Installing RPMforge

RPMforge is a collaboration of Dag and other packagers. They provide over 5000 packages for CentOS, including wine, vlc, mplayer, xmms-mp3, and other popular media tools. It is not part of Red Hat or CentOS but is designed to work with those distributions. See also Using RPMforge and Repoforge.

Note: Because this repository is NOT part of CentOS, you should direct support questions to its maintainers at the Repoforge Users mailing list.

Packages are supplied in RPM format and in most cases are ready to use. The default RPMforge repository does not replace official CentOS base packages.

1. RPMforge for CentOS 6

The default RPMforge repository does not replace any CentOS base packages. In the past it used to, but those packages are now in a separate repository (rpmforge-extras) which is disabled by default.

You can find a complete listing of the RPMforge package packages at http://packages.sw.be/

Download the rpmforge-release package. Choose one of the two links below, selecting to match your host‘s architecture. If you are unsure of which one to use you can check your architecture with the command uname -i

• i686 http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.i686.rpm

• x86_64 http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm

The preferred rpmforge-release package to retrieve and to install in order to enable that repository is one of the two listed above.

Install DAG‘s GPG key

rpm --import http://apt.sw.be/RPM-GPG-KEY.dag.txt

If you get an error message like the following the key has already been imported:

error: http://apt.sw.be/RPM-GPG-KEY.dag.txt: key 1 import failed.

Verify the package you have downloaded

rpm -K rpmforge-release-0.5.3-1.el6.rf.*.rpm

Security warning: The rpmforge-release package imports GPG keys into your RPM database. As long as you have verified the md5sum of the key injection package, and trust Dag, et al., then it should be as safe as your trust of them extends.

Install the package

rpm -i rpmforge-release-0.5.3-1.el6.rf.*.rpm

This will add a yum repository config file and import the appropriate GPG keys.

Then try to install something like this

yum install htop
