I recently configured a complete [Pylons](<http://www.pylonshq.com/>) \+ [PostgreSQL](<http://www.postgresql.org/>) environment for a customer. The operating system was (of course) [Ubuntu Hardy](<http://www.ubuntu.com/>). The system included the use of [Simpycity](<https://public.commandprompt.com/projects/simpycity>) and [WSGI](<http://www.wsgi.org/wsgi/>). Although I could never done it without the Pylons documentation, I found that it was unnecessary complicated for those who **just want to get it done**. These are the steps I took: 

**Install some dependencies:** The use of apt-get here is wonderful because I didn't even have apache2 installed yet.
    
    
    jd@hardy:~$ sudo apt-get install python-dev python-setuptools \
    python-psycopg2 libapache2-mod-wsgi
    jd@hardy:~$ sudo easy_install pylons 
    jd@hardy:~$ sudo easy_install genshi
    

**Set up a generic location for python egg cache:**
    
    
    jd@hardy:~$ sudo mkdir /home/pylons
    jd@hardy:~$ sudo chgrp www-data /home/pylons
    jd@hardy:~$ sudo chmod 770 /home/pylons
    

**Enable mod-wsgi**
    
    
    jd@hardy:~$ cd /etc/apache2/mods-enabled
    jd@hardy:/etc/apache2/mods-enabled$ sudo ln -sf ../mods-available/mod-wsgi.* .
    

**Initialize your HelloWorld app**
    
    
    jd@hardy:~$ mkdir www
    jd@hardy:~$ cd /var/www; ln -sf /home/jd/www jd
    jd@hardy:~$ cd jd
    jd@hardy:~$ paster create -t pylons helloworld
    Selected and implied templates:
      Pylons#pylons  Pylons application template
    
    Variables:
      egg:      helloworld
      package:  helloworld
      project:  helloworld
    Enter template_engine (mako/genshi/jinja/etc: Template language) ['mako']: genshi
    Enter sqlalchemy (True/False: Include SQLAlchemy 0.4 configuration) [False]: 
    Enter google_app_engine (True/False: Setup default appropriate for Google App Engine) [False]: 
    Creating template pylons
    Creating directory ./helloworld
      Recursing into +package+
    [...]
    

_Notice the choice of[genshi](<http://genshi.edgewall.com/>) as the template language._

**Configure your wsgi handler**
    
    
    jd@hardy:~$ mkdir ~/etc
    jd@hardy:~$ cd etc; joe helloworld.wsgi
    

**The helloworld.wsgi looks like this**
    
    
    import os, sys
    sys.path.append('/home/jd/www/helloworld')
    os.environ['PYTHON_EGG_CACHE'] = '/home/pylons'
    
    from paste.deploy import loadapp
    
    application = loadapp('config:/home/jd/www/helloworld/development.ini')
    

**Edit your 000-default file**
    
    
    jd@hardy:~$ sudo joe /etc/apache2/sites-enabled/000-default
    

**Add your WSGIScriptAlias**
    
    
    WSGIScriptAlias /jd/helloworld /home/jd/etc/helloworld.wsgi
    

**Restart Apache**
    
    
    jd@hardy:~$ sudo /etc/init.d/apache2 restart
    

You should be good to go!
