RHEL7 Management of software packages

There are two main types of package management, RPM and Yum

Two kinds of package management are useful, the main difference is: Yum is simple to use but requires networking, Yum will go to the online Yum package to get the required packages. And the need of the RPM operation precision is relatively thin, we need to do more things.

RPM Package Management

Abbreviation: Redhat Package Manager

Mounting discs

Installing the RPM software

-I--install installation package

-V--verbose provides more detailed information output

-H--hash package is installed with hash marks listed
