cinder-api: Accepts API requests and routes them to cinder-volume for action.[Block Storage services]
cinder-volume: Responds to requests to read from and write to the Block Storage database to maintain state, interacting with other processes
(like cinder-scheduler)[provides storage]
cinder-scheduler daemon: picks the optimal block storage provider node on which to create the volume
Messaging queue: Routes information between the Block Storage service processes.
Controller node:
安裝:
yum install openstack-cinder
建立 DB:
mysql -u root -p
mysql> CREATE DATABASE cinder;
mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'CINDER_DBPASS';
