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

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

栈名称：资源编排测试
超时时间 (分钟)：10
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
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：
