How to Configure Nginx on Ubuntu 23.04


Configuring Nginx on Ubuntu 23.04 is a vital skill for anyone looking to set up a web server. Nginx is renowned for its efficiency, speed, and versatility. In this comprehensive guide, we will take you through the process of configuring Nginx. This guide is designed to be straightforward, even if you’re new to web server administration.

Why Nginx on Ubuntu 23.04?

Ubuntu 23.04 is a robust platform for hosting web services, and Nginx complements it perfectly. Nginx is fast, efficient, and capable of handling numerous concurrent connections. Whether you’re running a personal blog, an e-commerce site, or a complex web application, Nginx on Ubuntu 23.04 offers the performance, security, and flexibility you need.


Step 1: Installation

Your journey begins with the installation of Nginx on your Ubuntu 23.04 server. Open a terminal and execute the following commands:


sudo apt update
sudo apt install nginx

Nginx should start automatically once the installation is complete. You can confirm its status with:

sudo systemctl status nginx


Step 2: Basic Server Testing

After installation, it’s a good practice to perform a basic test to ensure that Nginx is functioning correctly. Open a web browser and enter your server’s IP address or domain name. You should see the default Nginx welcome page.

This confirms that your Nginx web server is up and running.

Step 3: Server Block Configuration

In most cases, you’ll want to host multiple websites or applications on a single server. To achieve this, you’ll configure server blocks in Nginx (similar to virtual hosts in Apache) to route incoming requests to the appropriate site or application.

Configuring Nginx Server Blocks:

Begin by creating a new server block configuration file for each site or application you want to host. These files are typically stored in the /etc/nginx/sites-available/ directory. Here’s an example of creating a server block file:


sudo nano /etc/nginx/sites-available/

Inside the file, configure the server block. Here’s a basic example:

server {
    listen 80;
    root /var/www/html/example;
    index index.html;

    location / {
        try_files $uri $uri/ =404;

After creating the server block configuration, create a symbolic link to enable it and test the configuration:

sudo ln -s /etc/nginx/sites-available/ /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx

Step 4: Website Deployment and Configuration

With your server blocks set up, you can now deploy your website or web application to the appropriate document root directory specified in your server block configuration. Additionally, you may need to configure database connections, content management systems, or application settings depending on your specific use case.

Step 5: Domain Configuration

If you have a domain name, you’ll need to configure its DNS settings to point to your server’s IP address. This is typically done through your domain registrar’s control panel. Ensure that your domain name resolves to your server’s IP address to allow incoming web traffic.

Step 6: SSL/TLS Configuration (Optional)

For enhanced security, consider configuring SSL/TLS certificates to enable encrypted connections (HTTPS). While this step is optional, it’s highly recommended, especially for e-commerce sites and applications that handle sensitive data.

You can obtain free SSL/TLS certificates from Let’s Encrypt and configure Nginx to use them. Detailed instructions for setting up Let’s Encrypt can be found in the official documentation.


Configuring Nginx on Ubuntu 23.04 empowers you to host websites, applications, and services with speed and efficiency. By mastering Nginx configuration, you can confidently create and manage your web hosting environment, ensuring the reliability, security, and performance of your online services.

Nginx’s reputation for speed and versatility, combined with Ubuntu 23.04’s reliability, makes this combination an excellent choice for various web hosting scenarios. Whether you’re a seasoned web administrator or just starting, this guide equips you with the skills needed to set up a powerful web server.
