部署Nacos时，可选择本地或MySQL作为存储。本例中，我们选用MySQL。

1. 前置条件

1. ✨ubuntu server 22.04 LTS 安装与配置✨

2. ✨二进制部署任意版本docker✨

3. 跨环境部署艺术：简化中间件连接策略

2. docker 部署

nacos已经出到很新了后续我再整新版本，本文部署的是2.0.3老版本。连接mysql的地址是 app-mysql1.basic.tanqidi.com 如果忘记需要回顾 跨环境部署艺术：简化中间件连接策略。

https://nacos.io/

https://github.com/alibaba/nacos/tree/2.0.3/distribution/conf

1. 到mysql中创建名为 nacos 的数据库

2. 导入 nacos-mysql.sql 到名为 nacos 的数据库里

docker run \
-e MODE=standalone \
-e SPRING_DATASOURCE_PLATFORM=mysql \
-e MYSQL_SERVICE_HOST=app-mysql1.basic.tanqidi.com \
-e MYSQL_SERVICE_PORT=3306 \
-e MYSQL_SERVICE_DB_NAME=nacos \
-e MYSQL_SERVICE_USER=root \
-e MYSQL_SERVICE_PASSWORD=123456 \
-p 8848:8848 \
-p 9848:9848 \
-p 9849:9849 \
-p 7848:7848 \
-d \
--restart=always \
--name nacos-2.0.3 \
nacos/nacos-server:2.0.3

3. Kubernetes 部署
