Dashboard.Open the Volume management interfaceClick the drop-down arrow and the list is the action that CINDER-API can perform.Cinder-schedulerWhen Volume is created, Cinder-scheduler chooses the most appropriate storage node based on conditions such as capacity, Volume Type, and then lets it create Volume.This section is much more, and we'll discuss it separately next time.Cinder-volumeThe cinder-volume runs on the

Instance, and the compute node itself is working properly. If the compute node fails, OpenStack cannot communicate with the node's nova-compute, and all instance running on it will be affected. At this point, the Instance can only be rebuilt on other normal nodes through the evacuate operation.EvacuateRebuilds Instance on other compute nodes using the Instance image file on the shared storage. So planning

traffic, such as whether the need for gigabit network card, the cost of the deployment is quite large, need not network physical separation, a few million, or all million, need to be evaluated according to traffic. For example, in an environment mgmt and storage traffic presumably is not small, equipped with the million Gigabit network card is the brunt. Then the north-south flow of public and east-west traffic to the private this is to be evaluated

communication and collaboration through Message Queuing. This loosely structured structure is also an important feature of distributed systems because of the message queue and the decoupling of the sub-service implementations.Database Cinder Some data need to be stored in the database, generally use MySQL. The database is installed on the control node, for example, in our experimental environment, a database named "Cinder" can be accessed.Physical Deployment ScenariosCinder services are deploye

Nova is a compute service that can start a virtual machine instance. These services can be configured on a separate node or on the same node. Most services run on the controller node and run the virtual machine service on a dedicated compute node. This time, we deploy the compute to the control node.4.1 Install Compute Controller services (Installation Compute service)4.1.1 installation of compute required Packages# yum Install Openstack-nova-api
