CentOS6 编译安装pypy
据说pypy性能要比python高很多，刚好手上的项目目前存在很大性能问题，就体验一下pypy看看
记录下安装过程
下载源码，安装依赖包
wget https://bitbucket.org/pypy/pypy/downloads/pypy2-v5.6.0-src.tar.bz2
yum install gcc make libffi-devel pkgconfig zlib-devel bzip2-devel \
lib-sqlite3-devel ncurses-devel expat-devel openssl-devel tk-devel \
gdbm-devel \
xz-devel # For lzma on PyPy3.解压源码包，开始编译
tar jxvf pypy2-v5.6.0-src.tar.bz2
cd pypy2-v5.6.0-src/pypy/goal
python2.7 ../../rpython/bin/rpython -Ojit targetpypystandalone机器还没有安装pypy就只能用python来跑了，不过这个就是慢 官方文档 有说明
漫长等待后出现如下内容，则会在当前的编译目录生成一个pypy－c的文件
