tar -zxvf docker-20.10.9.tgz
解压后的文件如下所示

4、复制文件
cd docker
cp ./* /usr/bin
5、创建docker.service文件
cd /etc/systemd/system/
touch docker.service
6、编辑docker.service 文件
vim docker.service
注意：将其中的ip地址，改成您的服务器地址，其它参数不用改。

修改完成后的docker.service

7、 添加可执行权限
chmod +x docker.service
8、加载docker.service
systemctl daemon-reload
注意，若修改了docker.service文件，则要重新加载该文件。
9、启动docker
systemctl start docker
10、查看docker
systemctl status docker

11、查看docker版本
docker -v
[root@0001 system]# docker -v
Docker version 20.10.9, build c2ea9bc
