Python2.7安裝

tar xvzf Python-2.7.8.tgz
cd Python-2.7.8
./configure --prefix=/usr/local
make && make install

拷貝Python標頭檔案

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

備份舊版本的python並連結新版本的python

cd /usr/bin
mv python python24
ln -s /usr/local/bin/python2.7 /usr/local/bin/python
rm -f /usr/bin/python 
cp /usr/local
 
/bin/python2.7 /usr/bin/python

* 修改yum指令碼，使其指向舊版本的python，已避免其無法執行*

vim /usr/bin/yum
    #!/usr/bin/python  -->  #!/usr/bin/python2.4
