Rally IntroductionRally integrates deployment, API testing, stress testing capabilities (such as), but we typically deploy with Devstack, Tempest API testing, so Rally is often used to simulate stress testing in high-concurrency scenarios. Rally tests the OpenStack scale and performance by testing the corresponding time and request success rate of OpenStack in concurrent APIs.1. Deploy Rally$ git clone http

The recent deployment of OpenStack involves a number of concepts between the various services, briefly documenting some of them as memos.Services (Service)In OpenStack, a service has several endpoints through which the user accesses the service and uses the functionality provided by the service;Compute Services (Compute service)- NovaNetwork Services (Networking service)--neutronIdentity Service--keystoneIm

Video link: http://edu.51cto.com/index.php?do=lessonid=127539Introduction: Many OpenStack practitioners are complaining about the high cost of cloud platform deployment, maintenance difficult, small white users are complaining about the OpenStack threshold is too high, the entry is too difficult, some senior OpenStack architects are reluctant to share with you th

, so you can repeat each time. Correct use of the automatic configuration management tool not only simplifies the automatic deployment release of deployment and configuration changes, but also ensures that each component of the cloud system is in a specific State. These tools also make it possible to test and roll back changes, as they are fully repeatable. conveniently, a large body of work has been done by the openstack community in this space. pu

Openstack: a solution to slow network access on control nodes.Problem In a dual-node environment, the instance access network on the "control node + computing node" is normal, however, instances on computing nodes copy files from other machines very slowly, with only dozens of KSolution Through the query of some information on the Internet, this may be caused by MTU. Therefore, MTU is reconfigured for all instances on the computer, and the result spee

Openstack compute (NOVA) Function Analysis Openstack compute provides a cloud tool for an organization. Its functions include running Virtual Machine instances,Manage networks and control cloud access through users and projects. The most basic open-source project of openstack is named Nova. It provides software that can control the infrastructure

Use the Curl command in OpenStack to get token and access the underlying APIIn Oepnstack, access to the services provided (such as creating a virtual machine, etc.) requires first obtaining a certified token, which is a credential, obtained by sending a load authentication request to the OpenStack identity module, typically with a user name and password in the payload. When accessing the services provided a

Want to take a floodlight+openstack environment, floodlight Easy but OpenStack took more than 10 daysThe OpenStack configuration is difficult, so let's talk about my journey to OpenStack, and we have a little bit of a detour.1. Previously installed with the fuel tool. In my notebook to open a virtual machine as a node,

Download the official OpenStack document for installation (Icehouse Juno Kilo), according to the official documentation, download two RPM packages, for example, I want to build OpenStack Icehouse on centos6.5, need two installation packages, EPEL-RELEASE-6.8-NOARCH.RPM source package, in one is rdo-release--icehouse-4-src.rpm opened under window. Check the configuration profile inside, there are Foreman.rep

Steps for building OpenStack F Based on Ubuntu Server 12.04This article builds a dual-node architecture, which can be divided into computing (IP1) and control node (IP2) Note: Computing node components: 1. mysql 2. keystone 3.

For beginners, OpenStack manual deployment is cumbersome and takes more time to learn. But we can use deployment scripts to install OpenStack.Online there is a known as the most stupid OpenStack deployment tool called Devstack. I used to think it was quite a fool. The component is pulled straight down from GitHub, not only slow not to say, Even version compatibility may be problematic. It took 4 hours to in
