This article is about how to add a regional zone in CloudStack 4. 4. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

CloudStack 4.4.Adding area (zone) 1, adding area (zone):

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

①, create zone (zone):

[infrastructure]-- > [View area]-- > [add region]

②, choose to add basic regions:

[basic]-- > [Next]

③, setting region:

[enter zone name]-- > [DNS]-- > [Select hypervisor]-- > [Next]

Only fill in: [region name], [DNS], [Hypervisor]

④, set up the physical network:

Just go straight to the next step.

⑤, settings to provide points:

Configuring pod can simply be understood as the IP used by the internal system of CloudStack, such as the IP used by the system VM, the management IP, and the virtual machine ip created.

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

⑥, set up the guest network:

The IP segment to be used by the virtual machine that is created.

⑦, configure cluster:

Name the cluster of kvm.

⑧, add the first host:

Fill in the login user and password of the node host, and the root account is recommended.

⑨, set up primary storage:

⑩, setting up secondary storage:

11. Prepare the launch area:

12. Startup area:

13. View the infrastructure:

The system VM, which was 0 when it was first created, can be seen as 2 after a while.

14. View the system VM:

The biggest problem in the adding process may be that the system VM cannot be created and started, and the log is always displayed in the creation of the system VM, so it is necessary to ensure that the node has sufficient resources.

The system VM, which is different from the virtual machine on the ordinary hypervisor host, is the vm that the CloudStack comes with to complete some tasks related to its own system. There are two kinds of it:

Secondary storage virtual machine (Secondary Storage VM): download upload template, download image, copy template from secondary storage to primary storage and automatically create snapshots when creating a virtual machine for the first time.

Console proxy virtual machine (Console Proxy VM): used to display the console on the web interface.

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

15. View node status:

Check the mounted NFS directory on the node and the startup of the system virtual machine as follows. The hypervisor mounts automatically. There is no need for manual unmount intervention, but make sure that the [/ mnt] directory is empty.
