yum是fedora中十分方便的软件包管理工具，但是其默认的源全是国外的站点上的，极大地影响了其下载资源的速度；因此应将其改为国内的镜像，清华大学的镜像站就是教育网内比较完善的镜像站点；建议教育网用户将yum源改为清华大学的镜像，极变态地提高下载速度。
具体操作如下（终端）：
1.获得root权限：
su
2.将/etc/yum.repo.d改名；
mv/etc/yum.repo.d/etc/yum.repo.d~
若要还原该文件夹则输入：
mv/etc/yum.repo.d~/etc/yum.repo.d
3.编辑/etc/yum.conf文件：
gedit/etc/yum.conf
将其改为:
class=codetop>CODE:class=codemain>[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=0
plugins=1
metadata_expire=1800

若要还原则输入：
gedit/etc/yum.conf
将其改为：
class=codetop>CODE:class=codemain>[main]
cachedir=/var/cache/yum
keepcache=0
debuglevel=2
logfile=/var/log/yum.log
pkgpolicy=newest
distroverpkg=redhat-release
tolerant=1
exactarch=1
obsoletes=1
gpgcheck=1
plugins=1
metadata_expire=1800 |
这样就能使用清华大学的源了。
测试一下：
yumcheck-update
速度怎样！
