Re: Received 404 not found error on existing CGI script (Apache Users)

Hello,

Thanks for your reply. I solved the not being able to run a Perl CGI script issue. I now have several of my old Perl CGI scripts up and running.

Now one of my other CGI scripts is failing badly. The mysql error log does not show anything useful. All I see on my screen is a '500 internal server error'. I checked the syntax of my perl script and it is ok.

Your message stated that setting "my log file level to debug" was a good debugging idea. I have been trying to figure out how to accomplish this task with no success. Which config file do I need to change and what specific change do I need to make to the config file ?

Thanks/

Try setting your log file level to debug, you will get far more information. Also at the end of the 'log format' code in your configuration file (easy double check by command 'httpd -V' which will double check your conf file) add '%L' which when added to both access_log file formats AND error_log formats will give matches between the two easily found with the 'grep' command 'grep "[long-scrambled-unique-characters-for-that-particular-error] '*_log' . Make sure you first are in the log directory.

Another helpful tip… your apache comes with it’s VERY OWN manual pages which when enabled in your 'includes' section of your config file, will allow you to access MUCH quicker than going online, where you will find everything you need to know.

my system is an ubuntu 20.04 lts laptop.

I successfully installed apache2. I verified the installation by visiting http://localhost:80

Now I am having problems trying to run a Perl CGI script which I had running under Windows 10 on Apache 2.4

I modified the sites-enabled/000-default.conf file by removing the '#' from the start of the "Include conf-available/serve-cgi-bin.conf" line. I then created the /usr/lib/cgi-bin directory. I next put a small Perl CGI script named "printenv.cgi" under /usr/lib/cgi-bin. I then restarted the apache2 server. When I attempted to run my newly created CGI script gy visiting localhost:80/cgi-bin/printenv.cgi all that happened was I received a "404 Not Found" error. I looked at the apache logfile and it provided no further info.

I even tried using the "wget" command. same 404 error.

What have I done wrong?
