RedHat Enterprise Linux 6.X 使用Centos 6 的yum源

思路：解除安裝redhat自帶yum，然後下載下傳centos的yum，安裝後修改配置檔案

1、首先到http://mirrors.163.com/centos下載下傳軟體包

x86 位址：http://mirrors.163.com/centos/6/os/i386/Packages/

x86_64 位址：http://mirrors.163.com/centos/6/os/x86_64/Packages/

必要下載下傳的軟體包有（以64位系統為例）：

a python-iniparse-0.3.1-2.1.el6.noarch.rpm

b yum-3.2.29-40.el6.centos.noarch.rpm

c yum-metadata-parser-1.1.2-16.el6.x86_64.rpm

d yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

下載下傳指令：

wget http://mirrors.163.com/centos/6/os/x86_64/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-metadata-parser-1.1.2-16.el6.x86_64.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-40.el6.centos.noarch.rpm wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :版本不一定要最新的

2、解除安裝RedHat自帶的yum

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

注：a、xargs是一條Unix和類Unix作業系統的常用指令。它的作用是将參數清單轉換成小塊分段傳遞給其他指令，以避免參數清單過長的問題

b、--nodeps 強制解除安裝,不管依賴性

3、安裝下載下傳的centos的yum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-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

[注] :最後2個需要一起安裝，否則會出現依賴性錯誤

4、到http://mirrors.163.com的centos幫助文檔中下載下傳CentOS6-Base-163.repo檔案，存放到/etc/yum.repo.d中

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

5、編輯CentOS6-Base-163.repo檔案，将其中的$releasever更改為centos的版本号

下面是修改好的：

# 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://mirrors.163.com/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://mirrors.163.com/centos/6/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=updates #additional packages that may be useful [extras] name=CentOS-6 - Extras - 163.com baseurl=http://mirrors.163.com/centos/6/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=extras #additional packages that extend functionality of existing packages [centosplus] name=CentOS-6 - Plus - 163.com baseurl=http://mirrors.163.com/centos/6/centosplus/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=centosplus enabled=0 #contrib - packages by Centos Users [contrib] name=CentOS-6 - Contrib - 163.com baseurl=http://mirrors.163.com/centos/6/contrib/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=6&arch=$basearch&repo=contrib

6、yum clean all清除原有緩存

7、yum makecache 擷取yum清單
