# Upgrade all package and Install/Upgrade Python 2.7 #
######################################################
## The version of CentOS I have only upgrades python to
#python -V => Python 2.4.3
# and node.js needs at least 2.6

####see: http://wiki.mediatemple.net/w/CentOS_5.5_(VE)_Server_Build_-_Django_1.3,_Python_2.7
#####BUT also see this for a more RPM dependent way of installing 2.7: http://www.chrisabernethy.com/installing-node-js-on-centos-redhat/

#sudo yum upgrade

 # You may want to also see this post about setting up a more flexible python environment using
 # virtualenv (similar to Ruby Version Manager that lets you install and switch between python versions)
 # http://jbowles.github.com/blog/2012/04/22/python/

#wget http://www.python.org/ftp/python/2.7/Python-2.7.tar.bz2
#tar -xvjf Python-2.7.tar.bz2
#cd Python-2.7
  ## NOTICE, I'M NOT PASSING ANY PARTICULAR OPTIONS, YOU MIGHT WANT TO SEE WHAT OPTIONS YOU MAY WANT/NEED
  ## I'M ONLY SETTING A INSTALL DIRECTORY SO THAT I CAN ALIAS MY PATHS LATER ON
#./configure --prefix=/usr/local/python2.7

 #Because of a mod_wsgi error that you will run into later, you should install the following dependencies before installing python:
# cd
# sudo yum install readline-devel #you should already have this
# sudo yum install gdbm-devel
# sudo yum install sqlite-devel

  ###TODO; find the right yum libraries for:
  #Python build finished, but the necessary bits to build these modules were not found:
  #_bsddb             _curses            _curses_panel   
  #_tkinter           bsddb185           bz2             
  #dl                 imageop            sunaudiodev 

  ## RESULT:
  # python build was successful but you wont be able to use the python modules that require external libraries mentioned in this message. Since we really just need Python-2.7 for install node.js I'll leave this for now.


 # Doubly ensure that you makefile is clean and up to date (though this isn't really necessary)
# cd Python-2.7
# make clean
# ./configure --prefix=/usr/local/python2.7

 #Assuming everything went well, build and install python 2.7
# sudo make
# sudo make install

#vim ~/.bashrc
#alias python='/usr/local/python2.7/bin/python'

  #You might need to source your bashrc
# source ~/.bashrc

  ##Then you should be able to do this
#python
#Python 2.7 (r27:82500, Jun 12 2012, 05:02:59)

 #See redis.io for configuration settings, but these should be sane enough updates to existing config:
