更换Fedora的yum升级源
更换Fedora 的yum升级源，Fedora均可以用
Fedora发行版一直没有采用Ubuntu中动态选择升级源的技术，让我们这些粉丝真的很郁闷；国内的开源镜像源也就sohu、163和上海交大那几个，速度吗还是要比国外的快点，我们只好自己动手来更换fedora的升级源啦；
第一步：下载fedora-sohu.repo和fedora-updates-sohu.repo，放入/etc/yum.repos.d/文件夹下，
第二步：运行yum makecache生成缓存；这样就可以使用了，OK。
以下是说明：
这是sohu的源，这两个文件原来是为fedora 7～13设计的，现在也已经适用14啦；赶快体验一下吧！
如果无法下载，就把以下内容分别保存为fedora-sohu.repo和fedora-updates-sohu.repo并放入/etc/yum.repos.d/文件夹下，然后运行yum makecache生成缓存；
