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, 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.
Internal Server Error Apache2
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 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\

I created a simple printenv.pl script and put it in the following directory $ mv printenv.pl /usr/lib/cgi-bin/ $ chmod +rx /usr/lib/cgi-bin/printenv.pl However when I go to http://127.0.0.1/cgi-bin/printenv.pl, I get a 500 Internal Server Error I checked the error log at /var/log/apache2, and this is what it says: [Mon Oct 24 11:04:25 2011] [error] (13)Permission denied: exec of '/usr/lib/cgi-bin/printenv.pl' failed [Mon Oct 24 11:04:25 2011] [error] [client 127.0.0.1] internal server error Premature end of script headers: printenv.pl Any suggestions on how I can fix this and run CGI scripts on my localhost? apache2 perl webapp-development share|improve this question edited Jan 10 '12 at 3:58 Jjed 9,39055385 asked Oct 24 '11 at 15:15 itcplpl 613 add a comment| 2 Answers 2 active oldest votes up vote 2 down vote I had this problem as well. It turned out that I had set the .pl files permissions to 775. Apache does not allow user writable. Try changing your .pl file permissions to 755. If that isn't it, check your web site permission settings in /etc/apache2/sites-available. share|improve this answer edited Jan 7 '12 at 2:25 James♦ 31.1k44133224 answered Jan 6 '12 at 4:36 John 212 add a comment| up vote 2 down vote I had this exact problem (with the exact same paths, directories, permissions, etc.) just a little while ago, and all of a sudden understood what I read somewhere in the Apach2 documentation about a week ago. That is this - everything you have set up so far is fine, but for security reasons, apache will not run any file (CGI, Perl, C, etc.) unless its write permission (w) is removed completely. Make the permissions look like this: -r-xr-xr-x Then it should work just fine. Hope this helps, let me know if it still doesn't work. share|improve this answer edited Oct 5 '12 at 4:03 Peachy 4,10252637 a
in the script or the server's inability to understand it, and is not an error caused on your end. The error resides solely on the server that hosts the website. 500 error user troubleshooting Despite the issue being something you can't control or fix directly, there are a few things you can try to rectify the problem from your computer. Try reloading the web page (press F5) to see if the error can be cleared up. Try coming back to the web page at a later time. If you're not the webmaster, it's likely that they are working on the problem. Contact the webmaster by e-mail. Many web pages have a link on it to contact the company (support email) or the server hosted the page. In any case, just know that you did not cause the error and your computer or Internet connection are not at fault. 500 error webmaster troubleshooting If you are responsible for the script or page generating this error, below are steps that can be taken to help identify and fix this error with your script. Script is not set as executable All scripts uploaded to a server must have execute permissions (e.g. chmod 755 or -rwxr-xr-x). If you are uploading the file through a graphical FTP program such as FileZilla, right-click the file on the Server and click File permissions to see the permissions. File is not being uploaded as ASCII (Text) When uploading any Perl or PHP script file you need to make sure that the file is uploaded in ASCII (Text) mode and not Binary mode. If your program is uploading the files and mode is automatically be set, try switching to manual and make sure it is ASCII (Text) mode. Perl script doesn't have a shebang or content-Type If you are uploading a Perl script (files ending with .pl or .cgi,) it must have a shebang as the first line and a content-Type line before any print command. Below is what we recommend having at the top of all your Perl script file. Adding the fatalstobrowser line to our script will print any error to the browser window, which helps debug the script if there are errors in it
