准备工作：

Linux / MacOS

预装一个 MySQL

1. 下载 Nacos

链接： https://github.com/alibaba/nacos/releases

下载最新版（2.0.4）即可。

下载解压后文件结构是这样的

2. 初始化 Mysql

创建 Mysql 数据库 nacos-dev

跑 conf/nacos-mysql.sql 下的初始化脚本

➜  nacos cat conf/nacos-mysql.sql

3. 配置 nacos 支持 MySQL

编辑 conf/application.properties (请根据实际情况修改)

spring.datasource.platform=mysql
db.num=1
db.url.0=jdbc:mysql://mysql.jansora.app:3306/nacos-prod?characterEncoding=utf8&connectTimeout=1000&socketTimeout=3000&autoReconnect=true&useUnicode=true&useSSL=false&serverTimezone=UTC
db.user.0=nacos
db.password.0=nacos

启动 nacos

bash bin/startup.sh -m standone
