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 apache2 500 internal server error 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. 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.

Page 1 of 2 1 2 Next > MaRiOs Guest 0 Hello ppl, I need some more automatic things to put in plesk so https://www.1and1.com/cloud-community/learn/web-server/server-management/how-to-fix-http-error-code-500-internal-server-error/ 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 internal server 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 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 internal server error 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 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 C
