Quick Start

Installation / 安装

Current Version: v2.9.8

Included Kernels (Switchable in Panel):

• Stable: v0.4.6 (Tokio) - Recommended for production
• XDP Firewall: v0.6.0-xdp - Anti-DDoS/Flood protection (Kernel 5.4+)

bash <(curl -fsSL https://raw.githubusercontent.com/undead-undead/x-ui-lite/main/install.sh)

Note: This is a static compilation version that works perfectly on any Linux system.

注意：

• 脚本默认安装稳定版内核。
• 如需 XDP 防火墙模式，请在面板的【系统状态】->【切换版本】中选择对应版本。

XDP Firewall (Optional) / XDP 防火墙（可选）

If you switch to v0.6.0-xdp in the panel:

• XDP Firewall: Kernel-level protection against UDP Floods, TCP SYN Floods (Rate Limit) & Illegal Flags.
• Anti-Probe: Instantly drops UDP Floods and Illegal TCP Packets (e.g., Null Scan, SYN+FIN).
• Adaptive Egress Pacing (TC eBPF): Microsecond-precision traffic smoothing to eliminate proxy-burst timing fingerprints.
• Performance: Drop malicious packets at driver level, saving CPU.

Requirements for XDP: Linux Kernel ≥ 5.4, Root Privileges. XDP is automatically enabled if supported kernel is detected and XDP version is selected.
