【安裝 Priorities】
參考:http://wiki.centos.org/zh-tw/PackageManagement/Yum/Priorities

解決MPlayer 或 VLC Player.....多媒體套件無法安裝的問題,
因為官方版權的限制所以相關的多媒體套件在官方的套件庫是沒有提供的,所以我們需要安裝第三方套件庫,
同時安裝前也需要安裝 Priorities 套件來設定套件庫參考網站下載優先權,告知 yum 在官方套件庫找不到套件時前往第三方套件庫的順序。

步驟一:安裝 Priorities 套件
官方提供的套件庫,都是比較穩定的。要安裝第三方套件庫來源時就需要安裝 priorities 這個套件確保官方提供的套件庫下載順位在第一位。

CentOS-4 或 CentOS-6:
[root@localhost ~]# yum install yum-plugin-priorities

CentOS-5:
[root@localhost ~]# yum install yum-priorities

步驟二:修改與檢查 priorities.conf
[root@localhost ~]# vi /etc/yum/pluginconf.d/priorities.conf

[main]
enabled=1

步驟三:新增 obsoletes 套件屬性(非必須)
是否取代更新的版號套件
編輯 /etc/yum/pluginconf.d/priorities.conf

[main]
check_obsoletes=1

當 priorities 套件被啟用後,你可以加入下面一行為套件庫增設優先次序:
priority=N

步驟四:修改 CentOS-Base.repo
[root@localhost ~]# vi /etc/yum.repos.d/CentOS-Base.repo

[base]
...
priority=1

[addons]
...
priority=1

[updates]
...
priority=1

[extras]
...
priority=1

[centosplus]
...
priority=2

[contrib]
...
priority=2

 


安裝 RPMforge 第三方套件庫

安裝 RPMforge 套件

請先至 http://pkgs.repoforge.org/rpmforge-release/ 下載最新的 RPMforge 套件庫到你的電腦

[root@localhost ~]# wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.2-2.el5.rf.i386.rpm

安裝
[root@localhost ~]# rpm -ivh rpmforge-release-0.5.2-2.el5.rf.i386.rpm

步驟四:修改 rpmforge.repo

# vi /etc/yum.repos.d/rpmforge.repo

[rpmforge]
...
priority=10

[rpmforge-extras]
...
