3.配置控制节点
操作对象：控制节点
3.1.创建cinder数据库及用户
# mysql -u root -p
> CREATE DATABASE cinder;
> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'root';
> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'root';
> flush privileges;
3.2.创建Cinder服务凭证
#在default域创建用户cinder
# source admin-openrc
# openstack user create --domain default --password-prompt cinder
User Password:
#绑定用户cinder为admin角色
# openstack role add --project service --user cinder admin
#创建cinderv2和cinderv3服务实体
# openstack service create --name cinderv2 --description "Openstack Block Storage" volumev2
# openstack service create --name cinderv3 --description "Openstack Block Storage" volumev3
3.3.创建存储API服务端点
# openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)s
# openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s
# openstack endpoint list --service cinderv2
+----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------------------+

| e187fbcd8aed4815941638479dba9684 | RegionOne | cinderv2 | volumev2 | True | public | http://controller:8776/v2/%(project_id)s |
+----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------------------+
# openstack endpoint list --service cinderv3
+----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------------------+
| ID | Region | Service Name | Service Type | Enabled | Interface | URL |
+----------------------------------+-----------+--------------+--------------+---------+-----------+------------------------------------------+

| b00739ead70245bf83b92bf7ec4a181d | RegionOne | cinderv3 | volumev3 | True | public | http://controller:8776/v3/%(project_id)s |
| d528b8fd3eda4abb8f9c67836d2be6c5 | RegionOne | cinderv3 | volumev3 | True | internal | http://controller:8776/v3/%(project_id)s |

+------------------+----------------+------+---------+-------+----------------------------+
| cinder-scheduler | controller | nova | enabled | up | 2022-09-17T09:12:52.000000 |
| cinder-volume | computehci@lvm | nova | enabled | up | 2022-09-17T09:12:56.000000 |
| cinder-backup | computehci | nova | enabled | up | 2022-09-17T09:12:54.000000 |
+------------------+----------------+------+---------+-------+----------------------------+
如果status不为up，而为down的话，可以检查各个节点的时间同步状态，一般是时间不同步的原因造成。
