openstack K版本和ceph对接
本次环境：openstack（K版本）：控制和计算各一台，并且安装到dashboard，可以正常创建虚拟机（搭建过程建官方http://docs.openstack.org/kilo/install-guide/install/yum/content/）
ceph： 共3台，两台节点一台desploy部署机（搭建过程建官方http://ceph.com/）
下面在控制节点安装cinder,在控制节点上操作：
##创建数据库并且授权
# mysql

#yum install python-rbd ceph-common -y
# yum install python-rbd ceph-common -y 把验证文件和ceph的配置文件拷贝到控制节点
# scp ceph.client.admin.keyring ceph.conf 192.168.8.199:/etc/ceph/ 此时在controller节点执行ceph命令是否成功
