收集各种资料搭建的spring cloud后记录搭建过程

一、eureka server搭建步骤

pom加入依赖

	<parent>
	    <groupId>org.springframework.boot</groupId>
	    <artifactId>spring-boot-starter-parent</artifactId>
	    <version>1.5.9.RELEASE</version>
	</parent>
	
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    
	<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka-server</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-config</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

启动类

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

启动application.yml,注意yml的key value中间有空格,不能用tab键,同一层注意缩进

hosts增加127.0.0.1 peer1 peer2

spring:
  profiles: peer1
  application:
    name: Eureka-Server-1
eureka:
  instance:
    hostname: peer1
    #配置主机名
  client:
    register-with-eureka: true
    #配置服务注册中心是否以自己为客户端进行注册(配置false)
    fetch-registry: true
    #是否取得注册信息(配置false)
    service-url:
      defaultZone: http://peer2:7002/eureka/
server:
  port: 7001
  
---
spring:
  profiles: peer2
  application:
    name: Eureka-Server-1
eureka:
  instance:
    hostname: peer2
    #配置主机名
  client:
    register-with-eureka: true
    #配置服务注册中心是否以自己为客户端进行注册(配置false)
    fetch-registry: true
    #是否取得注册信息(配置false)
    service-url:
      defaultZone: http://peer1:7001/eureka/
server:
  port: 7002

打jar包后启动

java -jar xxxx.jar --spring.profiles.active=peer1

java -jar xxxx.jar --spring.profiles.active=peer2

二、eureka client搭建

pom依赖,附带hystrix熔断器

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.9.RELEASE</version>
	</parent>

	<dependencyManagement>
		<dependencies>
			<dependency>
				<groupId>org.springframework.cloud</groupId>
				<artifactId>spring-cloud-dependencies</artifactId>
				<version>Edgware.RELEASE</version>
				<type>pom</type>
				<scope>import</scope>
			</dependency>
		</dependencies>
	</dependencyManagement>

	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-eureka</artifactId>
		</dependency>
		<dependency> 
			<groupId>org.springframework.cloud</groupId> 
			<artifactId>spring-cloud-starter-hystrix</artifactId>
		</dependency>
		<dependency> 
			<groupId>org.springframework.boot</groupId> 
			<artifactId>spring-boot-starter-actuator</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.cloud</groupId> 
			<artifactId>spring-cloud-starter-config</artifactId>
		</dependency>
		<dependency>
		  <groupId>org.springframework.cloud</groupId>
		  <artifactId>spring-cloud-starter-bus-amqp</artifactId>
		</dependency>
	</dependencies>

启动类

@SpringBootApplication
@EnableDiscoveryClient
@EnableHystrix
public class Application {
	
    public static void main(String[] args) {
        ConfigurableApplicationContext run = run(Application.class, args);
    }

}

application.proerties

spring.application.name=mq-service
eureka.client.serviceUrl.defaultZone=http://peer1:7001/eureka/,http://peer2:7002/eureka/
permission-service.ribbon.NFLoadBalancerRuleClassName=com.netflix.loadbalancer.RandomRule
spring.cloud.bootstrap.enabled=true
management.security.enabled=false

config client配置文件 ,需要安装rabbitmq

bootstrap.yml

spring:
  application:
     name: mq-service
  cloud:
    config:
       profile: dev
       label: master
       discovery: 
           # 通过服务发现组建config server
           enabled: true
           service-id: config-server
       
eureka:
  client:
    service-url:
      defaultZone: http://peer1:7001/eureka/, http://peer2:7002/eureka/

rabbitmq:
   host: localhost
   port: 5672
   username: guest
   password: guest

三、zuul

pom

      <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.9.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-eureka</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zuul</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

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

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

启动类

@SpringBootApplication
@EnableZuulProxy
public class ZuulApplication {
	public static void main(String[] args) {
		new SpringApplicationBuilder(ZuulApplication.class).web(true).run(args);
	}
}

application.yml

server:
  port: 8888

spring:
  application:
    name: api-gateway

zuul:
   routes:
      mq-route:
          service-id: mq-service
          path: /mq-service/**
              
eureka:
  client:
    service-url:
      defaultZone: http://peer1:7001/eureka/, http://peer2:7002/eureka/

四、config server

pom

  	<parent>
	    <groupId>org.springframework.boot</groupId>
	    <artifactId>spring-boot-starter-parent</artifactId>
	    <version>1.5.9.RELEASE</version>
	</parent>
	
	<!--依赖管理中心-->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Edgware.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    
	<dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-config-server</artifactId>
        </dependency>
        <dependency>  
            <groupId>org.springframework.cloud</groupId>  
            <artifactId>spring-cloud-starter-eureka</artifactId>  
        </dependency>
    </dependencies>

启动类

@SpringBootApplication
@EnableConfigServer
@EnableEurekaClient
public class ConfigServerApplication {

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

application.yml

server:
  port: 8092

spring:
  application:
    name: config-server
  cloud:
    config:
     server:
      git:
       uri: git地址
       username:
       password:
       
eureka:
  client:
    service-url:
      defaultZone: http://peer1:7001/eureka/, http://peer2:7002/eureka/
