codeigniter on server redhat

[eluser]redraw[/eluser]
dear all

i put my site(codeigniter) on redhat server (var/www/html) but when i call it (http:\ip_server\my_web\) from client computer it goes blank..

i already set up database host to 192.168.0.1
i already set up config.php (base_url to http:\\192.168.0.1\my_web)
i already test to put simple php to server then it opened when i call it

any suggestion?

Thanks
