Docker之离线安装和在线安装

一、离线安装
1、软件包下载
去官网下载docker 安装二进制包，选择适合自己的版本。这里下载的是docker-19.03.9.tgz，在centos7中安装（cento6无法使用，提示linux版本内核版本太低）

https://download.docker.com/linux/static/stable/x86_64/

2、安装docker

tar xvf /opt/docker-24.0.7.tgz -C /usr/local/
cd /usr/local/
cp docker/* /usr/bin/

tee /etc/systemd/system/docker.service <<EOF

二、在线安装
1、安装脚本在线安装
curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun
2、镜像加速配置

sudo mkdir -p /etc/docker 
sudo tee /etc/docker/daemon.json <<-'EOF'

"registry-mirrors": ["https://b49nkdcy.mirror.aliyuncs.com"]
