WARNING: Running bash scripts via CGI can be dangerous and should only be done in isolated environments.

/apache

Enable the required Apache modules:

# Enable mod_cgid in the Apache config
echo "LoadModule cgid_module modules/mod_cgid.so" >> /etc/httpd/conf/httpd.conf

# Add CGI configuration
echo "ScriptAlias /cgi-bin/ \"/srv/http/cgi-bin/\"" >> /etc/httpd/conf/httpd.conf
echo "<Directory \"/srv/http/cgi-bin\">" >> /etc/httpd/conf/httpd.conf
echo "    AllowOverride None" >> /etc/httpd/conf/httpd.conf
echo "    Options +ExecCGI" >> /etc/httpd/conf/httpd.conf
echo "    Require all granted" >> /etc/httpd/conf/httpd.conf
echo "</Directory>" >> /etc/httpd/conf/httpd.conf

# Restart Apache
systemctl restart httpd

/directories

Create a CGI-bin folder for the scripts:

mkdir -p /srv/http/cgi-bin
chown http:http /srv/http/cgi-bin
chmod 755 /srv/http/cgi-bin

/template

Use this header for your CGI scripts:

#!/bin/bash
echo "Content-type: text/html"
echo ""
echo "<meta charset='utf-8'>"

/permissions

# Make the script executable
chmod +x /srv/http/cgi-bin/myscript.sh

# Test the script works
/srv/http/cgi-bin/myscript.sh
