弹性伸缩可以结合资源编排来创建TiDB集群，并通过伸缩组的扩缩容能力来管理TiDB集群。本文为您介绍通过弹性伸缩创建和管理TiDB集群的方法，根据TiDB集群的实时情况实现该集群中ECS实例的自动扩缩容。
前提条件
您已拥有资源编排ROS的操作权限。
您已拥有弹性伸缩的操作权限。
您已拥有云服务器ECS的操作权限。
背景信息
伸缩组目前不支持直接关联TiDB集群，您可以先通过资源编排ROS创建伸缩组和TiDB集群，然后使用伸缩组的扩缩容功能管理TiDB集群。本文适用于如下场景：
您的业务数据存储在TiDB集群中。
您需要通过弹性扩缩容功能管理TiDB集群。
您需要在TiDB Dashboard界面对TiDB集群进行可视化分析及诊断。
操作步骤
本步骤以使用资源编排创建伸缩组关联的最小拓扑架构TiDB集群为例，该集群包含TiDB Servers，PD Cluster和TiKV Cluster三个组件（角色），具体操作步骤如下所示。
步骤一：创建资源栈
本步骤以创建地域选择华北5（呼和浩特）为例。
登录资源编排ROS控制台。
在左侧导航栏中，单击资源栈。
在顶部菜单栏处，选择资源栈所在地域为华北5（呼和浩特）。
在资源栈列表页面，单击创建资源栈，然后在下拉列表中选择使用ROS。
在创建资源栈页面的选择模板阶段，根据需要选择指定模板，然后单击下一步。
模板相关配置项如下所示：
指定模板：模板是一个 JSON或YAML文件，该文件描述了资源栈的资源和属性。请您保持默认选项，即选择已有模板。
模板录入方式：包含使用url、输入模板、我的模板、共享模板四种方式。请您保持默认选项，即输入模板方式。
模板内容：支持在该区域输入ROS或Terraform两种模板方式。其中，选择ROS模板方式时，在ROS页签下，您可以选择输入JSON、YAML两种类型的模板内容。
本步骤以可实现简单功能的ROS脚本为例，请您在编辑区域根据需要自行创建JSON类型的ROS模板内容。

From the outside, TiKV is a distributed Key-Value storage engine that provides transactions. The basic unit of data storage is Region. Each Region is responsible for storing data in a Key Range (the left-closed and right-open interval from StartKey to EndKey). Each TiKV node is responsible for multiple Regions. TiKV''s API provides native support for distributed transactions at the KV key-value pair level, and provides the SI (Snapshot Isolation) isolation level by default, which is also the core of TiDB''s support for distributed transactions at the SQL level. After the SQL layer of TiDB finishes the SQL analysis, it will convert the SQL execution plan into the actual call to the TiKV API. Therefore, the data is stored in TiKV. In addition, the data in TiKV will automatically maintain multiple copies (three copies by default), which naturally supports high availability and automatic failover.' zh-cn: 'TiKV Server 数量。<br>存储节点: 负责存储数据，从外部看 TiKV 是一个分布式的提供事务的 Key-Value 存储引擎。存储数据的基本单位是 Region，每个 Region 负责存储一个 Key Range（从 StartKey 到 EndKey 的左闭右开区间）的数据，每个 TiKV 节点会负责多个 Region。TiKV 的 API 在 KV 键值对层面提供对分布式事务的原生支持，默认提供了 SI (Snapshot Isolation) 的隔离级别，这也是 TiDB 在 SQL 层面支持分布式事务的核心。TiDB 的 SQL 层做完 SQL 解析后，会将 SQL 的执行计划转换为对 TiKV API 的实际调用。所以，数据都存储在 TiKV 中。另外，TiKV 中的数据都会自动维护多副本（默认为三副本），天然支持高可用和自动故障转移。' MinValue: 3 Label: en: TiKV Server Count zh-cn: TiKV Server 数量 Default: 3 DateDiskSize: Default: 1000 Type: Number Description: zh-cn: TiKV 集群的数据容量,TiKV 硬盘大小配置建议 PCI-E SSD 不超过 2 TB，普通 SSD 不超过 1.5 TB。 单位：GB。 en: 'The data capacity of TiKV cluster, TiKV hard disk size configuration recommended PCI-E SSD not exceed 2 TB, ordinary SSD not exceed 1.5 TB.

说明本示例中的ROS脚本仅供示例，具体请您根据实际需求输入脚本内容。
可创建3个伸缩组且每个伸缩组包含3个ECS实例。
可创建用于监控和运维TiDB集群的跳板机器（即1台ECS实例）。
每个伸缩组可创建1个伸缩规则。
每个伸缩组可创建1个缩容类型的生命周期挂钩，用于TiDB集群缩容时，ECS实例从该集群中移除。
每个伸缩组可创建1个扩容类型的生命周期挂钩，用于TiDB集群扩容时，ECS实例加入到该集群中。
在配置参数阶段，设置资源栈名称和ECS配置区域中的实例密码，然后单击创建。
说明请您根据控制台提示输入模板相关参数信息。其中，实例密码为弹性伸缩扩容后云服务器ECS的登录密码。
资源栈创建完成后，在资源栈信息页签下，您可以查看资源栈名称、资源栈ID和状态等基本信息。
步骤二：登录TiDB Dashboard页面并查看TiDB集群
在资源栈列表中，找到已创建好的资源栈，单击资源栈ID。
在资源栈详情页，单击输出页签。
找到TiDB Dashboard：参数，单击对应值列下的URL。
非首次操作：该URL直接跳转至TiDB Dashboard页面。
首次操作：该URL先跳转至SQL 用户登录页面，您无需输入密码，单击登录，然后跳转至TiDB Dashboard页面。
在TiDB Dashboard页面的左侧导航栏，单击集群信息。
在实例页签下，您可以查看到集群中三个组件（角色）所包含伸缩组实例的初始化信息。
步骤三：查看TiDB集群归属的伸缩组
- 登录弹性伸缩控制台。
在左侧导航栏中，单击伸缩组管理。
在顶部菜单栏处，选择地域为华北5（呼和浩特）。
在伸缩组管理页面的伸缩组列表中，查看已成功创建的TiDB集群归属的伸缩组。
TiDB集群归属的3个伸缩组分别以TiKVServer、TiPDServer、TiDBServer开头命名，如下图所示。
找到TiDB集群中任一角色归属的伸缩组，在该伸缩组对应的伸缩组名称/ID列下，单击伸缩组ID。
单击实例列表页签下的手动创建。
在手动创建的实例列表中，您可以查看已成功创建的伸缩组中的ECS实例信息。
说明您也可以登录ECS管理控制台，在左侧导航栏，选择后，选择地域为华北5（呼和浩特），查看已成功创建的伸缩组中的ECS实例信息。
单击伸缩规则与报警任务页签，在伸缩规则页签下，查看已成功创建的伸缩规则。
单击生命周期挂钩页签，查看已成功创建的生命周期挂钩。
步骤四：对TiDB集群中的角色进行扩缩容操作
本步骤以对TiDB集群中TiDB Servers角色进行扩缩容为例，TiDB集群中其他角色的扩缩容方法与其相同。
在左侧导航栏中，单击伸缩组管理。
在伸缩组列表中，找到TiDB Server角色归属的伸缩组，单击对应伸缩组名称/ID列下的伸缩组ID。
单击伸缩规则与报警任务页签。
在伸缩规则页签下，找到已成功创建的伸缩规则，单击对应操作列的修改。
关于如何修改伸缩规则，具体操作，请参见修改伸缩规则。例如：
扩容操作：例如，您需要将伸缩组实例数量由3台增加至4台，在修改伸缩规则页面的执行的操作参数后，选择增加1台。
缩容操作：例如，您需要将伸缩组实例数量由4台减少至3台，在修改伸缩规则页面的执行的操作参数后，选择减少1台。
伸缩规则修改完成后，单击确认。
单击伸缩规则对应操作列的执行。
单击伸缩活动页签，查看伸缩活动详情。
查看伸缩活动结果的具体说明如下：
扩容成功时，在伸缩活动列表下，您可以查看到变化后的总实例数量为4台。
缩容成功时，在伸缩活动列表下，您可以查看到变化后的总实例数量为3台。
说明如果扩缩容失败，请您在伸缩活动详情页查看失败原因并修改相关配置，然后再次执行伸缩规则。
再次登录并刷新TiDB Dashboard页面，查看TiDB集群的TiDB Server角色中是否新增或者移出ECS实例。
具体操作，请参见步骤二：登录TiDB Dashboard页面并查看TiDB集群。
如果伸缩组扩容成功时，您可以同时在TiDB集群的TiDB Servers角色中查看到实例的变化情况，即多增加1台实例且显示在线运行。
如果伸缩组缩容成功时，您可以在TiDB集群的TiDB Server角色中查看到实例的变化情况，即减少1台实例且显示无法访问。
