I am trying to run a simple cgi script after configuring my server.
My script looks like this:
print "Content-type: text/html"
print
print "<html><head><title>CGI</title></head>"
print "<body>"
print "hello cgi"
print "</body>"
print "</html>"
When I go to my scripts url http://127.0.0.1/~flybywire/cgi-bin/main.py I get:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
And in error.log I get the following:
[error] (8)Exec format error: exec of '/home/flybywire/www/cgi-bin/main.py' failed
[error] [client 127.0.0.1] Premature end of script headers: main.py
Other info: Apache/2.2.8 (Ubuntu) DAV/2 SVN/1.4.6 Server at 127.0.0.1 Port 80
You might need a #!/usr/bin/python at the top of your script to tell Apache to use Python to execute it. At least, I did that and it worked for me :-) .
Also, save the file (if this is a Linux server) with Unix line endings. You did make it executable using chmod +x didn't you?
You can use #!/usr/bin/env python to cover the current running Python version if you're running in various environments (hence the env part).
It looks like Apache has trouble executing it. Typically for a unix script you also need to specify the interpreter at the top of the script.
Try adding this to the top:
#!/usr/bin/python
Putting
#!/usr/bin/env python
on the top of the script works fine. I put it on top, but Netbeans was putting extra code (import commands) by itself on the top of the page which drove me crazy :(
Maybe your problem is that new python version needs parentheses ( ).
So your:
print "<body>"
Now should to be:
print ("<body>")
remove the 2nd line in your program (print) I tried it on my apache server (mac os x) it works fine. don't forget to chmod 755 and reboot with sudo apachectl restart This is for python 2.7
print "Content-type: text/html"
print "<html><head><title>CGI</title></head>"
print "<body>"
print "hello cgi"
print "</body>"
print "</html>"
