Apache & Python 500 Error

[Christian]

Hello,

i have an apache 1.3 server with python on debian. Python works fine but
the scripts wont´t work.

This easy script i want to do on apache:

#!/usr/bin/python
import os
os.getcwd()

in apache config i have done this:

<Directory /var/www/python>
AddHandler python-program .py
PythonHandler python
Order allow,deny
Allow from all
#PythonDebug On
</Directory>

the script is in this directory /var/www/python

but i get an 500 error everytime, with "every" script - why that - i´m
newbie - sorry for that

greetings from germany to newsgroup

What does the error log report ?

It is *possible* that you are getting an error 500 because your are
not emitting valid headers.

Try this instead :

#!/usr/bin/python

print 'Content-Type: text/plain\r'
print '\r'
import os
print os.getcwd()

I know what your problem is.

But first, check your apache error log. Then you will know what your error
is, too.

If you can't fix it after you try to fix the error in the log, or you
don't understand the log entry, post your program and all relevant log
entries. You did good posting your Apache configuration, but we also need
the log entries.

That said, fuzzyman is right, but keep this in mind for future help
requests.

But first, check your apache error log. Then you will know what your error
is, too.

Thanks for help, here is my error log:

You're confusing mod_python and cgi. And you're cgi isn't written
properly...

Try this to enable cgi for python files:

<Directory /var/www/python>
Options +ExecCGI
AddHandler cgi-script py
</Directory>

Don't forget to restart apache.

A proper cgi-file outputs a header with at least the content-type. A
header is followed by an empty line.

#!/usr/bin/env python

import os

print "Content-type: text/html"
print
print os.getcwd()

from mod_python import apache
^
SyntaxError: invalid syntax

----
My test script:
#!/usr/bin/python

print 'Content-Type: text/plain\r'
print '\r'
import os
print os.getcwd()

For the quote of the error message, I've taken the liberty of stripping
off the apache-added stuff off the front so you can read it better.

You should now be able to easily see that the error message and your shown
program don't mesh. That error appears to be from an earlier run.

Even so, I can tell you one thing: The error resulted from indenting your
"from mod_python import apache" call that you no longer have. Python uses
whitespace for structure, and just as you must indent the body of loops,
you must *not* extraneously indent other things (line continuations
don't count).

You'll need to post the correct error message after configuring Apache for
CGI as Peter showed, unless of course you figure out the problem.
