Red Hat Enterprise Linux 6.3 配置的yum庫

       因爲 redhat 的 yum 在線更新是收費的，若是沒有註冊的話不能使用，若是要使用，需將 redhat 的 yum 卸載後，重啓安裝，再配置其餘源.

一、刪除 redhat 原有 yum

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

二、下載 yum 安裝文件（若是下載時找不到文件，就登陸到：http://mirrors.163.com/centos/6/os/x86_64/ 上查找相應的文件，而後再下載）

# wget http://mirrors.163.com/centos/6/os/x86_64/Packages/yum-3.2.29-81.el6.centos.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-plugin-fastestmirror-1.1.30-40.el6.noarch.rpm
# 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/python-urlgrabber-3.9.1-11.el6.noarch.rpm 

三、安裝yum

# 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    (注意最後兩個包必需同時安裝，不然會相互依賴)

安裝會提示：

warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
error: Failed dependencies:
    python-urlgrabber >= 3.9.1-10 is needed by yum-3.2.29-81.el6.centos.noarch
須要安裝python-urlgrabber依賴（由於系統已經安裝了舊版本，先刪除，再安裝）

# rpm -qa | grep python-urlgrabber

python-urlgrabber-3.9.1-8.el6.noarch

# rpm -e python-urlgrabber-3.9.1-8.el6.noarch
# rpm -ivh python-urlgrabber-3.9.1-11.el6.noarch.rpm

warning: python-urlgrabber-3.9.1-11.el6.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:python-urlgrabber      ########################################### [100%]
[root@localhost Downloads]# rpm -qa | grep python-urlgrabber

再執行下面安裝

# rpm -ivh yum-3.2.29-40.el6.centos.noarch.rpm yum-plugin-fastestmirror-1.1.30-14.el6.noarch.rpm

warning: yum-3.2.29-81.el6.centos.noarch.rpm: Header V3 RSA/SHA1 Signature, key ID c105b9de: NOKEY
Preparing...                ########################################### [100%]
   1:yum-plugin-fastestmirro########################################### [ 50%]
   2:yum                    ########################################### [100%]

安裝成功。

三、更新 repo 文件（目錄 /etc/yum.repos.d/ 下原來的文件都是能夠刪除的）

# mv /etc/yum.repos.d/rhel-source.repo /etc/yum.repos.d/rhel-source.repo.bak 

# touch /etc/yum.repos.d/rhel-debuginfo.repo

# vi /etc/yum.repos.d/rhel-debuginfo.repo

測試一下：

# yum clean all
# update/install vim 測試下
# yum -y install vim

 

四、yum 的相關配置能夠在文件 /etc/yum.conf 中來指定（通常不用修改）

yum下載安裝過的安裝包能夠在目錄  /var/cache/yum/x86_64/$releasever/base/packages 下找到。
