[linux]centos7 升级python后出现“No module named yum”错误

公司服务器重新安装系统后，手动升级python2.7.5到2.7.15，安装完python在更新系统python版本的过程中无意删除了系统自带的版本，导致后来在执行yum命令的时候出现了错误

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:
2.7.15 (default, May 21 2018, 11:43:18)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-16)]

If you cannot solve this problem yourself, please go to
the yum faq at:
  http://yum.baseurl.org/wiki/Faq

考虑到原来系统使用的python版本为2.7.5，手动编译安装python2.7.5版本后还是出现该问题。

解决方法：

下载下列文件：
python-2.4.3-46.el5_8.2.i386.rpm
python-devel-2.4.3-46.el5_8.2.i386.rpm
python-libs-2.4.3-46.el5_8.2.i386.rpm
