获取Python2.7版本的源码包

Python2.7安装

tar xvzf Python-2.7.8.tgzcd Python-2.7.8./configure --prefix=/usr/localmake && make install

拷贝Python头文件

cd /usr/local/include/python2.7cp -a ./* /usr/local/include/

备份旧版本的python并链接新版本的python

cd /usr/binmv python python24ln -s /usr/local/bin/python2.7 /usr/local/bin/pythonrm -f /usr/bin/python cp /usr/local/bin/python2.7 /usr/bin/python

* 修改yum脚本，使其指向旧版本的python，已避免其无法运行*

 

vim /usr/bin/yum    #!/usr/bin/python  -->  #!/usr/bin/python2.6
