【Database-06】Centos 9 安装docker版的Oceanbase
1、安装docker
1.1、卸载旧版本
旧版本的 Docker 被称为docker或docker-engine。如果安装了这些，卸载它们以及相关的依赖项。
yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine
yum如果报告没有安装这些软件包，那也没关系。
/var/lib/docker/ 的内容，包括图像、容器、卷和网络，将被保留。 Docker 引擎包现在称为 docker-ce。
[root@localhost /]# yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-engine

[root@localhost /]#
1.2、安装方法
您可以根据需要以不同的方式安装 Docker Engine：
大多数用户 设置 Docker 的存储库并从中安装，以简化安装和升级任务。这是推荐的方法。
一些用户下载 RPM 包并 手动安装并完全手动管理升级。这在诸如在无法访问 Internet 的气隙系统上安装 Docker 等情况下非常有用。
在测试和开发环境中，一些用户选择使用自动化 的便捷脚本来安装 Docker。
1.3、使用存储库安装
在新主机上首次安装 Docker Engine 之前，您需要设置 Docker 存储库。之后，您可以从存储库安装和更新 Docker。
1.3.1、设置存储库
安装yum-utils包（提供yum-config-manager 实用程序）并设置存储库。
yum install -y yum-utilsyum-config-manager \--add-repo \https://download.docker.com/linux/centos/docker-ce.repo
[root@localhost /]# yum install -y yum-utils

1.3.2.1、安装最新版本的 Docker Engine、containerd 和 Docker Compose
安装最新版本的 Docker Engine、containerd 和 Docker Compose 或转到下一步安装特定版本：
yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

此命令安装 Docker，但不会启动 Docker。它还会创建一个 docker组，但是默认情况下不会向该组添加任何用户。

2、使用 Docker 部署 OceanBase 数据库
2.1、前提条件
在部署 oceanbase-ce 镜像之前，您需要确认以下信息：
确保您机器的资源至少可以运行 2 核 8GB 以上的Docker。
您的机器已安装最新版的 Docker
您的机器已经启动 Docker 服务。
2.2、启动 OceanBase 数据库
根据当前容器部署最大规格的实例
docker run -p 2881:2881 --name oceanbase-ce -d oceanbase/oceanbase-ce
[root@localhost /]# docker run -p 2881:2881 --name oceanbase-ce -d oceanbase/oceanbase-ce
Unable to find image 'oceanbase/oceanbase-ce:latest' locally
latest: Pulling from oceanbase/oceanbase-ce
2d473b07cdd5: Pull complete
c21cdfe7a94b: Pull complete
7433dd4c409c: Pull complete
00a0e26f2005: Pull complete
Digest: sha256:18c4055f80ec312fc618ef6356ba0da6379c93c45a01b1b5af46e4667c327135
Status: Downloaded newer image for oceanbase/oceanbase-ce:latest
f537c632cd17d3d5eb7f417298b47dfd8ca271f8620eb553428414967e3f80d6
上述命令默认拉取最新版本，可根据实际需求在 Docker 镜像 中选择版本。
启动预计需要 2-5 分钟。执行以下命令，如果返回 boot success!，则启动成功。
$ docker logs oceanbase-ce | tail -1
boot success!
[root@localhost /]# docker logs oceanbase-ce |tail -1
boot success!
2.3、连接 OceanBase 数据库
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。
docker exec -it oceanbase-ce ob-mysql sys # 连接 sys 租户的 root 用户（root@sys）
docker exec -it oceanbase-ce ob-mysql root # 连接 test 租户的 root 用户（root@test）
docker exec -it oceanbase-ce ob-mysql test # 连接 test 租户的 test 用户 （test@test）
也可以运行以下命令，使用您本机的 OBClient 或者 MySQL 客户端连接实例。
$ mysql -uroot -h127.1 -P2881
连接成功后，终端将显示如下内容：
[root@localhost /]# docker exec -it oceanbase-ce ob-mysql sys
login as root@sys
Command is: obclient -h127.1 -uroot@sys -A -Doceanbase -P2881
Welcome to the OceanBase. Commands end with ; or \g.
