2. CentOS 安装步骤

官网

https://docs.docker.com/engine/install/centos/#prerequisites 先卸载旧版本

sudo yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine

安装yum-utils软件包（提供yum-config-manager 实用程序）并设置稳定的存储库。

sudo yum install -y yum-utils

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

开始安装引擎

sudo yum install docker-ce docker-ce-cli containerd.io

启动

sudo systemctl start docker
