3.下载并解压最新Python 2.7的源代码
wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tar.xz
tar xf Python-2.7.10.tar.xz
4.编译与安装Python
cd Python-2.7.10
./configure –prefix=/usr/local
make && make install
make clean
make distclean
5.将系统python命令指向Python 2.7
mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python
6.将yum需要执行的python指定为2.6.6
vi /usr/bin/yum
