配置网络YUM源

一、网络YUM源   使用163 yum源

1.进入下载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

(sohu yum源: ,使用方法相同)

二、本地yum源   使用光盘yum源

1.挂载光盘
mount -t iso9660 -o loop /dev/cdrom /media/CentOS
2.移除/etc/yum.repos.d目录原有的repo文件
3.创建新repo文件
vi /etc/yum.repos.d/CentOS-Media.repo
加入如下字段:
[c5-media]
name=CentOS-$releasever - Media
baseurl=file:///media/CentOS/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5
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-GPG-KEY-CentOS-5

================================================================

另外一种： redhat linux下配置yum源  

使用redhat linux系统自带的yum源好像要授权，需要费用，用CentOS的源免费，配置简单

1.#cd /etc/yum.repos.d/     #打开源路径

2.#wget  #下载CentOS的源

3.#yum install softwarename

附：CentOS使用的yum源是在/etc/yum.repos.d/目录下的两个文件中进行配置的，其中：

CentOS-Base.repo是配置网络yum源

CentOS-Media.repo是配置本地yum源
