前言
1. 文档很初级,只是为了带新手入门,很多参数使用默认值
2. 文档中Ceph不使用ceph-deploy部署
3. 后续会有telemetry,lbaas,sahara,swift,trove部署文档
4. 如果网卡不够,可以将管理,虚机,存储合并为一个网络
5. 文档中ceph只建立一个池子
6. rdo中某些服务的conf文件红帽有一些修改,如果大家享用官方原版可以在launchpad下载源码包自行生成(这是说给强迫症用户的)
7. dvr模式下每个l3节点所绑定网卡都需要有外网ip

架构图

架构部署

7. 建立监视器节点对应关系地图
monmaptool --create --add Kilo-com-1 20.0.0.3 --fsid 第二步生成的值也是 /tmp/monmap

8. 建立监视器服务数据存放目录
mkdir /var/lib/ceph/mon/ceph-Kilo-com-1

ceph mon add Kilo-com-2 20.0.0.4:6789

11. 将/etc/ceph/ceph.conf覆盖到其他节点的ceph目录并重启服务

部署OSD

1. 申请OSD号,计划当前节点有几个OSD就执行几次,输出结果后续使用,我这里每个节点三个OSD,我需要执行三次
ceph osd tree

2. 通过OSD号创建OSD数据目录
mkdir /var/lib/ceph/osd/ceph-0
mkdir /var/lib/ceph/osd/ceph-1
mkdir /var/lib/ceph/osd/ceph-2

3. 格式化OSD使用磁盘为xfs文件系统
mkfs.xfs /dev/sdb
mkfs.xfs /dev/sdc
mkfs.xfs /dev/sdd

4. 编辑/etc/fstab添加如下内容
/dev/sdb /var/lib/ceph/osd/ceph-0 xfs defaults 0 0
/dev/sdb /var/lib/ceph/osd/ceph-0 xfs remount,user_xattr 0 0

/dev/sdc /var/lib/ceph/osd/ceph-1 xfs remount,user_xattr 0 0
/dev/sdd /var/lib/ceph/osd/ceph-2 xfs defaults 0 0
/dev/sdd /var/lib/ceph/osd/ceph-2 xfs remount,user_xattr 0 0

ceph-osd -i 1 --mkfs --mkjournal --mkkey
ceph-osd -i 2 --mkfs --mkjournal --mkkey

7. 注册OSD凭证
ceph auth add osd.0 osd ‘allow *‘ mon ‘allow profile osd‘ -i /var/lib/ceph/osd/ceph-0/keyring
ceph auth add osd.1 osd ‘allow *‘ mon ‘allow profile osd‘ -i /var/lib/ceph/osd/ceph-1/keyring
ceph auth add osd.2 osd ‘allow *‘ mon ‘allow profile osd‘ -i /var/lib/ceph/osd/ceph-2/keyring

iptables -I INPUT 2 -s 30.0.0.0/24 -p tcp -m multiport --dports 6800:6900 -j ACCEPT
iptables-save > /etc/sysconfig/iptables

13. 启动当前节点OSD
/etc/init.d/ceph start osd

14. 查看当前OSD树状态

15. 查看ceph状态

会看到健康状态是HEALTH_WARN,原因是PGs过少,我们来添加

16. 增加PG和PGP数量
ceph osd pool set rbd pg_num 256
ceph osd pool set rbd pgp_num 256
注:如果在执行第二条命令时报Error EBUSY: currently creating pgs, wait,说明第一条命令还没处理完

17. 再次查看ceph状态

与Openstack结合

1. 建立存储池
ceph osd pool create storages 256

2. 建立一个名称为client.storages的凭证,对storages池有操作权限
