一、前言

1.1 本次实践介绍

本次部署OceanBase 4.1社区版采用的是使docker单机快速部署方式，使用的是dockerhub中oceanbase/oceanbase-ce镜像，版本为4.1.0.0版本。该镜像仅供学习或测试使用，可以快速部署一个MINI_MODE OceanBase数据库实例，极大的提高了部署速度，方便快捷。

1.2 本次实践目的

1.本次实践环境为个人测试环境，生产环境请根据官方文档指导部署；
2.本次OceanBase 4.1社区版部署为docker单机快速部署方式；
3.体验OceanBase 4.1社区版的部署及基本使用；

二、准备环境资源

2.1 部署前需准备工作

确保机器已经部署docker环境
Docker服务状态运行正常
宿主机2881端口没有被占用
防火墙已放行2881端口
确保宿主机内存大于8G
宿主机cpu内核总数大于2
宿主机磁盘空间大于54G

2.2 本地环境规划

本次实践的个人环境规划如下，已经部署好docker环境，使用的是一台在PVE虚拟化平台的虚拟机作为实践环境。

hostname	IP地址	docker版本	操作系统版本	CPU核数	内存	硬盘	虚拟化平台	服务器类型	OceanBase版本
docker	192.168.3.127	23.0.5	centos 7.6	6	12G	500G	PVE虚拟化平台	虚拟机	OceanBase 4.1社区版

三、部署Docker环境

3.1 安装Docker

执行以下两条命令，使用docker快速安装脚本，一键快速部署docker。

curl -fsSL get.docker.com -o get-docker.sh
sh get-docker.sh --mirror Aliyun

启动Docker服务，并设置开机自启。

systemctl --now enbale docker

3.2 配置Docker镜像加速

修改/etc/docker/daemon.json文件，配置Docker镜像加速。

echo '{ "registry-mirrors": ["https://sp4mg57h.mirror.aliyuncs.com"] }'   > /etc/docker/daemon.json

3.3 开启路由转发

开启路由转发，并重启网络服务。

[root@docker ~]# echo "net.ipv4.ip_forward=1" >>  /etc/sysctl.conf
[root@docker ~]#  systemctl restart network
[root@docker ~]#  sysctl net.ipv4.ip_forward
net.ipv4.ip_forward = 1

3.4 重启Docker服务

重启Docker服务。

systemctl daemon-reload  && systemctl restart docker

四、检查本地Docker环境

4.1 检查docker版本

检查本机安装的docker版本

[root@docker ~]# docker -v 
Docker version 23.0.5, build bc4487a

4.2 检查Docker服务

检查本机的docker服务状态

[root@docker ~]# systemctl status docker
● docker.service - Docker Application Container EngineLoaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)Active: active (running) since Thu 2023-04-27 15:40:54 CST; 24min agoDocs: https://docs.docker.comMain PID: 5092 (dockerd)Tasks: 12Memory: 549.2MCGroup: /system.slice/docker.service└─5092 /usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock

4.3 检查磁盘大小

检查docker宿主机的磁盘大小，确保满足部署要求。

[root@docker ~]# df -h 
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda6       360G   26G  334G   8% /

4.4 检查内存大小

检查docker宿主机的内存大小，确保满足部署要求。

[root@docker ~]# free -mtotal        used        free      shared  buff/cache   available
Mem:          11852        5537         345           8        5970        5878
Swap:          8191           7        8184

4.5 检查cpu核数

检查cpu的核心数，确保大于2核。

[root@docker ~]# cat /proc/cpuinfo| grep "cpu cores"| uniq
cpu cores	: 6

4.6 检查2881端口

检查2881端口是否被占用，确保没有服务占用2881端口。

ss -tunlp |grep 2881

检查防火墙是否放行2881端口

[root@docker ~]# firewall-cmd --list-ports 
2881/tcp

如果防火墙未放行2881端口，则执行以下放行命令：

[root@docker ~]# firewall-cmd --permanent --add-port=2881/tcp
success
[root@docker ~]# firewall-cmd --reload 
success

五、部署OceanBase 4.1社区版

5.1 下载OceanBase 4.1镜像

在dockerhub下载oceanbase/oceanbase-ce:4.1.0.0容器镜像

[root@docker ~]# docker pull oceanbase/oceanbase-ce:4.1.0.0

5.2 创建OceanBase容器

创建容器挂载目录/data/ob.

mkdir -p /data/ob/  &&  mkdir -p /data/obd/

在本地系统环境，创建一个OceanBase容器。

docker run -d -p 2881:2881 -v /data/ob:/root/ob -v /data/obd:/root/.obd --name oceanbase oceanbase/oceanbase-ce:4.1.0.0

5.3 检查OceanBase容器状态

检查OceanBase容器状态，查看容器是否正常启动。

[root@docker data]# docker ps
CONTAINER ID   IMAGE                            COMMAND              CREATED         STATUS         PORTS                                       NAMES

七、在OceanBase数据库创建数据表

7.1 使用mysql客户端连接OceanBase

使用mysql客户端远程连接OceanBase数据库

[root@server ~]# mysql -h 192.168.3.127  -P 2881 -u admin@test -padmin123  -Ac --prompt "OceanBase(\u@\d)> " 
Warning: Using a password on the command line interface can be insecure.

+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| oceanbase          |
| test               |
| wordpress          |
| wordpress_db       |
+--------------------+
6 rows in set (0.37 sec)OceanBase(admin@(none))>

7.2 创建数据库

在OceanBase内创建一个数据库school

OceanBase(admin@(none))>  create database school;
Query OK, 1 row affected (0.44 sec)OceanBase(admin@(none))> show databases;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| oceanbase          |
| school             |
| test               |
| wordpress          |
| wordpress_db       |
+--------------------+
7 rows in set (0.35 sec)OceanBase(admin@(none))>

7.3 进入数据库内

进入新创建的school数据库内

OceanBase(admin@(none))> use school;
Database changed
OceanBase(admin@school)> show tables;
Empty set (0.00 sec)OceanBase(admin@school)>

7.4 新建数据表

创建一个空数据表

 CREATE TABLE IF NOT EXISTS `student`(`id` INT UNSIGNED AUTO_INCREMENT,`name` VARCHAR(100) NOT NULL,`gender` TINYINT NOT NULL,`age` INT UNSIGNED,`class` INT UNSIGNED,`score` INT UNSIGNED,PRIMARY KEY ( `id` ))ENGINE=InnoDB DEFAULT CHARSET=utf8;

在这里插入图片描述

7.5 写入数据

向数据表student写入数据。


OceanBase(admin@school)> insert into student ( name, gender, age, class,  score ) values ( "李萌萌", "0", "17", "3", "98" );
Query OK, 1 row affected (1.30 sec)OceanBase(admin@school)> insert into student ( name, gender, age, class,  score ) values ( "王依依", "0", "14", "2", "68" );
Query OK, 1 row affected (0.57 sec)OceanBase(admin@school)> insert into student ( name, gender, age, class,  score ) values ( "张强", "1", "17", "3", "78" );
Query OK, 1 row affected (0.21 sec)

7.6 查看数据表内容

查看数据表内容
