019 Ceph整合openstack

一、整合 glance ceph

1.1 查看servverb关于openstack的用户

[root@serverb ~]# vi ./keystonerc_admin

unset OS_SERVICE_TOKEN
export OS_USERNAME=admin
export OS_PASSWORD=9f0b699989a04a05
export OS_AUTH_URL=http://172.25.250.11:5000/v2.0
export PS1='[u@h W(keystone_admin)]$ '
export OS_TENANT_NAME=admin
export OS_REGION_NAME=RegionOne

[root@serverb ~(keystone_admin)]# openstack service list

1.2 安装ceph包

[root@serverb ~(keystone_admin)]# yum -y install ceph-common

[root@serverb ~(keystone_admin)]# chown ceph:ceph /etc/ceph/

1.3 创建RBD镜像

root@serverc ~]#  ceph osd pool create images 128 128

pool 'images' created

[root@serverc ~]# ceph osd pool application enable images rbd

enabled application 'rbd' on pool 'images'

[root@serverc ~]# ceph osd pool ls

images

1.4创建Ceph池用户

[root@serverc ~]# ceph auth get-or-create client.images mon 'profile rbd' osd 'profile rbd pool=images' -o /etc/ceph/ceph.client.images.keyring

[root@serverc ~]# ll /etc/ceph/ceph.client.images.keyring

-rw-r--r-- 1 root root 64 Mar 30 14:18 /etc/ceph/ceph.client.images.keyring

[root@serverc ~]# ceph auth list|grep -A 4 images

1.5 复制到serverb节点并验证

[root@serverc ~]# scp /etc/ceph/ceph.conf ceph@serverb:/etc/ceph/ceph.conf

ceph.conf                                                                              100%  470   725.4KB/s   00:00 

 [root@serverc ~]# scp /etc/ceph/ceph.client.images.keyring  ceph@serverb:/etc/ceph/ceph.client.images.keyring

ceph.client.images.keyring                                                             100%   64   145.2KB/s   00:00   

[root@serverb ~(keystone_admin)]# ceph --id images -s

1.6 修改秘钥环权限

[root@serverb ~(keystone_admin)]# chgrp glance /etc/ceph/ceph.client.images.keyring

[root@serverb ~(keystone_admin)]# chmod 0640 /etc/ceph/ceph.client.images.keyring

1.7 修改glance后端存储

[root@serverb ~(keystone_admin)]# systemctl restart openstack-glance-api

1.8 创建image测试

1.9 删除一个镜像操作

[root@serverb ~(keystone_admin)]# openstack image delete "Small Image"

[root@serverb ~(keystone_admin)]# openstack image list

[root@serverb ~(keystone_admin)]# rbd --id images -p images ls

14135e67-39bb-4b1c-aa11-fd5b26599ee7
42030515-33b2-4875-8b63-119a0dbc12d4

[root@serverb ~(keystone_admin)]# ceph osd pool ls --id images

images  

 二、整合ceph和cinder

2.1 创建RBD镜像

[root@serverc ~]# ceph osd pool create volumes 128

pool 'volumes' created

[root@serverc ~]# ceph osd pool application  enable volumes  rbd

enabled application 'rbd' on pool 'volumes'

2.2 创建ceph用户

[root@serverc ~]# ceph auth get-or-create client.volumes mon 'profile rbd' osd 'profile rbd pool=volumes,profile rbd pool=images' -o /etc/ceph/ceph.client.volumes.keyring

[root@serverc ~]# ceph auth list|grep -A 4 volumes

installed auth entries:

client.volumes
    key: AQBOEZ9ckRr3BxAAaWB8lpYRrUQ+z/Bgk3Rfbg==
    caps: [mon] profile rbd
    caps: [osd] profile rbd pool=volumes,profile rbd pool=images
mgr.serverc
    key: AQAKu55cKGFlHBAAXjlvu2GFiJXUQx04PcidgA==
    caps: [mds] allow *
    caps: [mon] allow profile mgr

2.3 复制到serverb节点

[root@serverc ~]# scp /etc/ceph/ceph.client.volumes.keyring ceph@serverb:/etc/ceph/ceph.client.volumes.keyring

ceph@serverb's password: 
ceph.client.volumes.keyring                                                              100%   65   108.3KB/s   00:00

[root@serverc ~]# ceph auth  get-key client.volumes|ssh ceph@serverb tee ./client.volumes.key

ceph@serverb's password: 
AQBOEZ9ckRr3BxAAaWB8lpYRrUQ+z/Bgk3Rfbg==[root@serverc ~]# 

2.3 serverb节点确认验证

[root@serverb ~(keystone_admin)]# ceph --id volumes -s

  cluster:
    id:     2d58e9ec-9bc0-4d43-831c-24b345fc2a94
    health: HEALTH_OK
 
  services:
    mon: 3 daemons, quorum serverc,serverd,servere
    mgr: serverc(active), standbys: serverd, servere
    osd: 9 osds: 9 up, 9 in
 
  data:
    pools:   2 pools, 256 pgs
    objects: 14 objects, 25394 kB
    usage:   1048 MB used, 133 GB / 134 GB avail
    pgs:     256 active+clean

2.4 修改秘钥环权限

[root@serverb ~(keystone_admin)]# chgrp cinder /etc/ceph/ceph.client.volumes.keyring

[root@serverb ~(keystone_admin)]# chmod 0640 /etc/ceph/ceph.client.volumes.keyring

2.5 生成uuid

[root@serverb ~(keystone_admin)]# uuidgen |tee ~/myuuid.txt

f3fbcf03-e208-4fba-9c47-9ff465847468

2.6 修改cinder后端存储

[root@serverb ~(keystone_admin)]# vi /etc/cinder/cinder.conf 

enabled_backends = ceph
glance_api_version = 2
#default_volume_type = iscsi

[ceph]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rbd_pool = volumes
rbd_user = volumes
rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_flatten_volume_from_snapshot = false
rbd_secret_uuid = f3fbcf03-e208-4fba-9c47-9ff465847468
rbd_max_clone_depth = 5
rbd_store_chunk_size = 4
rados_connect_timeout = -1
# 指定volume_backend_name，可忽略
volume_backend_name = ceph 

2.7 启动并查看日志

[root@serverb ~(keystone_admin)]# systemctl restart openstack-cinder-api

[root@serverb ~(keystone_admin)]# systemctl restart openstack-cinder-volume

[root@serverb ~(keystone_admin)]# systemctl restart openstack-cinder-scheduler

[student@serverb ~]$ sudo tail -20 /var/log/cinder/volume.log

2019-03-30 15:11:05.800 23646 INFO cinder.volume.manager [req-76edfdb3-dd84-4377-9a4e-de5f79391609 - - - - -] Driver initialization completed successfully.

2.8 创建XML模板

[root@serverb ~(keystone_admin)]# vim ~/ceph.xml

<secret ephemeral="no" private="no">
  <uuid>f3fbcf03-e208-4fba-9c47-9ff465847468</uuid>
  <usage type="ceph">
    <name>client.volumes secret</name>
  </usage>
</secret>

[root@serverb ~(keystone_admin)]# virsh secret-define --file ~/ceph.xml

Secret f3fbcf03-e208-4fba-9c47-9ff465847468 created

[root@serverb ~(keystone_admin)]# virsh secret-set-value --secret f3fbcf03-e208-4fba-9c47-9ff465847468 --base64 $(cat /home/ceph/client.volumes.key)

Secret value set

2.9 创建volume卷测试

[root@serverb ~(keystone_admin)]# openstack volume create --description "Test Volume" --size 1 testvolume
