+# Nacos 安装配置
+
+> [Nacos](https://nacos.io/zh-cn/) 是一款发现、配置和管理微服务的软件。
+
+## 1.预备环境准备
+
+Nacos 依赖 [Java](https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/) 环境来运行。如果您是从代码开始构建并运行Nacos，还需要为此配置 [Maven](https://maven.apache.org/index.html)环境，请确保是在以下版本环境中安装使用:
+
+1. 64 bit OS，支持 Linux/Unix/Mac/Windows，推荐选用 Linux/Unix/Mac。
+2. 64 bit JDK 1.8+；[下载](http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html) & [配置](https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/)。
+3. Maven 3.2.x+；[下载](https://maven.apache.org/download.cgi) & [配置](https://maven.apache.org/settings.html)。
+
+## 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
+
+```bash
+git clone https://github.com/alibaba/nacos.git
+cd nacos/
+mvn -Prelease-nacos 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](https://github.com/alibaba/nacos/releases) 下载 `nacos-server-$version.zip` 包。
+
+```bash
+  unzip nacos-server-$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
+```
+
+### 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/instances?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。
