Perl Apache : Perl script displayed as plain text

While configuring with apache and perl cgi scripts, don’t know why index.cgi/index.pl are displayed as plain text instead of executing them.

When browser is printing code of script that means it’s unable to find the application to run the script. Below two lines should be your first steps to solve this. AddHandler will make sure files ending with .cgi and .pl to be treated as cgi scripts. And +ExecCGI option will allow to execute the script. Also make sure your script is pointing to correct perl binary location.

    AddHandler cgi-script .cgi .pl
    Options FollowSymLinks +ExecCGI

Also There are some mistakes/misconfiguration points in your httpd.conf

  • Alias line should point to cgi-bin directory where your cgi scripts are present.

ScriptAlias /cgi-bin/ “D:\webserver\cgi-bin”

  • For same cgi-bin directory following configuration should be in httpd.conf. You should replace your <Directory "D:\webserver"> part with below.
<Directory "D:\webserver\cgi-bin" />
    AddHandler cgi-script .cgi .pl
    Options FollowSymLinks +ExecCGI
    AllowOverride None  
</Directory>
  • Try running your cgi script from command line like below. It should print or run from command line first.

perl test.cgi

  • Make sure you have read-write recursive permissions to cgi-bin directory and your cgi script. And also you can create directory or file with write permissions. If not create a cgi-bindirectory at some other place where you can have write permissions and provide rather its path in alias and directory attributes in httpd.conf instead.
  • Check apache error log for exact error message every time you run into apache conf issues. It will give you good insight into the problem.

Also this link should help you.

(Extra comment, not by the original answerer: You may also need to enable the cgi module. For me, the final step to getting cgi to work on a fresh install of Apache 2 was sudo a2enmod cgi. Before I did that, the website simply showed me the contents of the script.)

sudo a2enmod cgi

apache2 Invalid command ‘SSLEngine’

Problem:

When I restart httpd, I get the following error. What am I missing?

[root@localhost ~]# service httpd restart
Stopping httpd:                                            [  OK  ]
Starting httpd: Syntax error on line 22 of /etc/httpd/conf.d/sites.conf:
Invalid command 'SSLEngine', perhaps misspelled or defined by a module not included in the server configuration

I have installed mod_ssl using yum install mod_ssl openssh

Package 1:mod_ssl-2.2.15-15.el6.centos.x86_64 already installed and latest version
Package openssh-5.3p1-70.el6_2.2.x86_64 already installed and latest version

My sites.conf looks like this

<VirtualHost *:80>
#    ServerName shop.itmanx.com
    ServerAdmin webmaster@itmanx.com

    DocumentRoot /var/www/html/magento
    <Directory /var/www/html>

Solution:

Probably you do not load the ssl module. You should have a LoadModule directive somewhere in your apache configuration files.

Something like:

LoadModule ssl_module /usr/lib64/apache2-prefork/mod_ssl.so

Usually apache configuration template has (on any distribution) a file called (something like) loadmodule.conf in which you should find a LoadModule directive for each module you load into apache at server start.

On CentOS 7 installing the package “mod_ssl” and restarting the apache server worked for me:

yum install mod_ssl
systemctl restart httpd

On many systems (Ubuntu, Suse, Debian, …) run the following command to enable Apache’s SSL mod:

sudo a2enmod ssl
