D620本本RHEL5升级至CentOS5+Beryl

公司新配的本本Dell D620，120G的空间，装了Vista Ultimate。左思右想再装Linux，正好有上次参加westos拿到的RHEL5，就装了。不过仅仅是RHEL5，玩起来不爽，决定update to CentOS 5

1.寻找yum server
综合比较了几个server，就觉得还不错，至于微睦主机的yum server,速度不错，但总是出现403错误，就放弃了。

2.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，另外还有一个redhat-release，这个要--nodeps。然后从mirror.be10.com下载CentOS的4个与yum有关的包及centos-release-5-0.0安装。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-5.0 - Base
baseurl=
gpgcheck=1
gpgkey=

#released updates
[updates]
name=CentOS-5.0 - Updates
baseurl=
gpgcheck=1
gpgkey=

#packages used/produced in the build but not released
[addons]
name=CentOS-5.0 - Addons
baseurl=
gpgcheck=1
gpgkey=

#additional packages that may be useful
[extras]
name=CentOS-5.0 - Extras
baseurl=
gpgcheck=1
gpgkey=

#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-5.0 - Plus
baseurl=
gpgcheck=1
enabled=0
gpgkey=

#contrib - packages by Centos Users
[contrib]
name=CentOS-5.0 - Contrib
baseurl=
gpgcheck=1
enabled=0
gpgkey=

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238M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.安装beryl
从howtoforge.com找了一篇Installing Beryl On A CentOS5.0 Desktop，按照步骤很好做
首先是要安装好显卡驱动，我这款D620用的是nVidia Corporation Quadro NVS 110M / GeForce Go 7300，直接down一个NVIDIA最新的9639安装。
接下来配置CentOS Beryl安装源server
cd /etc/yum.repos.d/
wget
然后vi kbsingh-CentOS-Extras.repo，把里面的enable=0全部改为enable=1
导入RPM-GPG-KEY: rpm --import
好了，最后一步：yum -y install beryl
完成后就可以使用Applications -> System Tools -> Beryl Manager
Enjoy!
