redhat as4上安装yum

一、安装篇    
  下载下载yum软件并安装
    wget      tar zxvf yum_forAS4.tar.gz
yum_forAS4/
yum_forAS4/CentOS-Base.repo
yum_forAS4/python-elementtree-1.2.6-7.el4.rf.i386.rpm
yum_forAS4/python-urlgrabber-2.9.7-1.2.el4.rf.noarch.rpm
yum_forAS4/yum-2.4.2-0.4.el4.rf.noarch.rpm
yum_forAS4/sqlite-2.8.16-1.2.el4.rf.i386.rpm
yum_forAS4/python-sqlite-1.0.1-1.2.el4.rf.i386.rpm
    cd yum_forAS4
    rpm -ivh *.rpm
    cp CentOS-Base.repo /etc/yum.repos.d/
    执行如下命令导入GPG Key
    rpm --import -CentOS-4
   CentOS-Base.repo这里默认的 已经不存在YUM源，将地址改为即可。
   wget CentOS-Base.repo
    yum安装完毕(以上是针对32位系统的安装)。
二、问题篇
      1、 系统问题，输入yum提示：
    
 There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
 /usr/lib/python2.3/site-packages/cElementTree.so: cannot open shared object file: No such file or directory
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.3.4 (#1, Feb 18 2008, 17:16:53) 
[GCC 3.4.6 20060404 (Red Hat 3.4.6-9)]
If you cannot solve this problem yourself, please go to 
the yum faq at:

   问题是之前安装的python-elementtree-1.2.6-7.el4.rf.i386.rpm包是针对32位操作系统的；
   安装python-elementtree-1.2.6-7.el4.rf.x86_64.rpm即可；下载地址如下：

     2、python版本问题，
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6.1 (r261:67515, Aug 7 2010, 11:36:17)
[GCC 4.1.2 20080704 (Red Hat 4.1.2-44)]
If you cannot solve this problem yourself, please go to
the yum faq at:
 
      错误原因：错误信息描述为 yum 所依赖的python 不相符；
     查找yum文件，并编辑此py文件

             which yum

             /usr/bin/yum

             vi /usr/bin/yum

             将#!/usr/bin/python改为#!/usr/bin/python2.3,保存；（补充：yum基于python写的）。
