OpenStack is in full swing, now the Liberty version has been released, the following step-by-step step-by-Step Introduction to this version of the stand-alone deployment. Of course, if you have multiple servers, you can also follow the tutorial for distributed deployments. This article assumes that the reader has a basic understanding of OpenStack architecture an

Original article: http://www.hengtianyun.com/download-show-id-79.html The resize (upgrade) function of openstack allows us to change the number of CPU cores, memory, and disk size of the Virtual Machine. Of course, the virtual machine can only be upgraded up and cannot be downgraded down. By analyzing the source code, we found that the resize process is actually a cold migration process, and the resize mult

Start speaking today about installing the components in OpenStack, then install it from Keystone, a secure authentication service, and, of course, there are some preparations to make before installing.First of all, what is the next keystone to do?In fact, in the early morning OpenStack is not keystone This component, some security authentication for example, user

This blog post has been quietly in the draft box for more than half a year. If it is not asked for some reason or the loss caused by ignoring it, I do not know when to complete it. I am grateful for the setbacks I 've experienced during this period. I hope you can give me more determination! This article attempts to describe in detail the complete process of creating a virtual machine in openstack, from the user's request to the successful running of

copying, you will forget the role of the command you just executed, therefore, I think it is wrong to copy and paste documents on the official website to improve my own level. Many friends think that the documents on the official website are too messy to read. In fact, the documents on the official website are not for Tom, it requires you to have a comprehensive understanding of openstack, so that you can understand what it is talking about. This is

coordination between the guest operating system and bare hardware, and some protected instructions must be captured by hypervisor (hypervisor). Full virtualization runs faster than hardware simulations, but is less performance than bare metal. Semi-virtualized (Para virtualization)Para-virtualization is another technology similar to full virtualization, which uses hypervisor to share access to the underlying hardware, but its guest operating system integrates virtualization-related code.

In the smooth installation of the deployment of Keystone, the original thought of Swift installation and commissioning will be like Keystone general, but the process is full of frustrations, in combination with some of the source code functions, finally successfully completed the installation of Swift, and experimented with uploading and downloading files and other functions, The following is an overview of Swift's installation process and a summary of the problems encountered, hoping to enlight

What is OpenStack? OpenStack provides open source software to build public and private clouds. OpenStack is a community, project, and open source software that helps enterprises run virtual computing or storage cloud. The OpenStackd open-source project is maintained by the community, including OpenStack computing (code

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

"TechTarget China original" Although the online installation tutorials and step-by-steps provided by OpenStack are a great help to administrators, there are still a lot of things that are not satisfactory. So in the process of installing OpenStack on Ubuntu, you can use the following documentation to compensate for the lack of official tutorials. The simplest way to learn how to use

This blog post mainly builds the keystone component in the openstack architecture, and then it will successively manage glance, Nova, neutron, Horizon, cinder, and virtual machines in openstack. Before deploying the experiment, you must first learn about openstack!What is openstack?

The previous section describes the architecture of Cinder, which discusses how Cinder components work together and how they are designed.How cinder-* Sub-services work together from the volume creation processFor Cinder learning, Volume creation is a very good scene, involving each cinder-* sub-service, the following is a flowchart. The customer (which can be an OpenStack end-user or other program) sends a request to the API (CINDER-API): "Create

But at this point, you still can't access the virtual machine via SSH, because the SSH default setting is to disable password authentication, so you need to do more work. #!/bin/shpasswd ubuntu This allows you to use SSH to login to the virtual machine without having to go through the console.
