linux更新python

linux下原来安装的python是2.4,现在需升级至2.7.

1.首先下载2.7的压缩包：

wgethttp://www.python.org/ftp/python/2.7.1/Python-2.7.1.tgz

2.解压安装：

$tar-xvfPython-2.7.1.tar

$mvPython-2.7.1/usr/local/

$cdPython-2.7.1

$./configure

$make

$makeinstall

3.更改软链接：

ln-s/usr/local/Python-2.7.1/python./python

4.测试：

输入python，显示如下：

Python2.7.1(r271:86832,Feb242011,09:20:11)

[GCC4.1.220080704(RedHat4.1.2-46)]onlinux2
