with your webserver: 7 Tips for Newbies
you've just downloaded a cool CGI program and are trying to get
it working on your Linux Webserver, or simply having trouble with
one you wrote. Here are things we've noticed tend to resolve
almost all issues we've personally encountered.
There's a Readme file Read It!
Carefully and thoroughly read the README that came with your CGI
program. Lets face it, you will NOT be able to setup most
cgi programs on your site unless you can read this patiently!
2. Edit Carefully Using these Tips.
Carefully edit the .cgi file and make sure not to forget
to run the chmod command as described in README.
When editing be very careful if you use the PICO editor since it
does not handle long lines properly and often truncates lines
creating errors! We recommend using a different text editor if
you're doing major edits. Also, Do NOT change the first line
#!/usr/bin/perl unless you know why you're doing it!
3. Fix any bugs that cause .cgi file to fail.
On more than one occasion I have seen CGI files with
some bug or other. One example common bug is that somewhere there
is a missing close parenthesis. Just make sure
whenever there's an open ( there's also a close ) okay!
4. Test the cgi perl script by
running command: perl search.cgi
5. Know your web directory location!
Often when the documentation refers to your web root
directory or your www directory they actually mean the /home/httpd/
directory which is considered your web root directory. You can
always use the locate httpd command to find out where on
your particular web server this is.
6. Using tar files?
IF you also happen to be using a TAR file just note that
the tar file may be stupid. Often a tar file when untarred is
suppose to create a specific directory under your /home/httpd/cgi-bin
but does not do so. Instead, you may want to create the correct
directory yourself, otherwise you need to be careful to change
the directories in the refering .cgi file and form.txt to include
the appropriate directory. Does this 6th tip not make any sense
to you? Please ignore it if you're not dealing with a tar file!
7. Always check the error_log for info if the .cgi
is not working properly.Your log files for your web server would
be located under the httpd directory so try to run locate httpd
and see if something like /httpd/logs shows up.
After placing the appropriate files in the right directories you
should be able to insert the form.txt directly into your .html
page and see how it works.
Often CGIs taken
off the web tend to be simple installations, so if youre
really having problems, stop and check for simple things!
