noseor Easy_install noseor Python setup.py installLet's say you have successfully installed nose, then build a test folder, create a new test.py, and then enter the following:def Testfunc (): a=0 b=2 assert a==bThen execute the nosetests in the directory, with the following results:Why only input nosetests automatically executes the test.py in the directory and executes the TESTFUNC function inside, because nose automatically recognizes the test cases in the directory, any

The following command runs on the operating system Ubuntu 14.04.In open source software, the main use is KVM and Xen. Although OpenStack supports KVM and Xen, OpenStack support for KVM is significantly better than Xen, so the virtualization tools we choose here are KVM.Kernel-based VM KVM (kernel-based virtual machine) requires two conditions: hardware supports f

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

wants to know how to deploy a distributed, high-availability OpenStack, refer to the related articles on the network.So, I chose the CentOS and Redhat tools Packstack to deploy a single-node OpenStack. Currently Cloudfoundry only supports Folsom,grizilly, and Havana three versions of OpenStack.0. Hardware requirements

also growing, resulting in demands for multi-hypervisor management tools and technologies on cloud computing platforms. As an industry-leading open-source cloud computing management platform, openstack provides excellent support for hybrid hypervisor management. What is openstack? Openstack is both a community and an

control, and so on. Integrated into the project from the Essex version.Measurement (metering): Ceilometer. Like a funnel, it collects almost all the events that occur within the OpenStack, and then provides data support for billing and monitoring and other services. Integrated into the project from the Havana version.Deployment Choreography (Orchestration): Heat[2]. Provides an automated deployment of cloud infrastructure software running environment

Objective OpenStack is an open source IaaS (infrastructure and services) cloud computing platform that allows anyone to build and deliver cloud computing services on their own. OpenStack consists of a series of interrelated projects that provide various components of cloud infrastructure solutions, core projects (9): 1, calculation (Compute)-Nova; 2, Network and address management-neutron; 3, Object St

For OpenStack beginners, installation is often a big headache for getting started. Before the E version, to build a basic can use OpenStack environment that is quite troublesome, their own to install, their own source, according to the document to knock orders, and no reliable documents, the official document still have a lot of holes, and language problems are often used for a few days can not be loaded up

crowbar of Dell is an ISO. After installation, you can deploy openstack on the web interface. Chef is actually used. With Nagios monitoring integrated, the installation of OS is developed by Dell and is somewhat innovative. In the past, a major feature of Dell's crowbar was the remote configuration of raid and bios on the machine. This was from Dell, and I knew that I could do this. However, this feature also led to vendor binding, as well as how Del

dominates OpenStack. OpenStack users tend to use open source components, 93% of the OpenStack Cloud runs KVM (Kernel Virtual machine hypervisor), and the second manager is QEMU (16%). While VMware is committed to incorporating its own tools into the OpenStack ecosystem, onl

All along, for OpenStack beginners, installation is often the first big problem of getting started. Before the E version, to build a basic OpenStack environment that is quite troublesome, they have to install, their own source, according to the document to knock orders, and there is no reliable documents, the official documents still have a lot of pits, and language problems often with a few days of time ca

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

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.

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: This figure is truncated from https://www.openstack.org/software/project-navigator/, which is the official 6 Core Service defined by

installation, configuration, operation, and troubleshooting of these OpenStack services, you should consider the following few steps when using production architecture deployment. Identify and implement the necessary core and optional services to meet performance and redundancy requirements. Security is enhanced using methods such as firewalls, encryption, and service policies. Automate the deployment and management of your productio
