CentOS 6自带的python是2.6的，下面记录下CentOS6源码安装python 3.5的过程
#wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tgz
#tar xf Python-3.5.2.tgz
#cd Python-3.5.2
#./configure --prefix=/usr/local/python3 --enable-shared --enable-loadable-sqlite-extensions
#make
#make install
#echo /usr/local/python3/lib >> /etc/ld.so.conf
#ldconfig
#ln -s /usr/local/python3/bin/python3.5 /usr/bin/
