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-- root root Mar : /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 % .4KB/s :
[root@serverc ~]# scp /etc/ceph/ceph.client.images.keyring ceph@serverb:/etc/ceph/ceph.client.images.keyring
ceph.client.images.keyring % .2KB/s :
[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)]# vim /etc/glance/glance-api.conf
[glance_store]
stores = rbd
default_store = rbd
filesystem_store_datadir = /var/lib/glance/images/

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
-33b2--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 % .3KB/s :
[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: daemons, quorum serverc,serverd,servere
mgr: serverc(active), standbys: serverd, servere
osd: osds: up, in data:
pools: pools, pgs
objects: objects, kB
usage: MB used, GB / GB avail
pgs: 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 =
#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 =
rbd_store_chunk_size =
rados_connect_timeout = -
# 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
-- ::05.800 INFO cinder.volume.manager [req-76edfdb3-dd84--9a4e-de5f79391609 - - - - -] Driver initialization completed successfully.
-- ::05.819 INFO cinder.volume.manager [req-76edfdb3-dd84--9a4e-de5f79391609 - - - - -] Initializing RPC dependent components of volume driver RBDDriver (1.2.)
-- ::05.871 INFO cinder.volume.manager [req-76edfdb3-dd84--9a4e-de5f79391609 - - - - -] Driver post RPC initialization completed successfully.

-- ::30.474 INFO cinder.volume.manager [req-ba2a8ef1-e3f0-4a36-a0eb-5a300367c60c - - - - -] Driver post RPC 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
+---------------------+--------------------------------------+
| Field | Value |
+---------------------+--------------------------------------+
| attachments | [] |

| properties | |
| replication_status | disabled |
| size | |
| snapshot_id | None |

| type | None |
| updated_at | None |
| user_id | 8e0be34493e04722ba03ab30fbbf3bf8 |
+---------------------+--------------------------------------+
2.9 确认验证
[root@serverb ~(keystone_admin)]# openstack volume list -c ID -c 'Display Name' -c Status -c Size
+--------------------------------------+--------------+-----------+------+
| ID | Display Name | Status | Size |
+--------------------------------------+--------------+-----------+------+

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

2.10 删除操作
[root@serverb ~(keystone_admin)]# openstack volume delete testvolume
[root@serverb ~(keystone_admin)]# openstack volume list
