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
代码语言：javascript复制--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 /ob2.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
代码语言：javascript复制[root@octa soft]# cd /soft/
[root@octa soft]# tar -xvf ob-deploy.tar
[root@octa soft]# ls
ob-deploy ob-deploy.tar2.修改默认配置
代码语言：javascript复制[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）
