EC2上にPython実行環境を作った話

Python

大したことはしてない。

パッケージ更新とpip

sudo yum -y update
sudo easy_install pip

virtualenvとvirtualenvwrapper

あとはまあイアン先生の言うとおりに。
http://www.ianlewis.org/jp/virtualenv-pip-fabric

sudo pip install virtualenv
sudo pip install virtualenvwrapper
vim .bashrc

export WORKON_HOME=$HOME/.virtualenvs
source`which virtualenvwrapper.sh`
mkvirtualenv myenv

できたけど、Python2.7を使いたいぞ

Python2.7を入れる

cd /usr/local/src/
sudo wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz
sudo tar xzf  Python-2.7.3.tgz
./configure --with-threads --enable-shared --prefix=/usr/local/python-2.7.3

Cコンパイラが入ってなかった

sudo yum -y groupinstall 'Development tools'

もう一度

./configure --with-threads --enable-shared --prefix=/usr/local/python-2.7.3
make
sudo make install
sudo vim /etc/ld.so.conf.d/python2.7.conf
/usr/local/python-2.7.3/lib

[ec2-user@ip-255-255-255-255 Python-2.7.3]$ /usr/local/python-2.7.3/bin/python --version
Python 2.7.3

さっき作った環境のインタプリタを2.7.3にする

[ec2-user@ip-255-255-255-255 ~]$ virtualenv --python=/usr/local/python-2.7.3/bin/python ~/.virtualenvs/myenv/

Running virtualenv with interpreter /usr/local/python-2.7.3/bin/python
New python executable in /home/ec2-user/.virtualenvs/myenv/bin/python

Installing pip...............done.
[ec2-user@ip-255-255-255-255 ~]$ workon myenv
(myenv)[ec2-user@ip-255-255-255-255 ~]$ python --version
Python 2.7.3

できた。

botoでメール送ろうとしても送れない

(myenv)[ec2-user@ip-255-255-255-255 myenv]$ python ses_test.pyTraceback (most recent call last):

Pythonを入れたときにSSLが有効でなかった
openssl-develを入れてもっかいビルド

sudo yum install -y openssl openssl-devel
cd /usr/local/src/Python-2.7.3

ちゃんとlibを指すように修正

vim Modules/Setup

SSL=/usr
make clean
make
sudo make install

完了したので試す

workon myenv
cd ~/myenv/
python ses_test.py

はい。できましたー
