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。

3.ceph的安装

  1. 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

10.1.2.232compute1_10_1_2_232OSD/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

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

to make sure we haven't added extra keys that you weren't expecting.
[root@controller_10_1_2_230 ~]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@network_10_1_2_231

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 
[global]
auth_service_required = cephx            
filestore_xattr_use_omap = true

e、校验ceph状态

PS:由于目前还没有OSD,所有集群目前的health健康状态为:HEALTH_ERR,添加之后,就不会报错了@@

7.添加OSD,按照准备条件,先格式化为xfs文件系统并挂载

a、创建目录
[root@controller_10_1_2_230 ceph-deploy]# ssh root@network_10_1_2_231 'mkdir -pv /data1/osd0'
mkdir: created directory `/data1/osd0'
[root@controller_10_1_2_230 ceph-deploy]# ssh compute1_10_1_2_232 'mkdir -pv /data1/osd1'

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!
