看了一下网上，大部分都是指在CENTOS 上安装DOCKER，但CENTOS上没有9以上的版本，怎么办？
我们知道 Oracle linux ,在 https://download.docker.com/linux/ 下面，没有专门的oracle linux 目录，要找ORacle linux 下的docker，直接使用 centos 即可。
1.先安装oracle linux 9.6
最小安装即可，保证能上网即可。
2.安装docker yum 源
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
如果觉得比较慢，可以使用国内的替换
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3.安装依赖包 yum install yum-utils device-mapper-persistent-data lvm2 -y
4.安装docker
yum install docker-ce docker-ce-cli containerd.io -y
5.设置并启动docker
systemctl start --now docker
systemctl status docker
6.查看docker版本

This message shows that your installation appears to be working correctly. To generate this message, Docker took the following steps: 1. The Docker client contacted the Docker daemon. 2. The Docker daemon pulled the "hello-world" image from the Docker Hub. (amd64) 3. The Docker daemon created a new container from that image which runs the executable that produces the output you are currently reading. 4. The Docker daemon streamed that output to the Docker client, which sent it to your terminal. To try something more ambitious, you can run an Ubuntu container with: $ docker run -it ubuntu bash Share images, automate workflows, and more with a free Docker ID: [https://hub.docker.com/](https://hub.docker.com/ "https://hub.docker.com/") For more examples and ideas, visit: [https://docs.docker.com/get-started/](https://docs.docker.com/get-started/ "https://docs.docker.com/get-started/")
