Upgrade python2.6.6 to 2.7.x and python2.6.62.7.x

Upgrade python2.6.6 to 2.7.x and python2.6.62.7.x

1. Download python2.7.x

Wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz

2. decompress and compile and install

Tar-zxvf Python-2.7.6.tgz & cd Python-2.7.6 &./configure & make all & make install & make clean & make distclean

3. Check Installation

/Usr/local/bin/python2.7-V

4. Create a soft connection and point

Mv/usr/bin/python/usr/bin/python2.6.6

Ln-s/usr/local/bin/python2.7/usr/bin/python

5. Check

Python-V

6. Notes for using yum

After the system Python soft link points to Python 2.7, yum cannot work properly because yum is incompatible with Python. We need to specify the Python version of yum.

Vim/usr/bin/yum: add the header #! /Usr/bin/python #! /Usr/bin/python2.6.6 (just backed up)
