RHEL 6.0使用CentOS yum源

標籤：

引言：由於RHEL的yum線上更新是收費的，如果沒有註冊的話是不能使用的，即不能線上安裝軟體。在這種情況下，想使用RHEL系統，還想用yum源來線上安裝軟體，有沒有辦法？答案是有辦法，請往下看！

1、刪除RHEL原有的yum
            rpm -aq|grep yum|xargs rpm -e --nodeps  #刪除

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/6.0/os/i386/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm
         wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-metadata-parser-1.1.2-14.1.el6.i686.rpm
         wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
         wget http://mirror.centos.org/centos/6.0/os/i386/Packages/yum-plugin-fastestmirror-1.1.26-11.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-1.1.2-14.1.el6.i686.rpm
         rpm -ivh  yum-3.2.27-14.el6.centos.noarch.rpm  yum-plugin-fastestmirror-1.1.26-11.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  #編輯檔案
   把檔案裡面的$releasever全部替換為版本號碼，即6 最後儲存！

或者直接把下面的記憶體拷貝到CentOS6-Base-163.repo檔案中即可（已經修改好）

1 # CentOS-Base.repo
2#
3# The mirror system uses the connecting IP address of the client and the
4# update status of each mirror to pick mirrors that are updated to and
5# geographically close to the client. You should use this for CentOS updates
6# unless you are manually picking other mirrors.
7#
8# If the mirrorlist= does not work for you, as a fall back you can try the
9# remarked out baseurl= line instead.
10#

5、yum clean all     #清理yum緩衝
            yum makecache     #將伺服器上的軟體包資訊緩衝到本地,以提高搜尋安裝軟體的速度
            yum install vim*  #測試yum是否可用
 
至此，Redhat6可以使用CentOS的yum源線上安裝軟體了！
