OBD黑屏部署商业版OB集群

2024年 6月 19日 80.1k 0

一、概述

OBD 是 OB 官方提出的部署工具,极大简化了 OB 单机及集群的部署过程。在此之前,OBD 支持对社区版 OB 的一键部署,但细细想来 OBD 是否支持商业化 OB 的部署呢?随着自己测试后发现想法是可行的,于是就斥“巨资”购买了三台 AliyunECS 来进行部署测试,最后就有如下商业版 OB 集群部署的踩坑文档分享。

二、部署准备

开发机资源 cpu与内存 存储大小
阿里云AY1 2C8G 40G
阿里云AY2 2C8G 40G
阿里云AY3 2C8G 40G
资源包 版本
OceanBase商业版 4.2.2.0
OB-Deploy 2.4.1(2.5以上不支持商业版,2.4.1可兼容431版本的OB,预计3.0开始支持商业版)
OBProxy 4.2.3.0
OBClient 2.2.6

注意⚠️:本篇文档部署的是企业版OceanBase,并非社区版

前置条件:为了方便OBD远程部署,需要将集群内开发机的SSH登录用户名和密码改为一样的,如:

username:root
password:xxxxx

一台机器上先准备如下四个文件(如下载到AY1上),点击前往RPM网站搜索下载

三、部署流程

解压 ob-deploy 文件

rpm -ivh ob-depoly.xxxxxx.rpm

然后将所有的 rpm 加入 OBD 的镜像当中

rpm mirror remote disable
rpm mirror clone *.rpm
rpm mirror list local

查看是否添加成功

进入 /usr/obd/example 目录下,编辑 mini-distribute-withe-obproxy-example.yaml 文件

编辑好文件后我们就可以部署 obcluster 这个集群了

obd cluster deploy obcluster -c mini-distributed-with-obproxy-example.yaml

此时启动 obcluster 可能会报错

what❓

针对此问题有两种解决方法

方法一

  • 如果对安全检查不是很在意,且仅仅是简单测试的话可以试试该方法,如下直接删除安全检查脚本即可(结果可能不稳定,且也需要每台机器运行一遍,故不推荐该方法)
rm -rf ~/.obd/plugins/oceanbase/*/start_check.py

方法二

  • 比较推荐的方法,只需要每台机器执行一遍如下命令
echo -e "* soft nproc 120000\n* hard nproc 120000" >> /etc/security/limits.d/20-nproc.conf
source /etc/profile

本篇文档使用方法二进行部署,随后重新执行启动集群命令

obd cluster start obcluster

按照提示登录 OB 即可检验是否拉起分布式环境

💡OBD 全程部署需要等待的时间大约为3分钟。若您想获取源码及更多详情,请访问我们的 GitHub 仓库:https://github.com/oceanbase/obdeploy。
