Чтобы получить хост локальной базы данных MariaDB, вы можете использовать различные методы в зависимости от используемого вами языка программирования. Ниже я приведу примеры кода для разных популярных языков:

1. Python:

   import mysql.connector
   # Connect to the local MariaDB server
   connection = mysql.connector.connect(
   host="localhost",
   user="your_username",
   password="your_password",
   database="your_database"
   )
   # Retrieve the host information
   host = connection.server_host
   # Print the host
   print("Host:", host)
   # Close the connection
   connection.close()

2. Java:

   import java.sql.*;
   public class Main {
   public static void main(String[] args) {
       Connection connection = null;
       try {
           // Connect to the local MariaDB server
           connection = DriverManager.getConnection(
                   "jdbc:mysql://localhost/your_database", "your_username", "your_password");
           // Retrieve the host information
           String host = connection.getMetaData().getURL();
           // Print the host
           System.out.println("Host: " + host);
       } catch (SQLException e) {
           e.printStackTrace();
       } finally {
           // Close the connection
           if (connection != null) {
               try {
                   connection.close();
               } catch (SQLException e) {
                   e.printStackTrace();
               }
           }
       }
   }
   }

3. PHP:

   <?php
   // Connect to the local MariaDB server
   $connection = mysqli_connect("localhost", "your_username", "your_password", "your_database");
   // Retrieve the host information
   $host = mysqli_get_host_info($connection);
   // Print the host
   echo "Host: " . $host;
   // Close the connection
   mysqli_close($connection);
   ?>

4. Рубин:

   require 'mysql2'
   # Connect to the local MariaDB server
   client = Mysql2::Client.new(host: 'localhost', username: 'your_username', password: 'your_password', database: 'your_database')
   # Retrieve the host information
   host = client.info[:host]
   # Print the host
   puts "Host: #{host}"
   # Close the connection
   client.close
