Redhat 6.2系統下yum的配置說明

對於redhat版本的系統來講若是想使用yum的在線安裝功能是須要花錢的，做爲IT屌絲如何能夠無償使用yum呢？答案是能夠藉助於centos系統開源包來給咱們的yum工具作相應配置就可使用。

一、刪除redhat原有的yum源 

    
    
    
    
    

     
     
     
     
     

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

二、下載新的yum安裝包  ， 這裏咱們使用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.rpmwget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-3.2.29-69.el6.centos.noarch.rpmwget http://mirror.centos.org/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-30.el6.noarch.rpm

三、安裝yum軟件包 

    
    
    
    
    

     
     
     
     
     

     
     
     
     
     

     
     
     
     
     

     
     
     
     
     

     
     
     
     
     

    
    
    
    
    
rpm -ivh  python-iniparse-0.3.1-2.1.el6.noarch.rpm rpm -ivh  yum-metadata-parser-1.1.2-16.el6.x86_64.rpmrpm -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塊兒同時安裝，不然會提示相互依賴，安裝失敗。

四、更改yum源  #咱們使用網易的CentOS鏡像源 

     
     
     
     
     

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

      
      
      
      
      

     
     
     
     
     
cd /etc/yum.repos.d/ wget  http://mirrors.163.com/.help/CentOS6-Base-163.repo vi CentOS6-Base-163.repo 

編輯文件，把文件裏面的$releasever所有替換爲版本號，即6 最後保存，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.combaseurl=http://mirror.centos.org/centos/6/os/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=osgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#released updates [updates]name=CentOS-6 - Updates - 163.combaseurl=http://mirror.centos.org/centos/6/updates/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updatesgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that may be useful[extras]name=CentOS-6 - Extras - 163.combaseurl=http://mirror.centos.org/centos/6/extras/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extrasgpgcheck=1gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#additional packages that extend functionality of existing packages[centosplus]name=CentOS-6 - Plus - 163.combaseurl=http://mirror.centos.org/centos/6/centosplus/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplusgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6#contrib - packages by Centos Users[contrib]name=CentOS-6 - Contrib - 163.combaseurl=http://mirror.centos.org/centos/6/contrib/$basearch/#mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contribgpgcheck=1enabled=0gpgkey=http://mirror.centos.org/centos/RPM-GPG-KEY-CentOS-6

五、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,以提升搜索安裝軟件的速度 yum install vim*    #測試域名是否可用 

至此，Redhat6可使用CentOS的yum源在線安裝軟件了！

　　 

主要的鏡像地址：

http://mirror.centos.org/centos/6/

http://mirrors.163.com/centos/6/

163鏡像的內容不夠全，可是速度快，能夠優先考慮配置成163鏡像，若是報錯是404 not found，再配置成centos鏡像。
