配置yum源（163源、sohu源、cd源）

一、使用163 yum源

1.进入http://mirrors.163.com/.help/centos.html下载CentOS-Base-163.repo, 放入/etc/yum.repos.d/

2.运行yum makecache生成缓存

3.yum search softwarename 查找软件

4.yum list softwarename 列出已装软件

5.yum install softwarename 安装软件

6.yun remove softwarename 卸载软件

二、使用sohu yum源

地址 http://mirrors.shou.com,使用方法与163的相同

三、使用光盘yum源

1.挂载光盘

mount -t iso9660 -o loop /dev/cdrom /media/CentOS

2.对/etc/yum.repos.d目录改名

3.创建新yum.repo.d文件

vi /etc/yum.repos.d/iso.repo

加入如下字段:

[iso]

name=iso

baseurl=file:///media/Fedora 12 i386 DVD/

gpgkey=file:///media/Fedora 12 i386 DVD/

enabled=1

gpgcheck=0

4.刷新repos

yum makecache

参考 /etc/yum.repos.d/CentOS-Media.repo文件

# CentOS-Media.repo

#

# This repo is used to mount the default locations for a CDROM / DVD on

# CentOS-5. You can use this repo and yum to install items directly off the

# DVD ISO that we release.

#

# To use this repo, put in your DVD and use it with the other repos too:

# yum --enablerepo=c5-media [command]

#

# or for ONLY the media repo, do this:

#

# yum --disablerepo=* --enablerepo=c5-media [command]

[c5-media]

name=CentOS-$releasever - Media

baseurl=file:///media/CentOS/

file:///media/cdrom/

file:///media/cdrecorder/

gpgcheck=1

enabled=0

gpgkey=

file:///etc/pki/rpm-gpg/RPM
