problem uploading of wordpress site to Linux server

I have cloud hosting account. When I opened the acct, they provisioned the server(Linux) and let me installed the wordpress with it. I already created a website with that. Now I insatalled XAAMP, phpmyadmin, wordpress in my pc and created my own website with another domain name. I uploaded the website to my cloud hosting server, but do not see the site in web. What am I doing wrong? I do not have control panel to the server. Do I have to installed the above programs that I did in my local machine?

I spent hours and hours in the web and youtube, unfortunately did not find solution. It is basically 2 different domains under one IP address in hosting acct. Need help. Thank you.
