Centos6.6 Upgrade Python version

CentOS native Python is 2.6.6 and can be viewed by the following command

# python-v 2.6. 6

1. Download the Python version you need

To download the required version of the https://www.python.org/downloads/website, the current version of Linux used is. tgz or. tar.xz version.

2. Unzip the download file

Taking Tar.xz as an example

# xz-d PYTHON-2.7.8.TAR.XZ#TAR-XVF Python-2.7.8.tar

3. Compiling & Installing

Because the compilation requires GCC support, if it is not installed, install GCC, #yum installed GCC

# CD Python-2.7.8#./configure#make all           #make install#make clean#make Distclean

4, cancel the original link, create a new version of the link

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

5. Check the current version of Python

# python-v 2.7. 8

6, because Yum does not have compatible python2.7, it is necessary to change the red part below from #!/usr/bin/python to #!/usr/bin/python2.6.

Nano/usr/bin/yum

#!/usr/bin/python

Modified to:

#!/usr/bin/python2.6
