In this comprehensive tutorial, we’ll delve into the world of NGINX and explore the process of adding a domain. By the end of this article, you’ll be equipped with the knowledge and skills necessary to configure your NGINX server like a pro.

What is NGINX?

Before diving into the nitty-gritty of adding a domain to NGINX, let’s take a step back and explore what NGINX actually is. NGINX (pronounced “engine-x”) is a popular open-source web server software that can also be used as a reverse proxy, load balancer, and HTTP cache. Its primary function is to serve web content, such as HTML pages, images, and videos, over the HTTP protocol.

Why Add a Domain to NGINX?

Adding a domain to NGINX is essential for serving websites and web applications on the internet. When you add a domain, you’re telling NGINX which website or application it should serve when a user requests a specific URL. This allows multiple websites to be hosted on a single server, making it an efficient and cost-effective solution.

Step-by-Step Guide to Adding a Domain to NGINX

Step 1: Create a New Configuration File

To add a domain to NGINX, you’ll need to create a new configuration file. This file will contain the necessary settings for your website or application.

Create a new file in the /etc/nginx/sites-available/ directory called example.com.conf. Replace example.com with your actual domain name.

sudo nano /etc/nginx/sites-available/example.com.conf

Step 2: Define the Server Block

In this step, you’ll define the server block for your domain. The server block contains settings that are specific to a particular website or application.

Add the following code to the example.com.conf file:

server {
    listen 80;
    server_name example.com www.example.com;

    root /var/www/example.com/html;
    index index.html index.htm;
}

Here’s what each line does:

• listen 80;: Specifies the port number that NGINX should listen on.
• server_name example.com www.example.com;: Defines the server name, which is the domain name or IP address of your website or application.
• root /var/www/example.com/html;: Specifies the root directory of your website or application.
• index index.html index.htm;: Defines the index files that NGINX should serve when a user requests the root URL.

Step 3: Create a Symbolic Link

To enable the new configuration file, you’ll need to create a symbolic link in the /etc/nginx/sites-enabled/ directory.

Run the following command:

sudo ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/

Step 4: Test the Configuration

Before reloading NGINX, it’s essential to test the configuration file for any errors.

Run the following command:

sudo nginx -t

If there are no errors, you’ll see a message indicating that the configuration is valid.

Step 5: Reload NGINX

Finally, reload NGINX to apply the new configuration.

Run the following command:

sudo service nginx reload

Conclusion

Adding a domain to NGINX is a straightforward process that requires creating a new configuration file, defining the server block, creating a symbolic link, testing the configuration, and reloading NGINX. By following these steps, you’ll be able to serve your website or application on the internet using NGINX.

Summary of Key Points:

• Create a new configuration file in the /etc/nginx/sites-available/ directory.
• Define the server block with settings specific to your website or application.
• Create a symbolic link in the /etc/nginx/sites-enabled/ directory.
• Test the configuration file for errors using nginx -t.
• Reload NGINX using service nginx reload.
