返回信息流我对rhel比较熟悉，所以一直在rhel,fedora,centos里徘徊，大概是审美问题，一直觉得fedora不好看（喜欢沉稳类型），而且经常出问题
私下估计可能是本本的问题，还是rhel稳定，但是不能yum，曾经尝试多次从rhel5用centos5 yum，但是老出错，鉴于本人水平有限就不深究了，直接换cent0s5.2了，已经完全取代windows很久了，因为自己非常低级玩家，所以只要支持mp3和rm播放，俺就满足了，主要还是用gcc了，这里给的都是网摘，免得大家走弯路了，我走了很久才搞定了，大家要是高手别嘲笑俺，给俺这类型的菜鸟行方便么，不说废话了
1.使用学校的代理(是为了到rpmforge下常用软件准备的）
要从外网yum，没代理完全是废的
在/etc/profile.d/下面新建两个文件
文件proxy.csh内容如下：
export FTP_PROXY=http://usr:password@proxy.bupt.edu.cn:8080
export HTTP_PROXY=http://usr:password@proxy.bupt.edu.cn:8080
export http_proxy=http://usr:password@proxy.bupt.edu.cn:8080
export ftp_proxy=http://usr:password@proxy.bupt.edu.cn:8080
export no_proxy=ftp://openware.byr.edu.cn
文件proxy.sh内容如下:
export FTP_PROXY=http://usr:password@proxy.bupt.edu.cn:8080
export HTTP_PROXY=http://usr:password@proxy.bupt.edu.cn:8080
export http_proxy=http://usr:password@proxy.bupt.edu.cn:8080
export ftp_proxy=http://usr:password@proxy.bupt.edu.cn:8080
export no_proxy=ftp://openware.byr.edu.cn
2.中科大的centos5源
地址：/etc/yum.repos.d/，换掉即可
附件(1KB) CentOS-Base.repo
3.
yum -y update
yum install yum-fastestmirror //加速
这样yum就配置好了
4.现在该mplayer

这个是官方的[url]http://wiki.centos.org/Repositories/RPMForge[/url]
一、你可能要安装一个插件，特好用，yum速度一流，yum install yum-fastestmirror（我这边可以达到800K＋／S）
二、yum install yum-priorities
三、经过二后，你可以打开/etc/yum/pluginconf.d/priorities.conf 编辑成如下样子：
[main]
enabled=1
四、编辑 /etc/yum.repos.d/ ；改成如下形式：
[base]
name=CentOS-5 - Base
repo=os
baseurl=http://centos.ustc.edu.cn/centos/5.1/os/$basearch/
gpgcheck=1
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
[update]
name=CentOS-5 - Updates
baseurl=http://centos.ustc.edu.cn/centos/5.1/updates/$basearch/
gpgcheck=1
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
[addons]
name=CentOS-5 - Addons
baseurl=http://centos.ustc.edu.cn/centos/5.1/addons/$basearch/
gpgcheck=1
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
[extras]
name=CentOS-5 - Extras
baseurl=http://centos.ustc.edu.cn/centos/5.1/extras/$basearch/
gpgcheck=1
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=1
[centosplus]
name=CentOS-5 - Plus
baseurl=http://centos.ustc.edu.cn/centos/5.1/centosplus/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=2
[contrib]
name=CentOS-5 - Contrib
baseurl=http://centos.ustc.edu.cn/centos/5.1/contrib/$basearch/
gpgcheck=1
enabled=0
gpgkey=http://centos.ustc.edu.cn/centos/RPM-GPG-KEY-CentOS-5
priority=2
其实是修改成：
[base], [addons], [updates], [extras] ... priority=1
[centosplus],[contrib] ... priority=2
Third Party Repos such as rpmforge ... priority=N (where N is > 10 and based on your preference)
五、下载（请对应于你的计算机系统）
i386 [url]http://apt.sw.be/redhat/el5/en/i[/url] ... 6-1.el5.rf.i386.rpm
x86_64 [url]http://apt.sw.be/redhat/el5/en/x[/url] ... 1.el5.rf.x86_64.rpm
俺是i386
附件(16.3KB) rpmforge-release-0.3.6-1.el5.rf.i386.rpm
六、安装密钥 Install DAG's GPG key
rpm --import [url]http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt[/url]
检查一下：rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm（这步不一定必须）
安装：rpm -ivh rpmforge-release-0.3.6-1.el5.rf.*.rpm
俺下载了
附件(1.6KB) RPM-GPG-KEY.dag.txt
七、检查更新：
yum check-update
这步时间可能过长，系统会建立一个primary.xml.gz文件哦。成功后，最后一步吧
八、yum install mplayer*
[root@localhost ~]# yum install mplayer*

2、下载几个必要的软件包（解码器）：
all-20071007.tar.bz2 和 windows-all-20071007.zip
这是 两个编码包的下载地址：
http://www1.mplayerhq.hu/MPlayer/releases/codecs/
mplayer的编码包默认应安装在/usr/local/lib/codecs/中，
(如果装在了其他目录，在装MPlayer时，./configure的参数要指明路径，参数是--with-codecsdir=“包的路径”，--with-win32libdir=“包的路径”)
# tar jxvf all-20071007.tar.bz2
# mkdir /usr/local/lib/codecs/
# mv -f all-20071007/* /usr/local/lib/codecs/ //一定要注意，是把all-20061022中所有的文件复制到/usr/loc-al/lib/codecs中，而不是文件夹，否则编译后不能播放。
# unzip windows-all-20071007.zip
# mkdir /usr/lib/win32
# mv windows-all-20071007/* /usr/lib/win32
# ln -s /usr/local/lib/codecs /usr/lib/win32
九.xmms,当然mplyer也可以播放mp3
# yum install xmms
yum install xmms-mp3
如果需要在运行菜单显示还要安装：
