RPM Fusion provides software that the Fedora Project or Red Hat doesn't want to ship. That software is provided as precompiled RPMs for all current Fedora versions and Red Hat Enterprise Linux 5 and 6; you can use the RPM Fusion repositories with tools like yum and PackageKit.
We have two separate software repositories:
free for Open Source Software (as defined by the Fedora Licensing Guidelines) which the Fedora project cannot ship due to other reasons
nonfree for redistributable software that is not Open Source Software (as defined by the Fedora Licensing Guidelines); this includes software with publicly available source-code that has "no commercial use"-like restrictions
You need to enable EPEL on RHEL 5 & 6 or compatible distributions like CentOS before you enable RPM Fusion for EL.
For EL6 32 Bit: (32位和64位使用的rpm其实是一样的，noarch，两者皆可，下同)
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm'
For EL6 64 Bit:
su -c 'rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm'
To enable access to both the free and the nonfree repository use the following command:
## RHEL/CentOS 6 32 Bit OS ##
su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/el/updates/6/i386/rpmfusion-free-release-6-1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/6/i386/rpmfusion-nonfree-release-6-1.noarch.rpm'
## RHEL/CentOS 6 64 Bit OS ##
su -c 'yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/el/updates/6/x86_64/rpmfusion-free-release-6-1.noarch.rpm http://download1.rpmfusion.org/nonfree/el/updates/6/x86_64/rpmfusion-nonfree-release-6-1.noarch.rpm'
