You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest



这是错误信息   求大神指导下，我是不是少添加什么 源了 ？？？

先安装上openstack包

感谢你的热心帮助……我已经启用epel库，并开启了 openstack 的RDO仓库

就在刚才，我 尝试 加入阿里云的镜像源 ，解决了这个 错误。。
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
