Here's the Python script itself (test.py):
#!/Users/misha/AppData/Local/Programs/Python/Python35-32
print("Content-Type: text/html\n")
print("\n\n")
print("<h1>Test</h1>")
I have this in my Apache's configuration file httpd.conf:
<Directory "c:/Apache24/htdocs">
...
...
Options Indexes FollowSymLinks ExecCGI
...
...
</Directory>
AddHandler cgi-script .cgi .py
I restart Apache--everything else works just fine, but when I try to point to my Python test file in my browser, the server throws an Internal Server Error at me.
Here's my Apache's latest log file entries (I have edited them a little bit just for readability's sake):
(localhost-error.log)
[Thu Feb 11 14:24:39.357362 2016] [cgi:error] [pid 16872:tid 1028]

I don't even know what to do now.
It may be that Apache can't find the python interpreter. You should make sure the shebang in your file is correct. Test if you can run the file from a different folder.
Make sure you put shebang line in your code.
And check your script permissions. It should be executable.
To change file permission to executable in Linux: chmod +x filename.py
I don't know about windows.
I am developing a Flask application on CentOS 6.6 on Apache and Mysql. It is modified from The Flask Megatutorial. I am able to create normally the database, however when I try to access it from my browser I get 500 internal server error and this in the error_log file:
content type: text/html
<h1>Hello world!</h1>
[Sun May 03 18:39:53 2015] [error] [client my.ip.add.res] (104)Connection reset by peer: mod_fcgid: error reading data from FastCGI server
[Sun May 03 18:39:53 2015] [error] [client my.ip.add.res] Premature end of script headers: runp-mysql.fcgi
This is after I've edited down the runp-mysql.fcgi file to this:
#!flask/bin/python
#encoding=UTF-8
#import os
print "content type: text/html\n\n"
print ""
print "<h1>Hello world!</h1>"
Running this from the command line completes correctly.
My httpd.conf file ends with this:
FcgidIPCDir /tmp
AddHandler fcgid-script .fcgi
<VirtualHost *:80>
DocumentRoot /home/apps/my_app/app/static
Alias /static /home/apps/my_app/app/static
ScriptAlias / /home/apps/my_app/runp-mysql.fcgi/
</VirtualHost>
I was doing the same and a major issue was the permissions on the file. make sure it is executable and not read only.
Also I do not think that the runp-mysql.fcgi is where you want to do your printing. It should be in the views file. This is where you should have the connection to the your mysql database then start the wscgi server.
This is a very loose answer based on my actual problem and I am only uploading it in case someone else follows the same tutorial and also has a problem with deployment.
The gist of it is that under the python version I used (2.7) for deployment the flipflop module did not work and I had to use flup instead. For anyone getting the same error - try it, it might work.
I have deployed a Django 1.3.1 app on apache2 in my machine using mod_wsgi.I used to log some values in the app using python logging module and these were written to a mylog.txt file in the application base directory.However I deleted this file and commented out every log() call in my code.In the django standalone server the app runs without any problem.But when I start the app in apache,I get this apache log entry
[Sat Mar 31 09:34:40 2012] [error] [client 127.0.0.1] TemplateSyntaxError: Caught IOError while rendering: [Errno 13] Permission denied: '/home/me/dev/python/django/myapp/mylog.txt'
I cannot understand why this happens ,since I commented out every log related line in the code and even the variable which tells the logfile's name in settings.py
I tried clearing the cache..but even that didn't help
can someone help me figure this out?
The module details are as below
Apache/2.0.63 (Unix) DAV/2 mod_wsgi/3.3 Python/2.6.5 Server at 127.0.0.1 Port 80
what are the unix/linux permissions on your mylog.txt file?
ls -la /home/me/dev/python/django/myapp/mylog.txt should show the unix/linux perms. Can you paste the results of this command? (update it in your question above if possible)
Apache2 user on your system (depending on which linux distro of if you use Mac) are most likely 'www-data' or 'http'. You will need to make sure that mylog.txt has the correct unix/linux owner and the correct permissions mode so that apache2 can write into this log file.
I also met this problem in Webpy+Apache. And I changed the Apache logs directory owner to Apache user then the problem solved.
I am trying to execute a Python program using Apache. However, Apache will only serve the file and not actually execute it. The permissions on the file are r/w/x and it is in /var/www. I will post the contents of httpd.conf and the program code after. I also tried to running the python script as a .cgi file but that did not work as well. I have both the mod_python and mod_wsgi modules loaded into apache as well.
Python sample:
#!/usr/bin/python
# enable debugging
import cgitb
cgitb.enable()
print "Content-Type: text/plain\r\n\r\n"
print
print "Hello World!"
httpd.conf:
AddHandler cgi-script .cgi .pl
AddHandler python-program .py
I know its a small httpd.conf file but when I installed apache, there was nothing in the file. I should also mention that this is just so that I learn the basics of running python in apache. It is not meant for production.
Thanks for the help!
Edit
The OS I'm using is Ubuntu 10.04 and the version of apache is 2. I have python version 2.6 which is automatically used when #!/usr/bin/env python is invoked.
I am getting two main errors, the first is that the file is not being found even though the permissions of the file and folder are 777. The error from the log is
[Sun Feb 05 13:29:44 2012] [error] [client 192.168.1.3] File does not exist: /var/www/poit-0.1
This error is for a different python script that I did not write. What is weird is that the file shows up in the index of the folder when accessed from a browser window. However, when I navigate to the file, I get the above error.
The other error that I am getting is premature end of headers. The error is below:
[Sun Feb 05 12:10:19 2012] [error] (8)Exec format error: exec of '/var/www/pyth.py' failed
[Sun Feb 05 12:10:19 2012] [error] [client 192.168.1.3] Premature end of script headers: pyth.py
The first line of httpd.conf: AddHandler cgi-script .cgi .pl is irrelevant, since you're testing python scripts and not perl scripts. And you should define those directives within the location of your python script, and tell apache that it should execute cgi scripts in that location: Options +ExecCGI. This snippet would be a start:
<Directory /path/to/sample.py />
Options +ExecCGI
AddHandler cgi-script .py
</Directory>
Addendum 1:
As per my last comment, try this script. It should spit information about the cgi environment.
#!/usr/bin/python
import cgi
cgi.test()
Addendum 2:
I got your script to work with the above configuration. The problem is that script is written in python2. And the default interpreter apache is invoking to execute the script, is python3 (at least in my case, and chances are this would be the same for you too).
This is a python3 version of the hello world script:
#!/usr/bin/env python
# enable debugging
import cgitb
cgitb.enable()
print("Content-Type: text/plain;charset=utf-8")
print()
print("Hello World!")
Addendum 3:
For the first error, make sure the permission and the ownership of whatever directory and files you're attempting to deploy are properly set. And try adding those directives to httpd.conf:
Order allow,deny
Allow from all
Which will get you this:
<Directory /path/to/sample.py />
Options +ExecCGI
AddHandler cgi-script .py
Order allow,deny
Allow from all
</Directory>
For the second error, unless I am missing something, it looks like apache is invoking python 3 interpreter to execute your script. To rule out this possibility, you might try the following:
ls -al /usr/bin/python*
This will list the python interpreters available on your system. If you have more than one interpreter you'll get something similar to this output:
/usr/bin/python -> python3*
/usr/bin/python2.6*
/usr/bin/python3*
If not, it would be this output:
/usr/bin/python -> python2.6*
/usr/bin/python2.6*
To make sure, this is not the issue you're having, try with this modified sample script:
#!/usr/bin/python2.6
# enable debugging
import cgitb
cgitb.enable()
print "Content-Type: text/plain\r\n\r\n"
print
print "Hello World!"
You'll notice that I explicitly mentioned the version of the interpreter apache should invoke, which is ugly. But for the sake of testing, you can do it. Of course you should map #!/usr/bin/python2.6, to whatever binary you have on your server, and make sure you don't mix python 3 comtipable code with python 2 interpreter and vice versa.
Re: The Exec format error.
I've run in to this myself a couple of times before. I had the exact same (cryptic) error message.
I was developing Python (3) scripts to use via CGI in Notepad++ on my Windows machine, and then uploading them to my Linux server.
After much frustration, I discovered that this issue is related to line endings and you need to convert Windows line endings (\r\n) to UNIX line endings (\n).
In Notepad++ (6.1.5), you can achieve this by going to the Edit menu and selecting the EOL conversion option and then saving the file.

In my case, it was a trivial issue. I had to add this line:
#!/usr/bin/python3
to the top of every .py file I wanted to run.
Then, everything started working correctly.
I had the same symptom and my config looked okay compared to the answers above.
I found that my new install was not configured to load mod_cgi.so
Loading the required module looks a bit like this. If restarting the server will give you an error that the file was not found, figure out where the file is adjust the path accordingly.
LoadModule cgi_module modules/mod_cgi.so
I'm assuming you are using firefox. I read somewhere else on the 'net that it could be related to the firefox addons installed on a machine.
I was getting this error and I use firefox 20. Switched to Opera and I did not get any more errors and the python scripts seemed to execute just fine.
Edit: It was actually an eval() method call I had overlooked that had appended "(" and ")" to the results of the script that caused my failure. Once I removed them, it worked for me.
I noticed you did not post the javascript, html, or whatever it is you use to call the script in the first place. Perhaps you could post it for us? I did a direct copy/paste example from a blog site without looking at what I had copied. That was my error.
i'm trying to setup mod_wsgi to serve my django media files (i want to use this also in a developement env)
I followed this guide to correctly setup mod_wsgi.
This is my wsgi file ("django.wsgi")
import os, sys
path = '/home/smau/Workspace/Maynard/tothego_frontend/'
if path not in sys.path:
sys.path.append(path)
#Calculate the path based on the location of the WSGI script.
apache_configuration= os.path.dirname(__file__)
project = os.path.dirname(apache_configuration)
workspace = os.path.dirname(project)
sys.path.append(workspace)
os.environ['DJANGO_SETTINGS_MODULE'] = 'tothego_frontend.settings'
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
This is my conf file ("django.conf")
Alias /site_media/ "/home/smau/Workspace/Maynard/tothego_frontend/site_media/"
<Directory "/home/smau/Workspace/Maynard/tothego_frontend/site_media">

This is my "httpd.conf"

Everything seems to be like the guide, however, when i try to start/restart apache i get this error

The log doesn't seem (to me...) anyhow related to my problem. Why do i keep getting the "import" error? Did i give you enought information or do you need something else? I guess my pythonpath is correct:
You're supposed to include the configuration file (django.conf), not the WSGI script (django.wsgi).
