说明

机器软硬件要求

  • 机器有足够的资源可以执行至少 2 个物理核心和 4GB 内存（官方推荐8g及以上）但是4g内存拿来学习使用也是可以，官方提供的试用的服务就是4g内存
  • Docker环境
  • 推荐使用1panel进行服务器的可视化管理和维护

指导文档

本次部署环境说明

  • 系统：armbian( debian-11.7)
  • cpu:Cortex-A55 4c
  • 内存：4G
  • 硬盘容量：32G

OceanBase单机部署（Docker）

一：拉取 OceanBase 数据库相关镜像

  • 拉取 OceanBase 数据库最新镜像,默认安装最新版，可在OceanBase镜像地址进行版本选择
    docker pull oceanbase/oceanbase-ce

二：启动 OceanBase 数据库实例

  • 启动 OceanBase 实例时，执行以下命令：
#根据当前容器部署最大规格实例
docker run -p 2881:2881 --name obstandalone -e MINI_MODE=0 -d oceanbase/oceanbase-ce
#部署 mini 的独立实例
docker run -p 2881:2881 --name obstandalone -e MINI_MODE=1 -d oceanbase/oceanbase-ce

  • 挂载数据卷版本

    docker run -d -p 2881:2881 -v $PWD/ob:/root/ob -v $PWD/obd:/root/.obd --name oceanbase oceanbase/oceanbase-ce
    • 注意：docker 镜像将数据保存到 /root/ob 目录默认。应同时绑定 /root/ob 和 /root/.obd。如果只绑定 /root/ob 目录，则无法启动新的 docker 镜像，因为 docker 镜像 oceanbase-ce 使用 obd 来管理数据库集群，而新的 docker 容器中没有关于数据库集群的信息

  • 启动预计需要 2~5 分钟。执行以下命令，如果返回 boot success!，则表示启动成功。

    • 需要耐心等待，因为初始化需要很多操作，需要一些时间，cpu干到100%是正常的现象
    • 着急的话建议执行命令，参考下面提供的完整日志信息进行查看
root@armbian:~# docker logs obstandalone | tail -1
boot success!

三：连接实例

  • oceanbase-ce 镜像安装了 OceanBase 数据库客户端 OBClient，并提供了默认连接脚本 ob-mysql
    # 可以通过 root 用户连接到 oceanbase，无需密码
docker exec -it obstandalone ob-mysql sys # 使用 root 用户登录集群的 sys 租户
docker exec -it obstandalone ob-mysql root # 使用 root 用户登录集群的 test 租户
docker exec -it obstandalone ob-mysql test # 使用 test 用户登录集群的 test 租户
  • 使用您本机的 OBClient 或者 MySQL 客户端连接实例
    obclient -uroot@sys -h127.1 -P2881
  • 连接成功
    root@armbian:~# mysql -uroot -h127.1 -P2881
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MySQL connection id is 3221487879

遇到报错：没有mysql客户端

  • 根据提示执行命令安装即可！
    root@armbian:~# mysql -uroot -h127.1 -P2881
Command 'mysql' not found, but can be installed with:
apt install mariadb-client-core-10.5
root@armbian:~# apt install mariadb-client-core-10.5

四：挂载数据卷

  • 如果想持久化容器的数据，可以在 docker 命令中使用 parameter 将数据保存在主机 os 中
  • 这里使用1panel提供的可视化管理进行操作
  1. 本地创建挂载的目录/home/OceanBase/ob和/home/OceanBase/bos
    /home/OceanBase
	|--ob
	|--obs
  2. 挂载数据卷
    在这里插入图片描述
  3. 然后确定重启镜像，可在1pane容器的日志中查看启动状态
