplication.run(EurekaServerApplication.class, args);
	}
}

2. eurekaClient的配置：
   pom.xml必要依赖：

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
		</dependency>

		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>

application.proprties配置：

eureka.port1=10000
eureka.port2=10001
eureka.port3=10002
server.port=8763

eureka.instance.hostname=localhost
spring.application.name=eureka-client
eureka.client.healthcheck.enabled=true
#在此指定服务注册中心地址
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${eureka.port1}/eureka/,http://${eureka.instance.hostname}:${eureka.port2}/eureka/,http://${eureka.instance.hostname}:${eureka.port3}/eureka/
management.endpoints.web.exposure.include= "*"
management.endpoints.web.cors.allowed-origins="*"
management.endpoints.web.cors.allowed-methods= "*"

启动类的配置：

package come.eurekaclient;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.eureka.EnableEurekaClient;

@SpringBootApplication
@EnableEurekaClient
public class EurekaclientApplication {

	public static void main(String[] args) {
		SpringApplication.run(EurekaclientApplication.class, args);
	}

}

3.springboot在linux环境上的发布：
springboot官方是建议以jar包的形式发布

发布eurekaServer：
cd /usr/local/src/
git clone -b master https://github.com/luohong12/springcloud-eurekaServer.git
cd springcloud-eurekaServer/
mvn clean install
mkdir /usr/local/project
cp target/Eureka-Server-0.0.1-SNAPSHOT.jar /usr/local/project/
cd /usr/local/project/
mkdir logs
java -jar Eureka-Server-0.0.1-SNAPSHOT.jar -> logs/EurekaServer.out &
tail -f logs/EurekaServer.out
访问检验是否发布成功：

eurekaClient发布方式是一样的，这里就不写，直接看结果：
