centos6.5 升级python2.6到python2.7

#tar -xf Python-2.7.9.tar.xz

#cd Python-2.7.9

#mkdir /usr/local/python27

#./configure --prefix=/usr/local/python27

#make

#make install

如果此时出现找不到所依赖的模块可先不必管它

#mkdir /usr/local/python26

#mv /usr/bin/python /usr/local/python26

将原来的python文件备份到python26文件夹下

#ln -s /usr/local/python27/bin/python2.7 /usr/bin/python

将编译后bin文件夹下的python2.7 链接到 /usr/bin/python位置上

# python –v

查看python版本，此时已升级到2.7

解决升级后的centos无法使用yum

#vim /usr/bin/yum

把最头部的：

#!/usr/bin/python

改成：

#!/usr/bin/python2.6
