Installation of python2.7.1 under CentOS and the problem of Yum not available after loading

Reprinted from Http://blog.163.com/[email protected]/blog/static/164767406201221614650717/

Since the CentOS Yum is developed using the python2.4.x, it does not support a later version of Python installation, so a manual installation is required.

Install the dependency package first, 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 the installation is complete)
mkdir ~/tmp
Cp/usr/bin/python ~/tmp
Execute the following command to download and install 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

The previously backed up Python file needs to be overwritten to/usr/bin/python2.4 (python2.4 also becomes the python2.7 version when I install it) so just in case the following command is executed, copy the backup Python to the/usr/bin/ python2.4

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

Modify/usr/bin/yum

Vi/usr/bin/yum

The first line of the

#!/usr/bin/python

Revision changed to

#!/usr/bin/python2.4

Then save, yum fix.
