1.下载安装

[root@openEuler-node1 ~]# wget -c https://download.docker.com/linux/static/stable/x86_64/docker-25.0.3.tgz
[root@openEuler-node1 ~]# wget -c https://download.docker.com/linux/static/stable/x86_64/docker-rootless-extras-25.0.3.tgz

 2.解压到指定目录

[root@openEuler-node1 ~]# tar xf docker-25.0.3.tgz -C /usr/local/

3.写配置文件 

[root@openEuler-node1 docker]# vi /usr/lib/systemd/system/docker.service
