1. 什么是obd？
odb是oceanbase社区版部署工具oceanbase deployer的简称，通过obd可以快速完成oceanbase clusterr的部署。
不传入配置文件的情况下，在单机通过执行obd demo可以快速部署oceanbase cluster的最新版本，集群名称是demo。
使用obd demo快速部署安装的是最新的版本，默认安装的组件：grafana、obproxy-ce、oceanbase-ce、obagent、prometheus。
2. 下载obd
https://www.oceanbase.com/softwarecenter
3. 安装obd
[root]# rpm -ivh ob-deploy-2.0.0-10.el7.x86_64.rpm
4. 执行obd demo快速部署
[root]# obd demo或者
[root]# obd demo -c oceanbase-ce,obproxy-ce,obagent,prometheus,grafana --home_path=/root/
