I. Summary of the OpenStack
OpenStack is both a community, a project and an Open-source software that provides an operational platform or toolset for deploying the cloud.

In the past ten years, RHEL has made RedHat the dominant position in the enterprise-level Linux market. Ten years later, RedHat hopes to build an IaaS solution on OpenStack to realize the company's leapfrog development. RedHat is now focusing on cloud computing and plans to use it as the main driving force to support its business development in the next decade. Only this time, the most prominent focus is that Redhat has successfully invested money in

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.

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.

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 provides a wide range of network configuration environments. This article describes how to design a cloud system to consider and design network requirements.
If this is the first time you deploy a cloud system in your organization, please contact your network O M team after reading this section to learn about the current network conditions. The network used by the cloud system is different from the network deployment method used by the comm
