tar zxvf Python-2.7.9.tgz

./configure

make install

ln -s /usr/local/bin/python2.7 usr/bin/

修改yum配置文件以保证yum可用

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-libs-2.0.2-1.el6.x86_64.rpm

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-2.0.2-1.el6.x86_64.rpm

wget http://dl.fedoraproject.org/pub/epel/6/x86_64/pypy-devel-2.0.2-1.el6.x86_64.rpm

注意安装顺序先安装libs 再安装pypy 最后安装devel

经测试 pypy的效率要比cpython高大约三到四倍
