安装Docker 这里使用Docker作为容器引擎，也可以换成别的，例如containerd

下载地址：https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz https://download.docker.com/linux/static/stable/x86_64/docker-24.0.5.tgz 以下在所有节点操作。这里采用二进制安装，用yum安装也一样。 3.1 解压二进制包 tar zxvf docker-19.03.9.tgz mv docker/* /usr/bin 3.2 systemd管理docker
