Centos7离线安装Docker脚本

1、文件结构

docker_install/
├── docker-27.4.1.tgz
├── docker-compose-linux-x86_64
└── docker_install.sh

2、下载docker安装包

wget https://download.docker.com/linux/static/stable/x86_64/docker-27.4.1.tgz

3、下载docker-compose

wget https://github.com/docker/compose/releases/download/v2.32.1/docker-compose-linux-x86_64

4、编写安装脚本

#!/bin/bash


# docker安装
docker_install() {
    echo -e '\033[31m 解压文件至/usr/bin/目录 \033[0m'
    tar -zxvf docker-27.4.1.tgz
    chmod +x docker/* && cp docker/* /usr/bin/
