经过艰苦的奋斗，终于搞定了fedora系统从安装到3D特效(本人安装的是fedora
11)，为了方便后来的linuxer，特留下本人的全过程以供参考。以下步骤有的来自于google搜索，有部分来自于嘉佑中文博客
（http://www.my-guides.net/en/content/view/164/26/），并感谢各方前辈的笔迹。
1.添加rpm fusion源
rpm -ivh
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm
2.导入rpm fusion仓库的密钥
rpm --import http://ATrpms.net/RPM-GPG-KEY.atrpms
3.修改密钥文件
gedit /etc/yum.conf
在打开的文件尾部添加下面几行：
[atrpms]
name=Fedora Core $releasever - $basearch - ATrpms
baseurl=http://dl.atrpms.net/f$releasever-$basearch/atrpms/stable
gpgkey=http://ATrpms.net/RPM-GPG-KEY.atrpms
gpgcheck=1
4.添加adobe软件仓并导入密钥
rpm -ivh http://linuxdownload.adobe.com/linux/i386/adobe-release-i386-1.0-1.noarch.rpm
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
5.添加上海交大的yum 源
vim /etc/yum.repos.d/sjtu.repo #不喜欢用vim 的人请用gedit
在打开的文件中添加如下行：
[fedora]
name=Fedora $releasever - $basearch
failovermethod=priority
baseurl=ftp://openware.byr.edu.cn/pub/mirror/fedora/linux/releases/$releasever/Everything/$basearch/os/
http://ftp.sjtu.edu.cn/fedora/linux/releases/$releasever/Everything/$basearch/os/
ftp://ftp.sjtu.edu.cn/fedora/linux/releases/$releasever/Everything/$basearch/os/
ftp://ftp.cuhk.edu.hk/pub/Linux/fedora/releases/$releasever/Everything/$basearch/os/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch
[updates]
name=Fedora $releasever - $basearch - Updates
failovermethod=priority
baseurl=ftp://openware.byr.edu.cn/pub/mirror/fedora/linux/updates/$releasever/$basearch/
http://ftp.sjtu.edu.cn/fedora/linux/updates/$releasever/$basearch/
ftp://ftp.cuhk.edu.hk/pub/Linux/fedora/updates/$releasever/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-fedora-$basearch
