RPM Package Manager RPM originally Red Hat Package Manager now a recursive acronym is a package management system. The name RPM refers to the following the. RPM was intended primarily for Linux distributions the file format is the baseline package format of the Linux Standard Base. Even though it was created for use in Red Hat Linux, RPM is now used in many Linux distributions. It has also been ported to some other operating systems, such as Novell Net. Ware as of version 6. SP3 and IBMs AIX as of version 4. An RPM package can contain an arbitrary set of files. The larger part of RPM files encountered are binary RPMs or BRPMs containing the compiled version of some software. There are also source RPMs or SRPMs files containing the source code used to produce a package. These have an appropriate tag in the file header that distinguishes them from normal BRPMs, causing them to be extracted to usrsrc on installation. SRPMs customarily carry the file extension. DOS FAT. HistoryeditRPM was originally written in 1. Erik Troan and Marc Ewing,1 based on pms, rpp, and pm experiences. Rik Faith and Doug Hoffman in May 1. Red Hat Software, its design and implementations influenced greatly by pms, a package management system by Faith and Kevin Martin in the fall of 1. Bogus Linux Distribution. Pristine Sources patches paradigm of pms, while adding features and eliminating arbitrary limitations present in the implementation. FeatureseditFor a system administrator performing software installation and maintenance, the use of package management rather than manual building has advantages such as simplicity, consistency and the ability for these processes to be automated and non interactive. Features of RPM include RPM packages can be cryptographically verified with GPG and MD5. Original source archives e. SRPMs, making verification easier. Patch. RPMs and Delta. RPMs, the RPM equivalent of a patch file, can incrementally update RPM installed software. Automatic build time dependency evaluation. Local operationseditPackages may come from within a particular distribution for example Red Hat Enterprise Linux or be built for it by other parties for example RPM Fusion for Fedora. Circular dependencies among mutually dependent RPMs so called dependency hell can be problematic 9 in such cases a single installation command needs to specify all the relevant packages. RepositorieseditRPMs are often collected centrally in one or more repositories on the internet. A site often has its own RPM repositories which may either act as local mirrors of such internet repositories or be locally maintained collections of useful RPMs. Front endseditSeveral front ends to RPM ease the process of obtaining and installing RPMs from repositories and help in resolving their dependencies. These include yum used in Fedora, Cent. OS 5, Red Hat Enterprise Linux 5 and above, Scientific Linux, Yellow Dog Linux and Oracle Linux. DNF, introduced in Fedora 1. Red Hat Enterprise Linux, Cent. OS 3 and 4, and Oracle Linux. Zypper used in Mee. Go,1. 0open. SUSE and SUSE Linux Enterpriseurpmi used in Mandriva Linux, ROSA Linux and Mageiaapt rpm, a port of Debians Advanced Packaging Tool APT used in Ark Linux,1. PCLinux. OS and ALT Linux. Smart Package Manager, used in Unity Linux, available for many distributions including Fedora. Red Hat Enterprise Linux. Local RPM installation databaseeditWorking behind the scenes of the package manager is the RPM database, stored in varlibrpm. It uses Berkeley DB as its back end. It consists of a single database Packages containing all of the meta information of the installed rpms. Multiple databases are created for indexing purposes, replicating data to speed up queries. The database is used to keep track of all files that are changed and created when a user using RPM installs a package, thus enabling the user via RPM to reverse the changes and remove the package later. If the database gets corrupted which is possible if the RPM client is killed, the index databases can be recreated with the rpm rebuilddb command. DescriptioneditWhilst the RPM format is the same across different Linux distributions, the detailed conventions and guidelines may vary across them. How To Install Software In Fedora 15' title='How To Install Software In Fedora 15' />The name of Fedora derives from Fedora Linux, a volunteer project that provided extra software for the Red Hat Linux distribution, and from the characteristic fedora. Step 1 Configure OBS Repository. Package filename and labeleditAn RPM is delivered in a single file, normally in the format lt name lt version lt release. Source code may also be distributed in RPM packages in which case the lt architecture part is specified as src as in, libgnomeuimm 2. RPMs with the noarch. These include graphics and text for another program to use, and programs written in interpreted programming languages such as Python programs and shell scripts. The RPM contents also include a package label, which contains the following pieces of information software namesoftware version the version taken from original upstream source of the softwarepackage release the number of times the package has been rebuilt using the same version of the software. This field is also often used for indicating the specific distribution the package is intended for by appending strings like mdv formerly, mdk Mandriva Linux, mga Mageia, fc. Fedora Core 4, rhl. Red Hat Linux 9, suse. SUSE Linux 1. 0. 0 etc. The package label fields do not need to match the filename. Library packagingeditLibraries are distributed in two separate packages for each version. One contains the precompiled code for use at run time, while the second one contains the related development files such as headers, etc. Those packages have devel appended to their name field. The system administrator should ensure that the versions of the binary and development packages match. The format is binary and consists of four sections 5The lead, which identifies the file as an RPM file and contains some obsolete headers. The signature, which can be used to ensure integrity andor authenticity. The header, which contains metadata including package name, version, architecture, file list, etc. A file archive the payload, which usually is in cpio format, compressed with g The rpm. RPM package. 1. More recent versions of RPM can also use b RPM 5. SPEC fileeditThe Recipe for creating an RPM package is a spec file. Spec files end in the. RPM revision number, steps to build, install, and clean a package, and a changelog. Multiple packages can be built from a single RPM spec file, if desired. RPM packages are created from RPM spec files using the rpmbuild tool. Spec files are usually distributed within SRPM files, which contain the spec file packaged along with the source code. A typical RPM is pre compiled software ready for direct installation. The corresponding source code can also be distributed. This is done in an SRPM, which also includes the SPEC file describing the software and how it is built. The SRPM also allows the user to compile, and perhaps modify, the code itself. A software package may contain only scripts that are architecture independent. In such a case only an SRPM may be available this is still an installable RPM. As of June 2. 01.
