1.准备好所有的ceph安装的rpm包。
2.先yum install epel-release -y && yum update -y 。确保可以使用
3.通过yum安装ceph：yum install ceph.x86_64。
主要把一些依赖通过yum安装好。
ceph -v发现当前版本是0.80.7并不是我们需要的包
卸载ceph
yum remove ceph.x86_64
rpm -qa | grep ceph
rpm -qa | grep rbd
rpm -qa | grep rados
删除所有和ceph相关的rpm包，主要是删除低版本的ceph包

4.安装ceph的rpm包并解决依赖包
