In this article, we’ll explore multiple methods to check the MariaDB version in detail, complete with code snippets for better understanding.

Why Checking the MariaDB Version Matters

Before diving into the methods, let’s discuss why it’s essential to know your MariaDB version:

  1. Compatibility: Different versions of MariaDB may support different features and functions. Knowing your version helps ensure that your applications work correctly with the database.
  2. Security: Older versions may contain vulnerabilities that can be exploited. Keeping your database updated to the latest version ensures that you have the latest security patches.
  3. Performance Improvements: Newer versions often come with performance enhancements that can improve the efficiency of your queries and overall database management.

Now that we understand the importance of checking the MariaDB version, let’s explore the methods to do so.

Method 1: Using the Command Line

One of the most straightforward methods to check the MariaDB version is through the command line interface. Here’s how you can do it:

Step 1: Open the Command Line Interface

Depending on your operating system, open your terminal or command prompt.

Step 2: Connect to MariaDB

To check the version, you first need to connect to your MariaDB server. You can do this by executing the following command:

bash
mysql -u username -p

Replace username with your MariaDB username. You will be prompted to enter your password.

Step 3: Execute the Version Command

Once you’re connected, you can check the MariaDB version by executing the following command:

sql
SELECT VERSION();

This command will return the version of MariaDB you are currently using. The output will look something like this:

diff
+-----------------------+
| VERSION() |
+-----------------------+
| 10.5.9-MariaDB-1:10.5 |
+-----------------------+

This output indicates that you are using version 10.5.9 of MariaDB.

Method 2: Using the MySQL Command-Line Client

If you are not connected to the MariaDB server, you can still check the version using the MySQL command-line client. Here’s how:

Step 1: Open the Command Line Interface

As before, open your terminal or command prompt.

Step 2: Use the MySQL Command

Run the following command:

bash
mysql --version

This command will display the version of the MySQL client, which is typically the same as your MariaDB version if you have it installed. The output will look similar to this:

arduino
mysql Ver 15.1 Distrib 10.5.9-MariaDB, for osx10.15 (x86_64) using readline 5.1

Method 3: Checking MariaDB Version through PHP

If you’re developing a web application and have PHP installed, you can also check the MariaDB version using PHP code. This method is particularly useful for developers working on web projects. Here’s how you can do it:

Step 1: Create a PHP File

Create a new PHP file (e.g., check_version.php) in your web server’s root directory.

Step 2: Add the Following Code

php
<?php
$servername = "localhost";
$username = "username";
$password = "password";
// Create connection
$conn = new mysqli($servername, $username, $password);// Check connection
if ($conn->connect_error) {
die(“Connection failed: “ . $conn->connect_error);
}// Fetch version
$sql = “SELECT VERSION() as version”;
$result = $conn->query($sql);if ($result->num_rows > 0) {
// Output data of each row
while($row = $result->fetch_assoc()) {
echo “MariaDB Version: “ . $row[“version”];
}
} else {
echo “0 results”;
}$conn->close();
?>

Replace username and password with your MariaDB credentials.

Step 3: Run the PHP File

Access the file in your web browser (e.g., http://yourserver/check_version.php). You should see the MariaDB version displayed on the screen.

Method 4: Using a Database Management Tool

If you prefer using a graphical user interface (GUI) for managing databases, many database management tools can help you check the MariaDB version easily. Tools like phpMyAdmin, MySQL Workbench, and Adminer provide an intuitive interface for database management.

By Using phpMyAdmin

  1. Log in to phpMyAdmin: Open phpMyAdmin in your web browser.
  2. Look at the Home Page: Upon logging in, you should see the version of MariaDB listed on the home page, typically at the bottom.

Using MySQL Workbench

  1. Connect to Your Database: Open MySQL Workbench and connect to your MariaDB server.
  2. View Server Status: Click on the Server menu and then select Server Status. The version information will be displayed in the server status window.

Using Adminer

  1. Open Adminer: Access Adminer through your web browser.
  2. Login: Enter your MariaDB credentials to log in.
  3. Version Information: The version is usually displayed on the main page after logging in.

Method 5: Checking the Configuration Files

Another method to check the MariaDB version is by looking into the configuration files. While this is less common, it can still be useful in some cases.

  1. Locate the Configuration File: The configuration file (usually named my.cnf or my.ini) can typically be found in the /etc/mysql/ directory on Linux or in the installation directory on Windows.
  2. Open the File: Use a text editor to open the file and look for a line containing the version information. It might look something like this:
csharp
[mysqld]
version=10.5.9-MariaDB
