由于程序需要用到python，而centos自带的python 2.4版本太低了，而yum命令只支持python 2.4 ，所以就另外安装一个python 2.7

下载编译安装python 2.7

wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
tar zxvf Python-2.7.3.tgz
cd Python-2.7.3
./configure
make
make install

wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

tar zxvf Python-2.7.3.tgz

cd Python-2.7.3

./configure

make

make install

mv /usr/bin/python /usr/bin/python2.4
ln -s /usr/local/bin/python2.7 /usr/bin/python

1 2	mv /usr/bin/python /usr/bin/python2.4 ln -s /usr/local/bin/python2.7 /usr/bin/python

因为yum依赖python2.4,所以要修改一下yum

vi /usr/bin/yum

1	vi /usr/bin/yum

将文件开始的

#!/usr/bin/python

1	#!/usr/bin/python

改成

#!/usr/bin/python2.4

1	#!/usr/bin/python2.4

这样就可以继续使用yum命令了。
