I use to have a hard time configuring a new site under a common VPS. So I decided to document the steps for easy reference in future.
Following are the steps to add a new site “site-name.com” under a new user account “username” on your Linux VPS. This is to note that this works if you have the following web service solution stack (LAMP):
Linux OS : Debian
Web server: Nginx (Not Apache)
Database: MySQL
Application Programming Language: PHP
So here we go:
1. Buy the domain. Call it site-name.com.
2. Set the nameserver of the domain to point to the IP address of your VPS under ‘A’ record which stands for ‘Address’. For reference, there are other kinds of record like ‘CNAME’ and ‘MX’, but you don’t need to set them at this point.
3. Create a new user on VPS by command by following command.

sudo adduser username

This command also creates a new home directory for the user.
