Unveiling Subdomain and Subdirectory Virtual Hosting in Nginx

When it comes to web hosting, Nginx has established itself as a reliable and high-performance web server. One of its powerful features is the ability to set up virtual hosts, allowing you to host multiple websites on a single server. This article will delve into the concepts of subdomain and subdirectory virtual hosting using Nginx, offering a comprehensive guide to effectively manage your web hosting needs.

Subdomain Virtual Hosting

What are Subdomains?

Subdomains are an essential part of domain hierarchy, enabling you to create separate sections of your website with unique content and functionality. A subdomain appears as a prefix to your primary domain in a URL, like subdomain.example.com. This separation is particularly useful for organizing and maintaining various services or sections of a website.

Setting up Subdomain Virtual Hosts in Nginx

Configuring subdomain virtual hosts in Nginx involves creating separate server blocks for each subdomain. In the Nginx configuration file, you define server blocks using the server directive and specify the server_name directive to associate each server block with a subdomain. This approach ensures that incoming requests are routed to the appropriate subdomain’s content directory.

Subdirectory Virtual Hosting

Understanding Subdirectory Hosting

Unlike subdomains, which use prefixes in the URL, subdirectories are segments of the URL path that come after the domain, like example.com/subdirectory. Subdirectory hosting is useful when you want to maintain multiple websites within the same domain, each residing in its own subdirectory.

Configuring Subdirectory Virtual Hosts

To set up subdirectory virtual hosts, you’ll need to use the location directive within your Nginx server block configuration. This directive allows you to define specific rules for how requests to different subdirectories should be handled, including proxying to different backend services or serving static content.

Benefits and Considerations

Advantages of Subdomains

Subdomains offer a clear separation between different sections of your website, making management and maintenance easier. They also allow for independent configuration, such as different SSL certificates or authentication settings for each subdomain.

Advantages of Subdirectories

Subdirectories can be more straightforward to set up since they don’t require the same level of DNS configuration as subdomains. Additionally, they share the same SSL certificate, IP address, and port with the main domain, simplifying the setup process.

Considerations for Choosing

The decision between subdomain and subdirectory hosting depends on factors like the structure of your website, your content organization strategy, and your technical requirements. Carefully assess the pros and cons of each approach before making a choice.


In this guide, we’ve explored the concepts of subdomain and subdirectory virtual hosting using Nginx. Whether you opt for subdomains or subdirectories, Nginx provides the tools to efficiently manage multiple websites on a single server. By understanding these techniques and their implications, you’ll be better equipped to make informed decisions about your web hosting strategy.
