ArticleDirectory About openstack Today is Yasushi Hara's last class in this course. We strongly recommend openstack for a look. So, Google. ---------------- OpenstackOfficial Website address You can see an obvious figure on the homepage of the official website, showing the structure of openstack,

specific analysis. Take a look at swift, as I said earlier, this technology is used by internet companies, but traditional companies are currently limited, and if you work in a traditional business, taking the time to learn Swift is certainly not a worthwhile investment. Of course, if you have a clear idea that your company will store objects, that's another story. Another module is Ceilometer, which belongs to the

The network topology structure of this OpenStack environment is shown in Figure 2. Figure 2: Network topology structure diagram Four Installing the deployment process (1) Install fuel Master Install fuel Master is to use our previously carved USB disk to install, the installation process does not have much to interfere with the place, that is, the normal installation of the system steps, after loading as shown in Figure 3.

next step is to install the OpenStack environment.Installing the OpenStack EnvironmentFirst create an OpenStack environment on the fuel web with the name "demo", which can be created in multiple, visible fuel can manage multiple openstack environments at the same time. There are three types of OS selected here, the de

If multiple memcache servers are used, add IP addresses as follows.

This tutorial is based on the Ubuntu12.04 edition, and it will help readers build a openstack minimized installation. I am the top of the Wuyue, translation more use of transliteration method, so the individual words and the original discrepancy, please understand. I am not a major in English, I think the most important thing is to understand the technology, and not the four level and grind in the boring English-Chinese translation, so my goal is loya

the OS selected here, the default selection CentOS, of course, you can also choose Ubuntu and Rhle, but Rhle need to upload a mirror manually or provide Red Hat official website username and password, fuel for you automatically download, but the time is longer, not recommended. Here you choose to deploy the OpenStack multi node non-ha mode. Since we are running the virtual machine again in the virtual ma

The development of openstack is fierce, and many friends agree that in 2013, the openstack deployment problem will be well solved, making the installation and configuration easier to use. Many companies have invested effort in doing this. Sina also plans to make an ISO for openstack and integrate OS. When you decide to do this, first understand the current situat

first, the basic knowledge of OpenStackOpenStack is a free software and open source project that was developed and initiated by NASA and Rackspace to Apache2.0 licenses (compatible with GPLv3 and DFSG).OpenStack is an open source cloud computing management Platform project, composed of several major components to accomplish specific tasks. OpenStack supports almost all types of cloud environments, and the p

Openstack official website content: http://docs.openstack.org/grizzly/openstack-object-storage/admin/content/ Because I only focus on the part of openstack Object Storage, I did not write anything related to other modules (or I am relatively lazy). I may add it if necessary in the future. The translation level is limited. If a netizen finds an error during re

This is the 1th chapter in the OpenStack implementation experience sharing series.The instance of OpenStack is deployed through a Glance mirror, so preparing the mirror is a must-do job. This section describes how to make a Linux image, and also discusses Windows mirroring later.Download Clould imageThe simplest approach is to use a standard image. The mainstream Linux distribution provides a cloud image th

OpenStack Object Storage Service (SWIFT) configuration: I added two hard drives (SDB,SDC) to the compute node for storage, and the compute node in my build is the storage node, because the computer can't pull more virtual ...

The following content is from: http://blog.csdn.net/gqtcgq/article/details/49620279 Stevedore is an open source module for implementing dynamic load code. It is a public module that is used to load plug-ins in OpenStack. Can be installed independently of OpenStack: https://pypi.Python.org/pypi/stevedore/ Stevedore uses Setuptools's entry points to define and load Plug-ins. Entry point refers to objects d

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile

By default, the Keystone service still listens on ports35357. Therefore, this guide disables the Keystone Service.This means that the httpd and
