Learn how to install NGINX on Ubuntu 22.04 and take the first step towards becoming an NGINX expert.

NGINX is a powerful, open-source web server that can handle high traffic and large volumes of data. It’s widely used in production environments due to its reliability, flexibility, and scalability. In this article, we’ll guide you through the process of installing NGINX on Ubuntu 22.04.

What is NGINX?

Before we dive into the installation process, let’s take a brief look at what NGINX is and why it’s important.

NGINX (pronounced “engine-x”) is a web server software that can also act as a reverse proxy, load balancer, and HTTP cache. It was created by Igor Sysoev in 2002 and has since become one of the most popular web servers in the world.

Why Use NGINX?

NGINX offers several advantages over other web servers:

1. High Performance: NGINX is designed to handle high traffic and large volumes of data with ease.
2. Flexibility: NGINX can be used as a web server, reverse proxy, load balancer, and HTTP cache.
3. Scalability: NGINX can scale horizontally and vertically to meet the needs of your application.

Use Cases for NGINX

NGINX is commonly used in various scenarios:

1. Web Serving: NGINX can serve static web content, such as images, videos, and HTML files.
2. Reverse Proxying: NGINX can act as a reverse proxy to distribute incoming requests across multiple servers.
3. Load Balancing: NGINX can balance traffic between multiple servers to ensure high availability.

Installing NGINX on Ubuntu 22.04

Now that we’ve covered the basics of NGINX, let’s move on to installing it on Ubuntu 22.04.

Step 1: Update the Package Index

Before installing NGINX, update the package index using the following command:

sudo apt update

This ensures that you have the latest package information and avoids any potential issues during installation.

Step 2: Install NGINX

Install NGINX using the following command:

sudo apt install nginx

The installation process may take a few minutes to complete.

Step 3: Verify NGINX Installation

Verify that NGINX has been installed correctly by checking the version number:

nginx -v

This should display the version number of NGINX installed on your system.

Step 4: Start and Enable NGINX Service

Start the NGINX service using the following command:

sudo systemctl start nginx

Enable the NGINX service to start automatically on boot:

sudo systemctl enable nginx

Configuring NGINX

NGINX has a vast range of configuration options. Let’s take a look at some basic configurations.

Step 1: Create a New Configuration File

Create a new configuration file for your website or application:

sudo nano /etc/nginx/conf.d/mywebsite.conf

This will open the Nano editor, where you can create a new configuration file.

Step 2: Add Basic Configuration Settings

Add basic configuration settings to the file:

server {
    listen 80;
    server_name example.com;

    location / {
        root /var/www/html;
        index index.html;
    }
}

This configuration sets up a basic web server that listens on port 80 and serves files from the /var/www/html directory.

Step 3: Reload NGINX Configuration

Reload the NGINX configuration to apply the changes:

sudo nginx -s reload
