1> 安装Python2.7

wget http://www.python.org/ftp/python/2.7.10/Python-2.7.10.tar.xz

unxz Python-2.7.10.tar.xz

tar -zxvf Python-2.7.10.tar.xz

cd Python-2.7.10

./configure --enable-shared --enable-loadable-sqlite-extensions --with-zlib

vi ./Modules/Setup

搜索#zlib zlibmodule.c -I$(prefix)/include -L$(exec_prefix)/lib -lz，并去掉注释

make && make install
安装好后，备份Python2.6，并对Python2.7创建软连接

mv /usr/bin/python /usr/bin/python2.6.6
ln -s /usr/local/bin/python2.7 /usr/bin/python

现在执行python，可能会有以下报错：

error while loading shared libraries: libpython2.7.so.1.0: cannot open shared object file: No such file or directory
在vi /etc/ld.so.conf文件最后添加一行/usr/local/lib;
/sbin/ldconfig
/sbin/ldconfig -v

然后再执行python或者python -v

注意：现在执行yum命令可能会报错，编辑/usr/bin/yum，将第一行的#!/usr/bin/python修改成#!/usr/bin/python2.6.6
