3. Nginx Server Setup

Now that i) we have configured a generic Linux server on your machine depending on the OS you’re runningii)created a user that can access to this server, we will now move on to the next step.

In this guide, we’ll discuss cover how to install Nginx (a webserver) on your Ubuntu 18.04 server.

What is Nginx?

Nginx is one of the most popular web servers currently being used and hosts some of the highest-traffic sites on the internet. It is really resource-friendly and can be used as a web server or reverse proxy. To know more about Nginx please click here

  1. Open terminal in Ubuntu

  2. TYPE the following commands

    Code Block
    $ sudo su 
$ [sudo] password for 'username': 
# once you've entered your password you will have root permissions

  3. Installing Nginx

    Code Block
    $ sudo apt update
$ sudo apt install nginx
#After accepting the procedure, apt will install Nginx and any required dependencies to your server.

  4. Adjusting the Firewall

    Code Block
    $ sudo ufw app list
#You should get a listing of the application profiles:

output:
Available applications:
  Nginx Full
  Nginx HTTP
  Nginx HTTPS
  OpenSSH
# Nginx HTTP: This profile opens only port 80 (normal, unencrypted web traffic). You need to enable this
 
$ sudo ufw allow 'Nginx HTTP'
#You can verify by typing 
$ sudo ufw status

output:
Status: active
