SpringCloud 实战五：Eureka集群环境搭建

1、创建模块

2、设置pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <parent>
        <artifactId>cloud2020</artifactId>
        <groupId>com.laoxu.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloud-eureka-server7002</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-server</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-actuator</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId>
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.laoxu.springcloud</groupId>
            <artifactId>cloud-api-common</artifactId>
            <version>1.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

3、单机服务模拟多台机器，修改hosts文件

4、7001和7002互相注册

7001：

server:
  port: 7001

spring:
  application:
    name: cloud-eureka-server

eureka:
  instance:
    hostname: eureka7001.com
  client:
    # false表示不再注册中心注册自己
    register-with-eureka: false
    # false表示自己端就是注册中心
    fetch-registry: false
    service-url:
      defaultZone: http://eureka7002.com:7002/eureka

7002：

server:
  port: 7002

spring:
  application:
    name: cloud-eureka-server2

eureka:
  instance:
    hostname: eureka7002.com
  client:
    # false表示不再注册中心注册自己
    register-with-eureka: false
    # false表示自己端就是注册中心
    fetch-registry: false
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka

5、启动7001和7002

http://eureka7001.com:7001/

http://eureka7002.com:7002/

6、宏观图

7、支付模块和消费模块注册到集群注册中心中

支付模块：

server:
  port: 8001

spring:
  application:
    name: cloud-payment-service
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: org.gjt.mm.mysql.Driver
    url: jdbc:mysql://106.54.196.44:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false
    username: root
    password: password

eureka:
  client:
    # 将自己注册进eureka中心
    register-with-eureka: true
    # 是否抓取注册信息，默认为true
    fetch-registry: true
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka, http://eureka7002.com:7002/eureka

mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.laoxu.springcloud.entities

消费模块：

server:
  port: 80
spring:
  application:
    name: cloud-order-consumer

eureka:
  client:
    # 将自己注册进eureka中心
    register-with-eureka: true
    # 是否抓取注册信息，默认为true
    fetch-registry: true
    service-url:
      defaultZone: http://eureka7001.com:7001/eureka, http://eureka7002.com:7002/eureka

8、查看两个注册中心

http://eureka7001.com:7001/

http://eureka7002.com:7002/

至此，集群搭建完成！
