前提条件

官方给出硬件条件需要满足以下要求

Red Hat Enterprise Linux 8 64 位

下载链接:https://pan.baidu.com/s/1rZ39xJFhk0HdmC4wEJcxvg

提取码:c01x

本文操作系为:CentOS7

一、 OceanBase 集群部署规划

1、创建用户

OceanBase数据库可以在任何用户下运行。该软件包的默认解压目录位于 /home/admin/ 。为了安全起见,我们将其安装在 admin 用户下。

  1. 使用以下命令新建用户:
powershell 复制代码
 useradd admin
  1. 给用户admin赋予root权限
    使用以下命令进入相关配置文件并进行修改,示例如下图:
powershell 复制代码
  vi /etc/sudoers

2、规划目录

参数或目录 备注
observer部署/启动目录 /home/admin/oceanbase RPM包自动创建
observer数据总目录 /home/admin/oceanbase/store/obdemo 手动创建
observer数据文件实际目录 /data/obdemo/sstable 手动创建,通过软链接映射到数据总目录下
observer事务日志实际目录 /redo/obdemo/{clog,slog,ilog} 手动创建,通过软链接映射到数据总目录下
observer参数文件目录 /home/admin/oceanbase/etc 启动时在启动目录自动创建或自动读取
observer运行日志目录 /home/admin/oceanbase/log 启动时在启动目录自动创建

创建命令如下:

powershell 复制代码
 sudo mkdir -p /home/admin/oceanbase/store/obdemo /data/obdemo/sstable /redo/obdemo/{clog,slog,ilog}
powershell 复制代码
sudo ln -s /data/obdemo/sstable /home/admin/oceanbase/store/obdemo/sstable
powershell 复制代码
sudo ln -s /redo/obdemo/slog /home/admin/oceanbase/store/obdemo/slog
powershell 复制代码
 sudo ln -s /redo/obdemo/clog /home/admin/oceanbase/store/obdemo/clog
powershell 复制代码
 sudo ln -s /redo/obdemo/ilog /home/admin/oceanbase/store/obdemo/ilog
powershell 复制代码
echo 'export LD_LIBRARY_PATH=\SLD_LIBRARY_PAT:~/oceanbase/lib'>> ~/.bash_profile

设置文件所有者

xml 复制代码
sudo chown -R admin.admin /data /redo

查看目录结构:

powershell 复制代码
tree oceanbase/ /data/ /redo/

二、安装OceanBase环境

1、 方案一:若机器能联网执行如下命令在线下载并安装 all-in-one 安装包

powershell 复制代码
bash -c "$(curl -s https://obbusiness-private.oss-cn-shanghai.aliyuncs.com/download-center/opensource/oceanbase-all-in-one/installer.sh)"

执行完成后显示 Install Finished

然后在执行如下命令设置环境变量

powershell 复制代码
source ~/.oceanbase-all-in-one/bin/env.sh

2、 方案二:若机器不能联网需要在官网下载 all-in-one安装包,步骤如下:

(1)进入https://open.oceanbase.com/quickStart下载

(2)上传至虚拟机适当位置(这里我使用的是ssh客户端)

(3)进入其存放目录进行解压并安装

解压命令如下:

powershell 复制代码
tar -xzf oceanbase-all-in-one-*.tar.gz

解压后进入其bin目录下:

powershell 复制代码
 cd oceanbase-all-in-one/bin/

执行 ./install.sh进行安装

安装成功后执行source ~/.oceanbase-all-in-one/bin/env.sh,安装环境

示例如下:

bash 复制代码
[admin@localhost ~]$ ls
mini-single-with-obproxy-example.yaml  oceanbase  oceanbase-all-in-one-4.2.1.0-100120231013145059.el7.x86_64.tar.gz

(4)确认OBD是否安装成功

三、OBD部署单节点集群

1、编辑 OBD 配置文件

(1)部署单节点 observer 和 obproxy 进程,需要在官网下载配置文件
https://github.com/oceanbase/obdeploy/blob/master/example/mini-single-with-obproxy-example.yaml

(2)按照自己的设置编辑配置文件

  1. 部署集群
    使用如下命令部署集群
xml 复制代码
obd cluster deploy obcluster -c single-with-obproxy.yaml

报上图中所示错误原因:配置文件中的 user 用户(未填的情况下默认为当前用户)没有对应目录的写权限。可修改配置文件解决。

待其执行结束如下图所示:

  1. 部署结果
    使用命令 obd cluster list 查看部署状态
  2. 启动和初始化集群
xml 复制代码
 obd cluster stop obcluster
