CentOS6.5 upgrade Python to 2.7 and install PIP

1. Download and install python2.7

Preparation before installation:

Yum Install Zlib-devel openssl-devel-y

Note : You must install the Zlib-devel package before compiling the python2.7 installation, or you will receive the following error when installing Setuptools:

Attributeerror: ' Nonetype ' object has no attribute ' decompressobj '

Download the installation:

wget wget Http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2tar XF python-2.7.3.tar.bz2cd python-2.7.3./ Configure--prefix=/usr/local/python2.7make && make install

Establish a soft connection so that the system default Python points to python2.7:

mv/usr/bin/python/usr/bin/python2.6.6 ln-s/usr/local/python2.7/bin/python2.7/usr/bin/python

Troubleshooting Yum incompatibility python2.7 issues:

Sed-i ' S#!/usr/bin/python#!/usr/bin/python2.6.6#g '/usr/bin/yum

2. Install Pip

Install Setuptools:

wget Https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.pypython ez_setup.py

Download install PIP:

wget--no-check-certificate tar zxf 1.5.5.tar.gzpython setup.py Install

Note : The Openssl,openssl-devel package must be installed before compiling and installing Python, otherwise the following error will occur:
