Redhat 6.2系統下yum的配置說明

zzy020128發表於2015-08-12
對於redhat版本的系統來說如果想使用yum的線上安裝功能是需要花錢的,作為IT屌絲如何可以免費使用yum呢?答案是可以藉助於centos系統開源包來給我們的yum工具做相應配置就可以使用。


1、刪除redhat原有的yum源 
rpm -aq | grep yum|xargs rpm -e --nodeps 
2、下載新的yum安裝包  ,這裡我們使用CentOS的yum源 
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm 
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpm
wget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
3、安裝yum軟體包 
rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm 
rpm -ivh  yum-metadata-parser-1.1.2-16.el6.x86_64.rpm
rpm -ivh  yum-3.2.29-69.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm
注意:最後兩個安裝包要放在一起同時安裝,否則會提示相互依賴,安裝失敗。
4、更改yum源  #我們使用網易的CentOS映象源 
cd /etc/yum.repos.d/ 
wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo 
vi CentOS6-Base-163.repo 
編輯檔案,把檔案裡面的$releasever全部替換為版本號,即6 最後儲存,或者直接用複製下面的CentOS6-Base-163.repo 
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-6 - Base - 163.com
baseurl=http://mirror.centos.org/centos/6/os/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=os
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#released updates 
[updates]
name=CentOS-6 - Updates - 163.com
baseurl=http://mirror.centos.org/centos/6/updates/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#additional packages that may be useful
[extras]
name=CentOS-6 - Extras - 163.com
baseurl=http://mirror.centos.org/centos/6/extras/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras
gpgcheck=1
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-6 - Plus - 163.com
baseurl=http://mirror.centos.org/centos/6/centosplus/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplus
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
#contrib - packages by Centos Users
[contrib]
name=CentOS-6 - Contrib - 163.com
baseurl=http://mirror.centos.org/centos/6/contrib/$basearch/
#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contrib
gpgcheck=1
enabled=0
gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6
5、清理yum快取 
yum clean all 
yum makecache     #將伺服器上的軟體包資訊快取到本地,以提高搜尋安裝軟體的速度 
yum install vim*    #測試域名是否可用 
至此,Redhat6可以使用CentOS的yum源線上安裝軟體了!
   
主要的映象地址:
http://mirror.centos.org/centos/6/
http://mirrors.163.com/centos/6/
163映象的內容不夠全,但是速度快,可以優先考慮配置成163映象,如果報錯是404 not found,再配置成centos映象。
