cinder 就是云硬盘

配置cinder步骤

1 安装软件包，然后到keystone注册

创建必要的用户名密码

服务

endpoint

2 设置配置文件

yum install openstack-cinder  -y
keystone  user-create  --name  cinder  --pass  hequan
keystone  user-role-add --user   cinder  --role admin  --tennat  services

keystone  service-create  --name  cinder  --type volume  --description  cinderxxx
 
例子  关于cul
keystone service-list 
| d1271040fa9144318a836a0b476d1e66 |   cinder   |    volume    |         Cinder Service         |

keystone  endpoint-list  | grep   d1271040fa9144318a836a0b476d1e66

| 8e18c46fc51c4a6287ea740a37537a59 | RegionOne |    http://115.29.107.17:8776/v1/%(tenant_id)s   |    http://115.29.107.17:8776/v1/%(tenant_id)s   | http://115.29.107.17:8776/v1/%(tenant_id)s | d1271040fa9144318a836a0b476d1e66 |
 
keystone  endpoint-create --service-id   d1271040fa9144318a836a0b476d1e66  --publicul 'http://115.29.107.17:8776/v1/%(tenant_id)s'  --internalurl 'http://115.29.107.17:8776/v1/%(tenant_id)s' --adminurl 'http://115.29.107.17:8776/v1/%(tenant_id)s'
 
[root@hequan ~(keystone_admin)]# cd /etc/cinder/
 
[root@hequan cinder(keystone_admin)]# ls

api-paste.ini  policy.json    rootwrap.d
cinder.conf    rootwrap.conf  volumes
 
[root@hequan cinder(keystone_admin)]# cp cinder.conf cinder.conf.bak  ##备份

[root@hequan ~(keystone_admin)]# cp /usr/share/cinder/cinder-dist.conf  /etc/cinder/cinder.conf   ##复制配置文件

[root@hequan cinder(keystone_admin)]# chown root.cinder  cinder.conf  ##记得修改权限

[root@hequan cinder(keystone_admin)]# openstack-db --init -service cinder  --password hequan  --rootpw 123456  ##创建数据库

[root@hequan cinder(keystone_admin)]# vim cinder.conf
[DEFAULT]

logdir = /var/log/cinder

state_path = /var/lib/cinder

lock_path = /var/lib/cinder/tmp

volumes_dir = /etc/cinder/volumes
iscsi_helper = lioadm

rootwrap_config = /etc/cinder/rootwrap.conf
auth_strategy = keystone
[database]

connection = mysql://cinder:hequan@115.29.107.17/cinder
[keystone_authtoken]
admin_tenant_name = services
admin_user = cinder
admin_password = hequan
auth_host = 115.29.107.17
auth_port = 35357
auth_protocol = http
 
[root@hequan cinder(keystone_admin)]# grep ^rabbit  /etc/keystone/keystone.conf
rabbit_host = localhost
rabbit_port = 5672
rabbit_hosts = localhost:5672
rabbit_use_ssl = False
rabbit_userid = guest
rabbit_password = guest
rabbit_virtual_host = /

rabbit_ha_queues = False   ##把这些写到上面的配置文件里，通信用
 
[root@hequan cinder(keystone_admin)]# systemctl  list-unit-files  | grep cinder

openstack-cinder-api.service                  enabled   ##用户接口

openstack-cinder-backup.service               enabled   ##备份

openstack-cinder-scheduler.service            enabled   ##调度

openstack-cinder-volume.service               enabled    ##后端存储 卷

[root@hequan cinder(keystone_admin)]# systemctl  is-active  openstack-cinder-api.service
active

[root@hequan cinder(keystone_admin)]# systemctl start openstack-cinder-api.service  openstack-cinder-backup.service  openstack-cinder-scheduler.service openstack-cinder-volume.service

[root@hequan cinder(keystone_admin)]# systemctl enable  openstack-cinder-api.service  openstack-cinder-backup.service  openstack-cinder-scheduler.service openstack-cinder-volume.service  
 
再创建一个cinderv2  和上面一样
| 8fe36f49892447679bc5433b21591906 |  cinderv2  |   volumev2   |       Cinder Service v2        |

| 75a8f5bbf35a42a0bfcd2e6a0d4cea9c | RegionOne |    http://115.29.107.17:8776/v2/%(tenant_id)s   |    http://115.29.107.17:8776/v2/%(tenant_id)s   | http://115.29.107.17:8776/v2/%(tenant_id)s | 8fe36f49892447679bc5433b21591906 |

2 修改配置

[root@hequan cinder(keystone_admin)]# cinder list

创建VG

##添加到上面的配置 cinder.conf中  作为单独字段
 
[lvm]
iscsi_helper=lioadm

volume_group=cinder-volumes    ##那个组决定默认存储
iscsi_ip_address=115.29.107.17

volume_driver=cinder.volume.drivers.lvm.LVMVolumeDriver  ##云硬盘默认存储LVM

volumes_dir=/var/lib/cinder/volumes
iscsi_protocol=iscsi
volume_backend_name=lvm
 
[root@hequan cinder(keystone_admin)]# lvs

  LV                                          VG             Attr       LSize  Pool Origin Data%  Meta%  Move Log Cpy%Sync Convert                                        

  volume-7f778803-41cd-492f-b3b7-baa349b9c3dc cinder-volumes -wi-a-----  1.00g 
 
  [root@hequan cinder(keystone_admin)]# lvscan

  ACTIVE            '/dev/cinder-volumes/volume-7f778803-41cd-492f-b3b7-baa349b9c3dc' [1.00 GiB] inherit

更换名字
volume_group=vg0

[root@hequan cinder(keystone_admin)]# vgrename  cinder-volumes vg0       ##更改名字

[root@hequan ~]# vgs

  VG   #PV #LV #SN Attr   VSize  VFree

  vg0    1   2   0 wz--n- 20.60g 9.60g

待测试 ceph做后端存储  具体ceph配置 可看我前一篇glance
volume_driver = cinder.volume.drivers.rbd.RBDDriver

rbd_pool = cinder  #ceph 卷名字

rbd_ceph_conf = /etc/ceph/ceph.conf

rbd_flatten_volume_from_snapshot = false
rbd_max_clone_depth = 5
rbd_stone_chunk_size = 4
rados_connect_timeout = -1
glance_api_version = 2
 

setfacl  -m   u:cinder:r--   /etc/ceph/ceph.client.admin.keyring  ##cinder可读
