CentOSにPyPyをインストールする方法

Last updated at Posted at 2014-04-03

CentOSにPyPyをインストールしたときのメモ

CentOSにPyPyをインストールするためにいろいろ試行錯誤した結果、epelリポジトリから落として来れば十分だったのでメモを残しておきます。
ソース落としてきてコンパイルすればいいのですが、挑戦する型方は、メモリも時間もかなり消費するので覚悟しておきましょう。

要約

ログだらけで本文が長かったので必要なコマンドのみ列挙します。rpmパッケージをepelレポジトリからダウンロードしてくるだけです。

# yum --enablerepo=epel,rpmforge,remi search pypy
# yum --enablerepo=epel,rpmforge,remi info pypy
# yum --enablerepo=epel install pypy
# yum --enablerepo=epel install pypy-devel

試行錯誤

PyPyのページからDownloadする方法を以下の二通り試しました。

  1. PyPy - Downloadの2.2.1にあるLinux x86 binary (64bit, tar.bz2 built on Ubuntu 12.04.2 LTS)のバイナリを使用
  • ライブラリのバージョンが合わず断念しました
  1. PyPy - Downloadの2.2.1にあるSource (tar.bz2)のソースからコンパイル
  • メモリと時間のどちらも足らず断念しました

そこで、リポジトリからrpmパッケージを探すことにしました。

リポジトリからのインストール

CentOSのバージョンを確認

一応CentOSのバージョンを確認しておきます。

# cat /etc/redhat-release
CentOS release 6.5 (Final)

yum searchコマンドでPyPyを探す

--enablerepoオプションで、epel, rpmforge, remiリポジトリから探すように指定してyum searchしました。
そもそもリポジトリを追加していない場合は以下の記事を参考に追加してください。

# yum --enablerepo=epel,rpmforge,remi search pypy
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
 * base: ftp.iij.ad.jp
 * epel: ftp.jaist.ac.jp
 * extras: ftp.iij.ad.jp
 * remi: remi.kazukioishi.net
 * rpmforge: ftp.kddilabs.jp
 * updates: ftp.iij.ad.jp
=================================================================== N/S Matched: pypy ===================================================================
pypy-devel.i686 : Development tools for working with PyPy
pypy-devel.x86_64 : Development tools for working with PyPy
pypy-libs.x86_64 : Run-time libraries used by PyPy implementations of Python
pypy.x86_64 : Python implementation with a Just-In-Time compiler

  Name and summary matches only, use "search all" for everything.

yum infoコマンドでリポジトリやその他情報の確認

yum searchでは、どのリポジトリにPyPyがあるのかわからないので、yum infoで特定します。ついでにバージョンも確認しておきます。

# yum --enablerepo=epel,rpmforge,remi info pypy
Loaded plugins: fastestmirror, security
Loading mirror speeds from cached hostfile
 * base: ftp.iij.ad.jp
 * epel: ftp.jaist.ac.jp

yum installコマンドでインストール

ここまでの情報によると、epelリポジトリにpypyがあるので、--enablerepoにepelを指定してインストールします。

# yum --enablerepo=epel install pypy

Hello World

定番のHello Worldを実行します。

$ pypy
Python 2.7.3 (f66246c46ca30b26a5c73e4cc95dd6235c966b8f, Jul 30 2013, 09:27:06)

実行時間の比較。

CPythonとPyPyの実行時間の比較で使った関数で実行時間を比較します。

CPython

>>> rangelist = range(1,10000000)
>>> print reduce(lambda x, y: x + y, [testfunc1(rangelist) for temp in range(10)])/10
0:00:01.717502
>>> print reduce(lambda x, y: x + y, [testfunc2(rangelist) for temp in range(10)])/10
0:00:01.183652
>>> print reduce(lambda x, y: x + y, [testfunc3(rangelist) for temp in range(10)])/10
0:00:00.734407

PyPy

>>> rangelist = range(1,10000000)
>>> print reduce(lambda x, y: x + y, [testfunc1(rangelist) for temp in range(10)])/10
0:00:01.017655
>>> print reduce(lambda x, y: x + y, [testfunc2(rangelist) for temp in range(10)])/10
0:00:00.983054
>>> print reduce(lambda x, y: x + y, [testfunc3(rangelist) for temp in range(10)])/10
0:00:00.250842

PyPyでの実行時間はCPythonに比べてかなり短くなりました。
