In this way, when the program runs, a null pointer will be reported. Sometimes the business logic in the project may be complicated. If the test is not a crazy test, some logics will not be accessible, some s
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.
