This document discusses setting up NLTK on CentOS using Python 2.6. It recommends installing EPEL to access more recent Python packages. virtualenv is used to create a sandboxed Python environment and mod_wsgi is configured to run NLTK applications as WSGI scripts under Apache. A simple WSGI application is provided as an example.
![wsgi application
import nltk
from wsgiref import simple_server
def application(environ, start_response):
start_response('200 OK', [('Content-type', 'text/plain')])
return dir('nltk')
if __name__ == '__main__':
server = simple_server.make_server('', 5000, application)
server.serve_forever()](https://image.slidesharecdn.com/pythonsetup-110726080024-phpapp02/85/Python-setup-20-320.jpg)
