## 简介 ##

**说明**

本文用示例介绍如何搭建Nacos服务并在SpringBoot中整合Nacos。

**官方网址**

官网文档：[https://nacos.io/zh-cn/docs/what-is-nacos.html][https_nacos.io_zh-cn_docs_what-is-nacos.html]

github网址：[https://github.com/alibaba/nacos][https_github.com_alibaba_nacos]

## 1.安装Nacos ##

下载：[https://github.com/alibaba/nacos/releases][https_github.com_alibaba_nacos_releases]

本处我下载的版本为：nacos-server-1.4.3

## 2.运行Nacos ##

**Linux/Unix/Mac**

启动命令(standalone代表着单机模式运行，非集群模式):

sh startup.sh -m standalone

如果您使用的是ubuntu系统，或者运行脚本报错提示\[\[符号找不到，可尝试如下运行：

bash startup.sh -m standalone

**Windows**

启动命令(standalone代表着单机模式运行，非集群模式):

startup.cmd -m standalone

本处是Windows，运行结果：

## 3.访问nacos ##

访问地址：[http://localhost:8848/nacos][http_localhost_8848_nacos]  
账号：nacos  
密码：nacos

**配置管理**

## 4.创建SpringBoot项目 ##

### **配置文件** ###

**bootstrap.yml**

spring:
      profiles:
        active: test
      cloud:
        nacos:
          server-addr: 127.0.0.1:8848
          username: nacos
          password: nacos
          config:
            file-extension: yml
    #        namespace: ${spring.profiles.active}
    #        # 公共的配置文件
    #        shared-configs:
    #          - data-id: common-${spring.profiles.active}.${spring.cloud.nacos.config.file-extension}
    #            group: DEFAULT_GROUP
    #            refresh: true
    #      discovery:
    #        namespace: ${spring.profiles.active}

**application.yml**

server:
      port: 9012
    
    spring:
      application:
        name: order

## 5.启动SpringBoot项目 ##

使用Idea启动order项目：

nacos结果：

可以看到，服务已经成功注册到nacos。

此时即可使用SpringCloud的feign进行微服务调用，本处省略。
