Step Details
1, CentOS Python installation dependencies
yum groupinstall "Development tools" yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel . .
2, download the source package and compile Python3X
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz tar -zxvf Python-3.6.1.tgz cd Python-3.6.1 ./configure --prefix=/usr/local/python36 yum -y install zlib* openssl-devel make && make install . .
3, the #! / Usr / bin / python changed to #! / Usr / bin / python2
sed -i 's/#!/usr/bin/python/#!/usr/bin/python2.6/' /usr/bin/yum （可选）sed -i 's/#! /usr/bin/python/#! /usr/bin/python2/' /usr/libexec/urlgrabber-ext-down . .
4, replace python2 / usr / bin / into the python3
mv /usr/bin/python /usr/bin/pythonold cp /usr/local/python36/bin/python3.6 /usr/bin/python cp /usr/local/python36/bin/pip3 /usr/bin/pip3 . .
