To connect to a MySQL database, you need to provide the following information:

1. `host`: The hostname or IP address of the MySQL server.2. `user`: The username for the MySQL account.3. `password`: The password for the MySQL account.4. `database`: The name of the database you want to connect to.

Please replace the placeholders `your_username`, `your_password`, and `your_database` with your actual MySQL credentials and database name. If you're connecting to a remote MySQL server, make sure to use the correct hostname or IP address.

Once you have provided the correct information, the code will establish a connection to the MySQL database and print a success message if the connection was successful. If the connection fails, it will print an error message.

After you have finished working with the database, it's important to close the connection to free up resources. This is done using the `connection.close` method.
