错误整理
1. 如若在配置过程中出现问题，重新创建集群或重新安装ceph，那么需要将ceph集群中的数据都清除掉，命令如下；
[dhhy@dlp ceph-cluster]$ ceph-deploy purge node1 node2
[dhhy@dlp ceph-cluster]$ ceph-deploy purgedata node1 node2
[dhhy@dlp ceph-cluster]$ ceph-deploy forgetkeys && rm ceph.*
2.dlp节点为node节点和客户端安装ceph时，会出现yum安装超时，大多由于网络问题导致，可以多执行几次安装命令；
3.dlp节点指定ceph-deploy命令管理node节点配置时，当前所在目录一定是/home/dhhy/ceph-cluster/，不然会提示找不到ceph.conf的配置文件；
4.osd节点的/var/local/osd*/存储数据实体的目录权限必须为777，并且属主和属组必须为ceph；
5. 在dlp管理节点安装ceph时出现以下问题
解决方法：
1.重新yum安装node1或者node2的epel-release软件包；
2.如若还无法解决，将软件包下载，使用以下命令进行本地安装；
6.如若在dlp管理节点中对/home/yzyu/ceph-cluster/ceph.conf主配置文件发生变化，那么需要将其主配置文件同步给node节点，命令如下：
node节点收到配置文件后，需要重新启动进程：
7.在dlp管理节点查看ceph集群状态时，出现如下，原因是因为时间不一致所导致；
将dlp节点的ntpd时间服务重新启动，node节点再次同步时间即可，如下所示：
8.在dlp管理节点进行管理node节点时，所处的位置一定是/home/yzyu/ceph-cluster/，不然会提示找不到ceph.conf主配置文件；
