Installing Nginx on Ubuntu, combined with UFW

Installing Nginx on a newer Ubuntu is easy. Just follow the steps below. The guide indicates version 20.04. I used it on 22.10.

If you are not aware on your exact version of Ubuntu, see my TIL: How to enquire Ubuntu version.

sudo apt update
sudo apt install nginx

sudo ufw app list
Available applications:
  Nginx Full
  Nginx HTTP
  Nginx HTTPS
  OpenSSH

Nginx Full: This profile opens both port 80 (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted traffic)

Nginx HTTP: This profile opens only port 80 (normal, unencrypted web traffic)

Nginx HTTPS: This profile opens only port 443 (TLS/SSL encrypted traffic)

sudo ufw allow 'Nginx Full'

sudo ufw status
Status: active

To                         Action      From
--                         ------      ----
Nginx HTTP                 ALLOW       Anywhere
443                        ALLOW       Anywhere
Nginx HTTP (v6)            ALLOW       Anywhere (v6)
443 (v6)                   ALLOW       Anywhere (v6)

sudo systemctl status nginx
...

Get your public IPv4 address from icanhazip.com.

curl -4 icanhazip.com

```bash
curl -6 icanhazip.com

Open the URL in your browser. You should see the default Nginx page.

curl http://<your-public-ipv4-address>
