How to find out Nginx version

Nginx is a popular web server and proxy server that is used to serve dynamic and static websites. If you are running Nginx on Linux, you may need to know its version. This article will tell you how to do that.

Method 1: Using the "nginx -v" command

The first and easiest way to find out the version of Nginx in Linux is to use the"nginx -v" command.

To do this, open a terminal and type the following command:

nginx -v

After running this command in the terminal, you will see information about the version of Nginx that is installed on your server. For example:

nginx version: nginx/1.18.0 (Ubuntu)

In this example, the version of Nginx is 1.18.0.

Method 2: Using the Nginx configuration file

If you don't have access to a terminal, or you want to check the version of Nginx that is currently running, then you can use the Nginx configuration file.

To do this, follow the steps below:

1. Find the path to the Nginx configuration file. Usually this file is located in the /etc/nginx/ directory.

2. Open the Nginx configuration file using any text editor. For example:

sudo nano /etc/nginx/nginx.conf

3. Find the line that starts with"nginx/" and ends with the Nginx version.

For example:

user www-data; worker_processes auto; pid /run/nginx.pid; events { worker_connections 1024; } http { ... server_tokens off; ... }

In this example, the line"server_tokens off" has the Nginx version at the end.

Method 3: Using the "systemctl status" command

The third way to find out the Nginx version in Linux is to use the"systemctl status" command. To do this, follow the steps below:

1. Open a terminal.

2. Type the following command:

systemctl status nginx.service

3. After running this command, you will see the status information of the Nginx service that is running on your server.

In it, you can find information about the version of Nginx that is running on your server. In this example, the line"nginx.service" has the Nginx version at the end. In conclusion, there are several ways to find out the version of Nginx in Linux. You can use the"nginx -v" command, check the Nginx configuration file, or use the"systemctl status" command. Choose the appropriate method and you can easily find out the Nginx version on your server.
