Linux安装python:
yum install zlib -y
yum install zlib-devel -y
yum install readline-devel -y
yum install openssl -y
yum install openssl-devel -y
yum install sqlite-devel -y
wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz
tar -xvf Python-2.7.11.tgz
cd Python-2.7.11
./configure
make
make install
which python
mv /usr/bin/python /usr/bin/python2.6
ln -s /usr/local/bin/python2.7 /usr/bin/python
whereis python
whereis yum
vi /usr/bin/yum
第一行改成：#!/usr/bin/python2.6即可，由于yum不兼容python2.7所以改成2.6即可
