# Python for System Administrators

The course requires:
* python 2.7+ (see notes on python3)
* easy_install or pip as package manager
* ipython / jupyter
* see requirements.txt

Use the following instructions to setup your environment
and try the python crash course reading and typing on 
you shiny ipython console the exercises contained in 

    #python-basic

NB Python3.0 is not the default python version on many distributions so it's still not time
   to switch to it for system administration tasks. Moreover you may not find
   precompiled packages. Anyway once you have a compiler and the needed headers, pip should build 
   everything you need (at least to me it worked). 


## Generic Python
Just

    #pip install -r requirements.txt


## Docker via Compose (downloads a 1GB image)
Just run:

    #docker-compose up


## Linux Ubuntu
Just run

    apt-get install ipython python-pip python-psutil python-nose python-scipy python-numpy python-matplotlib tree dstat


## Linux Red Hat / Centos / Fedora
Install the EPEL repository

    rpm -ivh http://ftp.tu-chemnitz.de/pub/linux/fedora-epel/6/i386/epel-release-6-8.noarch.rpm

Then install ipython and python-pip

    yum install ipython python-pip python-psutil tree dstat


## Mac OS and Windows (easy way)

Download python from [Continuum](http://continuum.io/downloads) and
install following the [provided instructions](http://docs.continuum.io/anaconda/install.html)

Then from the terminal:

    #conda update conda
    #conda update ipython ipython-notebook ipython-qtconsole \
        readline psutil matplotlib scipy numpy nose



## Windows (hard way)
Install Python from python.org http://www.python.org/getit/windows/
Install pip following the instructions provided here https://pip.pypa.io/en/latest/installing.html

My python directory is python27: replace it with your python installation path.
From the console, install pyreadline, psutil, ipython, ansible and pyparsing

    c:\python27\Scripts\easy_install pyreadline \
        ipython nose pyparsing pyzmq \
        markupsafe tornado jsonschema psutil ansible


To install numpy scipy matplotlib just download and install the binaries for your windows version in the given order from 

    http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy
    http://www.lfd.uci.edu/~gohlke/pythonlibs/#scipy
    http://www.lfd.uci.edu/~gohlke/pythonlibs/#six
    http://www.lfd.uci.edu/~gohlke/pythonlibs/#dateutil
    http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib

Test your ipython installation running it
    c:\python27\Scripts\ipython

Test if the libraries are fine 
- download the test_course_environment.py from github
- running ipython *after* you've installed all of them
- run the following command
  c:\python27\Scripts\nosetests test_prerequisites.py
