Python 2.6 to Python 2.7, python2.6

Python 2.6 to Python 2.7, python2.6

Preface

To install Python 2.7.13 in CentOS 6.8, upgrade Python to 2.7.13 as required by the software version. In addition, the production environment is still dominated by RHEL 6, most of the Internet automated O & M platforms are recommended to operate on Python 2.7.x + CentOS 6.x. If Python 2 or Python 3 is selected, you can find a proper combination.

Simple Installation

Because yum configuration will be automatically improved in Versions later than Python 2.7.13, you do not need to refer to previous online articles to modify other places.
