this time we first use a switch to connect 4 nodes intranet, then use a router to connect the extranet network card, and disable the router's DHCP service, and configure the WAN. After this network is connected, we modify the network configuration of each machine as shown in Figure 13.

Openstack-dashboard Development Environment Building and openstack Building
1. during the development process, it is generally necessary to run the dashboard component separately in your local linux system (Ubuntu or centos), which is preferred. If you are not used to it, you can use vmwareworkstation to install a virtual machine and switch over at any time.

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

Puppet has already joined openstack directly. Its official identity maintains the puppet openstack module, and the openstack
cannot be validated.
And then configure the OpenStack the most complex piece of network, in fact, according to the network topology I gave the default value can be installed, is not very convenient? But still to be long-winded:
Public IP is used for physical machine and external communication, floating IP is used to dynamically assign to OpenStack instance implementation and external communication.
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

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.

As a core tutorial for OpenStack, we have come to the final summary.
OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron. Please look at the following figure:

The instance of OpenStack is deployed through glance mirroring, so preparing mirroring is a must. This section describes how to make a Linux image, followed by a discussion of Windows mirroring. Download Clould Mirrors
The easiest way to do this is to use standard mirrors. Mainstream Linux distributions provide cloud mirrors that can be used directly in
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
