在我的 Cent OS6.5 中，我想安装以下内容：
[root@localhost /]# yum install -y http://rdo.Fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly-1.noarch.rpm
但我得到以下信息：
[root@localhost /]# yum install -y http://rdo.Fedorapeople.org/openstack/openstack-grizzly/rdo-release-grizzly-1.noarch.rpm
Loaded plugins: fastestmirror

Setting up Install Process

如何修复它？
