Edit: OS is CentOS 5
I installed Python 2.5.5 and am trying to run some Python scripts via the browser.
Honestly, I have not worked with Python before. I attempted to load the python module into Apache, but it is already loaded and was skipped. I also confirmed that I can run python scripts from my command line if I make them executable.
However when I put "http://www.example.com/test.py" into my browser, it returns unparsed HTML as follows:
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>
</head><body>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete

<p>Please contact the server administrator,

<p>More information about this error may be available

<hr>
<address>Apache/2.2.3 (CentOS) Server at www.example.com Port 80</address>
</body></html>
I also have the following in my httpd.conf file.
AddHandler cgi-script .py
I am stumped as I do not know where to look from here. Does this ring a bell for anyone? Hopefully nothing too obvious that I am overlooking here...
Thank you in advance.
Edit: Found the following in the Apache error_log.
[Fri Feb 26 19:58:38 2010] [error] [client xxx.xxx.xxx.xxx] (13)Permission denied: exec of 'test.py' failed

I've only ever used mod_python for a Trac install and they provide fairly explicit instructions for their application.
However, while we were testing mod_python, I found this article helpful - you may too.
Structure : Thanks - reading up on this.From Grhm -
Apache will only execute files that are located in designated cgi-bin directories. Everything else is considered content that is passed to the viewer. Your root directory isn't, and shouldn't, be marked as such.
Use the
ScriptAlias <url-path> <directory>directive to set your cgi-bin directories. eg:ScriptAlias /cgi-bin/ /webroot/cgi-bin/. Copy your scripts there, then call http://www.example.com/cgi-bin/test.py. That should work for you.Structure : I configured the ScriptAlias as follows: ScriptAlias /cgi-bin/ /webroot/test/ Then I copied my script to that directory and called it from the browser, but the same error occured.From Christopher Karel -
Error 13 from apache indicates a filesystem permissions problem.
Is SElinux enabled? (what's the output of "ls -laZ test.py")I doubt it's a problem with ScriptAlias or AddHandler/ExecCGI (either of which will get apache to execute scripts) - since you're getting a 500 error and not the python source apache is clearly trying to execute the file.
Structure : -rw-r--r-- user user test.pyStructure : Above is the output. So far as I can tell, SElinux is installed but not enabled on this machine. (rental server, not exactly sure)quadruplebucky : Ah, chmod a+x that script. As an aside, cat /etc/sysconfig/selinux or sestatus will tell you SElinux status. If SElinux is not enabled then...Structure : SELINUX=disabled, also, I ran chmod a+x but to no avail. I am going to take a look Apache permissions, etc.quadruplebucky : Wait, I didn't notice this before... AddHandler python-program .py (not cgi-script) Also, try renaming your script - python has a builtin module "test".Structure : Thanks, I added the following three lines within adirective. AddHandler python-program .py, PythonHandler mytest, PythonDebug On... With these directives in my httpd.conf file I am able to run the test script. I am going to mark this as the answer given that it got me closest to the solution. Thank you for the assistance! From quadruplebucky
