Apache/Httpd /Var/Www/HTML/ .Cgi Scripts Throw 500 Internal Server Error

Apache/httpd /var/www/html/ .cgi scripts throw 500 internal server error

I just solved reinstalling the server and doing all over again, disabled selinux and iptables, because I have already an external firewall.

Thanks to anyone who helped me out ;)

500 internal Server error when configuring python cgi

Your CGI script must also output header information.

The minimum required is the Content-type header -- which in this case should be set to text/html.

Add this to the start of your CGI script (before you print anything else).

print 'Content-type: text/html\n'

Take note of the extra trailing newline -- its necessary to leave at least one blank line between the header(s) and the content itself.

Update:

For further troubleshooting, do the following:

1. Make sure your CGI script has the correct permissions set: chmod 0755 hello.py just to be sure.
2. Your script appears to be .py whereas your apache config appears to only specify .cgi files. Your AddHandler should be AddHandler cgi-script .cgi .py.
3. You should symlink your /etc/apache2/conf-available/crunchworld.conf file in /etc/apache2/conf-enabled if you haven't already done so. Do so by running the following: cd /etc/apache2/conf-enabled; sudo ln -s ../conf-available/crunchworld.conf.
4. Always remember to restart apache if you make any changes to your apache config: e.g. sudo service apache2 restart.
5. Check that your hashbang line is correct. Does /usr/bin/python2.7 exist? You can try setting instead to #!/usr/bin/env python or #!/usr/bin/env python2. (Or better yet, switch to python3 if possible on your system).
6. Check the apache error logs once again. E.g. tail -20 /var/log/apache2/error.log (or wherever your logs are).
7. You can attempt further debugging with the cgitb module (see https://docs.python.org/3/library/cgitb.html).

CGI script not running, Internal Server Error (500) Error

Try running:

perl -c /var/www/cgi-bin/upload.cgi

Quote from perldoc perlrun:

   -c   causes Perl to check the syntax of the program and then exit
        without executing it.  Actually, it will execute "BEGIN",
        "UNITCHECK", "CHECK", and "use" blocks, because these are
        considered as occurring outside the execution of your program.
        "INIT" and "END" blocks, however, will be skipped.

Python CGI getting 500 Internal Server Error

Every thing was fine except cgi-bin directory's permission.

Change the permission (chmod) of cgi-bin to 755 from 777.

internal server error (500) in simple cgi script

You might need a #!/usr/bin/python at the top of your script to tell Apache to use Python to execute it. At least, I did that and it worked for me :-) .
