DigitalOcean Setup Nginx Server Blocks: Simplified Guide

🚀 Introduction

Greetings to all of our readers! The world of technology constantly evolves, and we are here to provide you with the latest trends and updates. One of the popular tools in web server architecture is Nginx. In this article, we will guide you on how to set up your DigitalOcean server blocks using Nginx, a powerful web server that can handle heavy traffic with ease. Nginx is an open-source software that can be integrated seamlessly with a variety of web application frameworks and programming languages.

If you are planning to host multiple websites or applications on one server, using server blocks is the best way to do so. Server blocks allow you to host multiple websites or applications on one server using the same IP address and port number. This guide will show you how to create a server block in your Nginx configuration file step-by-step.

🧭 Step 1: Creating a Server Block Configuration File

The first step is to create a server block configuration file for each website or application you want to host on your server. The configuration files should be placed in the /etc/nginx/sites-available/ directory. You can use any text editor to create the configuration file, for example:

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

Replace “example.com” with the domain name or application name you want to host.

The configuration file should contain the following:

server {listen 80;listen [::]:80;root /var/www/example.com/html;index index.html index.htm index.nginx-debian.html;server_name example.com www.example.com;location / {try_files $uri $uri/ =404;}}

🧭 Step 2: Enabling the Server Block

The next step is to create a symbolic link to the configuration file in the sites-enabled directory. You can do this by typing:

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

This will enable the server block. To ensure that the syntax of the configuration file is correct, you can run:

sudo nginx -t

If there are no errors, you can restart Nginx by running:

sudo systemctl restart nginx

🧭 Step 3: Checking the Server Block

You can now check if the server block is working correctly by visiting your domain or application in your web browser. If you see the content of the index.html file specified in the configuration file, then everything is working correctly!

🧭 Step 4: Adding SSL Certificate

To secure your website or application, you can add an SSL certificate to your server block. You can obtain a free SSL certificate from Let’s Encrypt by following these steps:

1. Install Certbot by running:

   sudo apt install certbot python3-certbot-nginx -y

2. Obtain a certificate by running:

   sudo certbot --nginx -d example.com -d www.example.com

3. Restart Nginx by running:

   sudo systemctl restart nginx

🧭 Step 5: Disabling the Default Server Block

By default, Nginx has a default server block that listens on port 80. To avoid conflicts, we should disable this server block by running:

sudo unlink /etc/nginx/sites-enabled/default
