020 ceph作openstack的后端存储
一、使用ceph做glance后端
1.1 创建用于存储镜像的池
[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'
1.2 创建client.glance账号并授权
[root@serverc ~]# ceph auth get-or-create client.glance mon 'allow r' osd 'allow class-read object_prefix rbd_children,allow rwx pool=images' -o /etc/ceph/ceph.client.glance.keyring
[root@serverc ~]# ll /etc/ceph/ceph.client.glance.keyring
-rw-r--r-- 1 root root 64 Mar 31 10:33 /etc/ceph/ceph.client.glance.keyring
1.3 在glance服务器上安装ceph客户端
[root@serverb ~]# yum -y install ceph-common
从ceph服务端将ceph.conf以及ceph.client.glance.keyring复制到glance服务器
[root@serverc ceph]# scp -r /etc/ceph/ceph.conf /etc/ceph/ceph.client.glance.keyring serverb:/etc/ceph/
ceph.conf 100% 1262 2.5MB/s 00:00 ceph.client.glance.keyring 100% 64 153.1KB/s 00:00
1.4 在客户端修改相关权限
[root@serverb ~]# chown glance.glance /etc/ceph/ceph.client.glance.keyring
1.5 修改配合文件
修改客户端的/etc/ceph/ceph.conf
[root@serverb ~]# vim /etc/ceph/ceph.conf
[client.glance] keyring = /etc/ceph/ceph.client.glance.keyring
修改/etc/glance/glance-api.conf
[glance_store] stores = rbd default_store = rbd filesystem_store_datadir = /var/lib/glance/images/ rbd_store_chunk_size = 8 rbd_store_pool = images rbd_store_user = glance rbd_store_ceph_conf = /etc/ceph/ceph.conf os_region_name=RegionOne
[root@serverb ~]# grep -Ev "^$|^[#;]" /etc/glance/glance-api.conf
[DEFAULT] bind_host = 0.0.0.0 bind_port = 9292 workers = 2 image_cache_dir = /var/lib/glance/image-cache registry_host = 0.0.0.0 debug = False log_file = /var/log/glance/api.log log_dir = /var/log/glance [cors] [cors.subdomain] [database] connection = mysql+pymysql://glance:27c082e7c4a9413c@172.25.250.11/glance [glance_store] stores = rbd default_store = rbd filesystem_store_datadir = /var/lib/glance/images/ rbd_store_chunk_size = 8 rbd_store_pool = images rbd_store_user = glance rbd_store_ceph_conf = /etc/ceph/ceph.conf os_region_name=RegionOne [image_format] [keystone_authtoken] auth_uri = http://172.25.250.11:5000/v2.0 auth_type = password project_name=services username=glance password=99b29d9142514f0f auth_url=http://172.25.250.11:35357 [matchmaker_redis] [oslo_concurrency] [oslo_messaging_amqp] [oslo_messaging_notifications] [oslo_messaging_rabbit] [oslo_messaging_zmq] [oslo_middleware] [oslo_policy] policy_file = /etc/glance/policy.json [paste_deploy] flavor = keystone [profiler] [store_type_location_strategy] [task] [taskflow_executor]
重启glance-api
[root@serverb ~]# systemctl restart openstack-glance-api
1.6 验证
下载镜像
[root@foundation ~]# wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img

二、 使用ceph作为cinder后端

+----+--------+------+------+-------------+----------+-------------+ | ID | Status | Name | Size | Volume Type | Bootable | Attached to | +----+--------+------+------+-------------+----------+-------------+ +----+--------+------+------+-------------+----------+-------------+
2.1 为cinder也创建一个rbd池
[root@serverc ~]# ceph osd pool create volumes 64 64
pool 'volumes' created
[root@serverc ~]# ceph osd pool application enable volumes rbd
enabled application 'rbd' on pool 'volumes'
2.2 为client.cinder用户授权
[root@serverc ~]# ceph auth get-or-create client.cinder mon 'allow r' osd 'allow class-read object_prefix rbd_children, allow rwx pool=images, allow rwx pool=volumes' -o /etc/ceph/ceph.client.cinder.keyring
[root@serverc ~]# ceph auth get-key client.cinder -o /etc/ceph/temp.client.cinder.key
[root@serverc ~]# cat /etc/ceph/temp.client.cinder.key
AQA5KaBcszk/JxAAPdymqbMzqrfhZ+GyqZgUvg==
[root@serverc ~]# scp -r /etc/ceph/ceph.client.glance.keyring /etc/ceph/ceph.client.cinder.keyring serverb:/etc/ceph/
root@serverb's password: ceph.client.glance.keyring 100% 64 185.6KB/s 00:00 ceph.client.cinder.keyring 100% 64 89.5KB/s 00:00
2.3 在cinder服务器上安装ceph的客户端
[root@serverb ~]# yum -y install ceph-commom
[root@serverb tmp]# chown cinder.cinder -R /etc/ceph/ceph.client.cinder.keyring
2.4 修改客户端/etc/ceph/ceph.conf
[root@serverb tmp]# vim /etc/ceph/ceph.conf
[client.cinder] keyring = /etc/ceph/ceph.client.cinder.keyring
2.5 生成libvirt的secret
[root@serverb tmp(keystone_admin)]# uuidgen
ade72e47-ce6f-4f44-a97d-d7dff6aef99c
[root@serverb tmp(keystone_admin)]# vim /etc/ceph/secret.xml

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

UUID Usage --------------------------------------------------------------------------------ade72e47-ce6f-4f44-a97d-d7dff6aef99c ceph client.cinder secret
2.6 将密钥设置到secret中
[root@serverb tmp(keystone_admin)]# virsh secret-set-value --secret ade72e47-ce6f-4f44-a97d-d7dff6aef99c --base64 $(cat /etc/ceph/temp.client.cinder.key)

2.7 修改 /etc/cinder/cinder.conf
[root@serverb tmp(keystone_admin)]# vim /etc/cinder/cinder.conf
[DEFALUT] enabled_backends = rbd2 default_volume_type = rbd2 glance_api_version = 2[rbd2] volume_driver = cinder.volume.drivers.rbd.RBDDriver rbd_pool = volumes rbd_user = cinder rbd_ceph_conf = /etc/ceph/ceph.conf rbd_flatten_volume_from_snapshot = false rbd_secret_uuid = f50719e8-e5b7-404e-980a-c80254e4541c 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 = rbd2
2.8 创建指定的cinder的volume类型
[root@serverb tmp(keystone_admin)]# cinder type-create rbd2
+--------------------------------------+------+-------------+-----------+ | ID | Name | Description | Is_Public | +--------------------------------------+------+-------------+-----------+ | c92590e9-33f8-4152-8853-945dc3eb4548 | rbd2 | - | True | +--------------------------------------+------+-------------+-----------+

[root@serverb tmp(keystone_admin)]# systemctl restart openstack-cinder-api
[root@serverb tmp(keystone_admin)]# systemctl restart openstack-cinder-scheduler
2.9 验证
[root@serverb tmp(keystone_admin)]# cinder create --name new-volume --display-name 'ceph storage' 2 --volume_type rbd2

三、使用keystone验证rados网关
3.1 配置rados服务器端
[root@serverc ~]# yum install -y ceph-radosgw
[root@serverc ~]# ceph auth get-or-create client.rgw.serverc mon 'allow rwx' osd 'allow rwx' -o /etc/ceph/ceph.client.rgw.serverc.keyring
[root@serverc ~]# vim /etc/ceph/ceph.conf
[root@serverc ~]# systemctl restart ceph-radosgw@rgw.serverc
[root@serverc ~]# ps -ef|grep rados
root 46163 1 0 11:19 ? 00:00:00 /usr/bin/radosgw -f --cluster ceph --name client.rgw.serverc --setuser ceph --setgroup ceph
3.2 在keystone上创建服务与端点
[root@serverb tmp(keystone_admin)]# openstack service create --description "Swift Service" --name swift object-store
+-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | Swift Service | | enabled | True | | id | 1dd0d40cd61d4bed870cc3c302a001da | | name | swift | | type | object-store | +-------------+----------------------------------+

3.3 获取keystone admin token
[root@serverb tmp(keystone_admin)]# cat /etc/keystone/keystone.conf |grep admin_token
# value is ignored and the `admin_token` middleware is effectively disabled. # However, to completely disable `admin_token` in production (highly # `AdminTokenAuthMiddleware` (the `admin_token_auth` filter) from your paste #admin_token = <None> admin_token = fb032ccf285a432b81c6fe347be8a07d
3.4 修改 /etc/ceph/ceph.conf
[root@serverc ~]# vim /etc/ceph/ceph.conf
