CentOS编译安装Python3

一、准备编译环境

~$ sudo yum install -y zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

二、编译安装Python3

Python源码官网下载地址：https://www.python.org/downloads/source/

2.1 获取源码

本例中使用Python-3.6.2版本：

~$ wget https://www.python.org/ftp/python/3.6.2/Python-3.6.2.tgz
~$ tar -zxvf Python-3.6.2.tgz

2.2 编译安装

~$ cd Python-3.6.2
~$ ./configure prefix=/usr/local/python3
~$ make
~$ sudo make install
~$ sudo ln -s /usr/local/python3/bin/python3 /usr/bin/python3
~$ sudo ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

2.3 校验版本

~$ python3 --version
