install python 2.7 & virtualenv on CentOS 6

1. 安裝 gcc

# yum install gcc gcc-c++.x86_64 compat-gcc-34-c++.x86_64 openssl-devel.x86_64 zlib*.x86_64

2. Build Python-2.7 (downloads)

# wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tgz
# tar zxvf Python-2.7.8.tgz
# cd Python-2.7.8
# ./configure --enable-shared
# make
# make install

3. 載入動態資料庫

# touch /etc/ld.so.conf.d/python2.7.conf
# vim /etc/ld.so.conf.d/python2.7.conf
/usr/local/lib
# ldconfig

4. install virtualenv

# python-pip install virtualenv

5. 利用 virtualenv 建立 python 2.7 的開發環境 (因為 CentOS 6 預設的 python 版本為 2.6，預設的版本最好不要亂改)

# virtualenv fayeENV --python=python2.7
# source fayeENV/bin/activate
# python
Python 2.7.8 (default, Sep 17 2014, 15:35:06)
[GCC 4.4.7 20120313 (Red Hat 4.4.7-4)] on linux2

6. 離開 python 2.7 開發環境

# deactivate
