3.使用docker提供的脚本安装最新版本

[root@docker ~]# curl -fsSL https://get.docker.com/ | sh

If you would like to use Docker as a non-root user, you should now consider
adding your user to the "docker" group with something like:

 sudo usermod -aG docker your-user

Remember that you will have to log out and back in for this to take effect!

WARNING: Adding a user to the "docker" group will grant the ability to run
 containers which can be used to obtain root privileges on the
 docker host.
 Refer to https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
 for more information.

4.启动docker及设置开机自启

[root@docker ~]# systemctl start docker
[root@docker ~]# systemctl enable docker

5.查看docker及包信息

[root@docker ~]# rpm -qa | grep docker
