Python 2.6.6이 설치된 CentOS 6.2에서 Python 2.7.3을 설치하여 사용하기

1. "Development tools"를 설치한다.
   

   # yum groupinstall "Development tools"
   # yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel
   

2. "Python 2.7.3"을 설치한다(마지막 명령어가 "make install"이 아닌 "make altinstall"이다). 설치가 완료되면 쉘에서 "python2.7"과 "easy_install-2.7"을 사용할 수 있다.
   

   # wget http://python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
   # tar xf Python-2.7.3.tar.bz2
   # cd Python-2.7.3
   # ./configure --prefix=/usr/local
   # make
   # make altinstall

3. "Distribute"를 설치한다.
   

   # wget https://pypi.python.org/packages/source/d/distribute/distribute-0.6.49.tar.gz --no-check-certificate
   # tar xf distribute-0.6.49.tar.gz
   # cd distribute-0.6.49
   # python2.7 setup.py install

4. virtualenv 사용하여, 프로젝트 단위로 Python 버전 유지하기
   

   # easy_install-2.7 virtualenv
   # virtualenv-2.7 --distribute someproject
   New python executable in someproject/bin/python2.7
   Also creating executable in someproject/bin/python
   Installing distribute...................done.
   Installing pip................done.
   # source someproject/bin/activate
   (someproject)# python --version
