Python Learning notes-lap environment

in order to use some automated operations tools and project needs, it is necessary to learn the language of Pythoninstall Python 2.7.9 on Linux CentOS 6.6---turn from Dudu

CentOS 6.6 comes with Python 2.6.6, while compiling LLVM requires more than Python 2.7.

Checking for Python .../usr/bin/pythonchecking for Python >= 2.7 ... Not foundconfigure:error:found python 2.6.6 (/usr/bin/python); Required >= 2.7

The newest in Yum is also Python 2.6.6, which can only download Python 2.7.9 source code to compile and install itself.

The procedure is as follows:

1) Install Devtoolset

Yum Groupinstall "Development tools"

2) Install the packages needed to compile Python

Yum Install Zlib-develyum install Bzip2-develyum install Openssl-develyum install Ncurses-develyum install Sqlite-devel

3) Download and unzip the source code of the Python 2.7.9

4) Compiling and installing Python 2.7.9

./configure--prefix=/usr/localmake && make Altinstall

5) Point python command to Python 2.7.9

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

6) Check Python version
