Nginx Add Server: Everything You Need to Know

Introduction: What is Nginx?

Welcome to our guide on Nginx add server, where we explore the ins and outs of this popular web server and proxy server software. Nginx is an open-source, high-performance web server software that can also act as a reverse proxy, load balancer, and HTTP cache. Initially, Nginx was designed for handling high-traffic websites, but it has since expanded its capabilities to include application servers and content management systems. Nginx is known for its speed, scalability, and security, making it a popular choice for websites around the world.

If you are looking to add a server to your Nginx configuration, you have come to the right place. In this article, we will discuss everything you need to know about Nginx add server, including its advantages and disadvantages, and offer a step-by-step guide to adding a server to your Nginx configuration. Let’s get started!

What is a Server Block in Nginx?

Before we dive into the specifics of adding a server to your Nginx configuration, it is important to understand what a server block is. In Nginx, a server block is a section of the configuration file that defines how Nginx should handle incoming requests for a particular website or application. A typical server block includes the server name, the root directory where the website files are located, and any additional directives that control how Nginx should handle the requests.

How to Add a Server to Nginx?

Now that you have a basic understanding of what a server block is, let’s take a look at how to add a server to your Nginx configuration. The process of adding a server to your Nginx configuration involves three main steps:

1. Create a new server block in the Nginx configuration file
2. Configure the new server block with the appropriate settings
3. Test the new server block and reload the Nginx configuration

Step 1: Create a New Server Block

The first step is to create a new server block in the Nginx configuration file. You can do this by opening the Nginx configuration file using your preferred text editor, located at /etc/nginx/nginx.conf, and adding a new server block at the bottom of the file.

Here is an example of a basic server block:

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

This server block listens on port 80 for requests to the domain example.com. The root directory for the website files is located at /var/www/example.com, and the default index file is index.html. You can modify these settings to match your specific server configuration.

Step 2: Configure the New Server Block

The next step is to configure the new server block with the appropriate settings for your server. This includes defining the server name, root directory, and any additional directives that control how Nginx should handle the requests.

Here are some additional directives that you may want to include in your server block:

Directive	Description
access_log	Defines the location and format of the access log file
error_log	Defines the location and format of the error log file
location	Defines how Nginx should handle requests for a specific URL location
proxy_pass	Defines the location of the backend server for reverse proxy requests

For example, here is a server block that includes additional directives for logging and reverse proxy:

Server Block
server {     listen 80;     server_name example.com;     root /var/www/example.com;     index index.html;     access_log /var/log/nginx/example_access.log;     error_log /var/log/nginx/example_error.log;     location /api {         proxy_pass http://backend_server;     } }

This server block includes an access log and error log file, as well as a location directive that defines how Nginx should handle requests to the /api URL location by reverse proxying them to a backend server at http://backend_server.

Step 3: Test the New Server Block and Reload the Nginx Configuration

The final step is to test the new server block and reload the Nginx configuration. You can test the new server block by running the following command:

sudo nginx -t

If there are no errors in the Nginx configuration, you can reload the Nginx configuration by running the following command:

sudo systemctl reload nginx

Once the Nginx configuration is reloaded, your new server block will be active and ready to handle incoming requests.
