window环境：startup.cmd、shutdown.cmd

Linux环境：startup.sh、shutdown.sh

二、安装

Linux

解压压缩包

## 解压安装包，这里下载的是2.2.2版本的包 tar -zxvf nacos-server-2.2.2.tar.gz

解压时可以指定名字

window

window环境下nacos需要安装jdk环境并设置JAVA_HOME环境变量供cmd文件使用

window下单击启动可以对startup.cmd文件做修改

三、运行nacos

nacos可以单机模式运行也可集群模式

在0.7版本前单机模式使用的是内嵌数据库，0.7版本后增加了mysql数据源的支持能力

安装mysql数据库

初始化数据库，执行config/mysql-schema.sql创建响应的表

修改config/application.properties文件，配置mysql数据源

一、单机模式使用：

## 指定单机模式 
sh startup.sh -m standalone

二、集群模式

准备不同的nacos服务

可以使用多个机器，没有条件就使用单个机器不同端口模拟，但可能出现服务端之间通信端口的问题，最好用多个机器模拟

---

同样集群模式下修改config/application.properties文件增加数据源配置

修改cluster.conf配置文件中机器的ip:port用来对应不同的nacos服务器

## 默认集群模式启动 
sh startup.sh

登录浏览器访问对应的nacos服务器

http://ip:port/context >>>> http://ip地址:服务端口(默认是8848)/服务名(默认是nacos)

地址中的端口服务名都可以在application.properties中修改

三、登录查看

http://ip:port/nacos

http://ip:8848/nacos
