Nginx 2 Different Default Server: A Comprehensive Guide

Introduction

Welcome to our comprehensive guide on Nginx 2 different default server. If you are looking for an HTTP server with high performance and low resource utilization, Nginx is the way to go. Nginx is a widely used web server that is known for its scalability, stability, and flexibility. With Nginx, you can create and manage multiple websites or applications on a single server. One of the most interesting features of Nginx is its ability to support two different default servers. In this guide, we will be discussing this feature in detail, including its advantages and disadvantages.

Before we dive into the topic, we must first understand what a default server is and how it works. In Nginx, a default server is a server that will be used to handle requests that do not match any of the server names or IP addresses defined in the configuration file. Nginx supports two types of default servers: wildcard default server and IP-based default server.

Explaining Nginx 2 Different Default Server

Nginx 2 different default server is an advanced feature that allows you to use two default servers in your configuration file. By default, Nginx only supports one default server. However, with this feature, you can define one wildcard default server and one IP-based default server. The wildcard default server handles requests that do not match any server name or IP address, and the IP-based default server handles requests that match the server’s IP address.

For example, if you have two websites hosted on the same server, and one of them uses a specific IP address, you can use the IP-based default server for that website, and the wildcard default server for the other website.

Wildcard Default Server

A wildcard default server is a server block that is used to handle requests that do not match any of the server names defined in the configuration file. This server block is defined using an asterisk (*) as the server name. Here’s an example:

Server Block
server {
  listen 80 default_server;
  server_name _;
  root /var/www/example.com;
}

In the above example, the server block listens on port 80, and has a server name wildcard (_) that matches any request that does not match any other server name. The root directory for this server block is /var/www/example.com.

IP-based Default Server

An IP-based default server is a server block that is used to handle requests that match the server’s IP address. This server block is defined using the server’s IP address as the server name. Here’s an example:

Server Block
server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name 192.0.2.1;
  root /var/www/example.com;
}

In the above example, the server block listens on port 80 and has a server name of 192.0.2.1. The root directory for this server block is /var/www/example.com.
