Nacos

Nacos 致力于帮助您发现、配置和管理微服务。Nacos 提供了一组简单易用的特性集，帮助您快速实现动态服务发现、服务配置、服务元数据及流量管理。

安装环境

🐖 ： JAVA和Maven之前装的就不做安装步骤描述

  1. MAC
  2. JDK1.8+ (java version "1.8.0_191")
  3. Maven 3.6.3

安装Nacos

Nacos版本：2.0.0-bugfix (Mar 30th, 2021)

此时最新版，如果需要其他版本自行下载。百度云盘中也是这个版本。

下载地址

官方地址：github.com/alibaba/nac…

链接: pan.baidu.com/s/1ppOfKViL…
密码: 2dth

下载源码或者安装包

🐖 ： 我是通过这种方式，先下载安装包的。git clone特别慢我就直接下载了

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 $version to your actual path
# 启动脚本目录
cd distribution/target/nacos-server-$version/nacos/bin

下载编译后压缩包方式

unzip nacos-server-$version.zip 或者 tar -xvf nacos-server-$version.tar.gz
 
cd nacos/bin

启动服务

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

ubuntu

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):

cmd startup.cmd -m standalone

关闭服务

Linux/Unix/Mac

sh shutdown.sh

Windows

cmd shutdown.cmd

Spring Cloud + Naocs

pom

版本依赖很重要，我用的基本上都是最新版

访问Nacos Server

反应还是很迅速的，哈哈😀

简单demo跑通了，后续更新其他参数和集群版本

做个笔记记录下来，以后方便自己用.有点粗糙，不断补充
