使用obd demo离线部署单副本集群
环境介绍：
- centos 7.6
- 可用内存不少于8G
- 安装目录空间不少于50G（默认安装在当前安装用户的家目录下）
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在线快速（默认使用远程仓库）部署oceanbase cluster的最新版本，集群名称是demo。
使用obd demo在线快速部署单副本集群，默认安装的组件：grafana、obproxy-ce、oceanbase-ce、obagent、prometheus，版本是当前最新版本。
下载需要的组件，使用obd demo离线快速部署单副本集群。
2. 下载oceanbase组件包：ob-deploy、obclient、oceanbase、obproxy，到/tmp/ob/目录
https://www.oceanbase.com/softwarecenter
3. 安装obd
[root]# rpm -ivh ob-deploy-2.0.0-10.el7.x86_64.rpm
4. 删除远程仓库（）
[root]# rm -fr /root/.obd/mirror/remote/OceanBase.repo
5. 将下载的组件报复制到本地仓库
[root]# obd mirror clone /tmp/ob/*.rpm
6. 查看本地镜像仓库中的组件信息
[root]# obd mirror list local

7. 使用本地镜像仓库部署指定安装组件：obclient、obproxy-ce、oceanbase-ce，报“No such install plugin for obclient-2.2.2”
[root]# obd demo -c obclient,obproxy-ce,oceanbase-ce
Package obclient-2.2.2-1.el7 is available.
