Executing Python cgi files in Apache on Windows

I am trying to run a very simple "Hello World" program with Apache. However, Apache returns a 500 Internal Server Error when it tries to execute my python file. I've read several similar topics on here and tried the suggestions, no luck. Things I have tried:

  1. Including the AddHandler with .py files to the .conf file
  2. Adding ExecCGI to the "Options Indexes" line in the .conf.
  3. Making sure the first thing output is ""Content-Type:text/html" with 2 end of line characters.
  4. Adding a shebang line to the top of the python file to direct to the Python interpreter. I'm not sure if I'm doing this part right.
  5. Restarting Apache

The tools I am using include:

  • Windows 7
  • Python 3.5
  • Apache 2.4

My code: The HTML File (in the htdocs folder in the Apache folder):

<form action="/cgi-bin/hello_get.py" method="post">
First Name: <input type="text" name="first_name">  <br />

Last Name: <input type="text" name="last_name" />
<input type="submit" value="Submit" />
</form>

The python file (in the cgi-bin folder):

# Note that I tried this without the C:/ also
#!C:/Users/MyName/workspace/Flask/flask/Scripts

# Import modules for CGI handling
import cgi, cgitb

# Create instance of FieldStorage
form = cgi.FieldStorage()

# Get data from fields
first_name = form.getvalue('first_name')
last_name  = form.getvalue('last_name')

print("Content-Type:text/html\r\n\r\n")
print("<html>")
print("<head>")
print("<title>Hello - Second CGI Program</title>")
print("</head>")
print("<body>")
print("<h2>Hello %s %s</h2>" % (first_name, last_name))
print("</body>")
print("</html>")

I know Flask but I am required to use Apache :/ – Village
then use Apache+mod_wsgi + Gunicorn+Flask (or maybe Apache+mod_wsgi+Flask) – furas

I figured it out.

In my shebang line, instead of:

#!C:/Users/MyName/workspace/Flask/flask/Scripts

I should have:

#!C:/Users/MyName/workspace/Flask/flask/Scripts/python.exe

I thought my shebang should have a path to where the python interpreter lives, I didn't realize I needed the actual full path of the interpreter.

It is working now.

So to recap, if you are having this issue after following these instructions: http://editrocket.com/articles/python_apache_windows.html Make sure that if you are using Windows the path is the full absolute path from the C:/ drive to the python.exe executable.
