前言
Nacos 是一个开源的服务发现和配置管理平台，它支持动态服务发现、配置管理、服务健康检查和元数据管理等功能。使用 Docker 部署 Nacos 可以快速实现服务注册与发现的高可用性。本文将详细介绍如何在 Docker 环境下部署 Nacos，并配置高可用服务注册与发现。
环境准备
在开始部署之前，请确保您的系统已满足以下要求：
- 服务器环境：至少 2 核 CPU 和 4GB 内存。
- Docker 环境：Docker 版本需为 1.13.1 以上。
搭建Nacos操作过程
1. 拉取Nacos镜像
docker pull nacos/nacos-server:v2.1.2
2. 创建配置数据库
Nacos 使用 MySQL 作为配置数据库，因此需要创建数据库和表。以下是创建数据库和表的 SQL 脚本：
