This repository contains a script for automating the installation and renewal of Let's Encrypt SSL certificates on Linux servers using Nginx. It simplifies the setup of SSL on Nginx by handling all necessary installations, configurations, and renewals automatically.

Features

• Automated SSL Certificate Installation: Sets up SSL certificates from Let's Encrypt for your domain hosted on Nginx.
• Domain Resolution Check: Ensures your domain resolves correctly before installation to prevent errors.
• Backup Option: Offers an option to backup existing Nginx configurations before making changes.
• Automated Renewals: Configures cron jobs to handle certificate renewals automatically.
• Cross-Distro Support: Supports both Debian and Fedora-based Linux distributions.

Prerequisites

Before running this script, ensure the following:

• You are using a Linux server running either a Debian-based (like Ubuntu or Debian itself) or Fedora-based (like Fedora or CentOS) distribution.
• You have root or sudo privileges on the server.
• Nginx is installed and running.
• DNS utilities are available (dnsutils for Debian-based systems or bind-utils for Fedora-based systems).

Installation

Clone the repository

Change to the directory
