YUM的配置：
只要把 yum的更新地址改成开源的就行了。
而限定yum更新地址的文件在/etc/yum.repos.d/里，先把它们改成备份文件，即在后面加.bak。
mv  /etc/yum.repos.d/rhel-debuginfo.repo  /etc/yum.repos.d/rhel-debuginfo.repo.bak
mv  /etc/yum.repos.d/rpmforge.repo.rpmnew  /etc/yum.repos.d/rpmforge.repo.rpmnew.bak

建立新的配置文件：
cd  /etc/yum.repos.d
touch  rhel-debuginfo.repo  mirrors-rpmforge  rpmforge.repo

编辑配置文件1：
vi rhel-debuginfo.repo
[base]
name=CentOS-5 - Base

# vi dag.repo

gpgcheck=1

编辑配置文件2：
vi  mirrors-rpmforge
http://apt.sw.be/redhat/el5/en/$ARCH/dag
http://archive.cs.uu.nl/mirror/dag.wieers/redhat/el5/en/$ARCH/dag
http://ftp2.lcpe.uni-sofia.bg/freshrpms/pub/dag/redhat/el5/en/$ARCH/dag

编辑配置文件3：
vi  rpmforge.repo
# Name: RPMforge RPM Repository for Red Hat Enterprise 5 - dag
# URL: http://rpmforge.net/
[rpmforge]
name = Red Hat Enterprise $releasever - RPMforge.net - dag
#baseurl = http://apt.sw.be/redhat/el5/en/$basearch/dag
mirrorlist = http://apt.sw.be/redhat/el5/en/mirrors-rpmforge
#mirrorlist = file:///etc/yum.repos.d/mirrors-rpmforge
enabled = 1
protect = 0
gpgkey = file:///etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag
gpgcheck = 1

如果速度慢的话可以通过增加yum的超时时间，这样就不会总是因为超时而退出。
vi  /etc/yum.conf
加上这么一句：timeout=120

还有一个包需要安装：rpmforge-release-0.3.6-1.el5.rf.i386.rpm
如果不安装的话有可能会出现以下错误：GPG key retrieval failed: [Errno 5] OSError: [Errno 2] 没有那个文件或目录: '/etc/pki/rpm-gpg/RPM-GPG-KEY-rpmforge-dag'

接下来就是输入KEY了。
rpm --import http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-5
或
rpm --import http://mirror.be10.com/centos/RPM-GPG-KEY-CentOS-5

加速yum
yum  install  yum-fastestmirror  yum-presto
指定或去掉软件源的mirror:
可以在baseurl中将比较慢的mirror去掉
你的yum镜像的速度测试记录文件：
/var/cache/yum/timedhosts.txt

yum Existing lock 错误的解决办法
如果系统启动的时候， yum 出现Existing lock /var/run/yum.pid: another copy is running as pid 3380. Aborting. 可以用下面的办法解决：
/etc/init.d/yum-updatesd  stop
也可以用以下方法：
rm  -f  /var/run/yum.pid
主要原因就是yum在自动更新只要关掉它就可以了
