资源编排是一项简化云计算资源管理和运维的服务。用户通过模板描述多个云资源的配置信息和依赖关系，通过模板创建资源栈，自动完成所有资源的创建和配置，以实现资源的统一管理和自动化运维等目的。服务本身免费，仅收取所使用资源的费用：如云主机、公网IP、云数据库实例等。
一、准备工作
1.说明
我们用wordpress模拟网站源代码，*.sql文件模拟网站数据库备份，将网站源代码迁移到位于华北-北京不同可用区的两台云主机上，将sql备份文件恢复到云数据库RDS MySQL上，云主机与云数据库都由京东云资源编排产品自动创建生成。
模板的常用参数说明详见：https://docs.jdcloud.com/cn/resource-orchestration/templates-structure
2.测试示意图
二、开始
1. 创建资源栈（模板）
打开控制台，选择管理-资源编排-资源栈，选择需要创建的资源栈所在的地域，支持华北-北京、华南-广州、华东-宿迁、华东-上海，我这里选择华北-北京，点击创建资源栈按钮。
点击我的模板，将原模板内容删除，复制下面的json代码到模板内容中（此json代码内容中创建的资源较多，所以代码较多，复制时仔细认真点），点击下一步

确认资源栈信息后，点击创建资源栈
ta创建完成后点击时间列表能够查看整个资源栈的创建过程
2. 测试上云
所有资源创建完成后，我们找到创建好的负载均衡实例公网IP，粘贴到浏览器打开查看效果
接下来我们将本地的MySQL数据库备份文件导入到我们创建的云数据库RDS MySQL中
备份本地数据库，命令如下：
1mysqldump -u用户名 -p密码 --single-transaction --set-gtid-purged=OFF -B 数据库名称 > /路径/导出文件名.sql
将本地MySQL备份完成后，我们需要创建一台与云数据库RDS MySQL在相同VPC的云主机（不在同一VPC默认情况下无法访问云数据库），创建云主机方法见：https://docs.jdcloud.com/cn/virtual-machines/create-instance
创建完云主机后，将本地备份的.sql文件上传到京东云对象存储
上传完备份SQL后，我们获取相应备份文件的外链地址
然后通过wget命令下载到上面我们创建的云主机
然后通过如下命令进行备份文件的导入
1mysql -h云数据库域名 -u用户名 -p 数据库名 < /云主机路径/导出文件名.sql
云数据库域名查看方式：
最大复制负载均衡公网IP到浏览器，查看结果：
注：京东云资源编排服务目前支持云主机、私有网络、负载均衡、云数据库RDS，详见：https://docs.jdcloud.com/cn/resource-orchestration/resource-type
