🌀 Nginx Install Script (Ubuntu/Debian)

A lightweight Bash script to automate the setup and management of NGINX, domain configuration, Let's Encrypt SSL, and cleanup on Debian-based systems.
🔨🤖🔧 Ideal for developers, sysadmins, or DevOps engineers looking for quick NGINX provisioning.

📦 Features

• ✅ Install and start NGINX if not already installed
• 🌐 Setup new domains with:
  • Custom NGINX configuration
  • Optional Let's Encrypt SSL integration
  • Auto-generated site directory & index.html
  • Optional Certbot cron renewal
• 💥 Remove all NGINX and domain-related settings in one go (NGINX, domain dirs, SSL certs, and cron jobs)

🧰 Usage

mkdir -p uriscript && cd uriscript && curl -O https://raw.githubusercontent.com/urifallon/uriscript-nginx/main/uriscript-nginx.sh
chmod +x uriscript-nginx.sh
./uriscript-nginx.sh

You’ll be greeted with a menu:

Please select an option: 
1) Install NGINX
2) Setup Domain
3) Remove All
4) Exit

🛠️ Options Breakdown

1. Install NGINX

• Installs NGINX if not present
• Starts and enables the service

2. Setup Domain

• Prompts for:
  • Your domain name (e.g. example.com)
  • Whether to enable SSL
  • Whether to create a cron job for SSL renewal
• Creates:
  • /var/www/<yourdomain>/html/index.html
  • NGINX config at /etc/nginx/sites-available/<domain>.conf
  • Symlink in sites-enabled
  • Optional Let's Encrypt certificate with Certbot
• Reloads NGINX on success

3. Remove All

A full teardown of everything the script sets up:

• Removes NGINX and config files
• Deletes domain web root directories
• Deletes SSL certificates via certbot delete
• Removes cron jobs that involve certbot renew

📁 Directory Overview

If you want to manually reconfigure or inspect the setup:

Path	Purpose
/etc/nginx/sites-available/<domain>.conf	Domain's NGINX configuration
/etc/nginx/sites-enabled/<domain>.conf	Symlink to enable config
/var/www/<domain>/html/	Root web content (index.html)
/etc/letsencrypt/live/<domain>/	SSL certs (if Let's Encrypt is enabled)
crontab -e	Certbot auto-renewal job (runs daily at 3AM by default)

To edit domain manually:

sudo nano /etc/nginx/sites-available/<yourdomain>.conf
sudo systemctl reload nginx

To remove a domain:

sudo rm -rf /var/www/<yourdomain>
sudo rm /etc/nginx/sites-available/<yourdomain>.conf
sudo rm /etc/nginx/sites-enabled/<yourdomain>.conf
sudo certbot delete --cert-name <yourdomain>

🧪 Useful Commands

# Test NGINX config syntax
sudo nginx -t

# Reload NGINX after config change
sudo systemctl reload nginx

# View all configured certbot certificates
sudo certbot certificates

# Manually renew SSL (usually done via cron)
sudo certbot renew --dry-run

# View current root crontab
sudo crontab -l

⚠️ Requirements

• OS: Ubuntu/Debian (tested on Ubuntu 20.04+)
• Root or sudo privileges
• Internet access (for package installation and Let's Encrypt)

💡 Notes

• This script does not support wildcard or multi-domain SSL (e.g., *.domain.com)
• Ensure that DNS for the domain is pointing to the server's IP before running SSL setup
• The script is idempotent — re-running it on the same domain will prompt for confirmation

🧼 Cleanup

Want to revert everything? Just choose the Remove All option in the menu and confirm twice.
This removes:

• NGINX
• Domain folders
• Certbot SSL certificates
• Cron jobs related to SSL renewal
