一. Nacos Windows 单机版下载与运行

1. SpringCloud Alibaba Nacos 服务注册和配置中心,更易于构建云,原生应用的动态服务发现,配置管理,和服务管理平台,就是以前配置中心 Config + 注册中心 Eureka + Bus 消息总线的组合体
2. SpringBoot+SpringCloud Alibaba支持 Nacos 的父项目容器 pom 示例

3. 子项目使用 Nacos pom 示例

<?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>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloudalibaba-config-nacos-client3377</artifactId>

    <dependencies>
        <!-- nacos config (使用Nacos配置配置中心功能)-->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>

            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

4. Nacos github 访问地址: https://github.com/alibaba/Nacos
5. 使用 Nacos 需要下载安装 gitHub 下载地址 https://github.com/alibaba/nacos/tags
   
6. 将下载后的压缩包解压到非中文路径下,进入 bin 目录, 双击 startup.cmd 文件运行,默认端口号为 8848
   
7. 运行成功后访问"http://localhost:8848/nacos" 运行 nacos 的IP地址:端口号/nacos,输入用户名密码进行登入,默认都是 nacos
