Internal Server Error Cgi-bin Apache
up Why does my Perl CGI script cause a 500 internal server error? up vote 3 down vote favorite I get a 500 internal server error when I try to run the code below in a web server which supports perl: #! /usr/bin/perl use LWP; my $ua = LWP::UserAgent->new; $ua->agent("TestApp/0.1 "); $ua->env_proxy(); my $req = HTTP::Request->new(POST => 'http://www.google.com/loc/json'); $req->content_type('application/jsonrequest'); $req->content('{ "cell_towers": [{"location_area_code": "55000", python cgi 500 internal server error "mobile_network_code": "95", "cell_id": "20491", "mobile_country_code": "404"}], "version": "1.1.0", "request_address": "true"}'); my $res = $ua->request($req); if ($res->is_success) { print $res->content,"\n"; } else { print $res->status_line, "\n"; return undef; } But there is no error when I run the code below: #! /usr/bin/perl use CGI::Carp qw(fatalsToBrowser); print "Content-type: text/html\n\n"; print "\n"; print "
Hello World!
\n"; foreach $key (sort keys(%ENV)) { print "$key = $ENV{$key}
" ; } print "\n"; print "\n"; So I think there is some problem with my code. When I run the first perl script in my local machine with the -wc command, it says that the syntax is OK. Help me please. perl cgi share|improve this question edited May 21 '10 at 0:26 brian d foy 87.1k24150391 asked May 20 '10 at 8:19 Nitish 60151127 1 When you have trouble with a Perl CGI script, go through my "Troubleshooting Perl CGI Script": stackoverflow.com/questions/2165022/… –brian d foy May 21 '10 at 0:26 I don't know whether this helps but I got my perl-cgi script working after I put shebang line #!C:\Strawberry\perl\bin\perl –user966588 Mar 11 '12 at

The http://stackoverflow.com/questions/2872040/why-does-my-perl-cgi-script-cause-a-500-internal-server-error 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. Do NOT use https://encodable.com/internal_server_error/ 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\to\perl.exe.) Now try to access the page
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 http://www.computerhope.com/issues/ch001294.htm 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 https://talk.plesk.com/threads/500-internal-server-error-when-trying-to-run-a-cgi-script.58121/ 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 internal server 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 internal server error 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. #!/usr/bin/perluse strict;use CGI::Carp qw( fatalsToBrowser carpout);print "Content-Type: text/html", "\n\n"; Not uploaded to the correct directory Make sure the script file is being uploaded to a directory that has e

Page 1 of 2 1 2 Next > MaRiOs Guest 0 Hello ppl, I need some more automatic things to put in 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 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 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 do
