我一直按照以下教程在 CentOS 上设置 ceph
https://wiki.centos.org/SpecialInterestGroup/Storage/ceph-Quickstart
当我尝试运行ceph-deploy安装到我的其他节点时，出现以下错误：

答案1
由于 URL 不存在，以下命令失败：
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: rpm -Uvh --replacepkgs http://ceph.com/rpm-hammer/el7/noarch/ceph-release-1-0.el7.noarch.rpm
一个迹象是 HTML 代码溢出到了脚本中：
[ceph-osd0][DEBUG ] Retrieving http://ceph.com/rpm-hammer/el7/noarch/ceph-release-1-0.el7.noarch.rpm
[ceph-osd0][WARNIN] error: open of <html> failed: No such file or directory

[ceph-osd0][WARNIN] error: open of of failed: No such file or directory
[ceph-osd0][WARNIN] error: open of /rpm-hammer/</title></head> failed: No such file or directory
URL 应为（原始 URL 中缺少http://download.ceph.com/rpm-hammer/el7/noarch/ceph-release-1-0.el7.noarch.rpm子域名）download
要解决此问题，请更改管理节点上的文件中的 URL lib/python2.7/site-packages/ceph_deploy/hosts/centos/install.py，然后重新运行该命令。
