RHEL6.5更換本地YUM源

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://vault.centos.org/6.0/os/x86_64/Packages/Python-iniparse-0.3.1-2.1.el6.noarch.rpm
wget http://vault.centos.org/6.0/os/x86_64/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm
wget http://vault.centos.org/6.0/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm
wget http://vault.centos.org/6.0/os/x86_64/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 
rpm -ivh 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！
或者直接把下面的記憶體拷貝到CentOS6-Base-163.repo檔案中即可（已經修改好）
# 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.

            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yum是否可用
 
至此，RedHat6可以使用CentOS的yum源線上安裝軟體了！
