$yum instal gcc zlib-devel

2.安装openssl

$sudo yum install openssl-devel

3.下载Python2.7.3

$cd Python-2.7.3

6.安装Python2.7.3

$./configure  
$make all
$make install 
$make clean 
$make disclean

7.建立软连接

$mv /usr/bin/python /usr/bin/python2.6.6
$ln -s /usr/local/bin/python2.7 /usr/bin/python

8.查询Python

$python -V

9.解决yum不支持python2.7的问题

$vi /usr/bin/yum 

改成
#!/usr/bin/python2.6.6
