Ceph安装问题出现问题

Question

@coding_java 你好，想跟你请教个问题：

（1）安装ceph，命令 ceph-deploy install node0 node1 node2报如下的错

[node0][WARNIN] ensuring that /etc/yum.repos.d/ceph.repo contains a high priority
[ceph_deploy][ERROR ] RuntimeError: NoSectionError: No section: 'ceph'

（2）按照你的说法，yum remove ceph-release  先执行这个，把这个东西卸了

（3）接着安装又报如下的错，

[node0][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy][ERROR ] RuntimeError: Failed to execute command: yum -y install epel-release

能不给我看下是什么问题

Answer 1

经过调查是源文件的问题，我现在将源文件修改如下：

[Ceph]
name=Ceph packages for $basearch
baseurl=http://mirrors.aliyun.com/ceph/rpm-infernalis/el7/$basearch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=http://mirrors.aliyun.com/ceph/keys/release.asc
priority=1

[Ceph-noarch]
name=Ceph noarch packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-infernalis/el7/noarch
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=http://mirrors.aliyun.com/ceph/keys/release.asc
priority=1

[ceph-source]
name=Ceph source packages
baseurl=http://mirrors.aliyun.com/ceph/rpm-infernalis/el7/SRPMS
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=http://mirrors.aliyun.com/ceph/keys/release.asc
priority=1

根据这些LOG ，看不出来什么原因，建议安装之前清理之前安装残留的文件配置。

ceph-deploy purgedata {ceph-node} [{ceph-node}]
ceph-deploy forgetkeys
