x86_64位yum的安装

一、安装yum包

rpm -ihv yum-2.4.2-0.4.el4.rf.noarch.rpm

二、修改yum包的安装源

cd /etc/yum.cd /etc/yum.repos.d/.d/

mv CentOS-Base.repo CentOS-Base.repo.bak

vi CentOS-Base.repo

输入下面的内容

# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#

三、更新下源

yum -y upate

结果发现报错如下

[root@sec yum.repos.d]# yum -y update

Setting up Update Process

Setting up repositories

http://mirrors.sohu.com/centos/4AS/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404: Not Found

Trying other mirror.

Cannot open/read repomd.xml file for repository: base

failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.

Error: failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.

修改源的文件

把文件里面的所有$releasever修改为4

类似于baseurl=http://mirrors.sohu.com/centos/$releasever/extras/$basearch/

修改为baseurl=http://mirrors.sohu.com/centos/4/extras/$basearch/

然后退出保存

然后yum 就ok了

yum -y update 即把所有的可更新的rpm都更新,包括内核
