Centos updates python 2.7.3

First, download the source tar package

Linux download tool wget can be downloaded as follows:

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

Download after the completion of the download directory, decompression

tar -zxvf Python-2.7.3.tgz

Go to the unzipped folder

cd Python-2.7.3

Create a folder named python27 in /usr/local before compiling (as the python installation path to avoid overwriting older versions)

mkdir /usr/local/python2.7.3

Compile the installation in the unzipped directory

./configure --prefix=/usr/local/python2.7.3
make
make install

Instead of overwriting the old version, change the original /usr/bin/python link to something else

mv /usr/bin/python /usr/bin/python_old

Create a link to the new version of python

ln -s /usr/local/python2.7.3/bin/python2.7 /usr/bin/python

This is the time to type in

python

The new version of python is displayed
