一、前期准备安装ceph-deploy工具
所有的服务器都是用root用户登录的
1、安装环境
系统centos-6.5
设备：1台admin-node (ceph-ploy) 1台 monistor 2台 osd
2、关闭所有节点的防火墙及关闭selinux，重启机器。
service iptables stop
sed -i '/SELINUX/s/enforcing/disabled/' /etc/selinux/config
chkconfig iptables off
3、编辑admin-node节点的ceph yum仓库
vi /etc/yum.repos.d/ceph.repo
[ceph-noarch]
name=Ceph noarch packages
baseurl=http://ceph.com/rpm/el6/noarch/
enabled=1
gpgcheck=1
type=rpm-md
gpgkey=https://ceph.com/git/?p=ceph.git;a=blob_plain;f=keys/release.asc
4、安装搜狐的epel仓库
rpm -ivh http://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
5、更新admin-node节点的yum源
yum clean all
yum update -y
6、在admin-node节点上建立一个ceph集群目录
mkdir /ceph
cd /ceph
7、在admin-node节点上安装ceph部署工具
yum install ceph-deploy -y
8、配置admin-node节点的hosts文件
vi /etc/hosts
10.240.240.210 admin-node
10.240.240.211 node1
10.240.240.212 node2
10.240.240.213 node3
二、配置ceph-deploy部署的无密码登录每个ceph节点
1、在每个Ceph节点上安装一个SSH服务器
[ceph@node3 ~]$ yum install openssh-server -y
2、配置您的admin-node管理节点与每个Ceph节点无密码的SSH访问。
[root@ceph-deploy ceph]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
3、复制admin-node节点的秘钥到每个ceph节点
ssh-copy-id root@admin-node
ssh-copy-id root@node1
ssh-copy-id root@node2
ssh-copy-id root@node3
4、测试每台ceph节点不用密码是否可以登录
ssh root@node1
ssh root@node2
ssh root@node3
5、修改admin-node管理节点的~/.ssh / config文件，这样它登录到Ceph节点创建的用户
Host admin-node
Hostname admin-node
User root
Host node1
Hostname node1
User root
Host node2
Hostname node2
User root
Host node3
Hostname node3
User root
三、用ceph-deploy工具部署ceph集群
1、在admin-node节点上新建一个ceph集群
[root@admin-node ceph]# ceph-deploy new node1
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (1.5.3): /usr/bin/ceph-deploy new node1
[ceph_deploy.new][DEBUG ] Creating new cluster named ceph
[ceph_deploy.new][DEBUG ] Resolving host node1
[ceph_deploy.new][DEBUG ] Monitor node1 at 10.240.240.211
[ceph_deploy.new][INFO ] making sure passwordless SSH succeeds
[node1][DEBUG ] connected to host: admin-node
[node1][INFO ] Running command: ssh -CT -o BatchMode=yes node1
[ceph_deploy.new][DEBUG ] Monitor initial members are ['node1']
[ceph_deploy.new][DEBUG ] Monitor addrs are ['10.240.240.211']
[ceph_deploy.new][DEBUG ] Creating a random mon key...
[ceph_deploy.new][DEBUG ] Writing initial config to ceph.conf...
[ceph_deploy.new][DEBUG ] Writing monitor keyring to ceph.mon.keyring...
查看生成的文件
[root@admin-node ceph]# ls
ceph.conf ceph.log ceph.mon.keyring
2、部署之前确保ceph每个节点没有ceph数据包（先清空之前所有的ceph数据，如果是新装不用执行此步骤，如果是重新部署的话也执行下面的命令）
[root@ceph-deploy ceph]# ceph-deploy purgedata admin-node node1 node2 node3
[root@ceph-deploy ceph]# ceph-deploy forgetkeys
[root@ceph-deploy ceph]# ceph-deploy purge admin-node node1 node2 node3
如果是新装的话是没有任何数据的
3、编辑admin-node节点的ceph配置文件，把下面的配置放入ceph.conf中
osd pool default size = 2
4、在admin-node节点用ceph-deploy工具向各个节点安装ceph
[root@admin-node ceph]# ceph-deploy install admin-node node1 node2 node3
若果装到某个节点时提示 ImportError: No module named argparse这个报错，手动在报错的节点上执行下面的命令后再重新安装报错节点。
[root@node2 ~]# yum install *argparse* -y
5、添加初始监控节点并收集密钥(新的ceph-deploy v1.1.3以后的版本)。
[root@admin-node ceph]# ceph-deploy mon create-initial
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (1.5.3): /usr/bin/ceph-deploy mon create-initial
[ceph_deploy.mon][DEBUG ] Deploying mon, cluster ceph hosts node1

[node1][DEBUG ] ceph-mon: created monfs at /var/lib/ceph/mon/ceph-node1 for mon.node1
[node1][INFO ] unlinking keyring file /var/lib/ceph/tmp/ceph-node1.mon.keyring

[node1][INFO ] Running command: /sbin/service ceph -c /etc/ceph/ceph.conf start mon.node1

[node1][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy.mon][ERROR ] Failed to execute command: /sbin/service ceph -c /etc/ceph/ceph.conf start mon.node1
[ceph_deploy][ERROR ] GenericError: Failed to create 1 monitors
解决上面报错信息的方法：
手动在mon(node1)节点上执行下面的命令
[root@node1 ~]# yum install redhat-lsb -y
查看ceph集群目录多了下面几个文件
ceph.bootstrap-mds.keyring
ceph.bootstrap-osd.keyring
ceph.client.admin.keyring
6、添加osd节点
先添加node2节点，进入node2节点查看未分配的分区
[root@admin-node ceph]# ssh node2
[root@node2 ~]# fdisk -l
Disk /dev/sda: 53.7 GB, 53687091200 bytes
255 heads, 63 sectors/track, 6527 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000d6653
Device Boot Start End Blocks Id System
/dev/sda1 * 1 39 307200 83 Linux
Partition 1 does not end on cylinder boundary.

/dev/sda3 6401 6528 1015808 82 Linux swap / Solaris
Disk /dev/sdb: 21.5 GB, 21474836480 bytes
255 heads, 63 sectors/track, 2610 cylinders

/dev/sdb1 1 2610 20964793+ 5 Extended

[root@node2 ~]# df -h

/dev/sda1 291M 33M 243M 12% /boot
查看可以看出第二块硬盘为使用，使用第二块硬盘的sdb5分区作为osd硬盘
在admin-node节点上添加osd设备
[root@admin-node ceph]#ceph-deploy osd prepare node2:/dev/sdb5
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (1.5.3): /usr/bin/ceph-deploy osd prepare node2:/var/local/osd0 node3:/var/local/osd1

[node3][WARNIN] osd keyring does not exist yet, creating one
[node3][DEBUG ] create a keyring file
[ceph_deploy.osd][ERROR ] IOError: [Errno 2] No such file or directory: '/var/lib/ceph/bootstrap-osd/ceph.keyring'
[ceph_deploy][ERROR ] GenericError: Failed to create 2 OSDs
解决上面报错信息的方法如下：
上面错误信息的意思是：在创建osd节点的时候在osd节点上缺少/var/lib/ceph/bootstrap-osd/ceph.keyring文件，查看Node1的监控节点发现有这个文件，把Node1节点上的文件拷贝到node2节点上去即可。
在node2节点上建立一个目录：mkdir /var/lib/ceph/bootstrap-osd/。
登录node1：
[root@admin-node ceph]# ssh node1
[root@admin-node ceph]#scp /var/lib/ceph/bootstrap-osd/ceph.keyring root@node2:/var/lib/ceph/bootstrap-osd/
再次执行osd初始化命令
[root@admin-node ceph]# ceph-deploy osd prepare node2:/dev/sdb5
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (1.5.3): /usr/bin/ceph-deploy osd prepare node2:/dev/sdb5
[ceph_deploy.osd][DEBUG ] Preparing cluster ceph disks node2:/dev/sdb5:

[node2][ERROR ] RuntimeError: command returned non-zero exit status: 1
[ceph_deploy.osd][ERROR ] Failed to execute command: ceph-disk-prepare --fs-type xfs --cluster ceph -- /dev/sdb5
[ceph_deploy][ERROR ] GenericError: Failed to create 1 OSDs
上面的报错信息说明在node2上没有mkfs.xfs文件，需要在node2上安装mkfs.xfs文件。
[root@admin-node ceph]# ssh node2
[root@node2 ~]# yum install xfs* -y
再次执行osd初始化命令可以成功初始化新加入的osd节点
在admin节点上激活osd设备
[root@admin-node ceph]# ceph-deploy osd activate node2:/dev/sdb5
[ceph_deploy.conf][DEBUG ] found configuration file at: /root/.cephdeploy.conf
[ceph_deploy.cli][INFO ] Invoked (1.5.3): /usr/bin/ceph-deploy osd activate node2:/dev/sdb5

上面报错信息的意思是：在node2节点上没有/var/lib/ceph/osd/ceph-0这个目录，需要在node2节点上创建这个目录。
[root@admin-node ceph]# ssh node2
[root@node2 ~]# mkdir /var/lib/ceph/osd/
