Apache Cgi-bin 500 Internal Server Error
Server Error ...and how to fix it. The short answer: this is usually a permissions error on your CGI script, which is easy to fix. Go to your FTP client, or your website file manager, internal server error cgi-bin apache and highlight or right-click on the CGI script. Then choose Properties, or Permissions, or "Chmod", and set it to world-executable: that's 0755, or a+rx, or -rwxr-xr-x. Do NOT use 0777 (a+rwx or -rwxrwxrwx). And your cgi-bin directory itself should also be 0755, not 0777. The long answer: when running a Perl CGI script like FileChucker or UserBase, you may see the "Internal Server Error" message in your browser. The message 500 internal server error apache php will usually also say something like "please check the server's error-log for more information." You should do that -- the message printed to the error log will often tell you exactly what the problem is. The Apache error log, for example, is often located at /var/log/apache/error_log or /var/log/apache2/error_log (or sometimes "error.log"). If you don't have access to the error log, the next simplest thing to do is to make a backup copy of the script, then open the original and delete all of its contents, and add just these 3 lines to the file: #!/usr/bin/perl print "Content-type: text/plain\n\n"; print "testing...\n"; (Note: if the server is a Windows system, then replace the first line above with either #!perl or #!c:\path\to\perl.exe.) Now try to access the page in your browser again. If it works (you see "testing..." as its output) then you know that your server is at least configured properly for running Perl CGI scripts. If it doesn't work, then that may mean the problem is in the server configuration, rather than with your CGI script. (For example, are you sure you actually have Perl installed? Virtually all UNIX/Linux/OS X servers do, but Windows servers usually need to have it installed manually, from a free package like Activ

What Is An Internal Server
to give you some concrete, practical steps that you can take to narrow down the problem and hopefully eliminate it. For the uninitiated, a "500 Internal Server Error" is a https://encodable.com/internal_server_error/ 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, http://www.thesitewizard.com/archive/servererror.shtml 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 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. Per

Page 1 of 2 1 2 Next > MaRiOs Guest 0 Hello ppl, I need some more automatic things to put in https://talk.plesk.com/threads/500-internal-server-error-when-trying-to-run-a-cgi-script.58121/ plesk so I said I must begin learning perl to write my own scripts. I made a very easy one that just prints 2 words and i uploades to the cgi-bin area... (its the first time Im using https://www.a2hosting.com/kb/developer-corner/apache-web-server/troubleshooting-cgi-scripts the cgi-bin). so when i try to run the script i get : 500 Internal Server Error .... the link is : http://www.mariosmaravelias.info/cgi-bin/test.cgi what am I doing wrong? MaRiOs, Jul 23, 2005 #1 jamesyeeoc Guest 0 internal server Could you post this script? Have you checked your log files? /var/log/messages /home/httpd/vhosts/mariosmaravelias.info/statistics/logs/access_log /home/httpd/vhosts/mariosmaravelias.info/statistics/logs/error_log jamesyeeoc, Jul 23, 2005 #2 MaRiOs Guest 0 #!/usr/bin/perl $name="Hello World"; print $name; i cantbe more simple than that MaRiOs, Jul 23, 2005 #3 jamesyeeoc Guest 0 And what about your log files, any errors or messages relating to this problem?? You should be seeing 'Premature end of script headers: test.cgi' in your error_log file Common solutions internal server error to this are: 1) Copy psa-suexec to suexec: cp /usr/sbin/psa-suexec /usr/sbin/suexecClick to expand... 2) Permissions: chmod -R 755 /home/httpd/vhosts/yourdomain.com/cgi-binClick to expand... 3) Ownership: chown -R ftpusername : psacln /home/httpd/vhosts/yourdomain.com/cgi-binClick to expand... (without the spaces around the colon : ) 4) File is ASCII: If you uploaded the file using FTP, it may have been uploaded in binary mode instead of ASCII, reupload it as ASCII. Then restart apache: service httpd restartClick to expand... In some cases, a whole server restart is necessary, not just apache restart. These have solved the same problem for countless others here on the forum. jamesyeeoc, Jul 23, 2005 #4 MaRiOs Guest 0 Ok I did these : 1)cp: `/usr/sbin/psa-suexec' and `/usr/sbin/suexec' are the same file 2)Done 3)Done 4) i didnt upload it , I loged in ssh and i made the file with nano editor. 5) ok i will try to restart it. about the error log files i dont see anythin about the script.. the only error i see is : [Mon Jul 25 12:29:05 2005] [warn] RSA server certificate CommonName (CN) `plesk' does NOT match server name!?

Troubleshooting CGI scripts Step #1: Verify script file permissions Step #2: Verify the shebang Step #3: Run the script from the command line Step #4: Check web server error logs Step #5: Open a ticket with the Guru Crew Troubleshooting CGI scripts If you have a CGI (Common Gateway Interface) script that is not working, you can follow these troubleshooting steps: Step #1: Verify script file permissions A2 Hosting's shared web servers run CGI scripts under your user ID. If a CGI script does not run, one of the most common causes is that the execute permission is not set on the file. Make sure that the CGI script file has the correct permissions set: For more information about file permissions for Perl script files, please see this article. Step #2: Verify the shebang Make sure the CGI script file uses the correct shebang. CGI script files must start with the correct shebang, or else the Apache web server will not know how to run the file. For more information about the shebang and how to use it, please see this article. Step #3: Run the script from the command line Trying to debug a CGI script through a web browser is often a frustrating process. For example, if you receive a "500 Internal Server Error", the root cause could be file permissions, a syntax error, or something else entirely. You can obtain much more useful information about script errors by logging in to your SSH account and running the script from the command line. Step #4: Check web server error logs The web server's error log may contain valuable information about why a CGI script is not running. Scripts that cause a "500 Internal Server Error" or "403 Forbidden" error message are logged in the web server's error log. You can use cPanel to view the error log for
