As an NGINX administrator, knowing how to check your NGINX version is crucial for ensuring the security, stability, and performance of your web server. In this tutorial, we’ll explore why checking your NGINX version matters, and provide a step-by-step guide on how to do it.

Why Check Your NGINX Version?

Before we dive into the nitty-gritty of checking your NGINX version, let’s first understand why it’s essential. Here are three key reasons:

1. Security: New versions of NGINX often include security patches and updates that fix vulnerabilities in previous versions. By knowing your current version, you can ensure you’re running a secure web server.
2. Compatibility: Different versions of NGINX may have varying levels of compatibility with other software and plugins. Knowing your version helps you choose compatible tools and avoid potential conflicts.
3. Performance Optimization: Newer versions of NGINX often include performance enhancements and optimizations that can improve the speed and efficiency of your web server.

Step-by-Step Guide to Checking Your NGINX Version

Now that we’ve covered the importance of checking your NGINX version, let’s move on to the step-by-step guide. Here are three methods to check your NGINX version:

Method 1: Using the Command Line

You can use the following command in your terminal or command prompt:

nginx -v

This will display the current version of NGINX installed on your system.

Method 2: Checking the Configuration File

Open the nginx.conf file (usually located at /etc/nginx/nginx.conf) and look for the line that starts with version. This will indicate the version of NGINX you’re running.

sudo nano /etc/nginx/nginx.conf

Method 3: Using the http Block

Create a new file in your web root directory (e.g., /var/www/html/version.php) and add the following code:

<?php echo $_SERVER['SERVER_SOFTWARE']; ?>

Then, access this file through your web browser by visiting http://yourdomain.com/version.php. The output will display the current version of NGINX.

Real-World Scenario: Upgrading to a Newer Version

Let’s say you’re currently running NGINX 1.16 and want to upgrade to the latest version, NGINX 1.18. After checking your current version using one of the methods above, you can proceed with the upgrade process.

Here are the general steps:

1. Backup your existing configuration files and data.
2. Stop the NGINX service.
3. Download and install the new version of NGINX.
4. Update your configuration files to reflect any changes in the new version.
5. Restart the NGINX service.
