启动nacos服务注册中心

1）下载nacos-server

下载地址：https://github.com/alibaba/nacos/releases
找到：nacos-server-1.3.2.zip

2）解压启动

unzip nacos-server-1.3.2.zip
cd nacos-server-1.3.2/bin
linux启动方式：startup.sh -m standalone
window启动方式：startup.cmd -m standalone
关闭：shutdown.sh / shutdown.cmd

注：如果windown启动提示JAVA_HOME找不到，可以设置JAVA_HOME环境变量，或者修改startup.cmd文件，把JAVA_HOME地址改为本地jdk安装目录 下面是修改startup.cmd文件

把
if not exist "%JAVA_HOME%\bin\java.exe" echo Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better! & EXIT /B 1
set "JAVA=%JAVA_HOME%\bin\java.exe"
改为
if not exist "D:\jdk\install\jre\bin\java.exe" echo Please set the JAVA_HOME variable in your environment, We need java(x64)! jdk8 or later is better! & EXIT /B 1
set "JAVA=D:\jdk\install\jre\bin\java.exe"
