CentOS 7.2 x86_64安装Openstack报错，小白，求帮助！！！

小弟最近尝试搭Openstack测试环境遇到问题，openstack版本尝试过k到o,都会遇到同样的问题，貌似是缺少ruby(selinux)，百度找了很久，没见人有遇到同样的问题

系统版本：CentOS Linux release 7.2.1511 (Core)
内核版本：3.10.0-327.el7.x86_64
uname -a输出：Linux localhost.localdomain 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Yum源：http://mirror.centos.org/centos/7/cloud/x86_64/openstack-mitaka/

下面是命令以及报错：

[root@localhost ~]# packstack --allinone

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