Create a basic script

vim /var/www/cgi-bin/mytime.sh
 
#!/bin/bash
echo -e "Content-type: text\n"
echo "This is the current time on the system: $(date)"

• Note: There MUST be a newline after the “Content-type: text” line in order for the cgi script to work correctly. (Either in the form above with 'echo -e' and the '\n' or another empty echo command)

Make script executable

chmod +x /var/www/cgi-bin/mytime.sh

Find SELinux CGI boolean to ensure its on

getsebool -a | grep httpd_enable_cgi

If OFF, set it to ON

setsebool -P httpd_enable_cgi 1
