Add a zone in CloudStack 4.4 Learning Summary)

 

1. Add a zone ):

 

The region is the largest organization unit in CloudStack deployment. Although multiple regions are allowed in a data center, a region usually corresponds to a data center. The benefit of grouping an infrastructure into a region is that it provides physical isolation and redundancy. For example, each region can have its own power supply and uplink network solutions, and each region can be geographically separated (although not necessarily far apart ).

 

① Create a zone ):

 

[Infrastructure] --> [view region] --> [add region]

650) this. width = 650; "src =" http://static.oschina.net/uploads/space/2014/1107/150824_CPSQ_727880.png "alt =" 1501__cpsq_727880.png "/>

② Select Add basic region:

 

[Basic] --> [Next]

③ Set the region:

 

[Enter the region name] --> [DNS] --> [select virtual machine management program] --> [Next]

Enter the region name, DNS, and virtual machine management program only]

④ Set the physical network:

⑤ Settings:

 

To configure a pod, you can simply give the IP address used by the CloudStack internal system, such as the IP address used by the system VM, the management IP address, and the ip address of the created virtual machine.

The Pod corresponds to a rack. Machines in the same pod are in the same subnet (network segment.

6. Set the guest network:

 

The IP address segment required for the created virtual machine.

7. Configure the cluster:

 

Name the kvm cluster.

Add the first host:

 

Enter the login user and password of the node host. We recommend that you use the root account.

Configure primary storage:

Configure secondary storage:

11. Prepare the start area:

12. Startup region:

13. View the infrastructure:

 

System VM. The value is 0 at the time of creation, and 2 is displayed after a period of time.

14. View the system VM:

 

The biggest problem during the adding process may be that the system VM cannot be created or started, and the log is always displayed in the creation of the system VM. In this case, make sure that the node has sufficient resources.

System VM, unlike the virtual machine on a common hypervisor host, it is a vm that comes with CloudStack to complete some tasks related to its own system. It has two types:

Second-level Storage VM (Secondary Storage VM): downloading and uploading templates and downloading images. When creating a virtual machine for the first time, you can copy templates from second-level Storage to level-1 Storage and automatically create snapshots.

Console Proxy VM: used to display the Console on the web interface.

It should be noted that the system virtual machine is a 32-bit Debian operating system, and the CloudStack administrator can log on through SSH. At the same time, you can view them in/var/lib/libvirt/images of the host.

 

15. View node status:

 

Check the mounted NFS directory on the node and the startup status of the system virtual machine as follows. The management program automatically mounts the file. You do not need to manually mount the file. However, make sure that the [/mnt] Directory is empty.
