yum 本地源及网络源的配置汇总
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------

yum 本地源的配置
[root@jesse ~]# cd /etc/yum.repos.d/
[root@jesse yum.repos.d]# ls
CentOS-Base.repo  CentOS-Media.repo
[root@jesse yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.BAK
[root@jesse yum.repos.d]# ls
CentOS-Base.repo.BAK  CentOS-Media.repo
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------
[root@jesse yum.repos.d]# vi CentOS-Media.repo   
#本地yum源修改成以下配置文件即可
# 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:///mnt/
gpgcheck=0
enabled=1

#wq 保存并退出
#/mount /dev/cdrom mnt

网络源的配置详解：
[root@jesse ~]# cd /etc/yum.repos.d/
[root@jesse yum.repos.d]# ls
CentOS-Base.repo  CentOS-Media.repo

[root@jesse yum.repos.d]# vi CentOS-Base.repo
#以下是我修改好的网络源
#改动地点：1注释掉了mirrorlist开头得行，打开baseurl开头的行2:将mirror.centos.org修改成了mirrors.sohu.com
#批量替换方法:vi 命令模式下输入%s/mirror.centos.org/mirrors.sohu.com/g

默认情况下：yum 安装好后的rpm包会被自动清除，如果我们想不自动清除的话，
[root@jesse ~]# vi /etc/yum.conf
[main]
cachedir=/var/cache/yum
keepcache=1     #将这里的0修改为1
debuglevel=2
#保存退出
#我们安装好后的软件存放的位置：/var/cache/yum/base/packages
