cinder-api： 接受和响应外部有关块存储请求
cinder-volume： 提供存储空间
cinder-scheduler: 调度器，决定将要分配的空间由哪一个cinder-volume提供
cinder-backup: 备份存储
1、数据库创库授权
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \
IDENTIFIED BY 'CINDER_DBPASS';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \
IDENTIFIED BY 'CINDER_DBPASS';
2、在keystone创建系统用户（glance，nova，neutron）关联角色
openstack user create --domain default --password CINDER_PASS cinder
openstack role add --project service --user cinder admin
3、在keystone上创建服务和注册api
openstack service create --name cinder \
--description "OpenStack Block Storage" volume
openstack service create --name cinderv2 \
--description "OpenStack Block Storage" volumev2
openstack endpoint create --region RegionOne \
volume public http://controller:8776/v1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
volume internal http://controller:8776/v1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
volume admin http://controller:8776/v1/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
volumev2 public http://controller:8776/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
volumev2 internal http://controller:8776/v2/%\(tenant_id\)s
openstack endpoint create --region RegionOne \
volumev2 admin http://controller:8776/v2/%\(tenant_id\)s
4、安装服务相应的软件包
5、修改相应服务的配置文件
openstack-config --set /etc/cinder/cinder.conf DEFAULT rpc_backend rabbit
openstack-config --set /etc/cinder/cinder.conf DEFAULT auth_strategy keystone
openstack-config --set /etc/cinder/cinder.conf DEFAULT my_ip 10.0.0.11
openstack-config --set /etc/cinder/cinder.conf database connection mysql+pymysql://cinder:[email protected]/cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_uri http://controller:5000
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_url http://controller:35357
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken memcached_servers controller:11211
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken auth_type password
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken user_domain_name default
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken project_name service
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken username cinder
openstack-config --set /etc/cinder/cinder.conf keystone_authtoken password CINDER_PASS
openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_host controller
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_userid openstack
openstack-config --set /etc/cinder/cinder.conf oslo_messaging_rabbit rabbit_password RABBIT_PASS
6、同步数据库
su -s /bin/sh -c "cinder-manage db sync" cinder
vim /etc/nova/nova.conf
[cinder] os_region_name = RegionOne
7、启动服务
systemctl restart openstack-nova-api.service
systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl start openstack-cinder-api.service openstack-cinder-scheduler.service
在存储节点上：（在控制节点也可以 ，这里安装在控制节点）
（LVM性能不如标准分区，优点是可以随时扩展分区大小）
LVM逻辑卷：
先决条件
systemctl start lvm2-lvmetad.service
扫描
fdisk -l 查看
创建物理卷
pvcreate /dev/sdb
pvcreate /dev/sdc
创建卷组
vgcreate cinder-ssd /dev/sdb
vgcreate cinder-sata /dev/sdc
vim /etc/lvm/lvm.conf
devices { ... filter = [ "a/sdb/", "a/sdc","r/.*/"]
在130行下加入
filter = [ "a/sdb/", "a/sdc/","r/.*/"]
安装配置组件
yum install openstack-cinder targetcli python-keystone -y
