1 安裝系統環境及及pypy
rpm -ivhhttp://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-6.noarch.rpm
rpm –import /etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-7
yum -y install nginxMySQL-libs mysql-develPython-setuptools
yum -y install pypy-libs pypy pypy-devel
2、安裝pip
wgethttps://bootstrap.pypa.io/ez_setup.py-O - | python
wgethttps://bootstrap.pypa.io/ez_setup.py-O - | pypy
wgethttps://pypi.python.org/packages/e7/a8/7556133689add8d1a54c0b14aeff0acb03c64707ce100ecd53934da1aa13/pip-8.1.2.tar.gz#md5=87083c0b9867963b29f7aba3613e8f4a
tar -zxcf pip-8.1.2.tar.gz
cd pip-8.1.2
python setup.py install
pypy setup.py install
3、使用pypy及模塊安裝：
執行： pypy pythonfile.py （跟python用法一樣）
模塊安裝： pypy -m pip install modulename
numpy安裝略有不同：
詳見：http://pypy.org/download.html#installing
到2016/06/07，numpy對pypy3的支持還沒有很好：
For now, NumPyPy does not work with PyPy3*, and is not complete. You may get warnings or NotImplemented errors. Please let us know if you get crashes or wrong results.

附：關於哪些模塊能在pypy裡正常安裝，哪些不能，官方給了列表，藍的表示可以，紅的表示失敗。
