科学linux:如何使用rpm安装yum？

Question

在科学linux 6.0(RH类似linux)上，我意外地删除了python，所以yum也删除了µ。

如何使用rpm安装yum？

编辑

我试着安装python，但是它以某种方式循环了依赖关系：

rpm -Uvh http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-libs-2.6.5-3.el6.x86_64.rpm
    Retrieving http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-libs-2.6.5-3.el6.x86_64.rpm
    error: Failed dependencies:
            python = 2.6.5-3.el6 is needed by python-libs-2.6.5-3.el6.x86_64

然后：

 rpm -Uvh http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python
-2.6.5-3.el6.x86_64.rpm
Retrieving http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-2.6.5-3.el6.x86_64.rpm
error: Failed dependencies:
        libpython2.6.so.1.0()(64bit) is needed by python-2.6.5-3.el6.x86_64

下载软件包(S)并键入rpm -Uvh <packagenames>作为root用户或sudo rpm -Uvh <packagenames>作为普通用户

我使用rpm -qpR yum-3.2.27-14.el6.noarch.rpm来获取yum的依赖项列表，希望这能一次将它们全部消除：

下载包含以下代码块的所有包：

wget http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-2.6.5-3.el6.x86_64.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-libs-2.6.5-3.el6.x86_64.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-iniparse-0.3.1-2.1.el6.noarch.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/pygpgme-0.1-18.20090824bzr68.el6.x86_64.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-urlgrabber-3.9.1-7.el6.noarch.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/python-pycurl-7.19.0-5.el6.x86_64.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/rpm-python-4.8.0-12.el6.x86_64.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/yum-3.2.27-14.el6.noarch.rpm \
http://ftp2.scientificlinux.org/linux/scientific/6.0/x86_64/os/Packages/yum-metadata-parser-1.1.2-14.1.el6.x86_64.rpm

按以下方式安装：

rpm -Uhv py*.rpm \
   yum*.rpm \
   rpm-py*.rpm
