linux 离线安装docker

测试服务器：银河麒麟V10 x86_64

注意：推荐使用国内的镜像站下载，因为官网不挂梯子无法访问，我用的是清华大学开源软件镜像站

一、下载离线包：

官网下载docker离线包

下载地址：https://download.docker.com/linux/static/stable/

清华大学docker安装包

下载地址：https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/static/stable

根据自己的操作系统选择合适的镜像，如下图所示：

我本地的虚拟机是x86_64位的，所以选择x86_64目录找到对应的版本下载

下载完成后，可以放到服务器上，进行安装操作。

二、执行安装操作

使用 tar -zxvf docker-20.10.10.tgz 命令进行解压操作，解压后会在当前目录下生成docker文件

执行如下命令把docker相关文件拷贝到/usr/bin目录

sudo cp -p docker/* /usr/bin

创建docker.service文件，实现开机自启动

touch docker.service

然后把如下内容，贴到docker.service文件中
