本文介绍OpenStack Cinder组件的配置过程，包括与Keystone、RabbitMQ及Ceph的连接设置，以及支持的各种块存储类型。

摘要生成于 C知道，由 DeepSeek-R1 满血版支持，前往体验 >

作用

1 cinder 需要连接 ceph 进行云硬盘存储
2 cinder 需要连接 keystone 进行用户验证
3 cinder 需要连接 rabbitmq 处理消息队列

默认下 openstack 提供卷驱动, 支持下面的块存储类型

LVM/iSCSI
ThinLVM
NFS
NetAPP NFS
Red Hat Storage (Gluster)
Dell EqualLogic
CEPH

配置

配置 keystone 验证

# openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_host 240.10.130.25
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_tenant_name service
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_user cinder
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken admin_password cinder
# openstack-config --set /etc/cinder/cinder.conf keystone_authtoken identity_uri  http://240.10.130.25:35357

配置监控端口，地址

# openstack-config --set /etc/cinder/cinder.conf DEFAULT  osapi_volume_listen <你自己IP>
# openstack-config --set /etc/cinder/cinder.conf DEFAULT  osapi_volume_listen_port 8776

数据库配置

# openstack-config --set /etc/cinder/cinder.conf DEFAULT sql_connection mysql://cinder:cinder@240.10.130.25/cinder
# cinder-manage db sync

执行 db sync 之后, 正常会在数据库中看到下面一堆表

mysql> use cinder;
Database changed

mysql> show tables;

配置 cinder 服务配置

cpu 配置

设定 cinder 的进程数量 cores = cpu 个数

# CORES=16
# openstack-config --set /etc/cinder/cinder.conf DEFAULT osapi_volume_workers $CORES

cinder 连接 rabbitmq

设定 rabbitmq 作为 rpc 后台

# openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend cinder.openstack.common.rpc.impl_kombu
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_host <rabbit_mq_server>
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_port <rabbit_mq port>
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_use_ssl false
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_userid cinder
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_userid <cinder_password>
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_login_method AMQPLAIN
# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_virtual_host /
# openstack-config --set /etc/cinder/cinder.conf DEFAULT host <cinder_host>

cinder 连接 rabbitmq 方法

	# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_host 240.10.130.25
	# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_virtual_host /
	# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_port 5672
	# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_userid guest
	# openstack-config --set /etc/cinder/cinder.conf DEFAULT rabbit_password openstack

其他配置

# openstack-config --set /etc/cinder/cinder.conf DEFAULT notification_driver cinder.openstack.common.notifier.rpc_notifier
# openstack-config --set /etc/cinder/cinder.conf DEFAULT control_exchange openstack
# openstack-config --set /etc/cinder/cinder.conf DEFAULT api_paste_config /etc/cinder/api-paste.ini
# openstack-config --set /etc/cinder/cinder.conf DEFAULT glance_host <你的ip>
# openstack-config --set /etc/cinder/cinder.conf DEFAULT backup_topic cinder-backup
# openstack-config --set /etc/cinder/cinder.conf DEFAULT backup_manager cinder.backup.manager.BackupManager
# openstack-config --set /etc/cinder/cinder.conf DEFAULT backup_api_class cinder.backup.api.API
# openstack-config --set /etc/cinder/cinder.conf DEFAULT volume_group cinder-volumes

cinder 与 ceph 连接

基本的 ceph 连接配置

# openstack-config --set /etc/cinder/cinder.conf DEFAULT enabled_backends CEPH_SATA
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA glance_api_version 2
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA volume_backend_name ceph_sata
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_ceph_conf /etc/ceph/ceph-test.conf (ceph 配置)
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_user testyun (ceph 用户)
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_flatten_volume_from_snapshot False
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rados_connect_timeout -1
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_max_clone_depth 5
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA volume_driver cinder.volume.drivers.rbd.RBDDriver
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_store_chunk_size 4
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_secret_uuid 4dc4979a-7dad-4101-9722-20f5917ee133 (ceph 集群 uuid)
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA rbd_pool data (ceph rbd pool)
# openstack-config --set /etc/cinder/cinder.conf CEPH_SATA host ns-yun.vclound.com (对应上面 default 中 host配置)

参考 openstack 管理二十二 - cinder 连接多个存储 backend

注: 默认情况下, 当 cinder 成功使用, 并在创建云硬盘时候, 会自动地连接 ceph, 不需要人为手动挂载

配置 token 验证 (可选, 不影响 cinder create 1)

# openstack-config --set /etc/cinder/api-paste.ini filter:authtoken paste.filter_factory keystoneclient.middleware.auth_token:filter_factory

注: 假如上述 token 不配置, 则在 /var/log/cinder/api.log 中会经常看见下面警告

2014-10-04 15:40:35.830 63155 WARNING keystoneclient.middleware.auth_token [-] Configuring auth_uri to point to the public identity endpoint is required; clients may not be able to authenticate against an admin endpoint
2014-10-04 15:40:35.873 63155 WARNING keystoneclient.middleware.auth_token [-] Configuring auth_uri to point to the public identity endpoint is required; clients may not be able to authenticate against an admin endpoint

而下面警告可忽略, 官方提出这个可能是一个 bug, 并在下一个版本会修复

2014-10-04 15:41:05.370 63170 WARNING cinder.context [-] Arguments dropped when creating context: {'user': None, 'tenant': None, 'user_identity': u'- - - - -'}
2014-10-04 15:42:05.372 63170 WARNING cinder.context [-] Arguments dropped when creating context: {'user': None, 'tenant': None, 'user_identity': u'- - - - -'}
