Python的安装与升级

下载Python
下载地址：http://www.python.org/ftp/python/3.2/Python-3.2.tar.bz2

安装Python
1 进入shell
2 解包：tar jxvf Python-3.2.tar.bz2
3 配置并安装：

  * cd Python3.2  
  * ./configure   
  * make && make install

修改默认的bash命令

• 到此我们已经安装完成了，但是我们进入shell后，发现python还是2.4.3版本，我们需要建立一个链接
  1 备份旧文件：mv /usr/bin/python /usr/bin/python-2.4.3.bak
  2 对python命令进行软链：ln -s /usr/local/bin/python3.2 /usr/bin/python
  3 检查python版本： python -V

配置yum

• 由于yum是基于python2.4的程序，所以我们需要重新配置yum程序
  1 vim /usr/bin/yum
  2 将其中的/usr/bin/python修改为#/usr/bin/python2.4
  3 wq
