problems running script [Archive]

View Full Version : problems running script

I'm trying to get a script to run but it refuses to cooperate.

I have the public_html directory chmod 777. The file is chmod 755 and owned by the user. I have an .htaccess file with Options +ExecCGI so I can run outside of the cgi-bin.

If I run it via ssh as "perl filename.cgi" it outputs the correct html. But when I view it in my browser I get a 500 internal server error. The error log only contains a "Premature end of script headers".

Any ideas what could be causing this? It's frustrating. :(

Hey,

Did you have a content type set in your script? Like so:

print "Content-type: text/html\n\n";

David

james99

Yup.

[root@server2 www]# perl log-in-page.cgi
Content-type: text/html

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>

...

Is that a good thing or a bad thing?

Thats a good thing.

I see when you run it on the command line, you call perl specifically. Does the first line of the script look exactly like this?

#!/usr/bin/perl

If so, see if the program will work from the command line with just "./filename.cgi" without the perl call.

make sure the user can "run" it. If you create the script as root, you must "chown" it.

james99

07-24-2004, 10:56 AM

GNU nano 1.2.1 File: log-in-page.cgi

#!/usr/bin/perl

-rwxr-xr-x 1 nervousn nervousn 6326 Dec 22 2003 log-in-page.cgi

[root@server2 www]# ./log-in-page.cgi
Content-type: text/html

Let me switch to the user and try it.
[nervousn@server2 public_html]$ ./log-in-page.cgi
Content-type: text/html

-rwxr-xr-x 1 nervousn nervousn 6326 Dec 22 2003 log-in-page.cgi

GNU nano 1.2.1 File: log-in-page.cgi

#!/usr/bin/perl

I'm totally stumped.

Or you can try to run a very simple script just output a string 'hello world!', to make sure it can run CGI script actually!

james99

07-24-2004, 11:06 AM

[quote][root@server2 www]# ./cgi-test.cgi
Hello World[/qute]

Yet, via http it gives internal server error.

Hmm. Wait! I think I might've figured it out.

I'm still in the process of moving files over to the DA server (previously used cPanel), so I haven't changed the DNS yet.

I've been accessing the site via http://hostname/~user/

Could that be causing the problem?

If so, any suggestion for how I can finish tweaking the scripts without changing the DNS just yet?

thuskey

07-24-2004, 10:31 PM

http://ipaddress/~user maybe?

james99

07-25-2004, 08:35 AM

Something is wrong here because I gave the account a dedicated IP, and accessing it at http://IP/log-in-page.cgi gives a 500 error as well.

Ugh. Any more ideas?

It needs to be in the CGI-BIN. I had similar problems, and using the CGI-BIN was the only solution.

Scripts do not necessarily have to be in cgi-bin.

They can be in any directory as long as the directory also contains a .htaccess file with the following two lines:

Options +ExecCGI
AddHandler cgi-script .cgi .pl

Jeff

james99

07-25-2004, 10:27 AM

OK, I changed my .htaccess and it still gives the error.

I moved cgi-test.cgi to the cgi-bin which consists of just:

#!/usr/bin/perl

print "Hello World\n"

and that script when accessed via http in the cgi-bin gives the error.

:(

jlasman

07-25-2004, 11:00 AM

Will you...

Show us the "ls -al" output for the cgi-bin directory holding the test.cgi.

Give us the real web-path to the file so we can test it.

:confused:

Do any other cgi programs for this site work?

Do any other cgi programs on the server work?

Nope, no CGI works for this site. PHP does, not that that matters since the majority of the site is in Perl and slowly being ported into PHP.

Um, not sure about server-wide as this is the only account on the server. Want me to create another and give it a whirl?

Why is the directory world writable?

The "." entry should be chmod 755, not 777.

First try making the cgi-bin directory chmod 755 and see if that makes a difference.

If that doesn't work, take a look at the apache error log for the site.

changed to chmod 755, but it still gives the error.

Or you may need to create another account and do the same things to test it out.

:)

james99

07-26-2004, 07:41 PM

OK, I created another account with:

username: testuser
domain: nervousness.us

Then I created a file using nano of just:

#!/usr/bin/perl

print "Hello World\n"

I did chmod 755.

Via SSH:

[testuser@server2 cgi-bin]$ ls -al
total 16
drwxr-xr-x 2 testuser testuser 4096 Jul 27 03:40 .
drwxr-x--- 25 testuser apache 4096 Jul 27 03:37 ..
-rw-r--r-- 1 testuser testuser 17 Jul 27 03:35 .htaccess
-rwxr-xr-x 1 testuser testuser 39 Jul 27 03:40 test.cgi
[testuser@server2 cgi-bin]$ ./test.cgi
Hello World
[testuser@server2 cgi-bin]$

But, it still gives 500 internal server error via http.

See it @ http://nervousness.us/cgi-bin/test.cgi

07-26-2004, 09:37 PM

Well, first off you're going to need to print out the text/html header, i.e.:#!/usr/bin/perl

print "Content-Type: text/html\n\nHello World\n"Phi1.

James, I'm headed to a Avici certification class at the moment and don't have enough spare time to troubleshoot ths now, but what if I were to call you this evening, around 7pm central time? Would you have time to work this issue then? Just PM me your number, if it is in the US, or let me know a good time to catch you on skype, and I'll give you a call.

07-30-2004, 11:45 AM

OK, an update!

I switched the DNS to start resolving to the new DA server, recreated the account, etc.

CGI now works in the cgi-bin (example (http://nervousness.org/cgi-bin/cgi-test.cgi)), but not outside of it (example (http://nervousness.org/cgi-test.cgi)),which it needs to for this site.

Hey,

Just curious what happens if you change the public_html to be nervousn:nervousn?

David

james99

07-30-2004, 02:04 PM

That fixed it! :D Thanks so much!

Is public_html supposed to be created user.apache? It's created that way every time for me. Not that it really matters because there's only going to be one account on this server - not web hosting, just a personal site and DA is worth the $10 a month for making updates and adding emails easier.

Thank you!

Hey,

Glad it works...

I'm not really sure about public_html...

Looking over the stuff you posted I saw this:

[2004-07-30 19:34:05]: error: target uid/gid (501/501) mismatch with directory (501/103) or program (0/0)

And took a guess from there... (^:

Earliest versions of DA created the public_html directory as user:user

Current versions of DA create the public_html directory as user:apache

Since DA is dynamically updated, you may have both settings on your server depending on when the sites were created.

This is definitely an issue to be brought to the attention of DA staff, as I don't recall why it was changed.

I'll bring the post to their attention.

I'm sure it was changed because the default user is apache and the default group is apache. Without the directory group being set to apache, you can not use http://x.x.x.x/~user/
