CentOS 5下使用yum安装mplayer

编译安装MPlayer好麻烦.其实centos也可以用yum安装 MPlayer.
(rhel也可用)

看一下centos 5的部分:

CentOS 5

首先确定你安装了ProtectBase
.

Protectbase

yum-protectbase在CentOS 5包仓库里面有提供:

#yum install yum-protectbase

在CentOS 5里面这个插件默认启动 .
编辑/etc/yum.repos.d/CentOS-Base.repo ,
在 [base]
、[update]
、[centosplus]
段末加上一行:

protect=1

让 [centosplus] 段失效如下:

enabled=0

编辑/etc/yum.repos.d/CentOS-Base.repo ，
在其它段的最后加上如下一行：

protect=0

rpmforge

下载rpmforge-release包.选择下面两个的其中一个, 依赖于你的机器.如果不能确定用哪一个用以下命令确定 uname -i

i386 http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm


x86_64 http://apt.sw.be/redhat/el5/en/x86_64/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm


(你可以在 http://dag.wieers.com/packages/rpmforge-release/

找到rpmforge-release包的完全列表，但是推荐使用上面列出两个中的一个).
安装DAG's GPG key

#rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt

校验你下载的包

#rpm -K rpmforge-release-0.3.6-1.el5.rf.*.rpm

安全警告: rpmforge-release包把GPG keys注射到你的RPM数据库中. 只要你验证包和相信Dag,它应该是安全的.
安装包

#rpm -ivh rpmforge-release-0.3.6-1.el5.rf.*.rpm

这一步会加入yum仓库配置文件，注射合适的GPG keys.

用以下命令测试:

#yum check-update

应该会有以下两行输出:

Loading "protectbase" plugin

...

76 packages excluded due to repository protections

上面的数字可能不同, 但应该有几种包显示会排除在外.

如果是这样大概它可以运转了，试着你这样安装一些东西 ：

#yum install mplayer


PS: 
发现一个MPlayer的另一个前端SMPlayer也可以使用.没有编译好的RPM包.但是这个 SUSE的RPM包
可以用.

[b]/etc/yum.repos.d/CentOS-Base.repo内容示范：

# 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.

ps:当然，要想播放rm/rmvb还需要将codecs和wincodecs解压到/usr/lib,就是把codecs解压到/usr/lib/codecd, wincodecd解压到/usr/lib/wincodecs。这点这里
有说
