tar -xvf Python-3.6.5.tgz
cd Python-3.6.5
./configure --enable-shared
--prefix=/usr/local/python3.6.5
make
make install
修改系统的默认python版本
ln -fs /usr/local/python3.6.5/bin/python3 /usr/bin/python
ln -fs /usr/local/python3.6.5/lib/libpython3.6m.so.1.0 /usr/lib64/libpython3.6m.so.1.0
修改yum配置文件（否则yum无法正常运行）/usr/bin/yum，改为原来系统默认的版本
将第一行的#!/usr/bin/python修改为系统原有的python版本地址#!/usr/bin/python2.6
