In this comprehensive tutorial, we’ll walk you through the process of installing NGINX on Ubuntu. Whether you’re a seasoned developer or just starting out, this guide will provide you with the knowledge and skills needed to master NGINX.

NGINX is a popular open-source web server software that can be used as a reverse proxy, load balancer, and HTTP cache. It’s known for its high performance, scalability, and reliability, making it a favorite among developers and system administrators alike. In this article, we’ll focus on installing NGINX on Ubuntu, one of the most popular Linux distributions.

What is NGINX?

Before we dive into the installation process, let’s take a brief look at what NGINX is and why you might want to use it.

NGINX (pronounced “engine-x”) is a web server software that can handle multiple tasks simultaneously. It was created by Igor Sysoev in 2002 and has since become one of the most popular web servers in the world. NGINX is known for its:

• High performance: NGINX can handle thousands of concurrent connections with minimal resource usage.
• Scalability: NGINX can be easily scaled to meet the needs of large, high-traffic websites.
• Reliability: NGINX has a reputation for being stable and reliable, even under heavy loads.

Why Use NGINX?

So why would you want to use NGINX? Here are just a few reasons:

• Speed: NGINX is incredibly fast, making it ideal for high-traffic websites.
• Security: NGINX has built-in security features, such as SSL/TLS support and Web Application Firewall (WAF) integration.
• Flexibility: NGINX can be used as a reverse proxy, load balancer, and HTTP cache.

Installing NGINX on Ubuntu

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

Step 1: Update Your Package List

Before we install NGINX, we need to make sure our package list is up-to-date. Open your terminal and run the following command:

sudo apt update

This will update your package list with the latest available packages.

Step 2: Install NGINX

Next, we’ll install NGINX using the apt package manager. Run the following command:

sudo apt install nginx

This will download and install NGINX on your Ubuntu system.

Step 3: Verify NGINX Installation

To verify that NGINX has been installed correctly, run the following command:

nginx -v

This should display the version of NGINX that you just installed.

Step 4: Start NGINX Service

Finally, we need to start the NGINX service. Run the following command:

sudo systemctl start nginx

This will start the NGINX service and make it available on your system.

Configuring NGINX

Now that we’ve installed NGINX, let’s take a look at how to configure it. NGINX configuration files are located in the /etc/nginx directory. The main configuration file is nginx.conf.

Here’s an example of what the default nginx.conf file might look like:

http {
    server {
        listen 80;
        server_name localhost;

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

This configuration tells NGINX to listen on port 80 and serve files from the /var/www/html directory.

Summary

In this article, we’ve covered the basics of NGINX and how to install it on Ubuntu. We’ve also taken a brief look at configuring NGINX using the nginx.conf file.

Here are the key points to take away:

• NGINX is a high-performance web server software that can be used as a reverse proxy, load balancer, and HTTP cache.
• Installing NGINX on Ubuntu is straightforward using the apt package manager.
• The main NGINX configuration file is nginx.conf, located in the /etc/nginx directory.
