🚀 Server Optimizer

An interactive, colorful, and safe CLI tuning tool for dedicated servers and VPS — by PingLess.ORG aka AnAverageBeing.

A single TUI-driven script that detects your hardware and applies conservative, reversible performance, security, and resource-limit tuning. No more memorizing sysctl keys or editing config files by hand.

---

⚡ One-Line Installer

Run the interactive optimizer directly from GitHub:

bash <(curl -fsSL https://raw.githubusercontent.com/AnAverageBeing/Server-Optimizer/main/install.sh)

Or with wget:

bash <(wget -qO- https://raw.githubusercontent.com/AnAverageBeing/Server-Optimizer/main/install.sh)

Note: Run as root. The script will refuse to start otherwise for safety.

✨ What It Does

• Auto-detects your CPU, NICs, kernel, and vcore count.
• Colorful terminal UI with dialog/whiptail and a colored text fallback.
• Dedicated Server and VPS modes.
• Performance tuning: BBR, CPU governor, IRQ balance, RPS/XPS, NIC queues/rings.
• Security hardening: SYN cookies, rp_filter, ICMP/source-route blocking, kernel restrictions.
• Resource limits: file-max, pid_max, nofile/nproc limits, systemd service limits.
• Swap management: ZRam or disk swap with size input.
• Dry-run mode: preview every change before it happens.
• Rollback: restore previous settings with one menu option.
• Idempotent: run it once or ten times — no duplicate entries.
• Cross-distro: supports apt, dnf, yum, pacman, and apk.

🛡️ Safety First

The script never touches:

• RAID topology
• ZFS pool layout
• CPU voltage / PBO / Curve Optimizer
• Kernel security mitigations
• C-states (automatically)
• VM configurations
• XDP/eBPF programs
• MTU / IP addresses / routing / firewall rules

Every file the script modifies is backed up to /var/lib/auto-host-optimize/backup/ before the first change.

---

📋 Requirements

• Linux (kernel 5.15+)
• root privileges
• bash
• Internet connection for dependency installation (optional if deps already present)

---

🔄 Rollback

From the main menu choose Rollback, or run:

/root/auto-host-optimize.sh
# then select Rollback

This removes all created sysctl files, systemd services, limits, and swap configuration.

---

🧪 Dry Run

Before applying anything, enable Dry-Run Mode in the main menu. The script will print every command it would run without modifying your system.
