OceanBase数据库Docker****部署文档
本文主要是使用docker容器使用oceanbase镜像部署一个单节点集群，供学习使用。其中也有一些再部署过程中出现的一些问题报错，我也给出了一些问题分析和解决办法。
一、部署准备
1、主机版本信息及配置：
Windows 10, 64-bit, 8C,16G
2、VMware版本信息：
VMware® Workstation 12 Pro 12.0.0 build-2985596
3、CentOS-7版本信息及配置：CentOS-7-x86_64-DVD-2009
虚拟机配置 Cpu 8核,内存16G，硬盘 20G
注：docker安装简单切勿用于生产
二、部署过程
1、配置一下yum
wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo
yum makecache
2、安装一下docker
yum -y install docker
3 、查看docker安装列表
yum list installed | grep docker
[root@localhost yum.repos.d]# yum list installed | grep docker
docker.x86_64 2:1.13.1-208.git7d71120.el7_9 @extras
docker-client.x86_64 2:1.13.1-208.git7d71120.el7_9 @extras
docker-common.x86_64 2:1.13.1-208.git7d71120.el7_9 @extras 安装成功
4、 启动docker容器
service docker start
5、查看docker是否启动（active为启动状态）
service docker status
[root@localhost yum.repos.d]# service docker status
Redirecting to /bin/systemctl status docker.service
● docker.service - Docker Application Container Engine
Loaded: loaded (/usr/lib/systemd/system/docker.service; disabled; vendor preset: disabled)
Active: active (running) since 六 2021-12-11 10:08:13 CST; 7s ago

Main PID: 20796 (dockerd-current)
Tasks: 28
CGroup: /system.slice/docker.service

└─20807 /usr/bin/docker-containerd-current -l unix:///var/run/docker/.
6、搜索oceanbase镜像
docker search oceanbase
[root@localhost yum.repos.d]# docker search oceanbase

docker.io docker.io/superbigfu/oceanbase 0
7、安装 docker
docker pull oceanbase/obce-mini
8、运行docker
docker run -p 2881:2881 --name oceanbase-mini -d -e OB_HOME_PATH="/root/obce/" -e OB_TENANT_NAME="obmysql" oceanbase/obce-mini
9、查看运行日志
[root@localhost yum.repos.d]# docker logs oceanbase-mini
generate boot.yaml ...
create boot dirs and deploy ob cluster ...
Package oceanbase-ce-3.1.0 is available.
install oceanbase-ce-3.1.0 for local ok
+-----------------------------------------------------------------------------+
| Packages |
+--------------+---------+---------+------------------------------------------+
| Repository | Version | Release | Md5 |
+--------------+---------+---------+------------------------------------------+
| oceanbase-ce | 3.1.0 | 2.el7 | afd11d52f83eef4b456d77969fde620c4bfba85e |
+--------------+---------+---------+------------------------------------------+
Open ssh connection ok**
10、进入oceanbase，并启动集群：
[root@localhost yum.repos.d]# docker exec -it oceanbase-mini bash
[root@92a08310b8f3 /]# obd cluster start mini-ce
Get local repositories and plugins ok
Open ssh connection ok
Cluster status check ok
Deploy "mini-ce" is running
11、进入数据库（初次完成不需要输入密码）
obclient -h 127.0.0.1 -P 2881 -uroot -p -c -A
12、查看当前资源规格及资源池配置（默认是有一个obmysql）
select unit_config_id, name from __all_unit_config;
select resource_pool_id, name from __all_resource_pool;
MySQL [oceanbase]> select tenant_id,tenant_name,max_cpu,min_cpu,max_memory/1024/1024/1024 from v$unit;
+-----------+-------------+---------+---------+---------------------------+
| tenant_id | tenant_name | max_cpu | min_cpu | max_memory/1024/1024/1024 |
+-----------+-------------+---------+---------+---------------------------+
| 1 | sys | 5 | 2.5 | 1.199999999255 |
| 1001 | obmysql | 9 | 9 | 2.500000000000 |
13、利用系统默认的用户登录（系统给的没有密码）
obclient -h 127.0.0.1 -P 2881 -uroot@obmysql -p -c -A
obclient -h 127.0.0.1 -P 2883 -u root@obmysql -p -c -A oceanbase
14、创建一个单元资源（可选）可跳过
create resource unit my_unit1 max_cpu=1, max_memory='1g', max_iops=128, max_disk_size='5g', max_session_num=64, min_cpu=1, min_memory='1g', min_iops=128;
15、资源池配置（可选）可跳过
create resource pool my_pool1 unit='my_unit1', unit_num=1, zone_list=('zone1');
16、创建一个租户
create tenant my_tenant1 resource_pool_list=('obmysql');
17、创建数据表
create table user1(id int(4) primary key, name varchar(20));
18、创建内容
insert into user1(id, name) values(1, '张三');
insert into user1(id, name) values(2, '李四');
MySQL [test]> select * from user1;
+----+--------+
| id | name |
+----+--------+
| 1 | 张三 |
| 2 | 李四 |
+----+--------+
2 rows in set (0.002 sec)
