Satellite 5.7 Installation problem.

Hi Gurus,

I need help in setting up my rhn satellite.
I have installed it but during installation at one point it says where is the certificate file ?
I don't know how to handle that and which certificate it is asking for activating satellite.
Isn't it possible to install and activate satellite in disconnected environment ?
how can i resolve this ?
I did ctrl+c and tried web login where looks like httpd is running so it gives a page with a bold error "Error 404 File Not found"
i tried did restarting rhn satellite where i see this error comes in while startup

Starting osa-dispatcher: Spacewalk 8881 2015/06/23 01:34:37 +05:30: ('Invalid SSL certificate:', Unable to read file /var/www/html/pub/RHN-ORG-TRUSTED-SSL-CERT)

please help I am newbie to it.

Thanks in advance
Sandeep
