OBD 是OceanBase的命令行部署工具在 obd V2.5.0 版本之前其主要功能主要是部署各类组件例如 oceanbase-ce,obproxy-ce,obagent 等。然而它并不支持组件的变更操作以及组件内部的扩缩容调整。具体来说
1、若用户希望使用 obd 来扩容 oceanbase-ce必须手动将新增节点的信息复制到对应组件的精确位置这一过程繁琐且易出错因此备受用户诟病。
2、obd 不具备删除通过其部署的组件的功能。
3、可以通过创建新的 deploy_name 来添加新组件但新部署的组件配置无法与其他组件的配置合并统一进行管理。
因此很开心在 OBD V2.5.0 开始支持
•组件内扩容⽀持除了 ocp-server 以外的全部组件扩容
•组件变更⽀持添加和删除组件 组件内扩容体验
将 observer 从单节点扩容为 1-1-1的集群
扩容前配置

新增 obproxy-ce 组件
1、准备新增组件的配置文件
cat obproxy1.yaml
obproxy-ce:package_hash: 0aed4b782120e4248b749f67be3d2cc82cdcb70ddepends:- oceanbase-ceservers:- 172.24.255.94global:listen_port: 22883prometheus_listen_port: 22884home_path: /home/admin/obproxy421enable_cluster_checkout: falseskip_proxy_sys_private_check: trueenable_strict_kernel_release: falseobproxy_sys_password: aaAA11__observer_sys_password: aaAA11__
2、执行添加组件操作
obd cluster component add ob421 -c obproxy1.yaml
Get local repositories and plugins ok
Cluster status check ok
Get added repositories and plugins ok

3、添加组件后确认
确认新组件 (obproxy-ce) 已添加成功且可以和已有的组件oceanbase-ce) 一起管理
obd cluster display ob421

4、obproxy 组件内扩容
上面的操作执行后只有一个 obproxy 节点这里再次体验一下通过 obd 来扩容组件obprxoy-ce) 的节点
cat obproxy2.yaml
obproxy-ce:servers:- 172.24.255.95
obd cluster scale_out ob421 -c obproxy2.yaml
非常赞扩容就是这么简单。

删除 obproxy-ce 组件
obd cluster component del ob421 obproxy-ce 注意事项
1、组件内扩容的配置文件里不允许出现 depends,global 对应的配置否则会出现类似的报错 [ERROR] OBD-1023: Failed to merge config: depends is not allowed to be set
2、新增组件时 deploy_name 需要填写已有的 deploy_name 比如ob421填写不存在的名字会有如下类似的报错 [ERROR] No such deploy: ob421_obproxy. PS: 在 obd250 之前的版本新增组件是需要填写一个不存在 deploy_name 名字。
3、obd 组件内扩容 oceanbase-ce 后不会自动扩容租户的 unit_num需要手动执行 sql 命令行进行扩容。
4、不支持组件内的缩容操作。
