What is NGINX?

NGINX (pronounced “engine-x”) is a free, open-source web server software that can also be used as a reverse proxy, load balancer, and HTTP cache. It was created by Igor Sysoev in 2002 to solve the C10k problem, which refers to the challenge of handling more than 10,000 concurrent connections on a single server.

Importance and Use Cases

NGINX is widely used due to its high performance, scalability, and reliability. Some common use cases include:

Serving static web content
Reverse proxying for web servers like Apache or IIS
Load balancing for multiple web servers
Caching frequently requested resources
Securing web applications with SSL/TLS encryption

Installing NGINX on Ubuntu 22.04

Step 1: Update the Package Index

Before installing NGINX, update the package index to ensure you have access to the latest packages:

sudo apt update

This command retrieves the latest package information from the configured repositories.

Step 2: Install NGINX

Install NGINX using the following command:

sudo apt install nginx

This will download and install the NGINX package, along with its dependencies.

Step 3: Verify NGINX Installation

Verify that NGINX is installed correctly by checking the version number:

nginx -v

You should see a response indicating the version of NGINX you just installed.

Step 4: Start and Enable NGINX

Start the NGINX service and enable it to start automatically on boot:

sudo systemctl start nginx
sudo systemctl enable nginx

These commands ensure that NGINX is running and will continue to run after a system reboot.

Step 5: Configure the Firewall (Optional)

If you have a firewall enabled, you may need to allow HTTP and HTTPS traffic. You can do this using the following command:

sudo ufw allow 'Nginx Full'

This command allows incoming traffic on ports 80 (HTTP) and 443 (HTTPS).
