redhat5.4更改免费centos yum源 | 无限星辰技术博-专业互联网技术支持

由于，redhat企业版yum为收费项目，所以更换免费的源，这样在架设服务器的时候缺少某些组件可以用yum来进行添加，方便快捷，其实yum的速度没有太慢的，下面我将为大家介绍如何快速的修改yum源。
一、删除原yum所有组件

rpm -qa | grep yum | xargs rpm -e --nodeps #这条代码将删除redhat自带的yum

二、下载yum组件reh5-centos
rpm包已经有了，自己下载解压

[root@localhost yum]# ll
total 1108
-rw-r--r-- 1 root root 34394 Feb 25 09:46 python-iniparse-0.2.3-4.el5.noarch.rpm
-rw-r--r-- 1 root root 1026405 Feb 25 09:45 yum-3.2.22-26.el5.centos.noarch.rpm
-rw-r--r-- 1 root root 19145 Feb 25 09:46 yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm
-rw-r--r-- 1 root root 26053 Feb 25 09:41 yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm

三、下面将要安装着四个软件包，切记按照我的安装顺序来，否则会出现报错，切记~

cd /tools/yum
rpm -ivh python-iniparse-0.2.3-4.el5.noarch.rpm
rpm -ivh yum-metadata-parser-1.1.2-3.el5.centos.i386.rpm
rpm -ivh yum-3.2.22-26.el5.centos.noarch.rpm yum-fastestmirror-1.1.16-14.el5.centos.1.noarch.rpm

四、下面下载yum的配置文件，点击下载CentOS-Base163
上面的包是为redhat5.4准备的，如果你用不了的话，就把下面的代码写到CentOS-Base.repo中保存在
/etc/yum.repos.d/

# 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.

# If the mirrorlist= does not work for you, as a fall back you can try the

# remarked out baseurl= line instead.

# [base]

name=CentOS-$releasever – Base

baseurl=http://centos.ustc.edu.cn/centos/$releasever/os/$basearch/
