yum remove docker docker-common docker-selinux docker-engine
4.安装依赖包
yum install -y yum-utils device-mapper-persistent-data lvm2
5.设置yum源
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
6.运行yum makecache生成缓存
yum clean all
yum makecache
7.安装docker
yum install docker-ce
8.启动docker并加入开机自启
systemctl start docker
systemctl enable docker
