How to preview a website with the ipaddress

Hi good day.

Im new on this panel and i really like it, im setting up a new vps, i have created a new account and i can access via FTP, all fine.

I have uplooaded all my files, but i would like to check if everything is executing normally befoore i change the DNS of my domain. How can i preview the website?

in other panels, i had to write the ip address, and the account name, something like this: 111.111.111/~accountname and i would be able to visualize the website.

But i dont find any way to do this on this panel. How can i do this?

Im sorry if is a noob questioon. thanks in advance!

Im sorry... i posted this on the wrong place?

you can add mod_userdir to your apache server.

How to enable "mod_userdir"

Tell me step wise how to do

by default this is enabled

You can access your website on IP .  http://YourIP/~username     its same like Cpanel 

Its better than cpanel
