CentOS环境 升级Python2.6.6至2.7.5

# python -V
Python 2.6.6

# wget http://python.org/ftp/python/2.7.5/Python-2.7.5.tgz[/code] 
3.解压源代码包

# tar xvf Python-2.7.5.tgz


4.进入解压目录并安装

# cd Python-2.7.5
# ./configure
# make all
# make install
# make clean
# make distclean


5.将系统默认的python设置为python2.7.5

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


6.检查Python版本

# python -V
Python 2.7.5


7.解决yum不能运行的问题

因为yum是依赖python2.6.6运行的，所以需要对yum做一些修改

# vim /usr/bin/yum


将第一行的#!/usr/bin/python修改为#!/usr/bin/python2.6
