redhat6.2yum源配置方法

一，配置本地yum

1，掛載光盤

mount /dev/cdrom/mnt/media

2,新建本地yun源的配置文件

vi /etc/yum.repos.d/local.repo

加入以下信息：

[Local]

name=Local

baseurl=file:///mnt/media

enable=1

gpgcheck=0

二，配置第三方yum

1.刪除redhat 原有的yum

rpm -aq|grep yum|xargs rpm -e --nodeps

2.下載yum 安裝文件

Wget -c http://mirrors.163.com/centos/6.4/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm

wget -c http://mirrors.163.com/centos/6.4/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

wget -c http://mirrors.163.com/centos/6.4/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

wget -c http://mirrors.163.com/centos/6.4/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm

3.安裝yum 軟件包

(1)rpm -ivh python-iniparse-0.3.1-2.1.el6.noarch.rpm

(2)rpm -ivh yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

(3) 兩個一起安裝先後順序不要亂(中間50%正常)

rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpmyum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

4、更改yum源 #我們使用網易的CentOS鏡像源

(1)清空yum倉庫

# cd /etc/yum.repos.d/

#rm -rf *

(2)設置源

# wget http://mirrors.163.com/.help/CentOS6-Base-163.repo

# vi CentOS6-Base-163.repo

編輯文件，把文件裡面所有的$releasever全部替換為你得版本號，即6.4 最後保存！或者直接把下面的內存拷貝到CentOS6-Base-163.repo文件中即可（已經修改好）

5、清理yum緩存

# yum clean all

# yum makecache #將服務器上的軟件包信息緩存到本地,以提高搜索安裝軟件的速度

# yum installvim* #測試域名是否可用

至此，Redhat6可以使用CentOS的yum源在線安裝軟件了！

6.使用 # yum update

或 # yum upgrade 升級系統

注：兩個命令區別：

# yum update

升級所有包，改變軟件設置和系統設置,系統版本內核都升級

# yum -y upgrade

升級所有包，不改變軟件設置和系統設置，系統版本升級，內核不改變
