Multi-Gunbot VPS Deployment Guide

Welcome to the Multi-Instance Gunbot VPS Deployment Guide — a clean, production-ready system for running multiple isolated Gunbot instances on a secure VPS.

🚀 Overview¶

✅ System preparation and security hardening
🧩 Multi-instance isolation for Live and Simulator bots
🔐 Reverse proxy, HTTPS, and automated certificate renewal
⚙️ PM2 + systemd persistence, log rotation, and backups

Designed for Ubuntu 22.04 and tested on real-world deployments.

🧰 Prerequisites¶

Before starting, ensure you have the following:

🧠 Working knowledge of the Linux command line (CLI) — you should be comfortable using ssh, sudo, and editing configuration files.
🌐 A registered domain and two subdomains — for example:
gunbot.your-domain.com and simulator.your-domain.com
(You can substitute any subdomains; these are used throughout this guide for clarity.)
💻 A VPS with SSH access — Ubuntu 22.04 LTS (recommended) or later, with sudo privileges.
🔑 SSH key pair — set up for passwordless authentication to your VPS.
🧩 Basic understanding of Nginx and networking — helpful but not strictly required.
☁️ Root or administrative access to configure firewalls, services, and certificates.

Note: This guide assumes a fresh VPS installation to minimize conflicts with existing configurations.
