problems with an python cgi script in apache

**leke** · 04-18-2010 03:51 AM

Hi, I have a python cgi script (called image.cgi) which works fine when I run it from the terminal as a py script, but when I try and run it from my apache web directory, I get the following error in the apache log.

[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1] Traceback (most recent call last):
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1] File "/var/www/public_html/grooveshark/image.cgi", line 19, in <module>
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1]
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1] text_file = open("trackDB.txt", "w") # create the DB
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1]
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1] :
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1] [Errno 13] Permission denied: 'trackDB.txt'
[Sun Apr 18 11:30:39 2010] [error] [client 127.0.0.1]

The error seems to say that the access to trackDB.txt is denied, but I have the file access at 755 (trackDB.txt will just have some text written to it).
A regular python cgi script seems to work for example, a simplified version of my code with error catching...

Code:

#!/usr/bin/env python

import Image, ImageDraw, ImageFont, random, feedparser
import cgi

print "Content-type: text/html"
print
	
try:	
	
    print '''
	<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
	<html>
	<head>
	<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
	<script language = "JavaScript" src="grooveshark.js"></script>
	<title>GrooveShark sig</title>
	</head>
	<body>
	'''
	
    print '<a href="http://google.com"><img src="test.png"></a><p>Hello</p>'
    print "world"
    
    print '''
	</body>
	</html>
	'''

except:
    import cgi
    cgi.print_exception()

Works just fine.

Does anyone have any ideas what is happening. BTW, the output in the browser is just a blank page.

Thanks.

Check the owner (uid) of the file to make sure that it is the effective uid of what is running the script since -rwx- permission is given in that case. Write permission is not given to the group or others! Resolve that conflict.

Errno 13 probably refers to a standard Unix error code (EPERM, I am guessing).

Perhaps a google search helps too? I tried this:
