OpenStack is an excellent cloud operating system, and it is wise for developers, administrators, and operators to have the skills associated with them in their virtual toolkit. Efficient cloud requires an efficient database and can accept multiple databases. But what if you want IBM? DB2 for OpenStack, what should I do? OpenStack does not support DB2 by default.
API front-end servicesEach OpenStack component may contain several sub-services, which must have an API service that is responsible for receiving customer requests.In Nova, for example, Nova-api as a unique window to the Nova component, exposing the capabilities that Nova can provide to customers. When customers need to perform VM-related operations, they can and only send REST requests to NOVA-API. Customers here include end users, command lines, and

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile
Installing openstack through an external network may require a large amount of events to be downloaded from the RPM package, and may be unable to access the external network environment at some customer sites, for convenient and quick installation, you can build a yum source by yourself.
