简介: 「更易用的OceanBase」| OceanBase Deployer初体验

一、ODB

1. 什么是OBD?

OBD 全称为 OceanBase Deployer,是 OceanBase 开源软件的安装部署工具。OBD 同时也是包管理器,可以用来管理 OceanBase 所有的开源软件。

二、安装OBD

1. 安装yum-utils

[root@oceanbase1 ~]# sudo yum install -y yum-utils
Loaded plugins: fastestmirror, langpacks
adding repo from: https://mirrors.aliyun.com/oceanbase/OceanBase.repo
grabbing file https://mirrors.aliyun.com/oceanbase/OceanBase.repo to /etc/yum.re                              pos.d/OceanBase.repo
repo saved to /etc/yum.repos.d/OceanBase.repo
[root@oceanbase1 ~]# sudo yum install -y ob-deploy

Complete!

2. 下载repo

[root@oceanbase1 ~]# sudo yum-config-manager --add-repo https://mirrors.aliyun.c                              om/oceanbase/OceanBase.repo

repo saved to /etc/yum.repos.d/OceanBase.repo
[root@oceanbase1 ~]# cat /etc/yum.repos.d/OceanBase.repo
# OceanBase.repo
[oceanbase.community.stable]

gpgcheck=1
gpgkey=http://mirrors.aliyun.com/oceanbase/RPM-GPG-KEY-OceanBase

毕竟是阿里出来的,必然依托阿里云

3. 安装ob-deploy

  • rpm 安装

5. ob-deploy

看看ob-deploy都有什么

从文件内容可以推测出一些支持或待支持的功能

  • sysbench,tpcc,tpcds,tpch测试
  • yaml是各种配置文件
  • mirror存放的是repo文件
  • mysqltest mysql的一些测试

  • 这里不知道为什么官方文档给的端口是2883,实际是2881

四、总结

  • 虽然文档有一些小出入,但是整体安装来看还算顺畅,坑不多。
  • 居然没有自带客户端,有懂的麻烦帮忙解答一下。
  • 从obd文件内容看是封装了不少东西的,期待后续的测试。

再次了解kafka
Kafka通过offset机制解决消息重复消费问题,支持手动提交偏移量及唯一ID去重。它保证分区内的消息顺序消费,结合集群、副本与重平衡实现高可用。高性能设计包括顺序读写、分区、页缓存、零拷贝等。数据清理依赖保留时间或大小策略,点对点和发布订阅模式则通过消费者组实现。
