默認安裝好Fedora後，yum就可以使用了，但由於服務器在國外，速度奇慢無比，因此需要手動設置一下，可大大提高yum的速度
1，安裝 yum-fastestmirror 插件
yum install yum-fastestmirror -y
2，添加livna源，為了提高yum的下載速度，所以我們使用清華的源
先下載
ftp://ftp3.tsinghua.edu.cn/mirror/livna/livna-release-7.rpm雙擊安裝
編輯/etc/yum.repos.d/livna.repo
以root 編輯
gedit /etc/yum.repos.d/livna.repo
在baseurl= 下面添加清華的源
下面貼上我的配置
然後一行命令對整個系統升級
yum update -y
3，安裝圖形化的yum
yum install yumex
