cd ~
wget http://python.org/ftp/python/2.7.5/Python-2.7.5.tar.bz2
tar xvf Python-2.7.5.tar.bz2
cd Python-2.7.5
./configure --prefix=/usr/local
make && make altinstall

4,更改系统默认版本
mv /usr/bin/python /usr/bin/python.bak
ln -s /usr/local/bin/python2.7 /usr/bin/python

在完成了上面4步之后,如果有使用yum的话会发现出错,这是因为yum 依赖2.4.3而现在默认的 Python 版本是 2.7.3 。
vim /usr/bin/yum
将首行显示的 !#/usr/bin/python 修改为 !#/usr/bin/python2.4
