Connect to the MySQL server, input the following command, and press the Enter key:

   mysql -u <用户名> -p

“” is your MySQL username. This will prompt you to enter your password.

3. Enter the password and press the Enter key, then you will successfully log in to the MySQL server.

   SHOW DATABASES;

This will display a list of all databases on the current server.
