Oceanbase试用版部署安装(Linux 平台上部署)

一、部署概述

1.官方建议使用CentOS 6 或 CentOS 7，部署脚本只在这两个发行版上试验过。

2.资源要求

资源

描述

内存要求

至少为 OBServer 配置 8G 内存。

磁盘要求

需要为 OBServer 准备一个工作目录，这个目录所在的磁盘至少要有 20G 的剩余空间，并且磁盘使用率要低于 80%。

3.软件要求

软件

版本

Python

Python 2.7 及以上

二、部署前准备

部署一台8G内存，50G磁盘空间，单网卡（hostonly模式）的centos7的服务器。

1.前期配置

--查看内核 [root@octa ~]# uname -a Linux octa 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux [root@octa ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) --查看内存 [root@octa ~]# free -m total used free shared buff/cache available Mem: 7886 134 7643 8 109 7556 Swap: 5119 0 5119 --设置主机名 hostnamectl set-hostname obca --关闭防火墙 systemctl stop firewalld systemctl disable firewalld --关闭selinux vi /etc/selinux/config disabled --配置网络 nmcli con mod ens0p3 ipv4.address 192.168.56.100/24 ipv4.method manual autoconnect yes --新建目录 mkdir /soft mkdir /ob

2.下载试用版oceanbase安装包

在 OceanBase 官网顶部导航栏，选择 资源 > 下载， 进入资源下载页面。

单击 安装包下载，系统会跳转到 OceanBase 社区登录页面。

输入您的用户名和密码，进行登录。

如果您还未注册 OceanBase 社区账号，请按照提示完成注册，并登录。

在弹出的对话框中，勾选 我已阅读并遵守《OceanBase 软件试用许可协议》，然后单击 下载安装包。

OceanBase 试用版的安装介质开始下载，下载的安装介质中包含部署脚本（ob-deploy.tar）。

三、安装部署

1.解压安装包

[root@octa soft]# cd /soft/ [root@octa soft]# tar -xvf ob-deploy.tar [root@octa soft]# ls ob-deploy ob-deploy.tar

2.修改默认配置

[root@octa soft]# cd ob-deploy [root@octa ob-deploy]# ls admin config.py features.md init.sql install mysql plugin_dir tools b deploy.dockerfile h init_user_oracle.sql lib mysql_example README.md bin etc hap.py init_user.sql Makefile oracle_example sysbench --配置observer启动目录home = '/ob' [root@octa ob-deploy]# vi config.py [root@octa ob-deploy]# cat config.py load('obi,obt-patch,mini-mode,sample-db,sysbench') if not indocker(): home = '/ob' obs_cfg.update(mini_mode_cfg) obs_cfg.update(system_memory='5G', memory_limit='8G', datafile_size='10G') # 定义一个单server的ob集群，mysql端口号2881，rpc端口号2882 ob1 = OBI('127.0.0.1:2882:2881') # 定义另一个单server的ob集群，mysql端口号/rpc端口号由uid hash生成 ob2 = OBI('127.0.0.1') # 单个机器上起3个observer ob3 = OBI('127.0.0.1@[z1,z2,z3]', dev='lo', is_local=True)

3.初始化 OceanBase 实例（整个初始化过程大概需要一分钟时间）
