Installation and uninstall of RPM commands for Linux RPM packages __linux

Under the Linux operating system, almost all software is installed, uninstalled and managed by RPM. The RPM is all called Redhat Package Manager, which is proposed by the Redhat company to manage software packages under Linux. When Linux is installed, almost all other modules are installed through RPM, except for a few core modules. RPM has five modes of operation: Installation, uninstall, upgrade, query, and authentication.
