In today’s digital world, having a fast website is essential. NGINX stands out as a high-performance web server offering exceptional speed. If you’re using Ubuntu and looking to install NGINX, you’ve come to the right place. In this article, we’ll look at how to install NGINX on Ubuntu 22.04.
Before getting to the heart of the matter, the first crucial step is to prepare your Ubuntu 22.04 system environment.
This is the foundation on which NGINX will operate. Make sure your system is up to date by executing the following commands in the terminal:
sudo apt update && sudo apt upgrade
This command updates the list of available packages and upgrades all packages on your system to the latest versions.
Also make sure your system has all the necessary tools installed. If not, install them using the following command:
sudo apt install curl gnupg2 ca-certificates lsb-release
By installing these dependencies, you ensure a smooth and seamless installation of NGINX on Ubuntu.
Having prepared your system environment, let’s move on to the main step: installing NGINX on Ubuntu 22.04.
The procedure is simple and straightforward. Follow the steps below for a successful installation.
Type the following command in the terminal and press Enter :
sudo apt install nginx
This command requires administrator rights to install the NGINX package on your system.
Starting and activating the NGINX service
Now that NGINX is installed on your Ubuntu 22.04 system, it’s essential to ensure that the service is active and working properly.
Here’s how to start and activate the NGINX service.
To start the NGINX service, open the terminal and run the following command:
sudo systemctl start nginx
This command starts the NGINX service, enabling your web server to begin serving web pages.
To ensure that NGINX starts automatically each time the system is booted, use the following command:
sudo systemctl enable nginx
By activating NGINX, you ensure that it’s always up and running whenever your system is operational, guaranteeing constant availability of your website.
To confirm that the NGINX service is active and running, run this command:
sudo systemctl status nginx
A positive response indicates that NGINX is working correctly.
You should see a status indicating that the service is active and running.
UFW firewall configuration
Once NGINX has been installed and activated on your Ubuntu 22.04 system, it’s essential to configure the UFW (Uncomplicated Firewall) correctly to ensure optimum security and functionality of your web server.
Here’s how to configure the UFW firewall.
If UFW is not already installed on your system, install it with the following command:
sudo apt install ufw
Activate UFW by typing the following command in the terminal:
sudo ufw enable
Allow traffic on ports 80 (HTTP) and 443 (HTTPS) to access the NGINX web server. Run the following commands:
sudo ufw allow 'Nginx Full' sudo ufw reload
To check that the rules are correctly defined, use the command :
sudo ufw status
The result is :
Make sure traffic is allowed on ports 80 and 443.
Check the available ufw application profiles:
sudo ufw app list
The result is :

After configuring UFW, make sure you can access the NGINX home page in your web browser by navigating to the IP address of your server:
Or, try accessing localhost:
The default NGINX landing page should appear if everything has been configured correctly.
By following these steps, you’ve learned how to install NGINX on Ubuntu. Make sure you configure the server to your specific needs and regularly check for security and performance updates for NGINX.
