Cloud computing is currently a hot spot, in line with the idea of wage-oriented programming, began to learn cloud computing. There should be a burst of cloud computing growth in the coming years. Start with the OpenStack. a preface 8.1 now has three machines in his hand, a pad with a desk and a pen. Start thinking about using the three machines to do the experiment. But looking at the home page of the Install Guide configuration requirements and some

Reference: Official configuration document (http://docs.openstack.org/mitaka/install-guide-rdo/overview.html) Preface What OpenStack is. Official explanation: OpenStack is a cloud operating system this controls large pools of compute, storage, and networking resources Throug Hout a datacenter, all managed through a dashboard this gives administrators control while empowering their users to provi Sion resour

This build uses the multi-node installation, namely controller control node and compute compute Node Network node, eth0 for external network, ETH1 for internal management network.This address can be changed in accordance with the actual situation.Before deploying the platform, to make it easier for everyone, let's change the apt source, because if you use the source directly online, you also need to point to the version of OpenStack package, otherwise

Test classification in OpenStack Test categories in OpenStack can be divided into the following types:1) unit test (small test/unit tests) Unit tests are stored in the code library of each component. For example, unit tests of nova are stored in the nova/tests directory. Unit Tests are mainly aimed at testing the source code and testing the code at the function level. Need data or a simulated environmen

OpenStack is a cloud operating system that controls a large pool of computing, storage, and network resources in the entire data center. All resources are managed through a dashboard, which gives administrators control and allows users to prepare resources through the Web interface. OpenStack is a cloud operating system that controls a large pool of computing, storage, and network resources in the entire da

OpenStack, the installation threshold is relatively high, and quite cumbersome, many of the installation documentation authors save a lot of installation steps. This has brought a lot of trouble to beginners, and perhaps the author can easily save a step, will be created after the installation failure. And beginners are not very aware of OpenStack, errors can not be cleared, so many people are halfway to ab

Openstack-rocky version of ErrorError 1:Package download failure, after determining the system source is not a problem, found that Ping does not pass Baidu. Finally, a DNS resolution was added, stating that no DNS was added (/etc/resolv.conf).Error 2:As the Admin user, an error occurred while requesting the authentication token, should be a port error, when configured, using 5000, the following command in the test using 35357, so wrong.[[email protect

Installing OpenStack is a complex matter, especially if a component, a component, a single coding deployment, is estimated to be too time consuming, and the probability of error is high, it is very efficient and reliable to use tools to push deployment. Mirantis is a company that specializes in OpenStack services, has a high contribution to OpenStack, is now prof

Chinese garbled characters in OpenStack Databases The SQL connection of openstack must be configured with UTF-8 to avoid Chinese garbled characters. SQL _connection = mysql: // nova: xxx @ qa-mysql1: 3306/nova? Charset = 'utf-8' However, if UTF-8 is not set before, the database cannot be cleared at will. to update a field in the openstack database, you cannot dir

OpenStack has become the first choice for many cloud computing vendors to build a private cloud. Many academic institutions also use OpenStack to build a small-scale test environment for students' experiments. Here we will share the process of using OpenStack Virtual Machine to build the Hadoop2.2.0 environment. 1. Prepare the VM Environment

I have recently read about Openstack and have been trying to install it. However, I have referenced a lot of information, which is not satisfactory. Since CentOS has been used for Linux, most Openstack installation is required on Ubuntu. I don't know why. I don't like Ubuntu. Maybe I think it's too fancy, and I always want to update something.

BKJIA exclusive Article] OpenStack is a set of platform software used to manage virtual machines. Instead of a single software, it integrates many components for collaboration. Simply put, for example, there are ten servers. In the case of VMware, we install esx or esxi on each server, and then install a vcenter, in the vcenter management interface, you can add the esx of ten servers to the vcenter by adding domain names or ip addresses. Similarly, Re

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 multi-transmits a flavor parameter. The following
