Nginx is the most potent, open-source, and a high-
performance Web server. It can work as a reverse proxy
server also, nowadays, is used by most of the most
significant websites on the internet.
People pronounced “engine x” for Nginx; it is the hot
choice for every website owner to power their site with
Nginx.
In comparison to the Apache web server, Nginx is
capable of handling more connections with a few
amount of memory footprint in each connection.
Prerequisites
Make sure your Linux box does not have an Apache
HTTP server or any application service running on port
80 and 443. You should have sudo privileges to execute
commands on your Linux machine.

INSTALL NGINX
Nowadays, Nginx software packages built-in Ubuntu default
software repository, so the installation is effortless, You just
run the following commands in terminal:
# sudo apt update
# sudo apt install nginx
After installation of Nginx, you can check the status of the
Nginx service by using the following command:
# sudo systemctl status nginx
The output of the above command should show that the Nginx
service is running:
nginx.service - A high performance web server and a
reverse proxy server
Loaded: loaded (/lib/systemd/system/nginx.service;
enabled; vendor preset: enabled)
Active: active (running) since Sun 2020-22-06 15:44:04
UTC; 1min 59s ago
Main PID: 1461 (nginx)
CGroup: /system.slice/nginx.service
├─1461 nginx: master process /usr/sbin/nginx -g
daemon on; master_process on
└─1463 nginx: worker process
You can also check the version of Nginx Web server, using the
following command:
# sudo nginx -v
nginx version: nginx/1.14.0 (Ubuntu)

FIREWALL CONFIGURATION
Today, we all are using the UFW firewall to manage network
connection and traffic on the Ubuntu machine. To use Nginx,
you will need to open HTTP Port (80) and HTTPS port (443).
You can open HTTP and HTTPS port by enabling “Nginx Full”
profile on UFW:
# sudo ufw allow 'Nginx Full'
You can verify the firewall configuration using below
command:
# sudo ufw status
The output of the above command is something like below:
Status: active
To Action From
-- ------ ----
22/tcp ALLOW Anywhere
Nginx Full ALLOW Anywhere
22/tcp (v6) ALLOW Anywhere (v6)
Nginx Full (v6) ALLOW Anywhere (v6)

Nginx Installation Test
You can verify that installed Nginx is working as expected by
opening in your browser with your IP (http://your-IP). You will get
the browser screen with default Nginx welcome page, as shown
below:

Install Nginx using Nginx PPA Repository
The Ubuntu default software repository is not updating
packages regularly, so it often outdated. To install Nginx’s
latest version, use Nginx’s official PPA repository.
To install Nginx using PPA repository in Ubuntu 21.04, follow
below steps:
01. install “software-properties-common” in Ubuntu system
# sudo apt install software-properties-common
02. Add Nginx’s PPA repository using following command
# sudo add-apt-repository ppa:nginx/stable
03. Update package manager with list and install Nginx using
following command:
# sudo apt update
# sudo apt install nginx
04. After completing the installation of Nginx, check the
version of installed Nginx
# sudo nginx -v
nginx version: nginx/1.17.0

Manage Nginx service with systemctl
You can manage Nginx services with the similar command what
use to manage other system services.
Start the Nginx Service:
# sudo systemctl start nginx
Stop the Nginx Service:
# sudo systemctl stop nginx
Restart the Nginx Service:
# sudo systemctl restart nginx
Reload the Nginx Service:
# sudo systemctl reload nginx
Enable the Nginx Service to start at boot:
# sudo systemctl enable nginx
Disable the Nginx Service to not start on boot:
# sudo systemctl disable nginx

The Nginx configuration files will always remain in the
“/etc/nginx/” directory.
The main Nginx’s setting files located at
“/etc/nginx/nginx.conf.”
To keep Nginx configuration is simple by configuring
separate files for each site. You can keep as much as you
want with a configuration file with a server block.
Nginx server block files or site configuration files stored in
the “/etc/nginx/sites-available/” directory. To make these
files in use on Nginx, link the files in the “/etc/nginx/sites-
enable/” directory.
To activate any new site configuration, we need to create a
symlink of site configuration file available in the “sites-
available” directory to the “sites-enabled” directory.
To identify the site’s configuration, follow the standard
naming conversion for server block files. For example, you
have a site testweb.com. It is better to create a file as
“/etc/nginx/sites-available/testweb.com.conf” to identify
quickly when you have multiple sites configured in the Nginx
web server.

There is no boundry to configure domain document root
directory, you can set any location you want. But the most
recommended location for web root directory are:
Conclusion
Congratulation; now you have installed the Nginx Web server
on your Ubuntu 21.04 server. Now, you are ready to deploy
and run your application using Nginx as a web server or
reverse proxy server.
