2. Configure Alibaba Cloud yum source warehouse

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo 
# 如果找不到yum-config-manager就通过命令yum -y install yum-utils 安装就可以使用yum-config-manager命令

3. View the docker version that can be installed

yum list docker-ce --showduplicates | sort -r #查看可以安装的版本并倒序排序

4. Install the latest version of Docker

sudo yum install -y docker-ce #注意：安装Docker最新版本，无需加版本号；或者选择你需要的版本安装

5. Set up Docker Aliyun Accelerator

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://lkq3q0he.mirror.aliyuncs.com"]
}
EOF

6. Start Docker

sudo systemctl daemon-reload #重新加载服务配置文件

sudo systemctl enable docker.service && systemctl restart docker.service   #设置开机启动与重启docker服务
