Install python3.5 above on CentOS

First, the preparatory work:

Yum Install Zlib-devel

Yum Install Openssl-devel

Second, installation python3.5

wget https://www.python.org/ftp/python/3.5.3/Python-3.5.3.tgz

TAR-ZXVF python-3.5.3.tgz

CD Python-3.5.3

./configure--prefix=/usr/local/python3--enable-shared

Make && make install

Iii. replacing Python in the system

Mv/usr/bin/python Python.bak

Ln-s/usr/local/python3.5/bin/python3/usr/bin/python

Since changing the system default Python will affect Yum, you need to modify the following two files:

/usr/bin/yum and/usr/libexec/urlgrabber-ext-down

Iv. installation of Setuptools

wget--no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-19.6.tar.gz#md5= C607dd118eae682c44ed146367a17e26

TAR-ZXVF setuptools-19.6.tar.gz

CD setuptools-19.6

Python3 setup.py Build

Python3 setup.py Install

(If there is an error: Runtimeerror:compression requires the (missing) Zlib module, you need to install Yum install Zlib-devel, after installation to recompile python3.5:

Make && make install)

Five, install Pip

wget--no-check-certificate https://pypi.python.org/packages/source/p/pip/pip-8.0.2.tar.gz#md5= 3a73c4188f8dbad6a1e6f6d44d117eeb

TAR-ZXVF pip-8.0.2.tar.gz

CD pip-8.0.2

Python3 setup.py Build

Python3 setup.py Install

To install package tests using PIP:

If an error occurs, the Yum install Openssl-devel is missing, and the python3.5 (Make&&make install) will need to be recompiled as soon as the installation is complete.
