#96955 — Problem configuring apache to run python cgi on Ubuntu 14.04

Hello everybody,

I installed the LAMP stack on in Ubuntu, but I am having
problems configuring Apache to run python CGI scripts.

I ran:
sudo a2enmod cgi

I added to apache2.conf
<Directory /srv/www/yoursite/public_html>
        Options +ExecCGI
        AddHandler cgi-script .py
</Directory>

I created index.py:
#!/usr/bin/env python
# -*- coding: UTF-8 -*-# enable debugging
import cgitb

cgitb.enable()    
print("Content-Type: text/html;charset=utf-8")
print("Hello World!")

But it is still not working.

Can anybody help me out?

Thanks in advance.

"It isn't working" is about as useful as telling a mechanic "My car doesn't work" without giving details on what exactly is happening.

What exactly isn't working?  What error message are you getting?

The first thing I would check is to make sure the permissions on index.py are set to allow execution.  It is easy to forget to do that.

The error message that I am receiving in my browser is:
403: You don't have permission to access /index.py on this server.

The permissions of index.py is 755

Which Python are you running? If it's Python 3, change the shebang  
accordingly because "python" is assuming Python 2.

As I recall, you must have a blank line between the headers and the
content.

But that may or may not be your problem, as you haven't told us exactly
what is going wrong.

I am new to Ubuntu, is there a command so I can find out what the problem is?

The only error I can see right now is forbedden, you don't have permission to access /index.py on this server.

this is not a linux permissions error it is an error with the apache 
configuration you need to check roe acache config files
(you may also want to investigate WSGI as CGI is outdated)

Thank you very much. Can I write .py pages like in PHP or should I
use a framework like Django, Web2py or TurboGears?

I recommend using WSGI and a framework that uses it (my personal
preference is Flask, but the above will also work). Here are a couple
of simple sites:

https://github.com/Rosuav/Flask1
https://github.com/Rosuav/MinstrelHall

You can see them in operation here:

http://rosuav.com/1/
http://minstrelhall.com/

Note how URLs are defined in the code, rather than by having a bunch
of loose files (the way a PHP web site works). This makes it a lot
easier to group things logically, and utility lines like redirects
become very cheap. The maintenance burden is far lighter with this
kind of one-file arrangement.

These sites are really tiny, though, so if you have something a bit
bigger, you'll probably want to split things into multiple files. Good
news! You can do that, too - it's easy enough to split on any boundary
you find logical.
