# 1、安装docker的依赖包：
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 2、使用以下命令设置稳定存储库。（yum源）
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# or  使用阿里镜像
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
# 3、安装docker-ce 
sudo yum install docker-ce docker-ce-cli containerd.io -y

# 4、启动并加入开机启动（或sudo chkconfig docker on） 
sudo systemctl start docker
sudo systemctl enable docker

# 6、查看版本
docker  -v
