Linux 离线安装docker(一键式安装)

    前言

    有时候会遇到服务器不能联网的情况,这样就没法用yum安装软件,docker也是如此,针对这种情况,总结了一下离线安装docker的步骤,分享给大家
    1. 准备docker离线包

    docker官方离线包下载地址
    下载需要安装的docker版本,我此次下载的是
    docker-17.03.2-ce.tgz版本

    2. 准备docker.service 系统配置文件

    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
    # the default is not to use systemd for cgroups because the delegate issues still
    # exists and systemd currently does not support the cgroup feature set required
    # for containers run by docker
    ExecStart=/usr/bin/dockerd
    ExecReload=/bin/kill -s HUP $MAINPID
    # Having non-zero Limit*s causes performance problems due to accounting overhead
    # in the kernel. We recommend using cgroups to do container-local accounting.
    LimitNOFILE=infinity
    LimitNPROC=infinity
    LimitCORE=infinity
    # Uncomment TasksMax if your systemd version supports it.
    # Only systemd 226 and above support this version.
    #TasksMax=infinity
    TimeoutStartSec=0
    # set delegate yes so that systemd does not reset the cgroups of docker containers
    Delegate=yes
    # kill only the docker process, not all processes in the cgroup
    KillMode=process
    # restart the docker process if it exits prematurely
    Restart=on-failure
    StartLimitBurst=3
    StartLimitInterval=60s
    
    [Install]
    WantedBy=multi-user.target
    
    3. 准备安装脚本和卸载脚本

    安装脚本 install.sh

    #!/bin/sh
    echo '解压tar包...'
    tar -xvf $1
    
    echo '将docker目录移到/usr/bin目录下...'
    cp docker/* /usr/bin/
    
    echo '将docker.service 移到/etc/systemd/system/ 目录...'
    cp docker.service /etc/systemd/system/
    
    echo '添加文件权限...'
    chmod +x /etc/systemd/system/docker.service
    
    echo '重新加载配置文件...'
    systemctl daemon-reload
    
    echo '启动docker...'
    systemctl start docker
    
    echo '设置开机自启...'
    systemctl enable docker.service
    
    echo 'docker安装成功...'
    docker -v
    

    卸载脚本 uninstall.sh

    #!/bin/sh
    
    echo '删除docker.service...'
    rm -f /etc/systemd/system/docker.service
    
    echo '删除docker文件...'
    rm -rf /usr/bin/docker*
    
    echo '重新加载配置文件'
    systemctl daemon-reload
    
    echo '卸载成功...'
    
    4. 安装
    • 4.1 此时目录为:(只需要关注docker-17.03.2-ce.tgz、docker.service、install.sh、uninstall.sh即可)

    • 4.2 执行脚本 sh install.sh docker-17.03.2-ce.tgz
      执行过程如下:
      2.PNG

    待脚本执行完毕后,执行docker -v
    发现此时docker已安装成功,可以用docker --help 查看docker命令,从现在开始你就可以自己安装image和container了

    • 4.3 如果你想卸载docker,此时执行脚本 sh uninstall.sh即可,执行过程如下:
      3.PNG
      此时输入docker -v,发现docker已经卸载
    多次动手操作以后,发现docker离线安装如此方便,希望对你有所帮助
