二、查看已安装python版本

[[email protected] ~]# rpm -qa|grep python
python-2.6.6-36.el6.x86_64
libxml2-python-2.7.6-8.el6_3.4.x86_64

三、下载编译安装python2.7.5版本源码包

[[email protected] ~]# cd /usr/local/src
[[email protected] ~]# wget https://www.python.org/ftp/python/2.7.5/Python-2.7.5.tgz
[[email protected] ~]# tar xvf Python-2.7.5.tgz
[[email protected] ~]# cd Python-2.7.5
[[email protected] ~]# ./configure
[[email protected] ~]# make all
[[email protected] ~]# make install
[[email protected] ~]# make clean
[[email protected] ~]# make distclean

 

四、将系统默认的python版本设置为2.7.5

[[email protected] ~]# rm /usr/bin/python
[[email protected] ~]# ln -s /usr/local/bin/python2.7 /usr/bin/python

 

五、检查升级后的python版本
