一.前言

1.1简介

Nacos是阿里巴巴开源的一款支持服务注册与发现，配置管理以及微服务管理的组件。用来取代以前常用的注册中心（zookeeper , eureka等等），以及配置中心（spring cloud config等等）。Nacos是集成了注册中心和配置中心的功能，做到了二合一。

二.Nacos部署

2.1 创建数据库用户并初始化配置

CREATE DATABASE IF NOT EXISTS nacos DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
grant all privileges on nacos.* to nacos@'%' identified by '*******' with grant option;
flush privilages;

导入nacos初始化sql
