在安装的过程中，遇到了源的问题，找不到包的网页：
重新打开 预装源地址，打开epel-openstack-havana.repo 文件，显示如下：
# Place this file in your /etc/yum.repos.d/ directory [openstack-havana] name=OpenStack Havana Repository for EPEL 6 baseurl=http://repos.fedorapeople.org/repos/openstack/openstack-havana/epel-6 enabled=1 skip_if_unavailable=0 gpgcheck=0 priority=98
于是在/etc/yum.repos.d/ 新创建了一个repo文件 openstack-havana.repo
并yum list 和yum -y update
删除/etc/yum.repos.d/ 中无法找到的源地址文件repo
再进行安装 yum install -y http://rdo.fedorapeople.org/openstack/openstack-havana/rdo-release-havana.rpm 成功
