RPM briefly describes the abbreviation of REDHAT PACKAGE Manager, which is a package installation and manager developed by Redhat, similar to Uninstaller on the Windows platform. Using rpm, users can install and manage applications and system tools on Linux themselves. RPM allows users to install packages directly in a binary, and can be queried by the user has installed the relevant library files; when the program is deleted with RPM, it will smartly ask the user to delete the relevant program. If you use rpm to upgrade the software, RPM will keep the original profile so that users do not need to reconfigure new software. RPM retains a database that contains all the packages of all packages. With this database, users can check in packages. Although RPM is designed for Linux, it has been removed from other UNIX systems such as Sunos, Solaris, AIX, IRIX. RPM follows the GPL copyright protocol, and users can freely use and propagate RPM under conditions that meet the GPL protocol.
