Openstack-之cinder

教程大纲

                      到今天咱们的分享已经完成目标了！

1. cinder安装
2. cinder界面建立云硬盘

1.建立cinder数据库

mysql -u root -p -e "create database cinder;"

mysql -u root -p -e "grant all on cinder.* to cinder@localhost identified by 'cinder';"

mysql -u root -p -e "grant all on cinder.* to cinder@'%' identified by 'cinder';"

2.安装cinder组件

yum install openstack-cinder

3.配置cinder配置文件

[database]

connection = mysql://cinder:cinder@192.168.100.40/cinder

 同步数据库

 su -s /bin/sh -c "cinder-manage db sync" cinder

验证数据库  mysql -u cinder -p cinder -e "use cinder;show tables"

[DEFAULT]

rpc_backend = rabbit

【RabbitMQ】

[oslo_messaging_rabbit]

...

rabbit_host = 192.168.100.40

rabbit_userid = openstack

rabbit_password = openstack

【keystone】

[DEFAULT]

auth_strategy = keystone

[keystone_authtoken]

auth_uri = http://192.168.100.40:5000

auth_url = http://192.168.100.40:35357

memcached_servers = 192.168.100.40:11211

auth_type = password

project_domain_name = default

user_domain_name = default

project_name = service

username = cinder

password = cinder

4.修改Nova的配置文件/etc/nova/nova.conf

[cinder]

os_region_name = RegionOne

5.建立cinder的用户

. admin-openrc

3.1建立cinder用户
openstack user create --domain default --password-prompt cinder

3.2添加 admin 角色到 cinder 用户上。
openstack role add --project service --user cinder admin

3.3建立 cinder 和 cinderv2 服务实体：
openstack service create --name cinder \
  --description "OpenStack Block Storage" volume

  openstack service create --name cinderv2 \
  --description "OpenStack Block Storage" volumev2

11.建立块设备存储服务的 API 入口点：

 openstack endpoint create --region RegionOne \

  volume public http://192.168.100.40:8776/v1/%\(tenant_id\)s

 openstack endpoint create --region RegionOne \

  volume internal http://192.168.100.40:8776/v1/%\(tenant_id\)s

 

 openstack endpoint create --region RegionOne \

  volume admin http://192.168.100.40:8776/v1/%\(tenant_id\)s

  openstack endpoint create --region RegionOne \

  volumev2 public http://192.168.100.40:8776/v2/%\(tenant_id\)s

  openstack endpoint create --region RegionOne \

  volumev2 internal http://192.168.100.40:8776/v2/%\(tenant_id\)s

  openstack endpoint create --region RegionOne \

  volumev2 admin http://192.168.100.40:8776/v2/%\(tenant_id\)s

13. 重启服务Nova-api 和cinder服务

重启Nova-api 服务

systemctl restart openstack-nova-api.service

启动服务cinder

systemctl enable openstack-cinder-api.service openstack-cinder-scheduler.service

systemctl restart openstack-cinder-api.service openstack-cinder-scheduler.service

14.计算节点的cinder网络组件

 yum install openstack-cinder targetcli python-keystone

15.node2上添加一块磁盘：（关机后）

16.建立lvm逻辑卷 

建立LVM 物理卷 /dev/sdb：

 pvcreate /dev/sdb

建立 LVM 卷组 cinder-volumes：

vgcreate cinder-volumes /dev/sdb

修改lvm的配置/etc/lvm/lvm.conf

devices {

...

filter = [ "a/sdb/", "r/.*/"]

17.修改node2上的cinder配置

/etc/cinder/cinder.conf

[DEFAULT]

...

enabled_backends = lvm  启用 LVM 后端：

手动添加如下［ lvm］

[lvm]

volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver

volume_group = cinder-volumes

iscsi_protocol = iscsi

iscsi_helper = lioadm

16.重启cinder node2节点服务

启动服务：

systemctl enable openstack-cinder-volume.service target.service

systemctl restart openstack-cinder-volume.service target.service

16.测试查看

验证：

$ . admin-openrc

cinder service-list
