1. 准备环境

[code] yum install wget xz sqlite-devel zlib-devel bzip2-devel openssl-devel ncurses-devel readline-devel gcc-c++ gcc -y

2. 下载python 3代码包

[code]wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tar.xz

3. 解压，编译安装

[code]tar xf Python-3.6.3.tar.xz -C /usr/local/src/
cd /usr/local/src/Python-3.6.3/
./configure --prefix=/usr/local/python3
make -j 8 && make install

4. 做软链

[code]ln -s /usr/local/python3/bin/python3.6 /usr/local/bin/python3

ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip
