离线安装docker

 

1、docker下载

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

所有版本都有，根据你的需求去选择。我这里下载的docker版本号是20.10.23

# wget  https://download.docker.com/linux/static/stable/x86_64/docker-20.10.23.tgz

2、解压

# tar zxvf docker-20.10.23.tgz # cp docker/* /usr/bin/

3、创建服务文件

# vim /etc/systemd/system/docker.service  (创建配置文件)

4、启动​​​​​​​

chmod +x /etc/systemd/system/docker.servicesystemctl daemon-reloadsystemctl start dockersystemctl enable dockerdocker --version# Docker version 20.10.23, build 7155243

5、配置加速器加速下载docker镜像​​​​​​​

vim /etc/docker/daemon.json{"registry-mirrors": ["https://gg3gwnry.mirror.aliyuncs.com"]}重启服务：systemctl daemon-reloadsystemctl restart docker
