Nginx Server Multiple Domains – The Ultimate Guide

Introduction

Welcome to our ultimate guide on Nginx server multiple domains. In this guide, we will provide you with a detailed explanation of Nginx, multiple domains, and how to configure Nginx to host multiple domains on a single server.

If you’re not familiar with Nginx, it’s a popular web server that’s known for its high performance and ability to handle large amounts of traffic. Additionally, it’s also known for its flexibility and ability to be configured for a variety of use cases.

Multiple domains, on the other hand, refer to hosting multiple websites on a single server. This can be a cost-effective solution for small to medium-sized businesses that want to host multiple websites but don’t want to invest in separate servers for each site.

In the following sections, we will explore the benefits and drawbacks of hosting multiple domains on an Nginx server and provide you with a step-by-step guide on how to configure Nginx for multiple domains.

What is Nginx?

Nginx (pronounced ‘engine-x’) is an open-source web server that can also function as a reverse proxy, load balancer, and HTTP cache. Originally created to handle high traffic for Russian search engine Rambler in 2002, it has since become one of the most popular web servers in the world, with over 435 million websites using it as of May 2021.

One of the reasons for Nginx’s popularity is its ability to handle a high volume of traffic with minimal resource utilization. Unlike other web servers, which create a new process or thread for each connection, Nginx uses an event-driven, asynchronous architecture that allows it to handle multiple connections simultaneously with minimal resource usage.

Hosting Multiple Domains on an Nginx Server

Hosting multiple domains on an Nginx server is a great way to save money on server costs while still being able to host multiple websites. In the following sections, we will provide you with a step-by-step guide on how to host multiple domains on a single Nginx server.

Step 1: Installing Nginx

The first step in hosting multiple domains on an Nginx server is to install Nginx. To do this, you can use your server’s package manager or download the latest version from the Nginx website.

Once you have installed Nginx, you can start the service by running the following command:

sudo systemctl start nginx

Step 2: Configuring DNS

The second step in hosting multiple domains on an Nginx server is to configure your domain’s DNS settings. This involves setting up an A record that points to your server’s IP address.

You can do this through your domain registrar’s website or by editing your server’s DNS zone file.

Step 3: Configuring Nginx for Multiple Domains

The third step in hosting multiple domains on an Nginx server is to configure Nginx to serve multiple domains. To do this, you can create a new server block for each domain you want to host.

Here is an example server block configuration for hosting multiple domains:

server {listen 80;server_name example.com;root /var/www/example.com;index index.html;}server {listen 80;server_name example2.com;root /var/www/example2.com;index index.html;}

Each server block specifies the domain name, the root directory where the website files are located, and the default file to serve when a visitor accesses the site.

Step 4: Testing Your Configuration

The final step in hosting multiple domains on an Nginx server is to test your configuration. To do this, you can use the following command:

sudo nginx -t

If your configuration is valid, you should see the following output:

nginx: configuration file /etc/nginx/nginx.conf test is successful
