yum clean all

yum makecache

yum install wget

yum update -y

yum install -y yum-utils device-mapper-persistent-data lvm2

yum-config-manager \--add-repo \https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

sed -i 's/download.docker.com/mirrors.aliyun.com\/docker-ce/g' /etc/yum.repos.d/docker-ce.repo
