centOS升级python2.6至2.7

1.安装

#yum install -y gcc#wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz#tar -xvf Python-2.7.9.tar#cd Python-2.7.9#./configure#make#make install

2.安装并更改系统默认的python

#cd /usr/local/bin/python2.7 -V  #mv /usr/bin/python  /usr/bin/python.bak#ln -s /usr/local/bin/python2.7 /usr/bin/python

3.修改yum配置

#vi /usr/bin/yum

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

4.修改ibus配置

vi /usr/bin/ibus-setup  vi/usr/libexec/ibus-ui-gtk

找到 exec python 那一行，把exec python 改为 exec python2.6
