RHEL5下使用centos源更新设置

[root@killgoogle ~]rpm -ivh ftp://ftp.cs.stanford.edu/pub/rpms/centos/5/i386/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
[root@killgoogle ~]# mv /etc/yum.repos.d/rhel-debuginfo.repo /etc/yum.repos.d/rhel-debuginfo.repo.bak
[root@killgoogle ~]# mv /etc/yum.repos.d/rpmforge.repo.rpmnew /etc/yum.repos.d/rpmforge.repo.rpmnew.bak

建立新的配置文件：
[root@killgoogle ~]# cd /etc/yum.repos.d
[root@killgoogle ~]# touch rhel-debuginfo.repo
[root@killgoogle ~]# touch mirrors-rpmforge
[root@killgoogle ~]# touch rpmforge.repo

往新的配置文件写东西：
[root@killgoogle ~]#vi rhel-debuginfo.repo
[base]
name=CentOS-5 - Base
#mirrorlist=
repo=os
#baseurl=
baseurl=
gpgcheck=1
gpgkey=

#released updates
[update]
name=CentOS-5 - Updates
#mirrorlist=
baseurl=
gpgcheck=1
gpgkey=

#packages used/produced in the build but not released
[addons]
name=CentOS-5 - Addons
#mirrorlist=

baseurl=
gpgcheck=1
gpgkey=

#additional packages that may be useful

gpgcheck=1
gpgkey=

#additional packages that extend functionality of existing packages
[centosplus]

#mirrorlist=
baseurl=
gpgcheck=1

gpgkey=

#contrib - packages by Centos Users
[contrib]
name=CentOS-5 - Contrib
#mirrorlist=
baseurl=
gpgcheck=1
enabled=0
gpgkey=

# vi dag.repo
[dag]
name=Dag RPM Repository for RHEL5
baseurl=
enabled=1
gpgcheck=1
gpgkey=

修改第二个配置文件：
[root@killgoogle ~]vi mirrors-rpmforge



#








修改第三个配置文件：
[root@killgoogle ~]# vi rpmforge.repo
# Name: RPMforge RPM Repository for Red Hat Enterprise 5 - dag
# URL:
[rpmforge]
name = Red Hat Enterprise $releasever - RPMforge.net - dag
#baseurl =
mirrorlist =
#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

[root@killgoogle ~] rpm --import
[root@killgoogle ~]yum install yum-fastestmirror yum-presto
