obd 全称是 OceanBase Deployer，是 OceanBase 社区版的命令行下自动化部署软件。 根据中控机器能否连接公网，提供两个安装方法：离线和在线。二选一。
通过obd进行自动部署时，选择一台服务器作为中控机进行部署obd软件，obd软件支持离线部署和在线部署两种方式，下面分别介绍：
obd服务器没有特殊的资源需求，我的obd服务器配置为内存16G/磁盘40G空间。
离线部署笔记本提前下载好 OBD 、 OBSERVER 和 OBPROXY 相关软件包。后上传到admin用户家目录下的soft文件夹

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.

在线安装
首先在中控机上部署 OBD 软件。如果中控机能上网，则可以直接添加 OceanBase 的仓库，使用 YUM 安装。
yum install -y yum-utils
yum-config-manager --add-repo https://mirrors.aliyun.com/oceanbase/OceanBase.repo
yum install -y ob-deploy
