Full Version: How To Allow Cgi
Linuxhelp > Support > Technical Support
Hi. I have already found many pages with "sure" informations how to solve my problem, but the problem persists. I'm trying to enable all users on my server to make and use their own CGI-BIN scripts. I know, it shouldn't be so hard, but I'm trying it for 3 days now without success. :-) It took me only 2 hours to understand and successfully make my own kernell, so I'm really fed up with this little file named httpd.conf...
I'm able to execute scripts only by using scriptalias, but this is not what I want. I want that users can make their own scripts in their home/html directory and subdirectories, and it should be accessible this way: for example...

I'm adding whole configuration file httpd.conf in current not working state. I haven't (or I don't know about) any other configuration files for apache. I have RedHat 9.0, using RPM version of apache (httpd-2.0.40-21.9)

This message I get everytime I try to run any script:

Server error!
The server encountered an internal error and was unable to complete your request.
Error message:
Premature end of script headers: index.cgi
If you think this is a server error, please contact the webmaster
Error 500

there is nothing interresting in /var/log/httpd/access_log nor in error_log

Does anyone here know how to make it work?
(sorry for my english)
you have to add a cgi-bin directory in each users directory
and add that directory in the httpd.conf file

the same as /home/*/html is listed in there
and that should allow each user cg-bin access
Thank you for answer.
I've added directories cgi-bin into /home/*/html and these lines into file httpd.conf:

<Directory /home/*/html/cgi-bin>
AllowOverride none
Options +ExecCGI
Order allow,deny
Allow from all

but the problem still persists. Still error 500, premature script headers. What access rights should have the scripts, and directories? I have tried to change users using chown (root, user, apache) and access rights (read all, execute all) for scripts (-rwxrwxr-x) and the same for directories (drwxr-xr-x), without success. I'm really fed up with this. sad.gif I newer thought I could say this, but it looks, that Windows configuration is much easier... dry.gif
you might have to add a scriptalias for that directory in your httpd.conf file

look at the one already there for cgi-bin access

and then you should be able to copy that and just rename the directory listing
that it points to for the directory information and the scriptalias part
and use that for your /home/*/html/cgi-bin
I didn't understand completely - I've changed scriptalias to this:

ScriptAlias /cgi-bin/ "/home/*/html/cgi-bin/"

<IfModule mod_cgid.c>
Scriptsock run/httpd.cgid

<Directory "/home/*/html/cgi-bin">
AllowOverride None
Options +ExecCGI
Order allow,deny
Allow from all

but still the same error. Is it possible to use '*' in Scriptalias? I've read manual, and it looks that it is not...

you script alias line should look something like this :

ScriptAlias /cgi-bin/ "/home/www/test/html/cgi-bin/"

you should change "/home/www/test/html/" to the folder you will use

I am not sure..if it will work with cgi scripts..But same sort of thing i have done in PHP...

If you check out file httpd.conf( biggrin.gif i know you are fed up)

Then you will find that each user can create a directory called
public_html in his home directory and that can be used as document root for apache..So you will acess this file

with following url in your browser..

Just you have to enable..this support in the file...httpd.conf and restart apache.
Also..since that directory should be readable to all..
$ chmod 755 public_html

this will help i guess..
Thanks for answers.
Like I said before, I need that cgi-bin scripts can execute in many user directories, not only in one, like /var/www/html/cgi-bin. I need scriptalias to look similar to this: /cgi-bin/ "/home/*/html/cgi-bin" but this one doesn't work for me.

I know about public_html, I've already changed it to html only. This parts of httpd.conf are quite easy, and I understand it very well. But I don't understand to scriptalias and to setting directories for web access - or I do, but it doesn't work the way, I need. dry.gif
