MySQL is a popular choice for managing databases in web applications, known for its reliability, ease of use, and security. Over time, MySQL has introduced many versions, each bringing new features, security improvements, and bug fixes. Checking your MySQL version is essential for understanding compatibility and ensuring your applications are optimized and secure.

This article will show you several methods for checking your MySQL version using the command line.

Why Check Your MySQL Version?

Knowing your MySQL version helps you:

• Determine compatibility with software or applications.
• Plan for potential configuration changes or optimizations.
• Ensure that you're using the latest features and security patches for a stable, secure environment.

Method 1: Using SSH Shell

SSH (Secure Socket Shell) is a secure protocol for remote access to your server, enabling you to execute commands on the server from any location.

To connect to your server using SSH, you can:

• Use a client like PuTTY (for Windows users).
• Use the command line or Terminal (available on Windows PowerShell, macOS, and Linux).

To check your MySQL version through SSH:

1. Connect to your server via SSH.
2. Run the following command in the terminal:
    

    

   mysql -V
   This command returns the MySQL version, as shown here:
    

   mysql Ver 14.14 Distrib 5.7.32, for Linux (x86_64) using EditLine wrapper

Method 2: Using the MySQL Shell

The MySQL Shell provides an interactive environment for managing MySQL databases, supporting scripting in JavaScript and Python.

To check the MySQL version in MySQL Shell:

1. Access MySQL by running:
    

   mysql -u [your_username] -p
   Replace [your_username] with your MySQL username. You’ll be prompted for your password.
2. After logging in, you’ll see the MySQL version displayed in the welcome message.
3. For additional details, type:
    

   SHOW VARIABLES LIKE '%version%';
   This command displays various version-related information, helping you verify the exact MySQL version and build.

Understanding the MySQL Naming Scheme

MySQL versions follow a naming convention with three numbers (e.g., 8.0.23), each representing specific details:

• First Number: Major version (e.g., 8 in 8.0.23).
• Second Number: Minor version, indicating feature stability within the major version.
• Third Number: Bug-fix release, which reflects ongoing improvements to address issues.

Suffixes like dmr (Development Milestone Release) or rc (Release Candidate) may follow the version number, indicating that the version is still in testing stages. Only General Availability (GA) releases are recommended for production environments.

Ensuring You’re Running the Latest MySQL Version

Staying up-to-date with the latest MySQL GA (General Availability) release is recommended for production environments. Regularly updating your MySQL version ensures your server benefits from the latest security patches, bug fixes, and performance enhancements.

Quick Summary of Steps:

1. Use mysql -V for a quick version check.
2. Use the MySQL Shell with SHOW VARIABLES LIKE '%version%'; for more details.
3. Verify that you’re running a stable GA version without suffixes for optimal reliability.
