How To Install Nginx on Ubuntu Server: 4 Simple Steps

This guide covers an easy to follow, step-by-step guide on how to install Nginx on Ubuntu Server 18.04 LTE, 16.04, and 14.04. While writing this tutorial I used Ubuntu 18.04 LTE though these resources in the tutorial are useful in installing Nginx on Ubuntu 16.04 and 14.04 as well.

Nginx is a high-performance web server and reverse proxy that has become a top choice for developers and system administrators worldwide. Known for its speed, stability, and efficient resource usage, Nginx allows your server to handle thousands of simultaneous connections with minimal overhead. Whether you are hosting a personal website, deploying web applications, or configuring a reverse proxy, learning how to properly install and configure Nginx on Ubuntu is an essential skill.

In this tutorial, we will walk you through the entire Ubuntu Nginx setup, including installing the server, verifying the installation, and performing basic Nginx server configuration to ensure your web environment is secure and ready to serve content.

By following this guide, you will have a fully functional Nginx server on your Ubuntu system, optimized for performance and prepared to handle real-world web traffic efficiently.

Prerequisites

Before we begin the installation of Nginx on Ubuntu, there are a few requirements to ensure a smooth setup process:

• Ubuntu Server – You should have a running instance of Ubuntu 18.04 LTE, 16.04, or 14.04. This guide is tested on Ubuntu 18.04 LTE, but the steps apply to the other supported versions as well.
• Root or Sudo Access – You need to have root privileges or a user account with sudo permissions to install software packages and make system-level changes.
• Basic Command-Line Knowledge – Familiarity with the Linux terminal will help you execute commands efficiently and troubleshoot minor issues during the installation process.
• Updated System Packages – It’s recommended to update your system packages to the latest versions before installing Nginx. You can do this using: sudo apt update sudo apt upgrade
• Firewall Configuration (Optional but Recommended) – If your server has a firewall enabled, you’ll need to allow HTTP (port 80) and HTTPS (port 443) traffic so Nginx can serve web pages.

With these prerequisites in place, you’re ready to start the Ubuntu Nginx setup and get your web server up and running.

How To Install Nginx on Ubuntu Server: Step-by-step

Step 1 - Install Nginx on Ubuntu

Once you are done updating your server, install Nginx on Ubuntu from its default repository using the apt packaging system by running the following command:

sudo apt-get install nginx

Step 2 – Configure the Firewall

Before testing the Nginx installation on Ubuntu, let’s first adjust the firewall to allow access to the service. Nginx by default registers itself as a service with ufw.

You can check the status by running the following command:

Output
Available applications:
  Nginx Full
  Nginx HTTP
  Nginx HTTPS
  OpenSSH

Nginx Full: It means the port 80 is open (normal, unencrypted web traffic) and port 443 (TLS/SSL encrypted) are open for http protocol. So that anyone can access the web server by entering the IP address in the web browser.

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

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

It is important that we enable all the required profiles for HTTP and HTTPS.

You can see the status by running the following command:

sudo
ufw status

You should see the allowed HTTP and HTTPS traffic. You can see the output below:

Status: active

To                          Action       From
--                          ------       ----
Nginx Full                  ALLOW        Anywhere
Nginx HTTP                  ALLOW        Anywhere
Nginx HTTPS                 ALLOW        Anywhere
Nginx Full (v6)             ALLOW        Anywhere (v6)
Nginx HTTP (v6)             ALLOW        Anywhere (v6)
Nginx HTTPS (v6)            ALLOW        Anywhere (v6)

Step 3 - Checking Your Server

Now you can check the status of your Nginx web server by typing the following command in the terminal:

systemctl status nginx

● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: en
   Active: active (running) since Thu 2019-01-24 13:12:02 IST; 5 days ago
  Process: 22119 ExecStop=/sbin/start-stop-daemon --quiet --stop --retry QUIT/5
  Process: 22125 ExecStart=/usr/sbin/nginx -g daemon on; master_process on; (cod
  Process: 22122 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process
 Main PID: 22127 (nginx)
   CGroup: /system.slice/nginx.service
           ├─22127 nginx: master process /usr/sbin/nginx -g daemon on; master_pr
           └─22128 nginx: worker process

Warning: Journal has been rotated since unit was started. Log output is incomple
lines 1-12/12 (END)

We can see that Nginx is started successfully.

So now you need to put the IP address of your server in the web browser to see the Nginx welcome page.

In case you don’t know the IP address of your server, run the following command to display the IP address:

ip addr show
eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

Now when you enter the IP address of your server in the browser, you get to see the Welcome page by Nginx.

If you see the above page successfully by running the IP address in the browser, mean that Nginx is configured correctly.

Step 4 – Managing Nginx and its Processes

Below are some of the very useful command that you will need while managing Nginx on your server.

To stop your web server:

sudo
systemctl stop nginx 

or

sudo
service nginx stop

or

sudo
/etc/init.d/nginx stop

To start the web server:

sudo
systemctl start nginx 

or

sudo
service nginx start

or

sudo
/etc/init.d/nginx start

To restart the web server:

sudo
systemctl restart nginx

or

sudo
service nginx restart

or

sudo
/etc/init.d/nginx restart

To reload the Nginx without dropping the connection you can run the reload command:

sudo
systemctl reload nginx

or

sudo
service nginx reload

or

sudo
/etc/init.d/nginx reload

In any case, if you need to disable your web server, you might want to run the disable command:

sudo
systemctl disable nginx

To enable web server:

sudo
systemctl enable nginx

That’s it!

You are done installing and configuring Nginx web server. For more information regarding Nginx documentation, check official documentation by Nginx.

Bonus: How to Uninstall Nginx on Ubuntu

While Nginx is a reliable and lightweight web server, there may be situations where you need to remove it from your Ubuntu system—whether to troubleshoot issues, switch to a different web server, or start fresh. Here’s a simple guide to uninstall Nginx safely.

Step 1: Stop the Nginx Service

Before uninstalling, stop Nginx to ensure no processes are running:

sudo systemctl stop nginx

Step 2: Remove Nginx Packages

To remove Nginx without deleting configuration files, use:

sudo apt remove nginx

If you want to remove Nginx along with its configuration files, use the purge command:

sudo apt purge nginx

Step 3: Remove Unused Dependencies

After removal, you can clean up any unused packages and dependencies:

sudo apt autoremove

Step 4: Verify Removal

Check if Nginx has been completely removed:

nginx -v

If Nginx is uninstalled, you will see a command not found error.

Optional: Remove Nginx Directories

If you want to completely clean up your server, you can delete remaining Nginx directories:

sudo rm -rf /etc/nginx
sudo rm -rf /var/www/html

By following these steps, you can safely uninstall Nginx from your Ubuntu system and prepare it for a fresh installation or alternative web server setup.
