Step 1 – Installing Nginx
Because Nginx is available in Ubuntu’s default repositories, it is possible to install it from these repositories using the apt packaging system.
sudo apt update
sudo apt install nginx
Step 2 – Adjusting the Firewall
sudo ufw app list
Output
Available applications:
Nginx Full
Nginx HTTP
Nginx HTTPS
OpenSSH
It is recommended that you enable the most restrictive profile that will still allow the traffic you’ve configured. Right now, we will only need to allow traffic on port 80.
You can enable this by typing:
sudo ufw allow 'Nginx HTTP'
You can verify the change by typing:
sudo ufw status
