大神们说说ceph安装报错这是怎么回事

1、Centos7中：

yum install -y yum-utils

yum-config-manager --add-repo https://dl.fedoraproject.org/pub/epel/7/x86_64/ 不执行yum install --nogpgcheck -y epel-release

rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7

rm -f /etc/yum.repos.d/dl.fedoraproject.org*

配置yum仓库：
vim /etc/yum.repos.d/ceph.repo
[ceph-noarch]
name=Ceph noarch packages
baseurl=http://download.ceph.com/rpm-{ceph-release}/{distro}/noarch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://download.ceph.com/keys/release.asc
更新仓库及安装ceph-deploy
yum -y update 会报错执行：
      yum-config-manager --disable ceph-noarch
      yum-config-manager --save --setopt=ceph-noarch.skip_if_unavailable=true
yum install ceph-deploy -y
ceph-deploy new node1 这里也不报错，会产生三个文件，修改 ceph.conf 添加 osd pool default size = 2
ceph-deploy install admin-node node1 node2 node3就报错
Running command: yum -y install epel-release
[admin-node][DEBUG ] 已加载插件：fastestmirror, priorities
[admin-node][WARNIN] http://ceph.com/rpm-hammer/rhel7/noarch/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found

[admin-node][WARNIN] To address this issue please refer to the below knowledge base article
[admin-node][WARNIN]
[admin-node][WARNIN] https://access.redhat.com/articles/1320623

[admin-node][WARNIN] If above article doesn't help to resolve this issue please create a bug on https://bugs.centos.org/
[admin-node][WARNIN]
[admin-node][WARNIN]
[admin-node][WARNIN]
[admin-node][WARNIN]  One of the configured repositories failed (Ceph noarch packages),
[admin-node][WARNIN]  and yum doesn't have enough cached data to continue. At this point the only
[admin-node][WARNIN]  safe thing yum can do is fail. There are a few ways to work "fix" this:
[admin-node][WARNIN]
[admin-node][WARNIN]    1. Contact the upstream for the repository and get them to fix the problem.
[admin-node][WARNIN]
[admin-node][WARNIN]    2. Reconfigure the baseurl/etc. for the repository, to point to a working
[admin-node][WARNIN]       upstream. This is most often useful if you are using a newer
[admin-node][WARNIN]       distribution release than is supported by the repository (and the
[admin-node][WARNIN]       packages for the previous distribution release still work).
[admin-node][WARNIN]
[admin-node][WARNIN]    3. Disable the repository, so yum won't use it by default. Yum will then
[admin-node][WARNIN]       just ignore the repository until you permanently enable it again or use
[admin-node][WARNIN]       --enablerepo for temporary usage:
[admin-node][WARNIN]
[admin-node][WARNIN]          yum-config-manager --disable Ceph-noarch
[admin-node][WARNIN]
[admin-node][WARNIN]    4. Configure the failing repository to be skipped, if it is unavailable.
[admin-node][WARNIN]       Note that yum will try to contact the repo. when it runs most commands,
[admin-node][WARNIN]       so will have to try and fail each time (and thus. yum will be be much
[admin-node][WARNIN]       slower). If it is a very temporary problem though, this is often a nice
[admin-node][WARNIN]       compromise:
[admin-node][WARNIN]
[admin-node][WARNIN]          yum-config-manager --save --setopt=Ceph-noarch.skip_if_unavailable=true
[admin-node][WARNIN]
[admin-node][WARNIN] failure: repodata/repomd.xml from Ceph-noarch: [Errno 256] No more mirrors to try.
[admin-node][WARNIN] http://ceph.com/rpm-hammer/rhel7/noarch/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
[admin-node][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: yum -y install epel-release
执行者两条命令

yum-config-manager --disable Ceph-noarch
yum-config-manager --save --setopt=Ceph-noarch.skip_if_unavailable=true

还是一样

只好在各个节点手动安装 epel-release 和ceph 但收集密钥的时候会少一个

ceph.bootstrap-rgw.keyring这样的文件

ceph-deploy install admin-node node1 node2 node3就报错
第一个节点已经安装，是否重复了，还要注意权限，路径，环境等因素

Running command: yum -y install epel-release
这个命令我尝试了，是可以执行的。所以楼主检测下自己的环境
