2.安裝 zlib-devel######否則安裝setuptools的時候會報錯
yum -y install zlib-devel sqlite-devel # django開發時用
./configure --prefix=/export/servers/python
make && make install
3.ln -s /export/servers/python/bin/python /usr/local/sbin/python
4. vim /usr/bin/yum ,修改yum的運行版本爲：/usr/bin/python2.6 ,否則yum無法啓用

python setup.py build
python setup.py install
