服务器用的是Centos6.5，自带的Python是2.6，所以升级到2.7
1，下载Python2.7
wget -c https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz
2,解压
tar -zxvf Python-2.7.10.tgz
3,安装
#./configure
#make all #make install #make clean #make distclean#mv /usr/bin/python /usr/bin/python2.6.6
#ln -s /usr/local/bin/python2.7 /usr/bin/python
