In this guide, we’ll discuss how to install Nginx on your Ubuntu 18.04 server.

You can follow the steps manually or you can just execute a bash script* and have this setup done for once the script is executed. For that please skip to the bottom of this section.

*Please complete till step 6 to download the Nginx server and check if it has been successfully installed. After this, you can execute the script.

  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 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:
