##### 一、在线安装 #####

sudo yum install -y yum-utils device-mapper-persistent-data lvm2
    curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
    
    systemctl enable docker
    systemctl start docker
    
    # 下载docker-compose(win下载更快)
    https://github.com/docker/compose/releases/download/1.29.2/docker-compose-Linux-x86_64
    
    # 国内下载
    curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > /usr/bin/docker-compose
    chmod a+x /usr/bin/docker-compose

##### 二、联网下载软件 #####

找一台可以上网的虚拟机把需要的软件提前下载下来

###### 2.1. 下载rpm ######

sudo yum install -y --downloadonly --downloaddir=$PWD/devel yum-utils device-mapper-persistent-data lvm2
    sudo yum install -y devel/*.rpm
    yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
    yum install -y --downloadonly --downloaddir=$PWD/docker docker-ce
    curl -L https://get.daocloud.io/docker/compose/releases/download/1.29.2/docker-compose-`uname -s`-`uname -m` > ./docker-compose

###### 2.2. 安装 docker ######

把刚才下载好的devel文件夹、docker文件夹、docker-compose文件复制到这台无望连接外网的虚拟机上

sudo yum install -y devel/*.rpm
    sudo yum install -y docker/*.rpm
    systemctl enable docker
    systemctl start docker
    chmod a+x ./docker-compose
    cp ./docker-compose /usr/bin/

###### 2.3.测试验证 ######

docker info
    docker-compose -version
