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

Mirantis, one of the benchmark companies in the OpenStack field, released the latest MOS 8.0 version in early March 2016. This paper tries to make some inductive analysis based on the public data.1. Version Overview 1.1 overview Community version: Liberty, the default integrated components include ceilometer,Cinder,Glance,Heat,Horizon, Ironic (first support),Keystone,Murano (an application catalog, first-time support),Neutron (using Open vSwitch

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

What is C ++/CLI? C ++, of course, refers to Bjarne. Stroustrup, a C ++ language invented in BELL Labs, implements a static object model with optimized speed and size during runtime. However, it does not support dynamic modification of programs except heap allocation, It allows infinite access to the underlying device, but it is almost impossible to operate the activity type while the program is running, nor to operate the underlying structure assoc

For The first method is to use php-f/path/to/yourfile. php. Call the php cli interpreter and pass parameters to the script. In this method, you must first set the path of the php interpreter. Before Running CLI on Windows platform, you must set a command similar to path c: php, which also loses the meaning of the first line of the CLI script, therefore, this meth

Tags: Spark SQL hive CLIBackgroundThis article mainly introduces the current implementation of the CLI in Spark SQL, the code will certainly have a lot of changes, so I am concerned about the core of the logic. The main comparison is the implementation of the Hive CLI, comparing where the spark SQL was modified and where it is consistent with the hive CLI. You ca

First, the introduction C + + programmers react differently when Microsoft introduced Vs.net7 to implement extensible managed C + +. Although most programmers are relieved to be able to continue using C + +, almost everyone suffers from the arcane syntax provided by managed C + +. Microsoft clearly sensed from feedback that managed C + + was not so successful. October 6, 2003, ECMA (European Computer Manufacturers Association) announced the formation of a group of experts responsible for the i

a few days ago the customer's system to do upgrade, need to use Azure CLI, the new kid over there is not connected to my tutorial for an afternoon. After he told me, I rushed to help him find out what went wrong, always put the error analysis. I've tried it myself a couple of times and I can even get it right. At the end of the day, when I found out where the problem was, I was a small-faced animal. Well, the most reliable is always self. Write an art
