centos python2.7安装

1.下载python-2.7.3： wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

2.解压

tar-zxvf Python-2.7.3.tgz

3.编译安装

./configure

make

make install

4.因为yum需要使用python-2.4，因此原python-2.4不能卸载

mv /usr/bin/python /usr/bin/python2.4

ln -s /usr/local/bin/python2.7 /usr/local/python

5.修改yum

vi /usr/bin/yum

将最上面的#!/usr/bin/python   改成#!/usr/bin/python2.4
