Do you use LiteSpeed Enterprise or OpenLiteSpeed?
There could be a lot to learn. First, suggest you install cypberpanel with LiteSpeed Web server. It should be much easier.
Second, go through cypberpanel and LiteSpeed doc on how to setup virtual host for each web site.
Third, importing MySQL database is not part of the web server function, but if you have cyberpanel and phpmyadmin, you can import database by login. If you don't have cyberpanel, just search from MySQL forum how to import MySQL database.
