安装 OBD 软件（离线）
首先在中控机上部署 OBD 软件。如果中控机不能上网，则需要提前下载好 OBD 、 OBSERVER 和 OBPROXY 相关软件包。
- 下载相关软件包
软件包地址请根据 OS 版本自行选择。
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/ob-deploy-1.1.0-1.el8.x86_64.rpm
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/oceanbase-ce-3.1.0-3.el8.x86_64.rpm
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/oceanbase-ce-libs-3.1.0-3.el8.x86_64.rpm
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/obclient-2.0.0-2.el8.x86_64.rpm
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/libobclient-2.0.0-2.el8.x86_64.rpm
wget https://mirrors.aliyun.com/oceanbase/community/stable/el/8/x86_64/obproxy-3.1.0-1.el8.x86_64.rpm
将上面文件都复制到中控机上临时目录。
- 离线安装 OBD
[admin@obce00 obd]$ sudo rpm -ivh ob-deploy-1.1.0-1.el8.x86_64.rpm
[sudo] password for admin:

Installation of obd finished successfully
Please source /etc/profile.d/obd.sh to enable it
[admin@obce00 obd]$ source /etc/profile.d/obd.sh
[admin@obce00 obd]$ which obd
/usr/bin/obd
ob-deploy 软件默认安装在 /usr/obd 下。不同版本可能有点变化。可以通过下面命令查看位置。
rpm -ql `rpm -qa|grep ob-deploy`
但是 OBD 工作的文件都在当前用户 HOME 目录下：~/.obd/
[admin@obce00 ~]$ tree ~/.obd -L 1
/home/admin/.obd
├── cluster
├── log
├── mirror
├── obd.conf
├── plugins
├── repository
└── version
5 directories, 2 files
命令 obd 使用帮助，可以直接用 -h 查看。
obd -h
输出：
[admin@obce00 ~]$ obd -h
Usage: obd <command> [options]
Available commands:
cluster Deploy and manage a cluster.
mirror Manage a component repository for OBD.
repo Manage local repository for OBD.
test Run test for a running deploy deployment.
update Update OBD.
Options:
--version show program's version number and exit
-h, --help Show help and exit.
-v, --verbose Activate verbose output.
- 将软件包加到离线仓库
首先要删除远程仓库，使用下面命令。 注意：下面命令要在部署运行 OBD 的操作系统用户下操作。这里是用户 admin 。
/bin/rm -rf ~/.obd/mirror/remote/OceanBase.repo
然后将前面的软件包都复制到本地仓库，使用下面命令。
obd mirror clone /tmp/obd/*.rpm
查看仓库的 RPM 列表。
obd mirror list local
输出：
[admin@obce00 ~]$ obd mirror list local

安装 OBD 软件（在线）
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
查看一下 OceanBase.repo 内容。
cat /etc/yum.repos.d/OceanBase.repo
输出：
