[大数据]springcoud(1)----eureka服务注册中心搭建

1.导入 依赖

建议直接使用idea导入依赖

pom.xml

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.6.3</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.cz</groupId>
    <artifactId>eurekaCenter</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>eurekaCenter</name>
    <description>eurekaCenter</description>
    <properties>
        <java.version>1.8</java.version>
        <spring-cloud.version>2021.0.0</spring-cloud.version>
    </properties>
    <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-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${spring-cloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

2.编写yml文件

server:
  port: 9001
eureka:
  instance:
    ip-address: true  #   以ip形式进行注册
    lease-expiration-duration-in-seconds: 90  # 至少90s发送一次心跳给我
    lease-renewal-interval-in-seconds: 30   #   设置30s就发送一次心跳
  client:
    register-with-eureka: false  #是否向服务注册中心注册自己    默认true
    fetch-registry: false   # 是否向服务注册中心拉去注册表信息    默认true
    service-url:
      defaultZone: http://localhost:9001/eureka
spring:
  application:
    name: eurekaCenter

3.启动类上加注解支持@EnableEurekaServer

package com.cz;

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

@SpringBootApplication
@EnableEurekaServer
public class EurekaCenterApplication {

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

}

4.启动项目

访问localhost:9001即可
