2.下载源码或者安装包

你可以通过源码和发行包两种方式来获取 Nacos。
从 Github 上下载源码方式
git clone https://github.com/alibaba/nacos.git
cd nacos/
mvn -Prelease-nacos -Dmaven.test.skip=true clean install -U
ls -al distribution/target/
// change the $version to your actual path
cd distribution/target/nacos-server-$version/nacos/bin
下载编译后压缩包方式
您可以从 最新稳定版本 下载 nacos-server-$version.zip 包。
unzip nacos-server-$version.zip 或者 tar -xvf nacos-server-$version.tar.gz
cd nacos/bin
3.启动服务器
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：
cmd startup.cmd
或者双击startup.cmd运行文件。
4.服务注册&发现和配置管理
服务注册
curl -X POST ‘http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080’
服务发现
curl -X GET ‘http://127.0.0.1:8848/nacos/v1/ns/instance/list?serviceName=nacos.naming.serviceName’
发布配置
curl -X POST “http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=HelloWorld”
获取配置
curl -X GET “http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test”
5.关闭服务器
Linux/Unix/Mac
sh shutdown.sh
Windows
cmd shutdown.cmd
或者双击shutdown.cmd运行文件。

DOCKER uick Start

Run the following command：

Clone project

git clone --depth 1 https://github.com/nacos-group/nacos-docker.git
cd nacos-docker

Standalone Derby

docker-compose -f example/standalone-derby.yaml up

Standalone Mysql

docker-compose -f example/standalone-mysql.yaml up

Cluster

docker-compose -f example/cluster-hostname.yaml up 

Service registration

curl -X PUT 'http://127.0.0.1:8848/nacos/v1/ns/instance?serviceName=nacos.naming.serviceName&ip=20.18.7.10&port=8080'

Service discovery

  curl -X GET 'http://127.0.0.1:8848/nacos/v1/ns/instances?serviceName=nacos.naming.serviceName'

Publish config

curl -X POST "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test&content=helloWorld"

Get config

  curl -X GET "http://127.0.0.1:8848/nacos/v1/cs/configs?dataId=nacos.cfg.dataId&group=test"

Open the Nacos console in your browser

spring.application.name=nacos
spring.cloud.nacos.discovery.server-addr=102.168.88.127:8848

在 Nacos Spring Cloud 中，dataId 的完整格式如下：
${prefix}-${spring.profile.active}.${file-extension}

    prefix 默认为 spring.application.name 的值，也可以通过配置项 spring.cloud.nacos.config.prefix来配置。
    spring.profile.active 即为当前环境对应的 profile，详情可以参考 Spring Boot文档。 注意：当 spring.profile.active 为空时，对应的连接符 - 也将不存在，dataId 的拼接格式变成 ${prefix}.${file-extension}
    file-exetension 为配置内容的数据格式，可以通过配置项 spring.cloud.nacos.config.file-extension 来配置。目前只支持 properties 和 yaml 类型。
