新装的centos6.5，安装openstack yum源时报如下错误：

[root@localhost ~]# yum install -y http://repos.fedorapeople.org/repos/openstack/openstack-icehouse/rdo-release-icehouse-4.noarch.rpm

 * base: centos.ustc.edu.cn

 * extras: centos.ustc.edu.cn

 * updates: centos.ustc.edu.cn

解决方式：

[root@localhost ~]# yum clean all

然后重新执行yum安装命令，正常执行。
