Red Hat Package Management
RPM

What is a package?

A package is a group of software. A package is basically a compressed archive which contains the files
associated with a specific software, like compiled binaries and libraries, plus metadata and instructions
about where and how those files should be installed on the system, the external dependencies the software
needs to run correctly and more. RHEL and CentOS uses the rpm package format which was invented
by Red Hat itself:

Red hat Package Manager
 RPM is both an installation method as well as package format.
 RPM packages were originally created of Red Hat Linux, but now can be used on many Linux
distributions like CentOS, Fedora, SUSe, Mandrive, etc.
 Using RPM we can
 Install new applications
 Upgrade existing applications
 Remove installed applications
 Query Packages

RPM Pattern: -

Location of RPM: - In RHEL 5 the packages are available at “Server” directory at OS dump.
But in RHEL 4 the packages are available at “REDHAT/RPMS” location.
From internet also we can find the RPMS, in www.rpmfind.net, www.sourceforge.net,
www.phone.net and www.google.com/linux
 Method of Installation
 Standalone Method
