How to Set Up Ubuntu Nginx Server

Step 1: Install Ubuntu

The first step in setting up an Ubuntu Nginx server is to install Ubuntu. You can download the latest LTS version of Ubuntu from the official website and follow the installation wizard.

Step 2: Set Up a Firewall

Once you have installed Ubuntu, you need to set up a firewall to protect your server from unauthorized access. Ubuntu comes with a default firewall called UFW (Uncomplicated Firewall). You can enable the firewall with the following command:

sudo ufw enable

Step 3: Install Nginx

With the firewall enabled, you can now install Nginx. You can install Nginx from the official Ubuntu repositories using the following command:

sudo apt-get install nginx

Step 4: Configure Nginx

Once Nginx is installed, you need to configure it to serve your web application. The main configuration file for Nginx is located at /etc/nginx/nginx.conf. You can edit this file with your favorite text editor to add your server blocks and location blocks.

Step 5: Test Nginx

With Nginx installed and configured, you can now test it by visiting your server’s IP address or domain name in your web browser. If you see the default Nginx welcome page, then Nginx is working correctly.

Step 6: Add SSL Certificate (Optional)

If you want to secure your web application with HTTPS, you need to add an SSL certificate. You can obtain a free SSL certificate from Let’s Encrypt or purchase one from a certificate authority. Once you have the SSL certificate, you can configure Nginx to use it in your server blocks.
