Apache2 Perl Cgi Internal Server Error
Contents |
of questions I get from my visitors at thesitewizard.com, I can see that one of the most dreaded errors that newcomers to CGI face is the "500 Internal Server Error". It is one of the most uninformative error messages that apache perl internal server error can mean anything from an improper upload to a bug in the script. This article
Apache Cgi 500 Internal Server Error
attempts to give you some concrete, practical steps that you can take to narrow down the problem and hopefully eliminate it. For the apache2 enable cgi uninitiated, a "500 Internal Server Error" is a message much like the common "404 File Not Found" message. You get the latter message in your browser when you try to access a non-existent web page. You get the

"500 Internal Server Error" message when you try to run a script with problems. For the purposes of this article, I am assuming that your CGI script is a Perl script, by far the most commonly available on the Internet. We will try to eliminate the most common errors first (and the easiest-to-eliminate ones): Location Did you upload your scripts into the right place? This is not as obvious as it may seem. Some servers how to run cgi script in apache ubuntu are configured to run your CGI scripts anywhere. Others will only run it when it is installed in a particular directory. It is not just a matter of creating a "cgi-bin" directory — for example, some hosts configure the server so that it will run scripts only from a particular directory outside the web directory structure (for security reasons). Your web page will still call the script "/cgi-bin/script.pl" but the server maps it to the actual directory. You will have to upload it in the right directory, regardless of what your web page calls it. Find out such information from your web host's documentation. File Upload Mode Did you upload your Perl script in ASCII mode? Your FTP client may have uploaded the script in binary mode if you did not take any special action. Perl scripts are ASCII files, and since different operating systems have different ways of representing the end of line character (eg Unix uses a line-feed, Windows uses a carriage-return and line-feed pair), it is important that you set the uploading method to ASCII, so that line-end translation is performed. Re-upload the script, this time making sure that it was uploaded in Text or ASCII mode. Do not use any auto-detection options since the FTP program might assume the extensions you are using for your scripts are for binary files. F

After running these lines ( a fellow stackoverflow member suggested running these).. cd /etc/apache2/mods-enabled sudo ln -s ../mods-available/cgi.load . sudo ln -s ../mods-available/cgid.load . sudo service apache2 restart I placed the cgi files ( they are perl ones ) into my Apache2's cgi-bin @ /usr/lib/cgi-bin. When typing localhost/cgi-bin/test.cgi, I got a 500 Internal server error. This is what the Server error log says..
