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

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

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

cinder 与 ceph 连接

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

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
