If you are installing the database through the terminal;

1. open the console and use the interactive MySQL mode

use <name_of_database>;

source <path_of_.sql>

first take the backup of wordpress database from another server using below command

mysqldump -u root -p databasename > database.sql #it will create file database.sql in current directory.

Not copy that file to new server and use below command to import the database.

mysql -u root -p databasename < database.sql

you can also unzip the /var/www/website/_downloads/database.sql.zip file and directly import using below command.

mysql -u root -p database name < /var/www/website/_downloads/database.sql

provide the root password to complete import.
