centos5上用yum安装MPlayer！！！！

网上看到的资料，自己也修改了一下。提供给大家用用。

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
* x86_64

(你可以在 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

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

117 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

Loading "protectbase" plugin
Loading "installonlyn" plugin

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.但是这个包可以用.

/etc/yum.repos.d/CentOS-Base.repo内容示范，你用这个文件替换一下你自己的文件，一般就可以用了，很方便。建议在替换前备份下：
mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
vi /etc/yum.repos.d/CentOS-Base.repo

复制以下内容：


# 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.
