CentOS installation of python2.7.1 and Yum can not be used after loading __python

Recently their Redhat python upgraded Python to 2.7, but found that Yum can not use, found a workable solution, we can refer to, reprinted a Netizen's article, the pro-test effective.

Reproduced from: http://www.cnblogs.com/theitnotes/p/4162882.html

Because CentOS's Yum is developed using python2.4.x, a later version of the Python installation is not supported, so manual installation is required.

First install the dependency pack and run the following command

Yum install-y gcc make

Yum install-y libxml2

Yum Install-y libxslt

Yum install-y pkgconfig Zlib-devel

Yum Install-y libgcrypt-devel

#备份文件/usr/bin/python (be sure to back up or Yum will not run after Setup is complete)
mkdir ~/tmp
Cp/usr/bin/python ~/tmp
Execute the following command to download and install the python:
wget http://www.python.org/ftp/python/2.7.1/Python-2.7.1.tgz

Tar zxvf python-2.7.1.tgz

CD Python-2.7.1

./configure--prefix=/usr/lib/python2.7--with-threads--enable-shared
Make;make Install

Cp/usr/lib/python2.7/bin/python/usr/bin/python
cp/usr/lib/python2.7/bin/python2.7/usr/bin/
cp/usr/lib/python2.7/lib/libpython2.7.so.1.0/usr/lib/

This python2.7.1 installation is complete.

However, if you run Yum,yum now, there will be a run-time error because Yum only supports the python2.4.x version

You need to overwrite the previously backed up Python file to/usr/bin/python2.4 (when I installed python2.4 also became a python2.7 version) so to do the following, just in case the backup of Python copy to/usr/bin/ python2.4

CP ~/tmp/python/usr/bin/python2.4

Modify/usr/bin/yum

Vi/usr/bin/yum

The first line of

#!/usr/bin/python

Amended to

#!/usr/bin/python2.4

Then save, yum to fix.
