Rhel 5 升级为centos 5 并配置 yum源

我的电脑平台是dell的d620，安装了rehhat5 client 和windows xp双系统。但是感觉rhel 5 使用本地源更新设置比较繁琐，而且不能更新到最新的包。在网上搜到了一篇相关的帖子，便按照指导安装并成功。记录下安装过程。以便备用。1.配置yum先把RHEL5自带的yum包删除，rpm -qa | grep yum，出来4个包，全部rpm -e 掉，还有一个RedHat-release，这个要—nodeps。然后从http://CentOS.ermly.com/centos/5.1/os/下载CentOS的4个与yum有关的包及centos-release-5-0.0安装。安装后的包如下yum-metadata-parser-1.0-8.fc6yum-3.0.5-1.el5.centos.5yum-updatesd-3.0.5-1.el5.centos.5修改yum的配置文件，vi /etc/yum.repos.d/CentOS-Base.repo# CentOS-Base.repo## This file uses a new mirrorlist system developed by Lance Davis for CentOS.# The mirror system uses the connecting IP address of the client and the# update status of each mirror to pick mirrors that are updated to and# geographically close to the client. You should use this for CentOS updates# unless you are manually picking other mirrors.## If the mirrorlist= does not work for you, as a fall back you can try the# remarked out baseurl= line instead.##[base]name=CentOS-5.1 - Basebaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/os/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5#released updates[updates]name=CentOS-5.1 - Updatesbaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/updates/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5#packages used/produced in the build but not released[addons]name=CentOS-5.1 - Addonsbaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/addons/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5#additional packages that may be useful[extras]name=CentOS-5.1 - Extrasbaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/extras/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5#additional packages that extend functionality of existing packages[centosplus]name=CentOS-5.1 – Plusbaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/centosplus/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1enabled=0gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5#contrib - packages by Centos Users[contrib]name=CentOS-5.1 - Contribbaseurl=http://mirror.tini4u.net/centos/5.1/os/$basearch/http://centos.ustc.edu.cn/centos/5.1/os/$basearch/http://ftp.daum.net/centos/5.1/os/$basearch/http://mirror.secuidc.com/centos/5.1/os/$basearch/http://centos.ermly.com/centos/5.1/contrib/$basearch/http://ftp.hostrino.com/pub/centos/5.1/os/$basearch/gpgcheck=1enabled=0gpgkey=http://centos.ermly.com/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5为了保证源的可用性，我添加了多个国内的centos源。导入rpm包的GPG密钥rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY*3. Update在终端下面执行yum -y update。遇到网速不好，重试几次，可以完全下载，共有538M之多。此时提示与redhat-logos冲突，继续rpm -e -nodeps redhat-logos，再次yum -y update，这时Updating, CleanUp, Complete！4.修复gdm登录界面重启后已经可以看到RHEL5改头换面成CentOS了，但是到gdm登录界面时提示出错，意为找不到gdm的相关主题。没关系，可以登录，只不过界面难看一点。进入Gnome桌面后，登录http://art.gnome.org下载一个自己喜欢的gdm logo theme. 在终端输入gdmsetup，把刚才下载的tar.gz拖到对话框中安装，再把默认的Redhat删除就OKay了！5.加快你的yum的速度.使用yum的扩展插件yum-fastestmirror，个人认为这个插件非常有效，速度真的是明显提高， #yum -y install yum-fastestmirror注意，在Centos 4上,名字叫yum-plugin-fastestmirror6.扩展你的rpm包好多包官方没有,怎么搞定他.要我自己编译吗？好了，你安装这个包,这个是redhat5的哦。你可以自己到http://dag.wieers.com/rpm/FAQ.php#B这来找rpm -Uhv http://apt.sw.be/packages/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.i386.rpm技巧3:rpm查找.centos5下用yum安装MPlayer播放器Ubuntu下最快电驴mldonkey 设置全过程图解相关资讯 CentOS RHEL 5 yum Centos 5
