如何撤消“yum remove python”

Question

我有一个带有 ssh 连接的基于 Centos 6 的 VPS。最近想安装python 2.7.2，勇敢的跑了：

yum remove python

这显然删除了 yum 本身正在编写或依赖于 python。

现在我不知道该怎么做，更糟糕的是，我是一个完整的 Linux 新手（命令行或其他方式）。

跑步rpm -iv http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/python-2.6.5-3.el6.x86_64.rpm给出：

Retrieving http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/python-2.6.5-3.el6.x86_64.rpm
Preparing packages for installation...
        package python-2.6.5-3.el6.x86_64 is already installed

它的 x86_64 服务器毫无疑问，因为“uname -a”给出：

Linux xxxxxx 2.6.32-71.29.1.el6.x86_64 #1 SMP Mon Jun 27 19:49:27 BST 2011 x86_64 x86_64 x86_64   GNU/Linux

还有一件事：ls /usr/bin/pyth* -la给出：

lrwxrwxrwx 1 root root    6 Dec  4 20:31 python2 -> python
-rwxr-xr-x 2 root root 4864 Nov 12  2010 python2.6
-rwxr-xr-x 2 root root 4864 Nov 12  2010 python;4edbd894

从CentOS 6 镜像列表中选择一个镜像并使用rpm. 您将需要处理依赖项。幸运的是，我有一个安装了 CentOS 6 x86_64 的裸机。

我对虚拟机进行了快照，运行yum remove python并通过一些循环依赖获得了一些乐趣。最后结果：

# --nodeps: because of circular dependency between python and python-libs
rpm -i --nodeps http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/python-libs-2.6.5-3.el6.x86_64.rpm
rpm -i http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/python-2.6.5-3.el6.x86_64.rpm

# --nodeps: because of circular dependency between yum and yum-plugin-fastestmirror
rpm -i --nodeps http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/yum-plugin-fastestmirror-1.1.26-11.el6.noarch.rpm
rpm -i http://centos.mirrors.hoobly.com/6.0/os/x86_64/Packages/yum-3.2.27-14.el6.centos.noarch.rpm

更换任何你想要的镜子。此外，请确保架构匹配。不过，这应该可以解决问题！

哦还有一件事：如果我是你，我会yum upgrade在你安装完 RPM 后立即运行。
