HOWTO Install Ceph On FC12, FC上安装Ceph分布式文件系统

#下载源代码
$ git clone git://ceph.newdream.net/git/ceph-client-standalone.git
$ git branch master-backport origin/master-backport
$ git checkout master-backport
#编译
$ make or make KERNELDIR=/usr/src/… #前者表示用于当前在用内核,后者其它路径
# 编译成功后会产生ceph.ko
$ make install
$ modprobe ceph or inmod ceph.ko

[root@ceph_mds ceph]# cat ceph.conf
;
; Sample ceph ceph.conf file.
;
; This file defines cluster membership, the various locations
; that Ceph stores data, and any other runtime options.

; If a 'host' is defined for a daemon, the start/stop script will
; verify that it matches the hostname (or else ignore it). If it is
; not defined, it is assumed that the daemon is intended to start on
; the current host (e.g., in a setup with a startup.conf on each
; node).

; global

; enable secure authentication
; auth supported = cephx

; monitors
; You need at least one. You need at least three if you want to
; tolerate any node failures. Always create an odd number.
[mon]
mon data = /data/mon$id

; some minimal logging (just message traffic) to aid debugging
debug ms = 1

[mon0]
host = ceph_mds
mon addr = 192.168.233.182:6789

; mds
; You need at least one. Define two to get a standby.
[mds]
; where the mds keeps it's secret encryption keys
keyring = /data/keyring.$name

[mds.alpha]
host = ceph_mds

; osd
; You need at least one. Two if you want data to be replicated.
; Define as many as you like.
[osd]
sudo = true
; This is where the btrfs volume will be mounted.
osd data = /data/osd$id

; Ideally, make this a separate disk or partition. A few GB
; is usually enough; more if you have fast disks. You can use
; a file under the osd data dir if need be
; (e.g. /data/osd$id/journal), but it will be slower than a
; separate disk or partition.
;osd journal = /data/osd$id/journal

[osd0]
host = ceph_osd
btrfs devs = /dev/sdb1

[osd1]
host = ceph_osd1

; you probably want to limit this to a small or a list of
; hosts. clients are fully trusted.

[root@ceph_mds ceph]# cat fetch_config
#!/bin/sh
conf="$1"

## fetch ceph.conf from some remote location and save it to $conf.
##
## make sure this script is executable (chmod +x fetch_config)

##
## examples:
##

## from a locally accessible file
# cp /path/to/ceph.conf $conf

## from a URL:
# wget -q -O $conf http://somewhere.com/some/ceph.conf

## via scp
# scp -i /path/to/id_dsa user@host:/path/to/ceph.conf $conf
scp root@ceph_mds:/usr/local/etc/ceph/ceph.conf $conf
