How to configure nginx on ubuntu 20.04

Nginx is an open source software for web serving ( nginx on ubuntu 20.04 ) like Apache. You can check how to config apache in here . It uses a single-threaded architecture and is designed for maximum performance and stability. So it is more efficient than Apache if configured correctly. In addition to HTTP server capabilities. NGINX can also act as a proxy server for email (POP3, SMTP, …), a load balancer and reverse proxy for HTTP, TCP and UDP servers.

Step 1: Install Nginx on ubuntu 20.04

Since Nginx is available in the Ubuntu repositories, you can directly install Nginx using the apt package management and installation system. First, proceed to update the packages in the system:

sudo apt install -y update

Install Nginx for your Ubuntu server:

sudo apt install -y nginx

Check Nginx version:

sudo nginx -v

nginx version: nginx/1.17.10 (Ubuntu)

Allow Nginx to start on system:

sudo systemctl enable nginx

Start and check the status of the Nginx service:

systemctl start nginx 
systemctl status nginx

Step 2: Configure the firewall

Use ufw to know how to use firewall configuration for Nginx :

sudo ufw app list 

Available applications:
  CUPS
  Nginx Full
  Nginx HTTP
  Nginx HTTPS
  OpenSSH

We see that for nginx, there are 3 possible configurations to configure for nginx. But currently I do not have a configuration to use SSL for the website, so I only allow traffic to go through port 80.

Enable the above using the following command:

sudo ufw allow 'Nginx HTTP'

Then test the change again with the following command:

sudo ufw status

Step 3: Check the website

To test the website, open a browser and enter the ip address of the Nginx server.
