What Is The RPM?

Hello,

Do you know what is the RPM?

RPM is the RPM Package Manager. It is an open packaging system available for anyone to use. It allows users to take source code for new software and package it into source and binary form such that binaries can be easily installed and tracked and source can be rebuilt easily. It also maintains a database of all packages and their files that can be used for verifying packages and querying for information about files and/or packages.

Red Hat, Inc. encourages other distribution vendors to take the time to look at RPM and use it for their own distributions. RPM is quite flexible and easy to use, though it provides the base for a very extensive system. It is also completely open and available, though we would appreciate bug reports and fixes. Permission is granted to use and distribute RPM royalty free under the GPL.

RPM is an open packaging system that is available for anyone to use. It works on all Linux as well as currently on various other UNIX flavours: IRIX, Solaris, SunOS, AIX, HP/UX, AmigaOS, and FreeBSD.

Installing Packages

RPM packages typically have file names rpm -i prashant-1.1-1.i386.rpm which includes :-

package name prashant

version 1.1

release 1

architecture i386

How to install RPM?

rpm -ivh prashant-1.1-1.i386.rpm

rpmsign

RPMSIGN(8)						      System Manager's Manual							RPMSIGN(8)

NAME

       rpmsign - RPM Package Signing

SYNOPSIS

       rpm --addsign|--resign PACKAGE_FILE ...

       rpm --delsign PACKAGE_FILE ...

DESCRIPTION

       Both  of  the --addsign and --resign options generate and insert new signatures for each package PACKAGE_FILE given, replacing any existing
       signatures. There are two options for historical reasons, there is no difference in behavior currently.

       rpm --delsign PACKAGE_FILE ...

       Delete all signatures from each package PACKAGE_FILE given.

   USING GPG TO SIGN PACKAGES
       In order to sign packages using GPG, rpm must be configured to run GPG and be able to find  a  key  ring  with  the  appropriate  keys.	By
       default,  rpm  uses  the  same conventions as GPG to find key rings, namely the $GNUPGHOME environment variable.  If your key rings are not
       located where GPG expects them to be, you will need to configure the macro %_gpg_path to be the location of the GPG key rings to  use.	If
       you want to be able to sign packages you create yourself, you also need to create your own public and secret key pair (see the GPG manual).
       You will also need to configure the rpm macros

       %_gpg_name
	      The name of the "user" whose key you wish to use to sign your packages.

       For example, to be able to use GPG to sign packages as the user "John Doe <jdoe@foo.com>" from the key rings located in /etc/rpm/.gpg using
       the executable /usr/bin/gpg you would include

       %_gpg_path /etc/rpm/.gpg
       %_gpg_name John Doe <jdoe@foo.com>
       %__gpg /usr/bin/gpg

       in a macro configuration file. Use /etc/rpm/macros for per-system configuration and ~/.rpmmacros for per-user configuration. Typically it's
       sufficient to set just %_gpg_name.

       rpmsign --help - as rpm supports customizing the options via popt aliases it's impossible to guarantee that what's described in the  manual
       matches what's available.
