OpenStack kilo版(8) 部署cinder
直接将cinder服务和块设备都部署在controller节点上
在controller节点添加一块100G的块设备/dev/sdb
配置数据库
(root@localhost) [(none)]> CREATE DATABASE cinder;
Query OK, 1 row affected (0.02 sec)
(root@localhost) [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.10 sec)
(root@localhost) [(none)]> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'cinder';
Query OK, 0 rows affected (0.00 sec)
(root@localhost) [(none)]> flush privileges ;
Query OK, 0 rows affected (0.04 sec)
配置cinder服务认证
创建cinder用户：
root@controller:~# openstack user create --password-prompt cinder
User Password:cinder
Repeat User Password:cinder
+----------+----------------------------------+
| Field | Value |
+----------+----------------------------------+
| email | None |

创建cinder的服务实体：
root@controller:~# openstack service create --name cinder --description "OpenStack Block Storage" volume
+-------------+----------------------------------+
| Field | Value |
+-------------+----------------------------------+

+-------------+----------------------------------+
创建cinder服务的API endpoint：
root@controller:~# openstack endpoint create --publicurl http://controller:8776/v2/%\(tenant_id\)s --internalurl http://controller:8776/v2/%\(tenant_id\)s --adminurl http://controller:8776/v2/%\(tenant_id\)s --region RegionOne volume

+--------------+-----------------------------------------+
安装cinder-server
root@controller:~# apt-get install cinder-api cinder-scheduler python-cinderclient cinder-volume
配置cinder-server
[DEFAULT]
rpc_backend = rabbit
auth_strategy = keystone
my_ip = 10.0.0.200
[database]
connection = mysql://cinder:cinder@controller/cinder
[oslo_messaging_rabbit]
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = openstack
[keystone_authtoken]
auth_uri = http://controller:5000

auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = cinder
password = cinder
[oslo_concurrency]
lock_path = /var/lock/cinder
初始化数据库：
root@controller:~# su -s /bin/sh -c "cinder-manage db sync" cinder
重启服务：
root@controller:~# service cinder-scheduler restart
cinder-scheduler stop/waiting
cinder-scheduler start/running, process 5420
root@controller:~# service cinder-api restart
cinder-api stop/waiting
cinder-api start/running, process 5444
删除Ubuntu自带的SQLit数据库：
root@controller:~# rm -f /var/lib/cinder/cinder.sqlite
块存储配置
创建新分区：将sdb整块盘建立一个分区：
root@controller:~# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0x622b5756.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): n

The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
配置LVM的物理卷：
root@controller:~# pvcreate /dev/sdb1
Physical volume "/dev/sdb1" successfully created
root@controller:~# pvdisplay
--- Physical volume ---
PV Name /dev/sdb1
VG Name cinder-volumes
PV Size 100.00 GiB / not usable 3.00 MiB
Allocatable yes
PE Size 4.00 MiB
Total PE 25599
Free PE 25599
Allocated PE 0
PV UUID bLnc53-Yv3d-samm-nGLL-riM8-TyJc-xQn0i5
创建LVM的卷组cinder-volumes：
root@controller:~# vgcreate cinder-volumes /dev/sdb1
Volume group "cinder-volumes" successfully created
root@controller:~# vgdisplay
--- Volume group ---
VG Name cinder-volumes
System ID

Metadata Areas 1
Metadata Sequence No 1
VG Access read/write
VG Status resizable
MAX LV 0
Cur LV 0
Open LV 0
Max PV 0
Cur PV 1
Act PV 1
VG Size 100.00 GiB
PE Size 4.00 MiB
Total PE 25599
Alloc PE / Size 0 / 0
Free PE / Size 25599 / 100.00 GiB
VG UUID B623Af-5Uru-0S81-23Cr-XOZt-ZCkq-Wh42sf
配置LVM仅仅扫描含有cinder-volume的卷组
编辑/etc/lvm/lvm.conf，在devices部分，添加一个筛选器，仅仅允许/dev/sdb设备并拒绝所有其他设备：
devices {
...
filter = [ "a/sdb/", "r/.*/"]
安装cinder
由于都部署在controller节点上，可以忽略这步
root@controller:~# apt-get install -y cinder-volume python-mysqldb
配置cinder
/etc/cinder/cinder.conf 添加：
[DEFAULT]
#启用LVM作为后端存储系统
enabled_backends = lvm
#镜像服务运行的节点
glance_host = controller
#配置LVM驱动，卷组，iscsi的协议和helper：
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = tgtadm
重启服务：
root@controller:~# service tgt restart
tgt stop/waiting
tgt start/running, process 3785
root@controller:~# service cinder-volume restart
cinder-volume stop/waiting
cinder-volume start/running, process 3838
检查块存储服务启动的服务组件：
root@controller:~# cinder service-list
