obd 全称为 OceanBase Deployer,是 OceanBase 数据库的 安装部署工具,可以通过 命令行部署或白屏界面部署 , 已成为集群与单机环境安装的 “标配利器”。按是否支持配置文件方式有可细分三种灵活部署模式: 可视化界面(obd web)配置操作、交互式命令(obd cluster deploy -i)向导式配置、配置文件(config.yaml) 批量部署, 将复杂配置流程标准化,降低集群部署难度。
其中,命令行支持编辑配置文件,可以更加灵活的进行配置调整,适用于需要深度了解 OceanBase 的用户,有一定的使用门槛;白屏界面配置简单,通过页面的引导配置即可完成集群部署,适用于需要快速体验,构建标准环境的用户。
在集群部署之外,obd 还提供了包管理器、压测软件、集群管理等常用的运维能力,更好地支持用户体验使用 OceanBase 分布式数据库。
补充:
配置文件(config.yaml) 本质也是属于命令行部署的一种。 obd cluster deploy -i 属于命令行形式,本质属于定制化部署的一种,相比obd demo/obd perf
安装 obd 的方法有3种,分别是通过 OceanBase All in One 安装、使用 RPM 安装以及使用源码安装 ,其中RPM 安装方式部署,需要考虑所用机器是否可以连接外部网络,分为 在线安装 和 离线安装 两种 安装方法。需要注意的是,通过 RPM 包安装时仅安装 obd,当机器可以连接外部网络时,obd 会访问远程镜像源获取部署集群所需安装包;当机器无法连接网络时,成功安装 obd 后,您还需手动配置 obd 的本地镜像库。
本文是基于RPM 方式离线部署OBD。

在“安装工具”模块中单机右上角向下的箭头,选择V3.5.0,根据部署环境选择对应的安装介质,本文环境是Centos7.6 2C6GB。
注意:选择对应的版本,OBD V3.5.0版本支持el7和el8

将下载文件 ob-deploy-3.5.0-5.el7.x86_64.rpm 上传至/opt目录下
obd 提供了部署集群所需的配置文件示例,可根据自身机器资源情况进行修改。

说明:
将安装包添加到 obd 的本地镜像库的主要目的是为了确保在离线环境中可以顺利地进行后续的组件升级或部署操作。当obd处于离线环境时,它无法从外部网络下载所需的RPM包来完成升级或其他操作,因此需要预先将这些RPM包添加到obd的本地镜像库中。这样,当执行如升级、部署等命令时,obd可以直接从本地镜像库中获取所需的RPM包,而不需要依赖于外部网络连接。此外,这样做也有助于提高操作的安全性和可控性,因为所有使用的软件包都可以事先经过审查和测试。
安装 obd 后,可执行
obd demo
或
obd pref
命令快速部署本地单节点 OceanBase 数据库。
服务器为 x86 架构,服务器需支持 AVX 指令集,可执行
lscpu | grep Flags | grep avx
命令查看是否支持 AVX 指令集。
仅在所用服务器为 x86 架构时有此限制,若您使用其他架构服务器,可忽略本小节内容。
返回结果如下所示,若输出中存在
avx
字段,说明该服务器支持 AVX 指令;若输出中不存在
avx
字段,则说明该服务器不支持 AVX 指令,您需更换为支持 AVX 的服务器。

字段,则说明该服务器不支持 AVX 指令,您需更换为支持 AVX 的服务器。
查看服务器的可用内存是否满足官网《OceanBase 数据库》文档 软硬件要求 中的可用内存要求。
[root@localhost opt]# free -g
返回结果如下所示,
available
列所对应的
Mem
值为 5,满足可用内存要求。
[root@localhost opt]# free -g total used free shared buff/cache available Mem: 5 0 4 0 0 5 Swap: 1 0 1
若查看结果显示的内存不满足部署 OceanBase 数据库的内存要求,可以考虑执行如下命令清空 Linux 缓存:PageCache、dentries 和 inodes。
sudo sysctl -w vm.drop_caches=3 #或 sudo echo 3 > /proc/sys/vm/drop_caches
运行以下命令,查看操作系统信息。操作系统需要满足官网《OceanBase 数据库》文档 软硬件要求 中要求。
[root@localhost opt]# cat /etc/os-release
返回结果如下所示,可以看出所用操作系统为
CentOS Linux
(
NAME
字段),版本为
7
(
VERSION
字段)。
[root@localhost opt]# cat /etc/os-release NAME="CentOS Linux" VERSION="7 (Core)" ID="centos" ID_LIKE="rhel fedora" VERSION_ID="7" PRETTY_NAME="CentOS Linux 7 (Core)" ANSI_COLOR="0;31" CPE_NAME="cpe:/o:centos:centos:7" HOME_URL="https://www.centos.org/" BUG_REPORT_URL="https://bugs.centos.org/" CENTOS_MANTISBT_PROJECT="CentOS-7" CENTOS_MANTISBT_PROJECT_VERSION="7" REDHAT_SUPPORT_PRODUCT="centos" REDHAT_SUPPORT_PRODUCT_VERSION="7"
OceanBase 数据库目前有提供 X86 版(el7 和 el8)和 ARM 版(el7 和 el8)的安装包。部署之前,请查看服务器的内核以便获取正确的安装包。
运行以下命令,查看内核信息:
[root@localhost opt]# uname -a
返回结果如下所示,机器的内核为
3.10.0-1160
,其操作系统版本为
el7
,CPU 架构为
x86_64
,因此,需要使用后缀为
el7.x86_64
的安装包,例如
oceanbase-ce-4.3.5.3-103000092025080818.el7.x86_64.rpm
。
[root@localhost opt]# uname -a Linux localhost.localdomain 3.10.0-1160.el7.x86_64 #1 SMP Mon Oct 19 16:18:59 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux

部署 OceanBase 数据库社区版需要规划以下三个目录,同时要求文件系统类型为 XFS 或 EXT4。
--安装目录为 /data/base,日志保存目录为 /data/log1 ,数据保存目录为 /data/1
mkdir -p /data/{base,log1,1}
不推荐在 root 用户下部署 OceanBase 数据库,建议创建其他用户用于部署,推荐使用 admin 用户。用户需为数据库相关目录的所有者。
obd 支持 通过主机命令组对主机和对应用户执行初始化操作 ,可选择 通过 obd 命令进行上述配置 配置,也可选择 手动配置。推荐通过 obd 命令配置 。
obd host user init -u admin --host=192.168.40.110 -p admin --参数说明 --host=192.168.40.110:待创建用户的主机 IP(--host) -u:待创建并初始化的用户 -p:用户密码 --赋予安装目录权限 chown -R admin:admin /data/base chmod -R 775 /data/base
使用
admin
用户登录
192.168.40.110
机器并执行初始化操作。
使用该命令会自动修改部署 OceanBase 数据库时建议修改的
内核参数、关闭防火墙和 SELinux 功能、修改
/data/1
和
/data/log1
目录属主(如存在对应目录),并安装 network 组件
。

查看结果显示的内存不满足部署 OceanBase 数据库的内存要求,执行如下命令清空 Linux 缓存:PageCache、dentries 和 inodes。
sudo sysctl -w vm.drop_caches=3 #或 sudo echo 3 > /proc/sys/vm/drop_caches
再次安装依然报错: [ERROR] The machine's minimum memory cannot be less than min_value (6G). Please try again.
[admin@localhost ~]$ free -g total used free shared buff/cache available Mem: 7 0 7 0 0 4 Swap: 1 0 1
临时解决办法将内存从8G扩到10G,注意官方文档上写的低配6G是指可用内存而不是服务器内存或free值,而是指available值。
[root@localhost ~]# free -g total used free shared buff/cache available Mem: 9 0 9 0 0 6 Swap: 1 0 1

注意:若不安装连接 OceanBase 数据库会提示obclient命令不存在。
使用上述部署结果中,输出的连接串连接 OceanBase 数据库的 sys 租户
obclient -h192.168.40.110 -P2881 -uroot@sys -p'WgnHVW73cV7OGY4QDABT' -Doceanbase -A
输出如下:

输出如下:

至此,通过OBD离线部署OceanBase部署完成。
OBD离线部署很便捷,仅通过一个轻便的rpm包即可完成部署。而通过OBD离线部署OceanBase数据库前期需要注意硬件配置尤其是内存方面需要注意最低内存是指available值,非total和free值。
