安装基础包
首先安装提供基础配置文件和 GPG 密钥的 rpmfusion-*.rpm。
Fedora 用户
sudo yum install --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm或者如下直接用镜像中的 rpm 包：
sudo yum install --nogpgcheck https://(Loading...)/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://(Loading...)/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpmCentOS/RHEL 用户
发行版
sudo yum localinstall --nogpgcheck https://(Loading...)/free/el/rpmfusion-free-release-8.noarch.rpm https://(Loading...)/nonfree/el/rpmfusion-nonfree-release-8.noarch.rpm修改链接指向镜像站
安装成功后，使用以下命令修改 /etc/yum.repos.d/ 目录下以 rpmfusion 开头，以 .repo 结尾的文件：
sudo sed -e 's!^metalink=!#metalink=!g' \
-e 's!^mirrorlist=!#mirrorlist=!g' \
-e 's!^#baseurl=!baseurl=!g' \
-e 's!https\?://download1\.rpmfusion\.org/!https://(Loading...)/!g' \
-i.bak /etc/yum.repos.d/rpmfusion*.repo以 Fedora 下的 /etc/yum.repos.d/rpmfusion-free.repo 为例，替换后的文件类似如下：
[rpmfusion-free]
