配置yum

搭建本地的yum，yum主要是解决了包的依赖关系.

1.配置文件./etc/yum.repos.d/rhel-debuginfo.repo

yum配置文件必须以repo结尾，前面的无所谓，rhel-debuginfo.repo 是配置文件模板

2.配置local.repo配置文件

[root@oracle10g yum.repos.d]# cp rhel-debuginfo.repo local.repo

[root@oracle10g yum.repos.d]# ll

total 12

-rw-r--r-- 1 root root 254 Oct 22 14:51 local.repo

-rw-r--r-- 1 root root 254 Aug 4 2009 rhel-debuginfo.repo

[root@oracle10g yum.repos.d]# more local.repo

[rhel-debuginfo]

name=Red Hat Enterprise Linux $releasever - $basearch - Debug

baseurl=ftp://ftp.redhat.com/pub/redhat/linux/enterprise/$releasever/en/os/$basearch/De

buginfo/

enabled=0

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

修改local.repo,file:///media/Server是mount上去的cdrom (mount /dev/cdrow /media)

修改后local.repo文件内容为:

[root@oracle10g yum.repos.d]# cat local.repo

[rhel-debuginfo]

name=Red Hat Enterprise Linux local repo

baseurl=file:///media/Server

enabled=1

gpgcheck=1

gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release

清空yum缓存

[root@oracle10g yum.repos.d]# yum clean all

Loaded plugins: rhnplugin, security

Repository rhel-debuginfo is listed more than once in the configuration

Cleaning up Everything

3.yum使用
