MySQL操作(安装前)#

创建用户

CREATE USER 'nacos'@'%' IDENTIFIED BY '密码';

赋予nacos库所有权限, 刷新权限

GRANT ALL PRIVILEGES ON nacos.* TO 'nacos'@'%';
FLUSH PRIVILEGES;

创建库

CREATE DATABASE `nacos` /*!40100 DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci */ /*!80016 DEFAULT ENCRYPTION='N' */;

导入表：下载2.2.3版本sql文件：点这

use nacos;
source nacos-mysql-schema2-2-3.sql

安装Nacos#

根据nacos-k8s进行yaml文件编写

根据nacos-docker的环境变量

SPRING_DATASOURCE_PLATFORM 默认:空 若不指定为mysql, 则一直是embedded嵌入式存储模式

nacos.yaml
