安装包下载地址：https://download.docker.com/linux/static/stable/x86_64/docker-20.10.9.tgz

1、创建文件夹

mkdir -p /data/docker/data

2、上传安装文件到/data/docker下

3、编辑安装脚本

vi /data/docker/install_docker-service.sh

【

#!/bin/bash
#上传安装包到/data/docker目录下
cd /data/docker
#解压安装包到/usr/local目录下
tar -zxvf docker-20.10.9.tgz -C /usr/local

#先删除再插入新的配置文件

rm -rf /etc/systemd/system/docker.service

#编辑配置文件
#/etc/systemd/system/docker.service

#重新加载配置文件
systemctl daemon-reload

#休眠3秒，否者启动失败，因为systemctl daemon-reload命令没有执行完成，马上执行启动服务会报错
sleep 3
#启动服务
systemctl start docker

#先删除再插入新的配置文件

rm -rf /etc/docker/daemon.json

#修改docker文件存放路径
touch /etc/docker/daemon.json
echo '{"data-root": "/data/docker/data"}' >> /etc/docker/daemon.json
#重新加载配置文件
systemctl daemon-reload

#休眠3秒，否者启动失败，因为systemctl daemon-reload命令没有执行完成，马上执行启动服务会报错
sleep 3
#重新启动服务
systemctl restart docker

4、修改 /data/docker/install_docker-service.sh的执行权限

chmod +x  /data/docker/install_docker-service.sh

5、验证

source  /data/docker/install_docker-service.sh

安装成功！！！
