我在CentOS（5.3,64位版本）中安装yum时遇到了问题。 我的CentOS yum没有预装，所以我不能安装我需要的其他软件包。 我发现有一篇文章展示了如何在CentOS上安装yum（包括32位和64位），但是这对我来说不起作用。
命令来安装yum
rpm import http://mirror.centos.org/centos-5/5.3/os/x86_64/RPM-GPG-KEY-CentOS-5 rpm -ihv http://mirror.centos.org/centos/5.3/os/x86_64/CentOS/libxml2-2.6.26-2.1.2.7.i386.rpm rpm -ihv http://mirror.centos.org/centos/5.3/os/x86_64/CentOS/libxml2-python-2.6.26-2.1.2.7.x86_64.rpm rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-iniparse-0.2.3-4.el5.noarch.rpm rpm -ihv http://mirror.centos.org/centos-5/5.3/os/x86_64/CentOS/python-sqlite-1.1.7-1.2.1.x86_64.rpm rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/python-urlgrabber-3.1.0-2.noarch.rpm rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/python-urlgrabber-3.1.0-2.noarch.rpm rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/sqlite-3.3.6-2.x86_64.rpm rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/yum-metadata-parser-1.1.2-2.el5.x86_64.rpm rpm -ihv http://mirror.centos.org/centos-5/5.2/os/x86_64/CentOS/yum-3.2.8-9.el5.centos.1.noarch.rpm 当我input命令并input时，抛出错误：
/bin/rpm: /lib/ld-linux.so.2: bad ELF interpreter
你能帮我解决这个问题吗？
预先感谢！
