Using Alt install

Prerequisites

        
              yum groupinstall "Development tools"

        
              yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel

Python 2.10.5

Now the dependancies have been installed we can go ahead and get the python tar:

        
              wget https://www.python.org/ftp/python/2.7.10/Python-2.7.10.tgz

        
              tar -zxvf Python-2.7.10.tgz

        
              cd Python-2.7.10

The following command will install the Python interpreter in /usr/local/bin/python2.7

        
              ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib"

        
              make && make altinstall

Download and install Setuptools + pip

        
              wget https://bitbucket.org/pypa/setuptools/raw/bootstrap/ez_setup.py

        
              python2.7 ez_setup.py

        
              easy_install-2.7 pip

Python 2.7 should now be located:

        
              /usr/local/bin/python2.7
