Centos5.x under upgrade python to python version 2.7 tutorial

First go to the official website to download python version 2.7.3, compile and install

$wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

$tar zxvf Python-2.7.3.tgz

$cd Python-2.7.3

$./configure

$make && make install

It then backs up the original python and makes a soft connection to python2.7 to the new location

$mv /usr/bin/python /usr/bin/python.bak

$ln -s /usr/local/bin/python2.7 /usr/bin/python

$python -V

The version prompt is 2.7.3
Change yum to make it work

$vim vim /usr/bin/yum

Change #/usr/bin/python to #/usr/bin/python2.4 so yum works

Install easy_install

$yum install python-setuptools

Then install python-setuptools go to pypi website and download python-setuptools. The version should be consistent with the version of yum, otherwise it will appear when running:

$ easy_install rsa

Traceback (most recent call last):

  File "/usr/bin/easy_install", line 5, in <module>

    from pkg_resources import load_entry_point

ImportError: No module named pkg_resources

And then:

$wget http://pypi.python.org/packages/source/s/setuptools/setuptools-0.6c5.tar.gz

$tar zxvf setuptools-0.6c5.tar.gz

$cd setuptools-0.6c5

$python setup.py install

This makes it easy to install python libraries using easy_install
