解决办法：
先删除docker
yum remove -y docker \
    docker-ce \
    docker-client \
    docker-client-latest \
    docker-common \
    docker-latest \
    docker-latest-logrotate \
    docker-logrotate \
    docker-selinux \
    docker-engine-selinux \
    docker-engine
    rm -rf /var/lib/docker
    rm -rf /run/docker
    rm -rf /var/run/docker
    rm -rf /etc/docker


再重新安装docker
yum install -y yum-utils
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum install docker-ce docker-ce-cli containerd.io docker-compose-plugin

systemctl start docker
