docker&docker-compose离线安装

1.docker离线安装包下载并安装（本次使用压缩包方式安装）
    压缩包安装地址
        下载地址：https://download.docker.com/linux/static/stable/x86_64/ 
    rpm安装包以及参考安装文档：
        rpm安装包下载地址：https://download.docker.com/linux/centos/7/x86_64/stable/Packages/ 
        rpm安装参考地址：https://www.cnblogs.com/shuhe-nd/p/13031531.html
    1.加压docker-19.03.9.tgz
        tar axvf docker-19.03.9.tgz -C apps/
    2.复制docker目录下内容到/usr/bin/目录
        cp -r docker/* /usr/bin/
    3.添加docker启动service
        vim /etc/systemd/system/docker.service
        [Unit]
    Description=Docker Application Container Engine
    Documentation=https://docs.docker.com
    After=network-online.target firewalld.service
    Wants=network-online.target
    [Service]
    Type=notify
    ExecStart=/usr/bin/dockerd
    ExecReload=/bin/kill -s HUP $MAINPID
    LimitNOFILE=infinity
    LimitNPROC=infinity
    TimeoutStartSec=0
    Delegate=yes
    KillMode=process
    Restart=on-failure
    StartLimitBurst=3
    StartLimitInterval=60s
    [Install]
    WantedBy=multi-user.target
   4.启动服务添加权限&设置docker开机启动以及加速镜像
        chmod +x /etc/systemd/system/docker.service
        systemctl daemon-reload
        systemctl enable docker
        systemctl start docker
        docker --version
        sudo mkdir -p /etc/docker
        sudo vi /etc/docker/daemon.json
        {
                "registry-mirrors": ["http://hub-mirror.c.163.com"]
            }
            
        5.docker-compose离线安装
            docker-compose离线安装包下载：https://github.com/docker/compose/releases
      1. cp docker-compose /usr/local/bin/docker-compose    
      2. chmod  +x /usr/local/bin/docker-compose
      3. docker-compose -v
