前言

此文章介绍如何部署spring cloud 服务端程序(Eureka、Config和Gateway)
此centos上已经安装了jdk17，没有安装的可以看前面的文章
项目源码已经放到gitee上了，也可以直接clone下来运行

一、部署EurekaServer

1. 添加pom依赖

<?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>3.0.7</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.supermarket</groupId>
	<artifactId>eurekaserver</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<name>eurekaserver</name>
	<description>Demo project for Spring Boot</description>
	<properties>
		<java.version>17</java.version>
		<spring-cloud.version>2022.0.2</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>
	<repositories>
		<repository>
			<id>netflix-candidates</id>
			<name>Netflix Candidates</name>
			<url>https://artifactory-oss.prod.netflix.net/artifactory/maven-oss-candidates</url>
			<snapshots>
				<enabled>false</enabled>
			</snapshots>
		</repository>
	</repositories>

</project>

2. 启动类上添加@EnableEurekaServer

@SpringBootApplication
@EnableEurekaServer
public class EurekaServerApplication {

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

}

3. 配置文件修改

server:
  port: 8761

eureka:
  instance:
    preferIpAddress: true
  client:
    registerWithEureka: false
    fetchRegistry: false
    serviceUrl:
      defaultZone: http://127.0.0.1:${server.port}/eureka/

4. 查看效果

访问 http://localhost:8761/

二、部署ConfigServer

启动成功后，服务注册到eureka server上

1. 添加pom依赖

<?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>3.0.7</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.supermarket</groupId>
	<artifactId>configserver</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<name>configserver</name>
	<description>Demo project for Spring Boot</description>
	<properties>
		<java.version>17</java.version>
		<spring-cloud.version>2022.0.2</spring-cloud.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-server</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>
	</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. 启动类上添加@EnableConfigServer

package com.supermarket.configserver;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.config.server.EnableConfigServer;

@SpringBootApplication
@EnableConfigServer
public class ConfigServerApplication {

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


}

3. 配置文件修改

server:
  port: 8888
spring:
  application:
    name: configserver
  cloud:
    config:
      server:
        git:
          # 这里为了简化，所以配置文件和仓库写到了一起，clone时会clone下整个仓库
          uri: https://gitee.com/xszchm/study-distribution.git
          search-paths:
            - configserver/src/main/resources/configs
        defaultLabel: master

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/

4. 在仓库上建立配置文件

foo-dev.yml

name: Tom

4. 查看效果

访问 http://localhost:8888/foo-dev.yml就可以看到效果
在这里插入图片描述
访问http://localhost:8761/ 可以看到服务注册到eureka server上了

三、部署Gateway

启动成功后，服务注册到eureka server上，路由配置文件从config server上获取

1. 添加pom依赖

<?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>3.0.7</version>
		<relativePath/> <!-- lookup parent from repository -->
	</parent>
	<groupId>com.supermarket</groupId>
	<artifactId>gateway</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<name>gateway</name>
	<description>Demo project for Spring Boot</description>
	<properties>
		<java.version>17</java.version>
		<spring-cloud.version>2022.0.2</spring-cloud.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-starter-gateway</artifactId>
		</dependency>

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

		<dependency>
			<groupId>org.springframework.cloud</groupId>
			<artifactId>spring-cloud-config-client</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. 启动类

package com.supermarket.gateway;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class GatewayApplication {

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

}

3. 配置文件修改

server:
  port: 8080

spring:
  application:
    name: gateway
  profiles:
    active: dev
  config:
    import: optional:configserver:http://localhost:8888 #配置中心地址

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/ #注册中心地址

4. 在仓库上建立配置文件

gateway-dev.yml

spring:
  cloud:
    gateway:
      routes: #路由
        - id: configserver
          uri: lb://configserver
          predicates:
            - Path=/configserver/**
          filters:
            - StripPrefix=1 # 转发之前去掉1层路径

4. 查看效果

访问 http://localhost:8080/configserver/foo-dev.yml 就可以看到效果
在这里插入图片描述

三、部署命令

nohup /root/program/jdk-17/bin/java -jar /root/program/eureka4/eurekaserver-0.0.1-SNAPSHOT.jar  > log.log 2>&1 &
