1.前言
企业上线openstack，必须要思考和解决三方面的难题:1.控制集群的高可用和负载均衡，保障集群没有单点故障，持续可用，2.网络的规划和neutron L3的高可用和负载均衡，3. 存储的高可用性和性能问题。存储openstack中的痛点与难点之一，在上线和运维中，值得考虑和规划的重要点，openstack支持各种存储，包括分布式的文件系统，常见的有:ceph,glusterfs和sheepdog，同时也支持商业的FC存储，如IBM,EMC,NetApp和huawei的专业存储设备，一方面能够满足企业的利旧和资源的统一管理。
2. ceph概述
ceph作为近年来呼声最高的统一存储，在云环境下适应而生，ceph成就了openstack和cloudstack这类的开源的平台方案，同时openstack的快速发展，也吸引了越来越多的人参与到ceph的研究中来，在过去的2015年中，ceph在整个社区的活跃度越来越高，越来越多的企业，使用ceph做为openstack的glance，nova，cinder的存储。
ceph是一种统一的分布式文件系统，能够支持三种常用的接口:1.对象存储接口，兼容于S3，用于存储结构化的数据，如图片，视频，音频等文件，其他对象存储有:S3,Swift,FastDFS等；2. 文件系统接口，通过cephfs来完成，能够实现类似于nfs的挂载文件系统，需要由MDS来完成，类似的文件系存储有:nfs,samba,glusterfs等；3. 块存储，通过rbd实现，专门用于存储云环境下块设备，如openstack的cinder卷存储，这也是目前ceph应用最广泛的地方。
ceph的体系结构：
3.ceph的安装
环境介绍，通过ceph-depoly的方式部署ceph，三台角色如下,按照需求配置好hostname并格式化磁盘为xfs并挂载
| ip | 主机名 | 角色 | 磁盘 |
| 10.1.2.230 | controller_10_1_2_230 | Monitor/admin-deploy | |
| 10.1.2.231 | network_10_1_2_231 | OSD | /data1/osd0,格式化为xfs |
| 10.1.2.232 | compute1_10_1_2_232 | OSD | /data1/osd1,格式化为xfs |
2.yum源的准备，需要配置好Epel源和ceph源
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
[root@controller_10_1_2_230 ~]# yum repolist Loaded plugins: fastestmirror, priorities Repository epel is listed more than once in the configuration Repository epel-debuginfo is listed more than once in the configuration Repository epel-source is listed more than once in the configuration Determining fastest mirrors base | 3.7 kB 00:00 base/primary_db | 4.4 MB 00:01 ceph | 2.9 kB 00:00 ceph/primary_db | 24 kB 00:00 epel | 4.4 kB 00:00 epel/primary_db | 6.3 MB 00:00 extras | 3.3 kB 00:00 extras/primary_db | 19 kB 00:00 openstack-icehouse | 2.9 kB 00:00 openstack-icehouse/primary_db | 902 kB 00:00 updates | 3.4 kB 00:00 updates/primary_db | 5.3 MB 00:00 211 packages excluded due to repository priority protections repo id repo name status base CentOS-6 - Base 6,311+56 ceph ceph 21+1 epel Extra Packages for Enterprise Linux 6 - x86_64 11,112+36 extras CentOS-6 - Extras 15 openstack-icehouse OpenStack Icehouse Repository 1,353+309 updates CentOS-6 - Updates 1,397+118 repolist: 20,209
3.配置ntp，所有的机器均需要配置ntp服务器，统一同步到内网的ntp服务器，参考:
[root@compute1_10_1_2_232 ~]# vim /etc/ntp.conf server 10.1.2.230 [root@compute1_10_1_2_232 ~]# /etc/init.d/ntpd restart Shutting down ntpd: [ OK ] Starting ntpd: [ OK ] [root@compute1_10_1_2_232 ~]# chkconfig ntpd on [root@compute1_10_1_2_232 ~]# chkconfig --list ntpd ntpd 0:off 1:off 2:on 3:on 4:on 5:on 6:off
4.安装ceph，在所有的节点上都需要安装ceph，在admin节点，需要安装另外一个ceph-deploy，用于软件部署
[root@controller_10_1_2_230 ~]# yum install ceph ceph-deploy #管理节点 [root@network_10_1_2_231 ~]# yum install ceph -y #OSD节点 [root@compute1_10_1_2_232 ~]# yum install ceph -y #OSD节点
5.生成SSH key秘钥，并拷贝至远端
a、生成key [root@controller_10_1_2_230 ~]# 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. The key fingerprint is: 75:b4:24:cd:24:a6:a4:a4:a5:c7:da:6f:e7:29:ce:0f root@controller_10_1_2_230 The key's randomart p_w_picpath is: +--[ RSA 2048]----+ | o . +++ | | * o o =o. | | o + . . o | | + . . | | . . S | | . | | E . | | o.+ . | | .oo+ | +-----------------+ b、将key拷贝至远端 [root@controller_10_1_2_230 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@controller_10_1_2_230 The authenticity of host '[controller_10_1_2_230]:32200 ([10.1.2.230]:32200)' can't be established. RSA key fingerprint is 7c:6b:e6:d5:b9:cc:09:d2:b7:bb:db:a4:41:aa:5e:34. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[controller_10_1_2_230]:32200,[10.1.2.230]:32200' (RSA) to the list of known hosts. root@controller_10_1_2_230's password: Now try logging into the machine, with "ssh 'root@controller_10_1_2_230'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.

RSA key fingerprint is de:27:84:74:d3:9c:cf:d5:d8:3e:c4:65:d5:9d:dc:9a. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[network_10_1_2_231]:32200,[10.1.2.231]:32200' (RSA) to the list of known hosts. root@network_10_1_2_231's password: Now try logging into the machine, with "ssh 'root@network_10_1_2_231'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.

RSA key fingerprint is d7:3a:1a:3d:b5:26:78:6a:39:5e:bd:5d:d4:96:29:0f. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '[compute1_10_1_2_232]:32200,[10.1.2.232]:32200' (RSA) to the list of known hosts. root@compute1_10_1_2_232's password: Now try logging into the machine, with "ssh 'root@compute1_10_1_2_232'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting. c、测试是否能无密码登陆 [root@controller_10_1_2_230 ~]# ssh root@compute1_10_1_2_232 'df -h' Filesystem Size Used Avail Use% Mounted on /dev/sda2 9.9G 3.3G 6.1G 35% / tmpfs 3.9G 8.0K 3.9G 1% /dev/shm /dev/sda1 1008M 82M 876M 9% /boot /dev/sda4 913G 33M 913G 1% /data1
6.创建初始Monitor节点
a、创建配置目录，后续所有的操作都在该目录下执行
[root@controller_10_1_2_230 ~]# mkdir ceph-deploy
[root@controller_10_1_2_230 ~]# cd ceph-deploy/
b、新建一个集群
[root@controller_10_1_2_230 ceph-deploy]# ceph-deploy new --cluster-network 10.1.2.0/24 --public-network 10.1.2.0/24 controller_10_1_2_230

c、修改副本的个数
[root@controller_10_1_2_230 ceph-deploy]# vim ceph.conf

至此，基本的ceph配置完毕！！！
4. 总结
以上配置是ceph的最基本的配置，此处只是作为练习使用，在生产中，实际用ceph，需要考虑的因素非常多，如monitor需要有3个，ceph的集群网络和公共网络的规划，OSD策略的调整等等，请继续关注我的blog，后续将会以ceph系列文章的形式出现，此处只是做简单的演示，接下来的博客，将介绍ceph和glance，nova，以及cinder结合，敬请关注！
